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.

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 Access

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. 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-WANs designed for business solve these issues by delivering consistent application performance regardless of the network conditions.

Business-driven SD-WAN can also support multi-cloud initiatives by providing direct connectivity to public and private enterprise clouds out-of-the-box. This allows users secure access to cloud/SaaS services from remote sites over an encrypted network, while optimizing the performance and security of critical apps across any WAN link.

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 connect directly to enterprise datacenters over a secure network and offer cloud and internet access through a single policy engine. They also provide central management, zero-touch provisioning and advanced analytics capabilities to speed up cloud onramps.

Reduced Costs

SD-WAN offers a number of cost savings depending on the use case. For example, it can reduce connectivity costs when switching from expensive MPLS connections to commodity broadband connections like fiber, cable, or DSL. In addition, SD-WAN lowers upgrade and equipment refresh costs by centralizing management policies to decrease individual routing programming requirements.

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. 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. What option best meets the performance requirements of your applications and users depends on how well your team is trained and if you are willing to try new things. Alternatively, hybrid deployments that combine SD-WAN with WAN optimization and firewall capabilities may also be suitable.

Secure Connectivity

SD-WANs for business centralize network functions, offer greater visibility and provide direct access to SaaS or IaaS cloud apps via local internet breakouts (not VPN). They improve app performance and user experience, while simultaneously improving productivity and lowering deployment costs.

Legacy solutions might offer some degree of security. However, their inability ensure reliable and high performance connections for essential business apps and services can present a formidable barrier for businesses that have multiple branch locations and global users.

SD-WANs are different from traditional routers because they use software to automate WAN management and make it easier for networking professionals to optimize connectivity and applications faster. 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 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.

SD-WAN, as opposed to MPLS which requires complex configurations and maintenance in every branch office to ensure performance, allows your branches and remote locations to connect to vital business applications via cost-effective commercial Internet and broadband links. This allows you to reduce costs and give users the tools they need to increase productivity, regardless of where they are located.

SD-WAN, a managed service, is offered by multiple providers. GCX offers four options to meet the needs of any organization: proactive overlay, reactive overlay, fully managed overlay and self managed solution with uCPEs.

GCX’s SD-WAN solution is fully managed, which eliminates the headaches of managing and purchasing networking hardware from different vendors. It also eliminates issues associated with DIY SD WAN deployments and support. 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 are able to identify and resolve issues with both your SD-WAN overlay as well as the underlay circuits.
