Robust tenant placement and migration in database-as-a-service environments

摘要

Present application refers to a robust tenant placement and migration system, process and to a respective controller in database-as-a-service environments. Multiple tenants (T) are to be allocated on a set of in-memory database servers (S) such that workload changes depending on the tenants' behavior are considered, while maintaining strict service level objectives. The placement and migration is based on a migration command which is based on an interleaved placement by interleaving tenants (T) across machines.
