Architecture of elastic cloud

Abstract

The invention provides an architecture of elastic cloud. The architecture of elastic cloud comprises a cloud resource control end, an internal network, a storage device, a reverse proxy server, an external network and a server cluster, wherein the cloud resource control end, the internal network and the storage device are connected in sequence, the reverse proxy server and the external network are connected in sequence, the cloud resource control end is connected with the reverse proxy server, a software provider has access to the cloud resource control end, virtual machine images and configuration files are uploaded and are stored in the storage device by the cloud resource control end through the internal network, virtual machines are registered in the server cluster and instantiated, and the configuration files of the reverse server are modified. According to the architecture of elastic cloud, by monitoring the virtual machines running in elastic cloud, service in the elastic loud is guaranteed to be always in the healthy state according to the load dynamic flexible service capacity of the virtual machines, and it is guaranteed that after the server cluster changes, a user request can not be sent to the service virtual machines which do not exist any more.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to an architecture of an elastic cloud. technical background [0002] In recent years, with the rapid development of the Internet, more and more people have migrated their offices to the Internet, and the business volume that the Internet needs to handle has also increased rapidly. How to deal with the ever-increasing massive business and the massive data brought by the business, and provide users with convenient and fast network services has become a problem facing the current development of the Internet. Based on distributed technology and grid technology, people invented a new computing model: cloud computing. It is developed from grid computing, massive storage and parallel computing. Its core is to virtualize the data center composed of computer clusters and provide users with services in the form of renting computing resources. [0003] At present, the emergen...

AI Technical Summary

Problems solved by technology

However, for services in the cloud, the service quality is greatly affected by the load capacity of the virtual machine. When the load capacity of the virtual machine is overloaded, the service running in the virtual machine may not be able to run normally.

The current cloud computing technology has not been able to allocate resources in a timely manner according to the load capacity of the virtual machine

[0004] Moreover, once the server cluster in the cloud is changed, the software user's access service request may be sent to a virtual machine that no longer exists

[0005] At the same time, the deployment of cloud computing is too cumbersome. It is usually deployed manually. Entering commands line by line on the server command line is not only inefficient but also error-prone.
