As the demand for cloud computing infrastructure increased, availability and reliability have become more important as they are major features in real‐time computing systems. The chances of failure in a cloud computing system increase compared to other computing systems. To achieve high reliability and availability for the cloud computing infrastructure fault tolerance is one of the most essential modules. For a cloud computing infrastructure, a proactive fault tolerance algorithm with load balancing is proposed in this paper. The proposed methodology tolerates virtual machine CPU faults to achieve maximum cloud computing infrastructure reliability and availability. CPU faults can occur during virtual machine operation. The proposed model's main objective is to track changes in CPU utilization and make a decision once a high value of CPU utilization is identified. The decision is either to migrate the defective virtual machine to another “destination host”, or to manage loads on the destination host so that the faulty virtual machine can be migrated. A load is calculated for the destination host; if the destination host is overloaded, the subroutine for load balancing is launched. Load balancing is based on the technique of choosing a virtual machine.

云计算中的主动负载均衡容错算法

随着对云计算基础架构需求的增长，可用性和可靠性已成为更重要的组成部分，因为它们是实时计算系统的主要功能。与其他计算系统相比，云计算系统发生故障的机会增加。为了实现云计算基础架构的高可靠性和可用性，容错是最重要的模块之一。针对云计算基础设施，提出了一种具有负载均衡的主动容错算法。所提出的方法可以容忍虚拟机CPU故障，以实现最大的云计算基础架构可靠性和可用性。虚拟机运行期间可能会发生CPU故障。提议的模型” 其主要目标是跟踪CPU利用率的变化，并在确定CPU利用率高值后做出决策。决定是将有缺陷的虚拟机迁移到另一个“目标主机”，还是管理目标主机上的负载，以便可以迁移有故障的虚拟机。计算目标主机的负载；如果目标主机过载，则启动用于负载平衡的子例程。负载平衡基于选择虚拟机的技术。将启动用于负载平衡的子例程。负载平衡基于选择虚拟机的技术。将启动用于负载平衡的子例程。负载平衡基于选择虚拟机的技术。
