Taking SD-WAN Global

In 2019, more enterprises will turn to SD-WAN to enable their network infrastructures on a global scale. With SD-WAN they can achieve a flexible, automated network that can dynamically anticipate and respond to changes in their business environments while migrating applications to the cloud. However, some enterprises may rush into these SD-WAN projects without realizing there are hidden challenges in the implementation process that can make such projects go off the rails before it begins. These problems are magnified when an SD-WAN is rolled out across an enterprise's international operations, including privacy concerns with user data, managing multiple local ISPs, peering latency, and the new security threats that an SD-WAN model faces. Here are seven common things enterprises could overlook when taking their SD-WAN global:

1. Global connectivity needs

Pay close attention to locations where you have branch offices that need to be connected -- but without established telecoms infrastructure -- and be realistic about your availability requirements. Choosing the right ISP and deployment is very important with branch offices that are on the perimeter of an established telecom grid.

2. Not enlisting in a managed service provider

Turn to a global service provider/integrator with the expertise and local resources to navigate and manage an SD-WAN for you. For example, a multisourcing service integration (MSI) partner can manage ISPs and other service providers on your behalf. They would also be more adept to figure out any issues, especially since they are managing both the SD-WAN infrastructure and the network underlay.

3.  A customized management model

There are a range of flexible options to determine the level of management you want to have over an SD-WAN: Do-It-Yourself (DIY), Do-It-for-Me or Co-managed SD-WAN deployment. Each model has their pluses and minuses depending on how involved you want to be in the process. But, access to a self-service portal to monitor service delivery and make network changes yourself is invaluable.

4. Having a robust SD-WAN management portal

If you choose a management model where you will play an active role, make sure you implement a unified management dashboard so that you have consistent visibility into your applications and branch offices. A portal should also enable you to easily make network changes and configure an SD-WAN on the fly.

5. Building out a comprehensive SLA

SLAs that extend to the SD-WAN customer premise equipment (CPE) are key. The repair or replacement time of a CPE is critical to ensuring continued operations of SD-WAN locations.

6. Localization

SD-WAN requirements tend to vary across applications and locations. Using service chaining and micro-segmentation, enterprises can add security and WAN optimization functions in a highly targeted way at specific regional locations where there is a need.

7. Not looping in the Security team

SD WAN brings new security requirements and possibilities. Having your security team engaged early ensures you maintain high levels of security while your architecture changes.
