Summary

Both legacy and modern applications are remedied to be a collection of interactive microservices. Microservices can be hosted and run inside containers. There can be multiple instances for each microservice. Each container can run a microservice instance. Thus, in a typical IT environment, there can be hundreds of physical machines (also called bare metal servers). Each physical machine, in turn, is capable of running hundreds of containers. Thus, there will be tens of thousands of containers. The management and operational complexities are therefore bound to escalate. This pattern comes handy in successfully running microservice-hosted containers. There are technologies, such as Istio and Linkerd, for ensuring the resiliency of microservices. This resiliency ultimately ensures the application's reliability. Together with software-defined cloud infrastructures, reliable...
