Portability isn’t a thing with kubernetes

Kubernetes facilitates portability because it helps standardize our software development life cycle and, most importantly, our operating model. However, it also adds management overhead to our organization, it forces us to engage with commercial vendors and to completely rearchitect our applications. Implementing portability with Kubernetes also requires avoiding any dependency that ties the application to the infrastructure provider, such as the use of cloud provider’s native services. Often, these services provide the capabilities that drove us to the cloud in the first place.

In conclusion, the portability tax is high. Make sure to pay it only for applications that truly need it and that are likely to switch infrastructure provider at some point. For all the others, don’t choose Kubernetes on the basis of a universal portability principle, just because it “sounds right”. On the contrary, adopt Kubernetes for agility, scalability and for modernizing your application architectures.
