Container orchestration tools provide a layer of abstraction for developers and infrastructure teams to deal with large-scale containerized deployments. The features offered by the container orchestration tools vary between providers. However, common denominators are provision, discovery, resource management, monitoring, and deployments.
Since microservices break applications into different micro applications, many developers request more server nodes for deployment. In order to manage microservices properly, developers tend to deploy one microservice per VM, which further drives down the resource utilization. In many cases, this results in over-allocation of CPUs and memory.
In many deployments, the high availability requirements of microservices force engineers to add more and more service instances for redundancy. In reality, although it provides the required high availability, this will result in under-utilized server instances...
