Keeping track of software dependencies is not an easy task and only becomes more difficult as companies scale. In this blog, we explore the types of dependencies and complications they can cause, as well as available tools and best practices organizations can adopt to improve their open source inventory management.

Understanding Software Dependencies

Software dependency management is a hot topic and an ongoing area for learning and process improvements. They are the byproduct of code collaboration and sharing, and all of us who consume and/or contribute to OSS are potential victims of the consequences if dependencies aren’t properly managed. And while not unique to open source software, the rapid proliferation of open source technologies has made tracking software dependencies more complex.

There are two main categories of software dependencies:

• Direct dependencies: This refers to frameworks, libraries, modules, and other software components that an application deliberately and “directly” references to address a solved problem.
• Transitive dependencies: This refers to the cascading list of those independent pieces of software that the direct dependencies in turn include to function properly.

Beyond that, there are some distinctions within those two main categories that are good to be aware of before defining a dependency management strategy:

• Internal vs. External: Some dependencies may be owned and controlled internally by a development team, though typically the vast majority are created and maintained externally.
• Open vs. Closed: Referenced dependencies may be open source allowing development team investigation and ownership by proxy, or they might be binary-only licensed from a vendor where changes are managed through contractual terms.
• Idle vs. Engaged: As the application source evolves, needs change, rendering some dependencies irrelevant. However, they are not always removed from the dependency chain. As a result, some dependencies are actively engaged and used, whereas others are no longer used and remain bundled but idle.

A software inspection methodology that includes inventorying dependencies and managing lifecycles is essential to system security and sustainability. An up-to-date software inventory is necessary for identifying vulnerable or end-of-life components, and identification is the first step in remediating issues and mitigating risks.

The Challenges of Dependency Management

Today there is an ever-increasing demand for both speed and innovation with regards to software development, and that is both the catalyst for, and the result of, open source software. This demand has also produced software delivery concepts like microservices and container orchestration that require vast amounts of integration points – all of which contribute to the chain of software dependencies. This has ushered in a host of software maintenance problems that require dependency management solutions.

The main challenges that arise are due to the pace of change. It is increasingly more difficult for organizations to keep up with evolving software, as well as the companies, communities, and licensing bodies that maintain and govern them. Some examples:

• Version conflicts: When multiple dependencies within the same application require different versions of a shared library.
• Compatibility issues: When updating a package can introduce breaking changes that require modifications to your application to maintain existing functionality.
• Security vulnerabilities: When a downstream dependency has a known security defect that either needs to be addressed by your application or requires an update to the dependency to remediate it.
• End-of-Life problems: When the referenced software package is no longer maintained by the vendor or community, which can result in security defects that are not remediated and leave your application vulnerable to attacks.
• License compliance: When the application uses another software component in a way that is not allowed by the software license. This can sometimes happen as the result of a license change as versions of the dependency are upgraded.
• Idle bloat: When an application has a growing number of unreferenced dependencies that increase the size, complexity, and liability without adding value.

Few developers are privy to all dependency management best practices, and most teams are not equipped with the tooling necessary to mount a proactive approach to avoid dependency problems. Gone are the days when a development team would settle on a single programming language that allowed them to use a particular package manager (e.g. python:pip, java:maven, javascript:npm, rpm:yum) to list the dependency tree, checklists to track the inventory, and unit tests to validate upgrades. Professionalizing a software development practice now requires modern systems for tackling software dependency management at scale.

Let’s Talk

How to Track Software Dependencies and Manage Your Open Source Inventory

Unfortunately as of this writing, there is no silver bullet in this space. In fact, there is not even a best-in- class solution that has emerged. The good news is, there are software organizations and communities that recognize the problem, and are developing strong solutions to address pieces of this puzzle. Gluing them together can produce an effective system, which is the best path forward for now.

