Containerization in development and deployment
What is containerization and how does it work? Containerization is an increasingly popular concept in the software development world. Much lighter than traditional virtual machines, this technique allows applications and their dependencies to be grouped and managed in separate containers that are isolated from each other. You have to think of containerization as a system of layers. First, the OS, then the necessary functionality. Like virtualization, containerization is designed to isolate applications in a dedicated environment. However, its vision is more atomic and aims to reduce the scope of services as much as possible by isolating them from each other, whereas virtualization would tend to consider an ecosystem as a whole. Unlike virtualization, containerization has the advantage of not requiring the installation and configuration of a new virtualized system. [Here is a diagram illustrating the difference between a container and a virtual machine: (The host operating system is the main operating system on which a guest system, called the guest operating system, is running. The host operating system provides resources such as memory, processor, and hardware.
