高可用性

高可用性通过抗故障能力为多节点 Orchestrator 部署提供冗余和稳定性，因为多个 Orchestrator 和高可用性加载项 (HAA) 节点可用 - 当一个节点发生故障时，其他节点会承担负载。 还提供水平可扩展性，因为您可以在机器人需求增长时添加另一个节点。

Please note that this model is more resource intensive compared to a simple multi-node Orchestrator deployment, requiring at least 3 HAA nodes and the attendant Hardware and Software Requirements.

下图显示了具有两个 Orchestrator 节点和三个 HAA 节点的简单高可用性部署：

This model can be easily scaled to suit any needs, including Active/Passive and Active/Active disaster recovery deployments for geo-redundancy.