Software Dependency Management Tools

There are a few cornerstone tools that lay the foundation for a modern software dependency management system:

• A central code repository that supports revision control and release versioning (e.g. Git, Github, Gitlab, Helix Core). This is the foundation for dependency discovery, and it can also save and manage lock files that tie an application to a specific version of a dependency.
• A package manager for each programming language or platform (e.g. python:pip, java:maven, javascript:npm, rpm:yum). These tools will handle the interactions (push, pull, install, update, list, etc.) with a dependency repository.
• A Software Bill of Materials (SBOM) generator (Syft, SBOM Tool, Tern, CycloneDX). This will produce an attributed inventory of all the software components in your applications (including supplier name, component name, component author, component version, dependency relationship, governing license(s), etc.).
• A vulnerability scanner that supports scheduled detection scans and notification schemes (e.g. Trivy, Grype). This tool will schedule automatic scans that identify security issues and provide detailed reports (i.e. risk prioritization, remediation guidance) that help assess the impact to all direct and transient dependencies referenced by your application.

6 Dependency Management Best Practices

The tools above should be augmented by some best practices that can be implemented and enforced through internal policies, processes, and procedures. These six best practices are a good place to start:

1. Create a central artifact repository to capture the software inventory with key attributes, notes, and links to additional details in related systems (i.e roadmapping, issue tracking systems, risk management, contracts).
2. Define a clear dependency policy that lists acceptable and unacceptable sources and specific approved lists of software components, along with guidelines for gaining approval for components that fill new needs.
3. Establish update and upgrade policies that describe the tooling used to scan for dependency vulnerabilities and lifecycle attributes with guidance on how to prioritize, schedule, and apply/defer the scanner’s findings.
4. Develop a training curriculum to educate developers and others in the organization on the need for ongoing diligence around dependency management and the topics, tools, and techniques required to deliver and maintain a healthy application.
5. Adopt a versioning scheme (i.e. semantic versioning) that allows the organization to track the alignment of dependencies to a particular version of an internal application.
6. Require formal code reviews and testing that includes a dependency review geared toward heading off the common challenges identified above (e.g. version conflicts – idle bloat).

Final Thoughts

Software has become progressively more complex and the need for speed has driven more code-sharing and reuse. Developers have to rely on available packages to handle solved problems, so they can focus on new challenges that advance their particular mission. And unfortunately, sometimes tracking all the dependencies in those packages gets lost in the DevOps shuffle. Hopefully, this blog offers some actionable steps to make your approach to dependency and open source inventory management a little more sophisticated.

Apache Spark vs. Hadoop isn’t the 1:1 comparison that many seem to think it is. While they are both involved in processing and analyzing Big Data, Spark and Hadoop are actually used for different purposes. Depending on your Big Data strategy, it might make sense to use one over the other, or use them together.

In this blog, our expert breaks down the primary differences between Spark vs. Hadoop, considering factors like speed and scalability, and the ideal use cases for each.

What Is Apache Spark?

Apache Spark was developed in 2009 and then open sourced in 2010. It is now covered under the Apache License 2.0. Its foundational concept is a read-only set of data distributed over a cluster of machines, which is called a resilient distributed dataset (RDD).

RDDs were developed due to limitations in MapReduce computing, which read data from disk by reducing the results into a map. RDDs work faster on a working set of data which is stored in memory which is ideal for real-time processing and analytics. When Spark processes data, the least-recent data is evicted from RAM to keep the memory footprint manageable since disk access can be expensive.

What Is Apache Hadoop?

Hadoop is a data-processing technology that uses a network of computers to solve large data computation via the MapReduce programming model.

Compared to Spark, Hadoop is a slightly older technology. Hadoop is also fault tolerant. It knows hardware failures can and will happen and adjusts accordingly. Hadoop splits the data across the cluster and each node in the cluster processes the data in parallel very similar to divide-and-conquer problem solving.

For managing and provisioning Hadoop clusters, the top two orchestration tools are Apache Ambari and Cloudera Manager. Most comparisons of Ambari vs. Cloudera Manager come down to the pros and cons of using open source or proprietary software.

