Containerization

Containerization is a type of virtualization that bundles all parts of an application into a single container image, allowing it to run in an isolated user space on a shared operating system. These containers are lightweight, portable, and excellent for automation. Thus it enables developers to create and deploy applications more quickly and securely. Traditional methods often lead to errors when transferring code between different environments, but containers eliminate this issue by maximizing resource use and minimizing overhead. The three basic steps of containerization include packaging the application and its dependencies into a standard file format like a Docker image, deploying the packaged application into a container, and executing the containerized application in the container runtime environment. Docker is a popular tool that packages applications into containers, helping developers build, ship, and run secure applications. Kubernetes, on the other hand, manages and coordinates these containers in production, automating tasks like scaling, load balancing etc. Together, Docker and Kubernetes work as complementary technologies, streamlining the containerized development process.
