Containerization explained: what it is, benefits and applications

Containers contain applications, including their dependencies and libraries. Developers do not have to deal with compatibility between different environments.
Containers need much less computing power to run than, for example, virtual servers because they share the core of the operating system with the guest.
Virtualisation of CPU, memory, storage, and network resources at the operating system level provides developers with an operating system that is logically separate from other applications.
You can deploy them in every OS, on a physical or virtual server and in the cloud. Use containers wherever you want to run your software.
Several containers can run on a single virtual machine, which are separated from each other and therefore easily move across different computing environments. Thanks to the shared core of the operating system, they take up less disk space and put less strain on the infrastructure.
To easily isolate applications and their libraries, developers most often use Docker, which has many functions and is easy to work with.
The most popular tool for container management and orchestration is Kubernetes. This solution will make work easier, especially for developers of micro services.
Interest in containers is growing every month mainly because they are suitable for everyone. We run smaller virtual servers with the possibility of additional container virtualisation and robust managed Kubernetes clusters.
The developers of the Netflix streaming service were among the first to start using containers in large numbers. They built the whole system on the architecture of microservices. Why did they decide for this?