Apache Spark vs. Hadoop at a Glance

The main difference between Apache Spark vs. Hadoop is that Spark is a real-time data analyzer, whereas Hadoop is a processing engine for very large data sets that do not fit in memory.

Hadoop can handle batching of sizable data proficiently, whereas Spark processes data in real-time such as streaming feeds from Facebook and Twitter/X. Spark has an interactive mode allowing the user more control during job runs. Spark is the faster option for ingesting real-time data, including unstructured data streams.

Hadoop is optimal for running analytics using SQL because of Hive, a data warehouse system that is built on top of Hadoop. Hive integrates with Hadoop by providing an SQL-like interface to query structured and unstructured data across a Hadoop cluster by abstracting away the complexity that would otherwise be required to write a Hadoop job to query the same dataset. Spark also has a similar interface, Spark SQL, which is part of the distribution and does not have to be added later.

Spark vs. Hadoop: Key Differences

In this section, let’s compare the two technologies in a little more depth.

Ecosystem

The core computation engines of Hadoop and Spark differ in the way they process data. Hadoop uses a MapReduce paradigm that has a map phase to filter and sort data and a reduce phase for aggregating and summarizing data. MapReduce is disk-based, whereas Spark uses in-memory processing of Resilient Distributed Datasets (RDDs), which is great for iterative algorithms such as machine learning and graph processing.

Hadoop comes with its own distributed storage system, the Hadoop Distributed File System (HDFS), which is designed for storing large files across a cluster of machines. Spark can use Hadoop’s HDFS as its primary storage system, but it also supports other storage systems like S3, Azure Blob Storage, Google Cloud Storage, Cassandra, and HBase.

Hadoop and Spark include various data processing APIs for different use cases. Spark Core provides functionality for Spark jobs like task scheduling, fault tolerance, and memory management. Spark SQL allows SQL-like queries on large datasets and integrates well with structured data. It supports querying both structured and semi-structured data. The Spark Streaming component provides real-time stream processing by dividing data streams into small batches. MLlib and GraphX are libraries for machine learning algorithms and graph processing, respectively, that run on Spark.

Hadoop includes MapReduce, which is the core API for data processing in Hadoop.  The following tools can be added to Hadoop for data processing:

• Apache Hive is a data warehouse system built on top of Hadoop for querying and managing large datasets using a SQL-like language.

• Apache HBase is a distributed NoSQL database that runs on top of HDFS and is used for real-time access to large datasets.

• Apache Pig is a platform for analyzing large datasets that uses a scripting language (Pig Latin) to express data transformations.

For cluster management, YARN (Yet Another Resource Manager) is the most common approach to run Spark applications to run transparently in tandem with Hadoop jobs in the same cluster which provides resource isolation, scalability, and centralized management.

Spark does have a few more cluster management configurations than Hadoop.  Apache Mesos is a distributed systems kernel that can run Spark, and Spark also has native support for Kubernetes, which can be used for containerized deployment and scaling capabilities in Spark clusters.

For fault tolerance, Hadoop has data block replication that ensures data accessibility if a node fails, and Spark uses RDDs to reconstruct data in the event of failure.

Real-time processing and machine learning are both included with Spark. Spark Streaming natively supports real-time data processing with low latency, but Hadoop requires tools like Apache Storm or Apache Flink to accomplish this task. MLLib is Spark’s machine learning library, and Apache Mahout can be used with Hadoop for machine learning.

Features

Hadoop has its own distributed file system, cluster manager, and data processing. In addition, it provides resource allocation and job scheduling as well as fault tolerance, flexibility, and ease of use.

Spark includes libraries for performing sophisticated analytics related to machine learning, AI, and a graphing engine. The scheduling implementation between Hadoop and Spark also differs. Spark provides a graphical view of where a job is currently running, has a more intuitive job scheduler, and includes a history server, which is a web interface to view job runs.

Performance and Cost Comparison

Hadoop accesses the disk frequently when processing data with MapReduce, which can yield a slower job run. In fact, Spark has been benchmarked to be up to 100 times faster than Hadoop for certain workloads.

