Systems and methods for enabling a highly available managed failover service

A computing system comprising:

• a computer-readable memory storing executable instructions;
• and
• one or more computer processors in communication with the computer-readable memory, wherein the one or more computer processors are configured to execute the executable instructions to at least receive configuration information comprising:
• identifiers for individual cells of a plurality of cells of an application distributed across a plurality of zones of a network-based system, the plurality of cells including at least a primary cell and a secondary cell,
• a defined state for individual cells of the plurality of cells,
• one or more dependencies for the application, and
• a failover workflow defining actions to take in a failover event based on the defined state for individual cells and the one or more dependencies;
• wherein the one or more computer processors are further configured to execute the executable instructions to at least:
• receive a request to initiate the failover event,
• update the states for corresponding cells of the plurality of cells based on the failover workflow, and
• update the one or more dependencies for the application based on the failover workflow.
