Introduction to Containers and Docker
In software development and deployment, containerization has emerged as a revolutionary approach, offering an efficient alternative to traditional VMs. At the heart of this revolution is Docker, a standardized container creation and management platform that makes it simpler for developers to package and deploy applications consistently across various environments.
Understanding Containerization
Containerization involves encapsulating an application and its dependencies into a lightweight, standalone executable package. Containers include everything needed to run the application: code, runtime, system tools, libraries, and settings. Although containers are isolated from each other and the host system, they share the host OS kernel, libraries, and resources as needed. This isolation ensures that applications work uniformly and securely, regardless of where they are deployed.