However, because Spark does not access to disk as much, it relies on data being stored in memory. Consequently, this makes Spark more expensive due to memory requirements. Another factor that makes Hadoop more cost-effective is its scalability; Hadoop mixes nodes of varying specifications (e.g. CPU, RAM, and disk) to process a data set. Cheaper commodity hardware can be used with Hadoop.

Other Considerations

Hadoop requires additional tools for Machine Learning and streaming which come included in Spark. Hadoop can also be very complex to use with its low-level APIs, while Spark abstracts away these details using high-level operators. Spark is generally considered to be more developer-friendly and easy to use.

Spark Use Cases

Spark is great for processing real-time, unstructured data from various sources such as IoT, sensors, or financial systems and using that for analytics. The analytics can be used to target groups for campaigns or machine learning. Spark has support for multiple languages like Java, Python, Scala, and R, which is helpful if a team already has experience in these languages.

Hadoop Use Cases

Hadoop is great for parallel processing of diverse sets of large amounts of data. There is no limit to the type and amount of data that can be stored in a Hadoop cluster. Additional data nodes can be added to address this requirement. It also integrates well with analytic tools like Apache Mahout, R, Python, MongoDB, HBase, and Pentaho.

It’s also worth noting that Hadoop is the foundation of Cloudera’s data platform, but organizations that want to go 100% open source with their Big Data management and have a little more control over where they host their data should consider the Hadoop Service Bundle as an alternative.

Using Hadoop and Spark Together

Using Hadoop and Spark together is a great way to build a powerful, flexible big data architecture. Typical use cases are large-scale ETL pipelines, data lakes and analytics, and machine learning. Hadoop’s scalable storage via HDFS can be used for storing large datasets and Spark can perform distributed data processing and analytics. Hadoop jobs can be used for large and long-running batch processes, and Spark can read data from HDFS and perform complex transformations, machine learning, or interactive SQL queries. Spark jobs can run on top of a Hadoop cluster using Hadoop YARN as the resource manager. This leverages both Hadoop’s storage and Spark’s faster processing, combining the strengths of both technologies.

Final Thoughts

Organizations today have more data at their disposal than ever before, and both Hadoop and Spark have a solid future in the realm of open source Big Data infrastructure. Spark has a vibrant and active community including 2,000 developers from thousands of companies which include 80% of the Fortune 500.

For those thinking that Spark will replace Hadoop, it won’t. In fact, Hadoop adoption is increasing, especially in banking, entertainment, communication, healthcare, education, and government. It’s clear that there’s enough room for both to thrive, and plenty of use cases to go around for both of these open source technologies.

Editor’s Note: This blog was originally published in 2021 and was updated and expanded in 2025. 

It’s a new year, which is a good time to reflect on what changed in the never-boring OSS world over the past 12 months — and what 2025 might bring. Read on to see what I expect we’ll be hearing and reading about this year in terms of open source trends.

Demand for More Data Sovereignty

More and more organizations are streaming and processing large data sets in realtime, for reasons ranging from observability into manufacturing processes and sentiment analysis of social media, to routing and processing financial transactions and training Large Language Models for AI applications.

Big Data technologies are complex, often requiring both specialized IT operations teams as well as infrastructure architects. As a result, many companies have turned to managed solutions in order to offload this work so their own teams can focus on the data and data analysis itself. However, many of these managed solutions have started adding non-optional features, requiring public cloud deployment, and dramatically increasing their pricing structure, often without transparency to their customers. Additionally, customers are running into compliance issues, as new regulatory requirements mandating how and where data is processed and stored are sometimes incompatible with these platforms.

Since many of these solutions are based on existing OSS technologies such as Hadoop, Kafka, and others, we expect to see companies rethinking their Big Data strategy, looking for ways to achieve data sovereignty by bringing their Big Data solutions in-house with open source software, and partnering with commercial support vendors as needed to aid in architecture and management.

