Automated migration between shared and dedicated cloud computing database instances

A method, implemented in a computing system comprising at least one hardware processor and at least one memory coupled to the at least one hardware processor, the method comprising:

• concurrently managing a plurality of cloud database instances, the plurality of cloud database instances comprising at least one shared cloud database instance, wherein the at least one shared cloud database instance comprises a plurality of tenants;
• receiving operational data from the shared cloud database instance;
• analyzing the operational data and determining that a utilization threshold has been satisfied, indicating overutilization of computing resources of the shared cloud database instance;
• based on determining that the utilization threshold has been satisfied, migrating a tenant of the shared cloud database instance to a dedicated cloud database instance, wherein the dedicated cloud database instance is configured for use by a single entity, wherein the migrating comprises copying data for the tenant from the shared cloud database instance to the dedicated cloud database instance and allocating resources from a cloud computing system to the dedicated cloud database instance;
• and
• removing the tenant from the shared cloud database instance, the removing the tenant comprising releasing cloud computing resources previously reserved for the tenant, wherein the migrating reduces computing resource use at the shared cloud database instance.

One or more non-transitory computer-readable storage media comprising:

• computer-executable instructions that, when executed by a computing system comprising at least one hardware processor and at least one memory coupled to the at least one hardware processor, cause the computing system to concurrently manage a plurality of cloud database instances, the plurality of cloud database instances comprising at least one dedicated cloud database instance and at least one shared cloud database instance, wherein the at least one shared cloud database instance comprises a plurality of tenants and the dedicated cloud database instance is configured for use by a single entity;
• computer-executable instructions that, when executed by the computing system, cause the computing system to receive first operational data from the dedicated cloud database instance;
• computer-executable instructions that, when executed by the computing system, cause the computing system to analyze the first operational data and determine that a first utilization threshold has been satisfied, indicating underutilization of computing resources of the dedicated cloud database instance;
• computer-executable instructions that, when executed by the computing system, cause the computing system to, based on determining that the first utilization threshold has been satisfied, migrate the dedicated cloud database instance to form a new tenant of the shared cloud database instance, wherein the migrating comprises copying data for the single entity from the dedicated cloud database instance to the shared cloud database instance and allocating resources from a cloud computing system to the new tenant;
• and
• computer-executable instructions that, when executed by the computing system, cause the computing system to remove the dedicated cloud database instance, the removing the dedicated cloud database instance comprising releasing cloud computing resources previously reserved for the dedicated cloud database instance, wherein the migrating provides more efficient use of the cloud computing resources by allowing underutilized resources to be reallocated;
• computer-executable instructions that, when executed by the computing system, cause the computing system to receive second operational data from the shared cloud database instance;
• computer-executable instructions that, when executed by the computing system, cause the computing system to analyze the second operational data and determine that a second utilization threshold has been satisfied, indicating overutilization of computing resources of the shared cloud database instance, the second utilization threshold is the first utilization threshold or is different than the first utilization threshold;
• computer-executable instructions that, when executed by the computing system, cause the computing system to, based on determining that the second utilization threshold has been satisfied, migrate a tenant of the shared cloud database instance to a dedicated cloud database instance, wherein the dedicated cloud database instance is configured for use by a single entity, wherein the migrating comprises copying data for the tenant from the shared cloud database instance to the dedicated cloud database instance and allocating resources from a cloud computing system to the dedicated cloud database instance;
• and
• computer-executable instructions that, when executed by the computing system, cause the computing system to remove the tenant from the shared cloud database instance, the removing the tenant comprising releasing cloud computing resources previously reserved for the tenant, wherein the migrating reduces computing resource use at the shared cloud database instance.
