Systems, methods, and apparatuses for tenant migration between instances in a cloud based computing environment

A system to execute within a host organization, wherein the system comprises:

• a processor and a memory to execute instructions at the system, the system providing:
• means for assigning each of a plurality of tenants a dedicated share on one or more multi-tenant cloud computing services instances in a cluster of multi-tenant cloud computing services instances, the instances in the cluster each executing on one or more application servers and providing the plurality of tenants access to a database;
• means for receiving a plurality of performance characteristics for each of the plurality of tenants;
• means for analyzing the plurality of performance characteristics for each of the plurality of tenants;
• means for detecting an anomaly in one of the plurality of tenants responsive to analyzing the plurality of performance characteristics for each of the plurality of tenants;
• means for evicting the one of the plurality of tenants in which the anomaly was detected from the one or more instances in the cluster of multi-tenant cloud computing services instances to which it was assigned;
• and
• means for reassigning the one of the plurality of tenants in which the anomaly was detected a dedicated share on one or more multi-tenant cloud computing services instances other than the instance to which it was assigned before eviction.

Non-transitory computer readable storage media having instructions stored thereon that, when executed by a processor of a system, the instructions cause the system to perform operations including:

• assigning each of a plurality of tenants a dedicated share on one or more multi-tenant cloud computing services instances in a cluster of multi-tenant cloud computing services instances, the instances in the cluster each executing on one or more application servers and providing the plurality of tenants access to a database;
• receiving a plurality of performance characteristics for each of the plurality of tenants;
• analyzing the plurality of performance characteristics for each of the plurality of tenants;
• detecting an anomaly in one of the plurality of tenants responsive to analyzing the plurality of performance characteristics for each of the plurality of tenants;
• evicting the one of the plurality of tenants in which the anomaly was detected from the one or more instances in the cluster of multi-tenant cloud computing services instances to which it was assigned;
• and
• reassigning the one of the plurality of tenants in which the anomaly was detected a dedicated share on one or more multi-tenant cloud computing services instances other than the instance to which it was assigned before eviction.