The Search for the Next CentOS Continues

On June 30, 2024, we saw a milestone in the Enterprise Linux ecosystem as CentOS 7 reached end of life. While a number of commercial offerings emerged to allow CentOS users to postpone their migrations, these are short-term solutions, and eventually companies will need to migrate to new distributions.

As CentOS was itself a 1-to-1 replacement for Red Hat Enterprise Linux (RHEL), this of course remains an option. However, this ignores one of the main reasons for using CentOS: the fact that you could use it without support contracts, or contract with third parties for support, often at steep discounts over Red Hat.

Several CentOS alternatives have emerged in the past few years, including AlmaLinux and Rocky Linux, providing essentially the same 1:1 OSS counterpart to RHEL that CentOS provided. Like CentOS, these distros are community-supported, and both are relatively new, with an unproven track record of support that makes some enterprise organizations nervous.

Additionally, many businesses have become increasingly security-minded in the last few years, due to a variety of CVE announcements against OSS software as well as supply chain attacks. A freely available Linux distribution is often not enough for these companies; they also need a secure baseline image to start from in order to streamline the security measures they need to take to protect their software. While commercial solutions such as RHEL, Oracle Linux, and SUSE Linux provide these, they come at substantial cost.

All of which is to say, there is still no clear victor in the so-called “Linux Wars” but as more companies migrate off CentOS in 2025, we’ll probably have a better sense of whether security or cost-effectiveness is the bigger driver based on where they end up.

Open Source AI Enters the Next Phase

AI has become the technology du jour, replacing previously trending topics such as the metaverse and cryptography. Technically speaking, most of the technology around AI today is around Large Language Models (LLMs) and Generative AI, which use statistical models in order to determine what to do next, whether that’s completing a conversational prompt, splicing together images, or other use cases.

Generative AI models require large amounts of training, with large amounts of data — which means that it falls under the umbrella of Big Data when it comes to open source. The need to keep these processes and technologies secure and performant is paramount — and just like with Big Data, the amount of expertise is spread thin.

AI is a hugely competitive market and that’s not going to change in 2025. There are a variety of toolchains already available for training LLMs and other models within Big Data pipelines, with tools such as Apache Spark, Apache Kafka, and Apache Cassandra providing key functionality used to train these models. I anticipate seeing more companies developing bespoke LLMs that directly support the products they produce, and they will use open source toolchains to do this.

Lessons From the XZ Utils Backdoor

In 2024, the security world was rocked by the discovery of a malicious backdoor in the xz utility, and attention was turned to staving off future supply chain attacks.

Supply chain attacks? But isn’t xz an open source utility?

In this particular case, an individual had used social engineering to very gradually, over multiple years, take over maintenance of the open source project producing xz. Once they had, they slipstreamed in the backdoor in a release they signed.

While many tried to decry this incident as evidence that open source software is inherently insecure (as this sort of social engineering is always a possibility), there’s another side to the coin: it was an open source packager performing standard benchmarking on a development release of an operating system who uncovered the issue. As the adage goes, many eyeballs make all bugs shallow.

One side effect of this attack was renewed interest in Software Bills of Materials (SBOMs). Organizations that are able to produce an SBOM for their software have a record of what they have installed, including the specific versions, as well as what licenses apply. This provides the ability to audit your software — or your vendor’s software — for known security vulnerabilities, and to react to them more quickly. Many organizations are forming DevSecOps teams to manage building, maintaining, and validating SBOMs against vulnerability lists as part of ongoing security in-depth efforts.

Even better, the OSS community is stepping up to build tooling for producing SBOMs into their development chains and utilities. The Node.js community has several projects that will produce SBOMs from application manifests; PHP’s Composer project added these capabilities; Java’s Maven and Gradle each have plugins to generate SBOMs.

Security is and will continue to be a top concern for companies using open source software, and in 2024, we saw proof that the ecosystem is helping protect them. Whether or not we will have another zero-day attack in 2025 remains to be seen, but companies are recognizing the benefit of being more proactive by embedding security best practices into their development and operations workflows and managing OSS inventory with the assistance of tools like SBOMs.

