Description

Support for relocating containers has become a must-have requirement for most multi-service applications, since the inevitable concept-drifts make SLAs hard to be satisfied. The relocation and co-location of services (long running containers) can help to reduce bottlenecks in a multi-service cluster, especially where data-intensive, streaming applications interfere.

See the high-level implementation details in the attached design document.
