Packaging applications - VMs, Docker
Containerization is a method of packaging an application along with its dependencies, libraries, and configuration files into a single unit called a container. This ensures that the application runs consistently across different computing environments.
Key Principles of Containerization
1> Isolation: Containers provide a sandboxed environment, isolating the application from the host system and other containers. This isolation is achieved through OS-level virtualization, where containers share the same host kernel but have separate namespaces and resource control mechanisms.
2> Portability: Containers can run on any system that supports containerization, such as Linux, Windows, and Mac operating systems. This makes it easier to develop, test, and deploy applications across different environments without worrying about compatibility issues.
3> Efficiency: Containers are lightweight and have minimal overhead compared to traditional virtual machines (VMs). They share the host OS kernel, which reduces the need for duplicating the OS in each container, leading to better resource utilization and faster startup times.
Docker is the most popular containerization platform that simplifies the creation, deployment, and management of containers. It consists of several key components.
