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.

The best partners for international organizations are those who offer global SDWAN. These companies provide access to consultants as well professional installation and 24/7 support.

Flexible WAN Access

SD-WAN, unlike traditional networking boxes that assemble hardware from multiple vendors and assemble traffic for different WAN transports and applications, intelligently optimizes the traffic. 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 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 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 using global SD-WANs can easily add or switch locations without compromising reliability, performance or security. 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-WAN can provide a range of cost benefits depending on how it is used. These include lower connectivity costs, as the SD-WAN eliminates dependence on expensive MPLS and switches to commodity broadband connections (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 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. In addition, it has built-in reliability that ensures access to users even if there is a failure of a single connection.

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 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 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.

An SD-WAN differs from traditional routers by using software to automate and simplify WAN management, making networking professionals' lives simpler in optimizing connectivity for users and business applications more quickly. This model eliminates the many difficulties of traditional WAN models, such as long deployment lead times or hub-and -spoke architectures which don't support agile software or hybrid workforce models.

Next-generation SD-WAN solutions offer solutions to these and other challenges by combining security, optimization, and routing into one integrated platform that can be deployed in the 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, 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 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, 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.
