Docker

Docker is an open-source platform that enables developers to build, package, and run applications in lightweight, portable containers. Containers bundle an application with all its dependencies—such as libraries, frameworks, and configuration files—ensuring that it runs consistently across different environments, from a developer’s laptop to production servers.

Unlike traditional virtual machines, Docker containers share the host operating system’s kernel, making them faster to start, more resource-efficient, and easier to scale. Docker simplifies software deployment, encourages microservices architecture, and improves collaboration between development and operations teams.

In short, Docker helps you deliver applications quickly, reliably, and at scale.
