Enterprises utilizing software-defined wide area networking (SD-WAN) for cost savings often envision the complete replacement of multi-protocol label switching (MPLS) lines. While reliable and secure, MPLS can get costly, particularly as enterprises invest in bandwidth-hungry cloud solutions with specific performance requirements.
When SD-WAN came on the scene, many enterprises identified it as the solution to their networking troubles. Not only did it offer better visibility, scalability, and centralized control, it also introduced traffic optimization and pathway autonomy. Network engineers could prioritize traffic based on the critical nature of the transmission and relegate non-mission critical traffic to the public internet.
The problem is that the public internet has nowhere near the security needed for traffic that was previously transmitted on MPLS lines. The solution is a privately managed network that is based in the cloud and operates at the global level – offering the performance and low latency that cloud solutions require. It also offers security that’s baked into the solution.
Performance: One of the first priorities that leads to the adoption of a private cloud backbone is performance. Enterprises choosing an SD-WAN solution should examine network construction as well as the terms of the service level agreement to see what is being guaranteed. Rather than a public internet option that negatively impacts performance, enterprises need a global private cloud network with a predictable and efficient performance level.
Security: Choosing a private backbone rather than the public internet for SD-WAN also improves security. When enterprises are forced to backhaul traffic to a central security function, it increases latency and impacts application performance. In the case of SD-WAN, cloud traffic can go directly to the internet if each branch office has a secure, direct internet access. This requires additional security appliances to be deployed at each branch location.
In order to avoid this complexity, enterprises should choose a solution that offers a private backbone. It’s important to verify that the provider offers mobile security, next generation firewall, anti-malware, secure web gateways, and encryption.
Mobile Support: Any network needs to be able to support not only branch locations but also mobile users with its architecture. Ideally, there’s an agentless architecture with no software required on devices – allowing for simplified maintenance and support.
A private backbone provider that is located in the same data center as the cloud service provider can make it easy for the network to connect with multiple cloud providers.
Reducing Costs: For many enterprises, it’s the promise of reduced costs associated with MPLS that initiates the conversation surrounding SD-WAN. While any SD-WAN solution should reduce networking costs when MPLS use is reduced, it’s important to consider who owns the software in the private backbone when it comes to pricing. The difference is often tied to licensing fees and how quickly they can deliver updates and enhancements to you, the client.
