Istio Version Control On Kubernetes

Istio has been adopted as a common implementation of service mesh, since more and more companies want to bring Istio into production, the version control of Istio seems a significant problem to solve.

Version control is necessary as Istio components can be treated as the equivalent RPC services like our business services, we need to have an understanding of which version we are using now and what does the next version bring. And some Istio components can cooperate with the others, if we need to upgrade one component we need to upgrade the other components too.

Although the Istio community provides the Istio upgrade method, we don’t actually want to upgrade such a whole thing in one move, it influences so much that we don’t want to risk.
