Problems solved by technology

However, backup applications frequently, especially when the application data volume is large, the backup overhead will be very large
At the same time, since the application program itself is interfered when the application data is backed up, the time difference should not be too small

Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, in the solution of the present invention, the layout of the physical memory used by the operating system is re-planned. Place the system memory at the low end of the physical memory, and put the memory used by the business in the rest of the memory. Different from the way the existing operating system divides the physical memory of business programs, a new business metadata memory area is added between the business memory and the system memory. This area completely describes the division and usage information of all business memory. Through this metadata information, the data structure required for the normal operation of all businesses on the system can be reconstructed.

[0035] Statistics show that more than 80% of system failures are caused by software failures rather than hardware...

Abstract

The invention relates to a service high availability method of a cloud computing data center. The method comprises the steps of (1) allocating the system memory of a computing node, (2) managing the system memory of the computing node, and (3) setting the program loading of the operating system of the computing node. According to the method, the memory data in a service operation process is reused, and the implementation overhead is small. When the load of the computing node in the cloud computing data center is uneven, the method can be used to realize fast task migration, and thus rebalancing the load of the whole system is realized. When the capacity of the physical computing node of the cloud computing data center is insufficient, the method can be used to rapidly migrate existing service to a new node, or when the service rate of the existing physical node is insufficient, the method can be used to migrate and gather the existing service, the use number of physical nodes is reduced, and the elastic expansion and contraction of cloud computing data center service are realized.

Description

technical field [0001] The invention belongs to cloud technology, and in particular relates to a high service availability method of a cloud computing data center. Background technique [0002] Cloud computing is a new way of using shared resources, which has changed the traditional mode of using all local physical resources. Users only need to connect to the cloud computing data center through the network, and put forward a demand description for computing, storage, network and other resources. The cloud computing data center will perform resource scheduling according to the demand description and allocate actual physical resources to run user applications to meet user needs. need. [0003] The cloud computing data center is composed of resources with large scale and different rules and parameters distributed in different regions. These resources are physically connected through the network, and logically unified through the resource information collection, management, and...
