This article mainly introduces "what are the benefits of docker container". In daily operation, I believe many people have doubts about the benefits of docker container. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "what are the benefits of docker container?" Next, please follow the editor to study!

Docker is an advanced LXC-based container engine provided by PaaS provider dotCloud. Because of its lightweight virtualization based on LXC, the most obvious feature of docker compared with KVM is that it starts quickly and takes up less resources.

Fast and efficient development lifecycle

One of the goals of Docker is to shorten the cycle of code from development, testing to deployment and running online, so that your application is portable, easy to build, and easy to collaborate.

Simple and lightweight application modeling method

In the era of cloud computing, applications created by developers must be easily distributed on the network, that is, applications must be free from the limitations of the underlying physical hardware, and must be accessible "anytime, anywhere". Therefore, developers need a new way to create distributed applications, rapid distribution and deployment, which is the biggest advantage that Docker can offer.

Docker packages applications through containers, decoupling applications and running platforms. It means that when migrating, you only need to start the required container service on the new server, regardless of whether the new server and the old server are the same type of platform. This will undoubtedly save a lot of valuable time and reduce the risk of problems with the deployment process.

Realize the logical separation of clear responsibilities

With Docker, developers only need to care about the applications running in the container, while operators only need to care about how to manage the container. Docker is designed to enhance the consistency between the development environment in which developers write code and the production environment in which the application is deployed, so as to reduce the risk that "everything is fine during development, it must be a problem of operation and maintenance."

Encourage the use of service-oriented architecture

Docker also encourages service-oriented architectures and microservice architectures. Docker recommends that a single container runs only one application or process, which forms a distributed application model, in which applications or services can be represented as a series of interconnected containers, which makes it very easy to deploy applications, extend or debug applications, and improve the introspection of the program.

At this point, the study on "what are the benefits of docker containers" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
