Abstract: One or more techniques and/or computing devices are provided for determining whether to perform a switchover operation between computing nodes. A first computing node and a second computing node, configured as disaster recovery partners, may be deployed within a computing environment. The first computing node and the second computing node may be configured to provide operational state information (e.g., normal operation, a failure, etc.) to a cloud environment node state provider and/or cloud persistent storage accessible through a cloud storage service. Accordingly, a computing node may obtain operational state information of a partner node from the cloud environment node state provider and/or the cloud storage service notwithstanding a loss of internode communication and/or an infrastructure failure that may otherwise appear as a failure of the partner node. In this way, the computing node may accurately determine whether the partner node has failed.
Abstract translation: 提供一个或多个技术和/或计算设备用于确定是否在计算节点之间执行切换操作。 配置为灾难恢复伙伴的第一计算节点和第二计算节点可以部署在计算环境内。 第一计算节点和第二计算节点可以被配置为向通过云存储服务可访问的云环境节点状态提供者和/或云持久存储提供操作状态信息（例如，正常操作，故障等）。 因此，计算节点可以从云环境节点状态提供者和/或云存储服务获得合作伙伴节点的操作状态信息，尽管节点间通信和/或基础设施故障的丢失可能以其他方式出现为合作伙伴的故障 节点。 这样，计算节点可以准确地确定伙伴节点是否失败。
