Overview of Kubernetes and its core concepts

Managing and orchestrating a small number of containers and containerized applications manually within a compute environment can be relatively manageable. However, as the number of containers and servers grows, the task becomes increasingly complex. Enter Kubernetes, a powerful open-source system specifically designed to address these challenges. First introduced in 2014, Kubernetes (commonly abbreviated to K8s, derived from replacing “ubernete” with the digit 8) offers a comprehensive solution for efficiently managing containers at scale across clusters of servers.
