Hi Srini, Currently we are not planning to do the performance benchmarking. For load balancing and pod selection (among replicas), we are planning to rely on Kubernetes services.

I am curious to understand on whether there is any effort to do performance benchmarking. What is the type of input load? What metrics are you collecting - Number of SO service instantiations/hour? Other reason you had given is to reduce the amount of time the service is down. Yes, yet times, container restart can take minutes. Good point. When you have multiple instances of a micro-service, then the consuming micro-services need to have a way to figure out the running instances and then figure out the right instance within them to talk to. In K8S world, service meshes (e.g ISTIO) are used for this purpose. Are you using any service mesh to experiment the scenario you described?

With replica count of 2 or more (on different nodes), we want to achieve load sharing as well as we want to avoid a single point of failure in case a k8s node goes down. K8s can bring up the container in case of failure, but having more than 1 pods will keep system available while failed pod comes back.
