This article mainly explains "what are the benefits of using docker container". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what are the benefits of using docker container".

Based on the container, docker encapsulates further, from file system, network interconnection to process isolation, which greatly simplifies the creation and maintenance of the container. It makes Docker technology lighter and faster than virtual machine technology.

In terms of performance, the container basically does not consume additional system resources except for running the applications in it. Even hypervisor support in virtual machines is saved. Therefore, the performance of the application is further improved, and the overhead of the system is as small as possible.

It takes 10 virtual machines to run 10 different applications in the traditional virtual machine mode, while Docker only needs to start 10 securely isolated applications.

Easier to maintain

With Docker, you can replace a lot of previous update work with only a small change. All changes are distributed and updated incrementally, resulting in automated and efficient management.

Compared with kvm and other virtualization methods, as a new virtualization method, Docker and traditional virtualization methods have many advantages. The startup of Docker containers can be achieved in seconds; Docker has a high utilization of system resources, and thousands of Docker containers can be run simultaneously on a single host.

Faster delivery and deployment

For developers and operators (devop), what they want most is to create or configure it all at once, which can run smoothly anywhere.

Developers can use a standard image to build a set of development containers, and after development is complete, operators can directly use this container to deploy code. Docker can quickly create containers, quickly iterate over applications, and make the entire process visible, making it easier for other members of the team to understand how the application is created and works.

Docker containers are lightweight and fast is a native feature. The start-up time of the container is at the second level, which saves a lot of time for technicians to develop, test and deploy.

More efficient virtualization

The operation of the Docker container does not require additional hypervisor support, it is kernel-level virtualization, so higher performance and efficiency can be achieved. This is the greatest thing about docker.

Easier migration and expansion

Docker containers can run on almost any platform, including physical machines, virtual machines, public clouds, private clouds, personal computers, servers, and so on. This compatibility allows users to "build all over the world at once". The simplest way is to copy and migrate an application directly from one platform to another.

Thank you for reading, the above is "what are the benefits of using the docker container" content, after the study of this article, I believe you have a deeper understanding of what the benefits of using the docker container are, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
