Cloud portability is still science fiction

Enterprises want cloud portability. Why? Well, they want to hedge bets in case a public cloud provider “breaks bad” in terms of consistently poor service, or performance issues, or, more likely, jacking up the subscription fees to obnoxious levels.

As many CIOs I have talked to put it: “We need to have choices. Choices mean leverage.” I get that.

However, to have true choices, the workloads, including applications and data, need to be easily moveable from public cloud to public cloud. This means that the code will move, the data will move, and it’s a matter of recompiling, configuring, and testing on the new cloud platform. 

However, it’s never that easy. Indeed, if you’ve ported applications and data to public clouds you’ve had to refactor them to leverage some cloud-native features. These include spinning up native compute and storage servers, leveraging native security and governance, etc. It’s impractical not to leverage these native-cloud services to support your applications, else you pay way more for the workload in terms of cloud service consumption or not meeting the requirements of the business, such as security.
