A platform for packaging, distributing, and running applications is called Docker. Any system, including a developer's laptop, systems installed on-site, or systems in the cloud, can run Docker applications because they are run in containers.
Containerization
The technology of containerization has been around for a while, but Docker has given it new life. Applications are packaged as images that include the code, runtime environment, libraries, and settings necessary to run them. Containers, which are independent processes that need the same amount of resources as any other executable, are where images are executed. It's vital to remember that Docker containers share a Linux kernel rather than running in separate virtual machines. Containers require less memory and less CPU than virtual machines.
