What is a container?

A container is a lightweight, standalone, and executable software package that includes everything needed to run a piece of software, including the code, runtime, libraries, and system tools. Containers are isolated from each other and the host system, which allows them to run consistently across different environments. They are built on containerization technology, such as Docker, and are designed to be portable, scalable, and efficient, making them ideal for deploying applications in cloud environments and microservices architectures.
