The WAN is flooded with vendors who offer digital transformation. IT decision-makers have to sift marketing material in order find a partner that is right for their organization.

Partnering with a global SD-WAN provider is often the best option for companies that have international offices. They can offer access to consultants and professional installation services, as well as 24/7 support.

Flexible WAN connectivity

Contrary to traditional networking box solutions that assemble point hardware products from different vendors, SD-WAN intelligently optimizes traffic across various forms of WAN transport and application. This ensures high-quality applications even when underlay transport services become impaired - for instance if an MPLS link goes down or underperforms, basic SD-WAN solutions might divert it to the internet where packet loss, latency, and jitter are common - leading to inconsistent Quality of Experience across connections. SD-WAN solutions that are business-driven can solve these problems and deliver consistent performance across a range of network conditions.

Business-driven SD WAN can support multicloud initiatives, by providing direct access to public and enterprise clouds. This allows for users to access cloud/SaaS-based applications securely from remote areas over an encryption connection. It also optimizes the performance of vital apps over any type of WAN, and offers robust security features like threat analytics and edge security policies.

Businesses that are using global SDWANs have the ability to easily add new locations or change existing ones without having to compromise on security, performance, or reliability. SD-WANs offer cloud and Internet access via a single policy and connect directly to the enterprise datacenters using a secured backbone.

Reduced Costs

SD-WANs offer a wide range of benefits, depending upon their application. This includes lower connectivity costs due to the elimination of expensive MPLS lines in favor commodity broadband connections using fiber, DSL or cable. The centralization of policy management will reduce the need for individual router configurations and also lower the costs associated with upgrades and equipment updates.

SD-WAN architecture facilitates multicloud connectivity as well by providing direct links to the leading IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software-as-a-Service) providers, prioritizing them and speeding up their services for business-critical apps. Additionally, the built-in resiliency ensures that users won't be impacted if one of their connections goes down.

SD-WAN is deployable using three main strategies, including Internet-based SD-WAN, Telco/MSP Managed Services and on-premises OTT vCPE. Which of these options best meet the performance needs of your users and applications depends on your team's skillset and your willingness to undertake new projects internally. Hybrid deployments, which combine SD-WAN capabilities with WAN optimization or firewall capabilities, may also work.

Secure Connectivity

SD-WANs that are business-driven centralize functions, provide greater visibility, and connect directly to SaaS- and IaaS-cloud applications using local internet breakouts, not VPNs. This improves app performance, user experiences, and productivity.

Legacy solutions can offer a certain level of security. But their inability for reliable and high-performance connectivity for vital business applications and services could be a huge obstacle for businesses who have multiple branch offices or global users.

SD-WANs differ from traditional routers in that they automate and simplify the WAN management. This makes networking professionals' jobs easier by optimizing connectivity faster for users and applications. It solves many problems with traditional WANs such as the long lead time for new connections, or hub-and spoke architectures that do not support agile apps or hybrid workforce models.

SD-WANs of the next generation offer solutions for these and other issues by combining routing, security, and optimization into a single integrated platform, which can be deployed on cloud. This platform, commonly referred to as an SASE (Secure Access Service Edge), connects business sites to their private network as well as public internet, providing reliability and cost effectiveness while offering seamless user experiences.

Global Scalability

SD-WAN allows you to extend your enterprise network to the cloud, and connect to services directly. It also provides intelligent application steering for mission-critical applications across multiple connections.

As opposed to MPLS, which requires complex configuration and maintenance at every branch office in order to guarantee performance, SD-WAN enables your branches and remote offices to connect to critical business applications over cost-effective broadband and commercial Internet links, which allow you to reduce costs while giving users access to tools they need for productivity wherever they may be located.

SD-WAN can be managed by multiple service providers. GCX has four options, depending on your organization's needs: proactive and reactive underlay; fully managed overlay; or a self-managed solution using uCPEs.

GCX's SD-WAN fully managed solution allows you to eliminate the need for multiple vendors and their hardware, as well as issues with deployment and support that can be associated with DIY SD WAN. By choosing GCX’s fully-managed service, customers can take advantage of global SLAs with carrier relationships providing 24/7 support. They also get engineers specialized on WAN connectivity technologies and NFV/SDN. GCX engineers will be able to identify any issues that may arise with your SD-WAN overlay or underlay circuits.
