The increasing use of SD-WAN for connecting enterprise networks improves productivity, reduces cost, and increases application performance.\u00a0\u00a0<\/p>\n<p>It is a feature-packed technology that centralizes security, management, networking, and more. Consequently, organizations with cloud solutions view SD-WAN as an infrastructure upgrade to operations.\u00a0<\/p>\n\n<h3>Wrong Approaches<\/h3>\n\n<p>A frequent occurrence with businesses is the focus on individual technical elements. Unfortunately, many such enterprises fail to realize \u00a0the need to address end-to-end solutions.\u00a0<\/p>\n<p>Selection should encompass all available approaches with the choice that best suits the company\u2019s needs, budget, and savviness. Another aspect to \u00a0consider is the fact that IT teams often fixate on price. Unfortunately, most of them misinterpret prices, opting for cheaper options resulting in \u00a0poor network performance .\u00a0\u00a0<\/p>\n<p>Such 0rganizations often soon encounter issues with high latency, prolonged downtimes, less supportive service-level agreements, and more. As enticing as cost savings can appear, ensure it never poses serious risk to your network connectivity or SD-WAN designs.\u00a0<\/p>\n\n<h3>Responding to this Challenge:<\/h3>\n<ul>\n \t<li>Ensure that all choices and approaches produce maximum results for the company\u2019s network.\u00a0<\/li>\n \t<li>Consider platforms with built-in cloud and security vendor access for appliances.\u00a0<\/li>\n \t<li>Ensure to prioritize necessary performance features over novel ones.\u00a0<\/li>\n \t<li>Technology evolves at a rapid pace, so plan accordingly with future long-term growth in mind.<\/li>\n<\/ul>\n<h3>Overlooking the Quality of Service (QoS) Concept for SD-WAN<\/h3>\n\n<p>One attribute that should never get overlooked is the QoS. An equally important aspect is the quality of experience. However, SD-WAN service providers never seem to offer end-to-end prioritization. Although it provides an efficient traffic segmentation and path selection, traffic movement often gets delayed. Therefore, seeking an SD-WAN approach with \u2018fail safe\u2019 technology features is crucial.\u00a0<\/p>\n<p>These options must offer superior performance to MPLS across all applications. MPLS itself comes with end-to-end QoS via six settings for service-level categories, though also with delayed traffic movement.\u00a0\u00a0<\/p>\n\n<h3>Responding to this Challenge:<\/h3>\n<ul>\n \t<li>Never compromise on the quality of service and quality of experience with network connectivity.\u00a0\u00a0<\/li>\n \t<li>Be sure to purchase local site-by-site internet underlay with low-cost service that provides high QoS and QoE along with various available features.Consult with experts to get the best-customized recommendations.\u00a0<\/li>\n<\/ul>\n<h3>SD-WAN Security Requirements<\/h3>\n\n<p>Some SD-WAN technology lacks security capabilities. Unfortunately, these security lapses often open the door to cyber threats.\u00a0<\/p>\n<p>\u00a0For instance, there\u2019s usually an edge security change with SD-WAN features such as virtual private network (VPN) deployment. In other scenarios, data get transferred with every migration to cloud solutions. Therefore, deploying hardware and virtualized instances with accessed security policies still comes with risks.\u00a0<\/p>\n<h3><strong>\u00a0Responding to this Challenge\u00a0<\/strong><\/h3>\n<ul>\n \t<li>Organizations should take time to research all vendor claims and ensure all security functions meet \u00a0company criteria.\u00a0<\/li>\n \t<li>Strategize the integration of cyber security and networking solutions instead of separating the two.\u00a0<\/li>\n \t<li>Make it a habit to add new layers of security systems where and when necessary.\u00a0<\/li>\n \t<li>Try integrating existing security with SD-WAN solutions.\u00a0<\/li>\n<\/ul>\n<h3>SD-WAN Management Issues<\/h3>\n\n<p>Today\u2019s SD-WAN solutions help to blur the lines between DIY and the type of management structure in place. Organizations never get to pick the management level traditionally. One of the drawbacks of the SD-WAN model is that it breaks most businesses\u2019 existing centralized security inspections.\u00a0\u00a0<\/p>\n<p>Organizations often build hub network architectures designed around the consolidation of data streams. The idea is to backhaul traffic through a centralized channel into data centers. Firewalls are used to create \u00a0single security inspection points \u00a0so that packets get examined before making it into the data center. The presence of an SD-WAN architecture makes this method ineffective.\u00a0<\/p>\n<p>By default, SD-WAN solutions lack integrated security that allows routing all traffic through a full security stack for inspection. There\u2019s also the task of threat prevention before proceeding to its destination.\u00a0<\/p>\n<p>\u00a0With SD-WAN, \u00a0lots of traffic moves outside the data center perimeter. As such, connections to the cloud from external sources like remote workers never go through the traditional inspection process.