There are many vendors on the WAN market offering digital transformation. IT decision makers must sort through marketing material to find the right partner for their company.
Partners offering global SD-WAN are often the best solution for organizations with international sites, offering access to consultants, professional installation services and 24/7 support services.
Flexible WAN connectivity SD-WAN is a superior solution to traditional networking boxes, which assemble different point hardware products. SDWAN intelligently optimizes all traffic between WAN transport and applications. SD-WAN ensures that applications are delivered with high quality even when the transport service is impaired. For example, if an MPLS connection goes down or performs poorly, SD-WAN may divert traffic to the internet, where packet loss and jitter can be common. SD-WANs designed for business solve these issues by delivering consistent application performance regardless of the network conditions.
Business-driven SD WANs can support multi-cloud initiatives as well by offering direct connectivity to both public and enterprise cloud services out of the box. This allows users accessing cloud/SaaS application from remote locations securely over an encrypted link, optimizing the performance of critical apps on any WAN connection while offering robust features such as security analytics and granular policies at the edge.
Businesses that use global SD-WANs are able to add or change locations easily without compromising on reliability, security or performance. 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. Additionally, centralizing the policy management reduces individual router programming and lowers costs for upgrades and equipment refresh.
SD-WAN architecture also facilitates multi-cloud connectivity by offering direct links to leading IaaS, PaaS and SaaS providers and prioritizing and speeding them for business critical apps. Furthermore, its built-in resilience ensures that even if one connection goes down users won't lose access.
SD-WANs can be deployed in three different ways: Internet based, Telco or MSP managed service and OTT vCPE installed on premises. 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. Alternatively, hybrid deployments that combine SD-WAN with WAN optimization and firewall capabilities may also be suitable.
Secure Connectivity SD-WANs designed for businesses centralize network operations and offer greater transparency. They provide secure direct connectivity via local internet break-out (not VPN) to SaaS/IaaS applications in the cloud, improving app performance and user-experience, while simultaneously lowering installation costs by leveraging broadband, 4G, or LTE connections as a supplement to MPLS links.
Legacy solutions are secure, but they can't provide high-performance and reliable connections to vital business apps. This is a problem for businesses with many branches and users worldwide.
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 connects the business site to their private network, as well as to public internet. It provides reliability and cost efficiency while providing seamless user experience.
Global Scalability SD-WAN enables your enterprise to extend its network beyond the datacenter and directly connect to cloud networks, services, and intelligent application steering over multiple connections.
SD-WAN allows branches and remote offices, instead of MPLS that requires complex configurations at each branch office, to connect with critical business applications using cost-effective broadband Internet links. You can reduce costs, while still giving your users access to the tools and productivity they require, no matter where they may be.
SD-WAN managed services are available from multiple providers. GCX provides four options for your organization to choose from: proactive, reactive, fully-managed overlay or self-managed with uCPEs.
GCX's fully managed SD-WAN solution removes the burden of purchasing, installing and managing networking hardware from multiple vendors at each of your sites, while simultaneously eliminating deployment and support issues often associated with DIY SD-WAN solutions. By choosing GCX's fully managed service, you get access to global SLAs from carriers and 24/7 support from engineers specializing in WAN connectivity technology as well as NFV/SDN. GCX engineers will be able to identify any issues that may arise with your SD-WAN overlay or underlay circuits.
