FAILURE RESISTANT DISTRIBUTED COMPUTING SYSTEM

摘要

A failure resistant distributed computing system includes primary and secondary datacenters each comprising a plurality of computerized servers. A control center selects orchestrations from a predefined list and transmits the orchestrations to the datacenters. Transmitted orchestrations include less than all machine-readable actions necessary to execute the orchestrations. The datacenters execute each received orchestration by referencing a full set of actions corresponding to the received orchestration as previously stored or programmed into the computerized server and executing the referenced full set of actions. At least one of the orchestrations comprises a failover operation from the primary datacenter to the secondary datacenter. Failover shifts performance of task from a set of processing nodes of the primary datacenter to a set of processing nodes of the secondary datacenter, such tasks including managing storage accessible by one or more remote clients and running programs on behalf of remote clients.

主权项

1. A method for providing a failover between a primary datacenter and a standby datacenter, the method comprising:
detecting that a failover condition exists in the primary datacenter; stopping processing on the primary datacenter; ensuring that each database of the primary datacenter is in read-only mode; ensuring that each database of the standby datacenter is in read/write mode; redirecting communications from the primary datacenter to the standby datacenter.
