What is Docker?

Docker is a platform that simplifies the process of creating, deploying, and managing applications using containers. Containers are lightweight, isolated environments that package an application and its dependencies, ensuring consistency across different environments. Docker provides a standardized way to develop, test, and deploy applications, making it easier to move them between different systems, such as development, testing, and production environments. It has become a fundamental tool for DevOps and containerization, improving scalability and portability of software.
