In the 2013, the field of cloud computing became more of a noun "Docker". Known for its light weight, it's better to solve application packaging and deployment. We've been building IaaS before, but it's quite complex and complex to achieve unified functionality through IaaS. Encapsulation of particularity into the image to achieve an almost consistent deployment method, it is "Docker", the container as the

In this example, a completed the document, released to C,c after the changes have been published to B,b read the document to a, so a process is complete. There are, of course, file versioning and other underlying facilities. 2. Service-side application market. The current client application market is controlled
