In computational architecture, a container is a lightweight, standalone, and executable software package that contains all the necessary code, runtime, system tools, libraries, and settings required to run an application. Containers are commonly used to deploy and run applications seamlessly across different environments, such as development, testing, staging, and production environments, without worrying about dependency issues and differences in operating systems. They provide an isolated and standardized environment that allows multiple containers to coexist on the same host system without interfering with each other. Some popular container technologies include Docker, Kubernetes, and OpenShift.