Explore solutions 

It’s no secret that data collection has become an integral part of our everyday lives; we leave a trail of data everywhere we go, online and in person. Companies that collect and store huge volumes of data, otherwise known as Big Data, need to be strategic about how that data is handled at every step. With a better understanding of Big Data management and its role in strategic planning, organizations can streamline their operations and leverage their data analytics to optimize business outcomes. 

In this blog, our expert discusses some of the components of Big Data management strategy and explores the key decisions enterprises must make to find long-term success in the Big Data space. 

Why Strategic Big Data Management Matters

When Big Data technologies are effectively incorporated into an organization’s strategic planning, leaders can make data-driven decisions with a greater sense of confidence. In fact, there are numerous ways in which Big Data and business intelligence can go hand in hand.

One example of this is strategic pricing. With the insights gained from using data analysis techniques, it is possible to optimize pricing on products and services in a way that maximizes profits. This type of strategizing can be especially effective when Big Data solutions look closely at metrics such as competitor pricing, market demand trends, and customer buying habits or customer data analysis.

Big Data can play a key role in product development. Through the analysis of industry trends and customer behavior, businesses can determine exactly what consumers are looking for in a particular product or service. They can also narrow down pain points that may inhibit customers from purchasing, make changes to alleviate them, and put out better products as a result.

Understanding Big Data Management

Big Data refers to the enormous amounts of data that is collected in both structured and unstructured ways. The sheer size and amount of this data makes it impossible to process and analyze using “traditional” methods (i.e. databases). 

Instead, more advanced solutions and tools are required to handle the three Vs of Big Data: Data containing great variety, coming in increasing volumes, at high velocity. This data typically comes from public sources like websites, social media, the cloud, mobile apps, sensors, and other devices. Businesses access this data to see consumer details like purchase history and search history, to better understand likes, interests, and so on. 

Big Data analytics uses analytic techniques to examine data and uncover hidden patterns, correlations, market trends, and consumer preferences. These analytics help organizations make informed business decisions that lead to efficient operations, happy consumers, and increased profits.

Developing a Big Data Management Strategy

If you are planning to implement a Big Data platform, it’s important to first assess a few things that will be key to your Big Data management strategy.

Determine Your Specific Business Needs

The first step is determining what kind of data you’re looking to collect and analyze. 

• Are you looking to track customer behavior on your website?
• Analyze social media sentiment?
• Understand your supply chain better? 

It’s important to have a clear understanding of what you want to achieve before moving forward with a Big Data solution.

Consider the Scale of Your Data

The sheer amount of your data will play a big role in determining the right Big Data platform for your organization. Some questions to ask include:

• Will you need to store and process large amounts of data, or will a smaller solution be sufficient?
• Do you have a lot of streaming data and data in motion? 

If you’re dealing with large amounts of data, you’ll need a platform that can handle the storage and processing demands. 

Hadoop and Spark are popular options for large-scale data processing. However, if your data needs are more modest, a smaller solution may be more appropriate.

Assess Your Current Infrastructure

Before implementing a Big Data platform, it’s important to take a look at your current infrastructure. For example, do you have the necessary hardware and software in place to support a Big Data platform? Are there any limitations or constraints that need to be taken into account? What type of legacy systems are you using and what are their constraints?

It’s much easier to address these issues upfront before beginning the implementation process. It’s also important to evaluate the different options and choose the one that best fits your business needs both now and in the future.

Implementing a Big Data platform requires a high level of technical expertise. It’s important to assess your in-house technical capabilities before putting a solution in place.

If you don’t have the necessary skills and resources, you may need to consider bringing in outside help, outsourcing the implementation process, or hiring for the skill sets necessary.

Big Data Hosting Considerations

Where to host Big Data is the subject of ongoing debate. In this section, we’ll dive into the factors that IT leaders should weigh as they determine whether to host their Big Data infrastructure on-premises (“on-prem”) vs. in the cloud.

