Our Chief Technology Officer, Jamie Pugh, was recently interviewed by a partner on the top 5 considerations for SD-WAN solutions development. Here’s a short excerpt from the interview:
1) Existing infrastructure and performance:
What is the customer’s current network architecture and performance, down to the application level? What is their end goal for network and digital transformation? What is their end-user experience today and where do they want to be? With an understanding of the customer’s cloud strategy, we can incorporate OTT (Over-The-Top) SD-WAN platforms with Microsoft Azure Virtual WAN, AWS Transit Gateway, and GCP Cloud Hub to give them that carrier independent ‘private network’ over the world’s largest and best performing fibre networks.
What is their current network topology? What service levels do they expect from their SD-WAN network? What is their business continuity strategy? Would the customer want to incorporate wireless 4G/5G capabilities? Network selection can make a huge difference with regards to resiliency and performance. There’s always a trade-off between performance and cost, so helping customers evaluate the different connectivity options is key to meeting customer expectations.
"At the end of the day, SD-WAN is not a simple, check-box configuration and deployment. All the marketing materials make it sound easy, but this has proven not to be the case. Even after the considerations mentioned, careful thought and planning need to go into the deployment phase, including integration into the customer’s applications at the data center and into the cloud. Another important deployment consideration is migration. If the customer has a full mesh environment, how do you ensure that legacy MPLS/DMVPN sites can still communicate with the sites that have been migrated to the SD-WAN solution? These are considerations that a proven partner will know to address upfront before proposing the SD-WAN solution.”
