Facing K8S, the history of SOA, Linkerd how to connect the past and the next, let the enterprise a good transition

[juaby]

I prefer Linkerd for performance and security, and Istio for extension.

Therefore, by extension, I ask the following question:

1. How to customize the privatization network protocol?
2. How to customize the privatization route?

For example: I want to intercept MySQL requests in Linkerd-Proxy, then route by SQL, and finally access the MySQL instance in the back segment