Keeping Big Data infrastructure on-prem has historically been a comfortable option for teams that need to support Big Data applications. However, businesses should consider both the benefits and drawbacks of this scenario. 

Benefits of On-Prem

• More Control: On-premises gives IT teams more control over their physical hardware infrastructure, enabling them to choose the hardware they prefer and to customize the configurations of that hardware and software to meet unique requirements or achieve specific business goals.
• Greater Security: By owning and operating their own dedicated servers, IT teams can apply their own security protocols to protect sensitive data for better peace of mind.
• Better Performance: The localization of hosting on-premises often reduces latency that can happen with cloud services, which improves data processing speeds and response times.
• Lower Long-Term Costs: While on-premises is a more costly option to buy and build upfront, it has better long-term value as a business scales up and uses the full resources of this investment.
• More  Uptime: Many IT teams prefer to be able to monitor and manage their server operations directly so they can resolve issues quickly, resulting in less downtime. 

Is It Time to Open Source Your Big Data Management?

Giving a third party complete control of your Big Data stack puts you at risk for vendor lock-in, unpredictable expenses, and in some cases, being forced to the public cloud. Watch this on-demand webinar to learn how OpenLogic can help you keep costs low and your data on-prem.

 

Drawbacks of On-Prem

• Higher Upfront Costs: As noted above, on-prem can be cost-effective at a larger scale or in the long-run, but the initial cost to buy and build the infrastructure can be restrictive to businesses that do not have budget to invest at the outset of their services.
• Staffing Constraints: To deploy an effective on-premises solution, an IT team that is qualified to both build and manage the infrastructure is necessary. If a business has critical services, this may require payroll for 24/7 staffing and the on-going expense of training and certifications to maintain the proper IT team skills.
• Data Center Challenges: On-premises also requires an adequate location to host the infrastructure. The common practice of racking up servers in ordinary closet spaces brings significant risks to security and reliability, not to mention adherence to proper safety guidelines or compliance requirements. Additionally, if the location uses conventional energy, the cost to operate power-hungry high-availability hardware can be significant.
• Longer Time to Deploy: Even with the right skills and resources, an on-premises solution can take weeks or months to actually build and spin up for production.
• Limited Scalability: On-premises gives IT teams the ability to quickly scale within their existing hardware resources. But when capacity begins to run out, they will need to procure and install additional infrastructure resources, which is not always easy, quick, or inexpensive.

As per the cloud options, the most conventional approach is for IT teams to partner with vendors that offer a broad portfolio of services to support Big Data applications, which alleviates the burdens of hardware ownership and management. 

While a popular decision, businesses again would be wise to consider both the pros and cons of public cloud-based Big Data platforms.

Pros of Public Cloud

• Rapid Deployment: Public clouds allow businesses to purchase and deploy their hosting infrastructure quickly. Self-service portals also enable rapid deployment of infrastructure resources on-demand.
• Easy Scalability: Public clouds offer nearly unlimited scalability, on-demand. Without any dependency on physical hardware, businesses can spin storage and other resources up (or down) as needed without any upfront capital expenditures (CapEx) or delays in time to build.
• OpEx Focused: Public clouds charge users for the cloud services they use. It is a pure operating expense (OpEx). As a result, public cloud OpEx costs may be higher than the OpEx costs of an on-prem or private cloud environment. However, as discussed previously, public clouds do not require the traditionally upfront CapEx costs of building that on-prem or private cloud environment.
• Flexible Pricing Models: Public clouds also give businesses the ability to use clouds as much or little as they like, including pay-as-you-go options or committed term agreements for higher discounts.

