Today, what the editor shares with you is container technology-where are the advantages of docker? I believe many people don't know much about it. In order to make you understand better, I summarized the following contents for you. Let's look down together. I'm sure you'll get something.

Docker is developed based on the Go language, the code is hosted on Github, and the docker container can encapsulate any payload. Containers and VM have a certain degree of isolation, the data and memory of each container are isolated from each other, which can ensure a certain degree of security.

Advantages of Docker

1) Rapid deployment: hundreds of applications can be deployed in a short period of time and quickly delivered online

2) efficient virtualization: traditional virtualization is based on virtualization at the hardware level, while docker is implemented at the system level, does not require Hyprevisor-based support, and greatly improves performance and efficiency than virtual machines.

3) save money: better improve the utilization of the server

4) simplify the configuration: package the running environment into a container and start it directly when you use it.

5) Rapid migration expansion: we can quickly package and migrate containers to applications on the platform we need, with good compatibility

Here Hyprevisor can be understood as the software layer between the basic physical server and the operating system, which can coordinate the access of hardware resources.

Of course, docker container technology cannot be without its shortcomings, such as:

1) isolation: although docker provides Namespace isolation of system resources, the isolation between applications is not as good as that of virtual machines

2) Security: currently, docker server cannot determine which user started the container. For example, user permissions will not be audited when deleted.

3) Stability and functional compatibility: because the docker version is still in the process of updating and iterating, and many functions depend on the high version of the linux kernel, there are still some compatibility problems.

About container technology-where the advantages of docker are shared here, I hope the above content can have a certain reference value for you to apply what you have learned. If you like this article, you might as well share it for more people to see.