\u00a0<\/p>\n<p>The outcome for organizations is a forced decision. They have the choice of forgoing the benefits of SD-WAN by backhauling traffic to the data center for inspection, or simply not securing traffic on the WAN at all.\u00a0<\/p>\n<h3>Responding to this Challenge:<\/h3>\n<ul>\n \t<li >Give the required training to the IT team and staff members\u00a0\u00a0<\/li>\n \t<li data-leveltext=\"\uf0b7\" >Get dedicated staff that can oversee the end-to-end SD-WAN implementation\u00a0<\/li>\n \t<li>Infuse post-implementation monitoring and management into the company\u2019s activity.\u00a0<\/li>\n<\/ul>\n<h3>Cloud Connectivity Requirements<\/h3>\n<p>When it comes to selecting SD-WAN projects, vendors and the IT team require cloud connectivity to either AWS, Google, or Microsoft Azure. Therefore, SD-WAN vendors typically belong to one of three categories based on their cloud access capabilities.\u00a0<\/p>\n<ul>\n \t<li><b>Native Cloud Access:\u00a0<\/b>This category includes built-in access to the vendor\u2019s SD-WAN architecture . It involves using the cloud\u2019s backbone infrastructure for connecting to branch office sites. For vendors that adopt the cloud as a global backbone, this is an everyday occurrence. However, this option is better for connecting to \u00a0local cloud data centers since the deployment of cloud gateway architecture is a unique system.\u00a0<\/li>\n \t<li><b>Vendor Access Provision:\u00a0<\/b>This category entails vendors delivering SD-WAN appliances to a cloud environment through public gateways or private backbones. Such an option comes with more flexibility regarding \u00a0vendor features. Public gateways and private backbones route traffic more efficiently than the Internet.\u00a0<\/li>\n \t<li>\u00a0<b>Customer Access Provision:\u00a0<\/b>Here the customer is responsible for deploying the appliances in the local cloud-based data center with this option. This option offers cloud access in a more ad hoc and \u00a0simplified architecture.\u00a0<\/li>\n<\/ul>\n<h3>Responding to this Challenge:<\/h3>\n<ul>\n \t<li >Normalize analyzing deployment needs and internal application performance.\u00a0<\/li>\n \t<li>After implementation, monitor application performance. It ensures that the business takes timely actions and prevents any form of disruption.\u00a0<\/li>\n \t<li>It\u2019s crucial to decide the bandwidth requirements and latency policies in a multi-cloud environment. An excellent way to achieve this is by evaluating service dependency on several micro-service segments.<\/li>\n<\/ul>\n<p>\nThese shortcomings aside, SD-WAN offers numerous benefits for organizations \u00a0looking to optimize and transform their corporate networks.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2004c86 elementor-widget elementor-widget-shortcode\" data-id=\"2004c86\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"shortcode.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-shortcode\">\t\t<div data-elementor-type=\"page\" data-elementor-id=\"18103\" class=\"elementor elementor-18103\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-748947f elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"748947f\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[{&quot;jet_parallax_layout_image&quot;:{&quot;url&quot;:&quot;&quot;,&quot;id&quot;:&quot;&quot;,&quot;size&quot;:&quot;&quot;},&quot;_id&quot;:&quot;c4f773e&quot;,&quot;jet_parallax_layout_image_tablet&quot;:{&quot;url&quot;:&quot;&quot;,&quot;id&quot;:&quot;&quot;,&quot;size&quot;:&quot;&quot;},&quot;jet_parallax_layout_image_mobile&quot;:{&quot;url&quot;:&quot;&quot;,&quot;id&quot;:&quot;&quot;,&quot;size&quot;:&quot;&quot;},&quot;jet_parallax_layout_speed&quot;:{&quot;unit&quot;:&quot;%&quot;,&quot;size&quot;:50,&quot;sizes&quot;:[]},&quot;jet_parallax_layout_type&quot;:&quot;scroll&quot;,&quot;jet_parallax_layout_direction&quot;:&quot;1&quot;,&quot;jet_parallax_layout_fx_direction&quot;:null,&quot;jet_parallax_layout_z_index&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_x&quot;:50,&quot;jet_parallax_layout_bg_x_tablet&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_x_mobile&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_y&quot;:50,&quot;jet_parallax_layout_bg_y_tablet&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_y_mobile&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_size&quot;:&quot;auto&quot;,&quot;jet_parallax_layout_bg_size_tablet&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_size_mobile&quot;:&quot;&quot;,&quot;jet_parallax_layout_animation_prop&quot;:&quot;transform&quot;,&quot;jet_parallax_layout_on&quot;:[&quot;desktop&quot;,&quot;tablet&quot;]}]}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-7995c19\" data-id=\"7995c19\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-a437045 elementor-widget elementor-widget-image-box\" data-id=\"a437045\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image-box.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-image-box-wrapper\"><div class=\"elementor-image-box-content\"><h3 class=\"elementor-image-box-title\">About Version 2 Digital<\/h3><p class=\"elementor-image-box-description\">Version 2 Digital is one of the most dynamic IT companies in Asia.