Cons of Public Cloud 

• More Security Risks: The popularity of public cloud platforms has enabled a wide variety of available security applications and service providers. Nevertheless, public clouds are still shared environments.As increasing processes are requested at faster speeds, data can fall outside of standard controls. This can create unmanaged and ungoverned “shadow” data that creates security risks and potential compliance liabilities.
• Less Control: In a shared environment, IT teams have limited to no access to modify and/or customize the underlying cloud infrastructure. This forces IT teams to use general cloud bundles to support unique needs. To get the resources they do need, IT teams wind up paying for bundles that include resources they do not need, leading to cloud waste and unnecessary expenses.
• Uptime and Reliability: For Big Data to yield useful insights, public clouds need to operate online uninterrupted. Yet it is not uncommon for public clouds to experience significant outages.
• Long-Term Costs: Public clouds are a good option for new business start-ups or services that require limited cloud resources. But as businesses scale up to meet demand, public clouds often become a more expensive option than on-prem or private cloud options. And, because of the complexity of public cloud billing, it can be very difficult for businesses to understand, manage, and predict their data management costs.

Overall, decisions on how and where to implement a comprehensive Big Data solution should be made with a long-term perspective that accounts for costs, resources alignment, and scalability goals.

Big Data Management Considerations

On the surface, it seems ideal to keep all your business functions in-house, including the ones related to Big Data implementations. In reality, however, it is not always an option, especially for companies that are scaling quickly, but lack the expertise and skills to manage projects of the complexity and depth that Big Data practices demand.

In this section, we will explore what organizations stand to lose or gain by outsourcing expertise when it comes to their Big Data management and maintenance.

Benefits of Outsourcing Big Data Management

• Access to Advanced Skills and Technologies: Outsourcing the management of Big Data implementations allows businesses to tap into a pool of specialized skills and cutting-edge technologies without the overhead of developing these capabilities in-house. As technology rapidly evolves, third party partners must stay ahead by investing in the latest tools and training for their teams. So they absorb that cost, instead of their customers.
• Reducing Operational Costs: As counterintuitive as it may sound, working with specialized experts in the field, who have successfully implemented Big Data infrastructures multiple times, can lead to significant cost-savings in the long run. And when it comes to Big Data strategy, thinking about the sustainability and long-term viability of solutions is critical when embarking on projects of this magnitude.
• Faster Time to Market:Outsourced teams are designed to be agile and flexible. The right ones have the wealth of knowledge necessary to get the work done as fast as possible, bringing your Big Data projects to market in months rather than years.
• Reduced Risk: By choosing a Big Data partner well-versed in Big Data practices, including security at all levels, you can reduce the inherent risks associated with Big Data projects.

Challenges of Outsourcing Big Data Management

• Cultural and Communication Gaps: Outsourcing management and support can mean working with teams from different cultures that are located in different time zones, which can cause communication issues and misunderstandings. To solve these problems, companies can set up clear ways to communicate, arrange meetings when both teams are available, and train everyone to understand each other’s cultures better. This helps everyone work together more effectively and efficiently.
• Data Security Risks: Outsourcing Big Data implementations poses some risks to data security. When third parties handle sensitive data, there is always the possibility of exposure to threats such as unauthorized access, data theft, and leaks.To prevent such outcomes, it is crucial to maintain high-security standards, restrict data access to qualified personnel, and avoid sharing sensitive information via unsecured channels. (And of course, do some vetting and choose a partner with a solid reputation!)
• Dependency and Loss of Control: Relying too much on an external partner can lead to dependence and a loss of control over how data is managed. Good third-party partners will not gate-keep knowledge and will work to help teams understand what is happening in their Big Data infrastructure so they can make informed decisions about how the data is handled.

Final Thoughts

Implementing and supporting a Big Data infrastructure can be challenging for internal teams. Big Data technologies are constantly evolving, making it hard to keep pace. Additionally, storage and mining systems are not always well-designed or easy to manage, which is why it is best to stick with traditional architectures and make sure that clear documentation is provided. This makes the data collection process simpler and more manageable for whomever is overseeing it. 

When it comes to Big Data management, there is no “one size fits all” solution. It’s important to explore your options and consider hybrid approaches that give you data sovereignty and a high degree of control but also allow you to lean on the expertise of a third partner when necessary.
