Docker
Docker is an open-source platform that enables developers to build, deploy, and run applications in lightweight, portable containers. Containers package an application with all its dependencies, libraries, and configuration files, ensuring consistent execution across different computing environments. It uses containerization technology to isolate applications from the underlying infrastructure, improving efficiency and scalability.
Developers should learn Docker to streamline development workflows, ensure consistency between development, testing, and production environments, and facilitate microservices architectures. It is essential for modern DevOps practices, enabling rapid deployment, easy scaling, and efficient resource utilization in cloud-native applications, such as web services, APIs, and distributed systems.
