Docker

Docker is a platform for building, deploying, and managing applications inside lightweight, portable containers. Containers are isolated environments that include everything an application needs to run, ensuring consistency across development, testing, and production environments. With Docker, developers can avoid "works on my machine" issues by ensuring that applications behave the same regardless of the host environment. Docker allows for efficient resource utilization and scalability by enabling the deployment of multiple containers on the same system. It integrates with CI/CD pipelines for automated testing and deployment, and it has become an essential tool for modern cloud-based application development, microservices architecture, and DevOps practices.
