At this point, you might be thinking, “I have a container orchestrator. Why do I need another infrastructure layer?”
With microservices and containers mainstreaming, container orchestrators provide much of what the cluster (nodes and containers) need.
The higher volume of service requests that you have to internal and external services there are, the more insight and control you will need and the higher the return on investment your service mesh will deliver.
Edge focus—metrics and usage are for response time to clients and request failure rates.
Service meshes provide intent-based networking for microservices describing desired behavior of the network in the face of constantly changing conditions and network topology.
