Design Microservices Architecture with Patterns and Principles - What Is Docker?

The video tutorial introduces Docker, an open platform for developing, shipping, and running applications. It explains the concept of containers as a standard unit of software that packages code and dependencies, ensuring applications run reliably across different environments. Docker's methodologies enable quick software delivery by separating applications from infrastructure, reducing delays between code writing and production. Docker automates application deployment as portable containers that can run on cloud or on-premises environments. Docker containers are compatible with Linux and Windows, and the platform is a standard for microservices containerization.
