What is Container?
Cloud containers are a logical packaging mechanism by which an application is isolated with all its code, configurations, and dependencies as a single package that can be run quickly and efficiently on different computing environments. Containers are considered an effective and powerful tool for rapidly developing, deploying, managing and moving applications and other software-based components from computing environment to another. Cloud containers have been proven instrumental in boosting the speed of development and deployment of cloud computing regardless of the target environment, whether it is a private cloud, a public cloud, or even a hybrid cloud solution.
Points to Remember
- Containers generally isolate an application from rest of the environment by creating a unique virtual space known as a sandbox. This way developers can build and test customised containers with different versions of programming language, software libraries and runtimes.
- Containers are used by many renowned cloud providers such as Google Cloud Platform, Amazon Web Services (AWS), [link to #1.4] Microsoft Azure, [link to #1.5] etc.
Docker is a prominent tool that enables developers to easily create, deploy, and run applications by using containers.
