Abstract
Systems and methods are described for controlled migration of workloads between cell systems arranged in a cell-based architecture. Each cell system can implement a portion of an overall workload of the architecture, which may represent a network-accessible service. The isolation provided by cells may prevent widespread problems at the service, but may also conceal errors that might occur should workloads between the cells be redistributed. Such redistribution is often forced at inopportune moments, such as when a cell of the service has already failed. Systems and methods described herein enable detection of such errors by repeatedly migrating portions of workloads between cells. The system can monitor health information during or between migrations to ensure continued health of the service. If the service appears to be unhealthy after a migration, future migrations can be halted to enable a cause of the unhealthy state to be identified and rectified.
