Problems solved by technology

Due to server failure, network failure, software failure and other problems, it is difficult for the cloud computing center to guarantee that the controller in the cloud system can provide normal services anytime and anywhere. For example, Amazon’s cloud computing system in northern Virginia (Virginia). failure problem

Embodiment Construction

[0021] as attached Figure 1-3 As shown, the present invention proposes a cloud computing service state model based on monitoring whether the cloud computing controller service is normal, a cloud computing controller service restart based on the hard disk file memory mapping mechanism and a fault recovery method for starting virtual machines across computing nodes . The specific status monitoring and fault recovery are carried out according to the following steps:

[0022] The first step is to establish the memory blocks of network resources, computing node resource information, and cluster virtual machine information required by the cloud computing operating system cluster controller service, and hot backup the data structure of the memory block to the hard disk file; the node controller service follows With the creation of the virtual machine, the memory block of the virtual machine metadata is constructed accordingly, and it is backed up to the hard disk file at the same t...

Abstract

The invention relates to the technical field of cloud computing, in particular to a service state monitoring and failure recovery method for controllers of a cloud computing operating system. Service monitoring modules are respectively arranged on a cloud controller and a cluster controller; when failures of the cluster controller recover, the cluster controller is re-started to recover the network information, computing node resources and cluster virtual machine information which are managed by the cluster controller; when failures of node controllers recover, the node controllers are re-started to recover node resources and virtual machine information which are managed by the node controllers. The method provided by the invention effectively solves the problem that stored data is lost when the service recovers, ensures the high service reliability of the cloud computing operating system, and can be widely applied to the cloud computing operating system.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a controller service state monitoring and fault recovery method of a cloud computing operating system. Background technique [0002] As a new generation of network resource computing model, cloud computing has the characteristics of super computing power, low cost, high security, and user-centered. The cloud computing operating system is an infrastructure management platform for cloud computing. Through the cloud controller service, the large-scale infrastructure collection (CPU, storage, network) is fully managed as a seamless, flexible and dynamic operating environment, and servers, storage devices and network resources are virtualized and aggregated, and finally allocated to users on demand. At present, internationally renowned IT companies such as Google, Amazon, Microsoft, Oracle, IBM, and SUN are actively researching cloud computing and developing related commercia...
