Failover of interrelated services on multiple devices

摘要

A device may include a network interface for communicating with a failover device, a memory for instructions, and a processor for executing the instructions. The processor may execute the instructions to communicate with the failover device, via the network interface, to fail over the device to the failover device in a cluster by pushing a process on the device to the failover device when a first failover event occurs. The failover device is configured to fail over the device to the failover device by pulling the process on the device on the second device when a second failover event occurs. The device is in the cluster.

1. A system comprising:
a first device, in a cluster, configured to:
fail over the first device to a first failover device in the cluster by pushing a first process on the first device to the first failover device when a first failover event occurs; andfail over a second device to a second failover device after failing over the first device to the first failover device; the first failover device configured to:
fail over the first device to the first failover device by pulling the first process on the first device to the first failover device when a second failover event occurs; andfail over the second device to the second failover device after failing over the first device to the first failover device when the second failover event occurs; the second device, in the cluster, configured to:
fail over the first device to the first failover device when the first failover event occurs; andfail over the second device to the second failover device by pushing a second process on the second device to the second failover device after failing over the first device to the first failover device when the first failover event occurs; and the second failover device, in the cluster, configured to:
fail over the first device to the first failover device when the second failover event occurs; andfail over the second device to the second failover device by pulling the second process on the second device to the second failover device after failing over the first device to the first failover device when the second failover event occurs.
