Claim 14:
15. A system to control migration of data between cells of a cell-based architecture implementing a network-accessible service, the system comprising:
a plurality of cell systems forming the cell-based architecture, individual cell systems comprising one or more computing devices configured to implement the network-accessible service on behalf of corresponding portions of clients; and
a migration manager including a processor configured with computer-executable instructions to:
analyze health information for the network-accessible service to detect that the plurality of cell systems are in a healthy state;
while each cell system of the plurality of cell systems is detected to be in the healthy state, repeatedly initiate migrations of at least a portion of a workload from one individual cell system, selected from the plurality of cell systems independently of load on the one individual cell system and at least partly at random, to another individual cell system, selected from the plurality of cell systems independently of load on the other individual cell system and at least partly at random;
analyze additional health information for the network-accessible service to detect that at least one cell system implementing the network-accessible service is in an unhealthy state; and
responsive to detecting that the at least one cell system implementing the network-accessible service is in an unhealthy state, halt the repeatedly initiated migrations.
