I am looking for ball park numbers in production for following questions
1) How many flows(5 tuple: SRC-IP, DEST-IP, SRC-PORT, DEST-PORT, Protocol) does a pod open and how long these flow live ?.
2) When one moves from VM's to containers with K8, Is it typical to convert a VM in to a Pod ?
Are there any studies around this area ?. If so, can you provide pointers ?
1:
It depends on how many containers or connections your pod will make.
2: It is definitely different thing: Pod is a group of containers which is managed by K8s. VM is a Virtual Machine, you can't convert VM into a pod.
Usually, when you migrate from VMs to K8s, you change the architecture of your application.
