What Docker is and when to use it
Docker is an open source platform that allows you to develop, deploy, and run applications in containers—isolated environments that include everything needed to run them.
Containerization ensures consistency across development, testing, and production, and makes it easy to move applications between different environments. It is also supported by a wide ecosystem of tools and best practices that facilitate its adoption.
Docker is particularly useful for:
- deploying applications quickly and consistently
- creating consistent environments across teams and project phases
- automating releases in CI/CD processes
- designing microservices architectures
