Architecture Matters – Cloud Migration

Cloud migration… sounds nebulous? It doesn’t have to!
Mobile or fixed device in hand, you don’t care where the application is as long as it’s there when you need it, on the device you’re using, and performs acceptably. The cloud is increasingly where the application is. And the cloud is—simultaneously—everywhere and nowhere.
On the other hand, if you’re the IT professional, the cloud is a very definitive and unambiguous place, more often than not characterized by not being the place where your rigid traditional WAN is optimized to route traffic. Traffic running in a straight line from your branch office to your own data center is well-oiled and efficient already. All other traffic flows necessitate creaky and expensive—in performance, cost—compromises. Traffic hairpins through your data center — traffic neither destined to, nor consumed by, the data center — chewing up its bandwidth and resources. VPN access requires brain-damaging configurations of split tunneling. You’re QoS-capable MPLS circuits just don’t go to where the traffic needs to be.
The startling thing about cloud migration is that it isn’t just about applications. Or even just about data centers. It’s every bit as much about the connective tissue weaving together the applications, branch offices, data centers, and cloud locations. Yes, by all means migrate your apps to the cloud, but then make sure to extend your SD-WAN right up there with it—the more elements in the traffic delivery path that are cloud-based, the more agile the entire structure becomes.
A Cloud-Delivered SD-WAN delivers traffic optimally, directly, from source to the—increasingly cloud-based—destination. Hosted cloud gateways are already deployed in front of the cloud data centers you are using or want to use. Self-provision your slice of these gateways—using role-based, true multi-tenant cloud-based orchestration portals—and you have a ready-at-a-click, appropriately-situated VPN aggregation point for traffic destined to the cloud application. These gateways also extend network segmentation capabilities—for multiple customers, or multiple VRF segments for a single customer—into the cloud. Cloud-based solutions give you superior link optimization, business-class “Internet” service, and end-to-end traffic monitoring and policy control.
To provide optimal and secure access to cloud applications, put a Cloud-Delivered SD-WAN between the users and the application. This makes cloud migration—of the applications and the SD-WAN—an integral part of an overall architecture and not a migraine of [the proverbial] square pegs and round holes.
Yes, architecture matters.
