Abstract

Techniques for heat management in a serverless managed database service in a cloud provider network are described. The service receives a request to launch a database instance that can scale resource usage based on a computing resource demand of a database application. A set of candidate host computer systems to host the database instance is identified. A host resource usage metric of each host computer system in the set of candidate host computer systems is obtained. A host computer system from the set of candidate host computer systems is selected to host the database instance, the selection based at least in part on the host resource usage metric of the selected host computer system. The database instance is launched on the selected host computer system.

Claims20

Dependent claims

A computer-implemented method comprising:

receiving, by a serverless managed database service of a cloud provider network, a request to launch a database instance that can scale resource usage based on a computing resource demand of a database application;
identifying a first set of candidate host computer systems to host the database instance;
obtaining a host resource usage metric of each host computer system in the first set of candidate host computer systems;
selecting a first host computer system from the first set of candidate host computer systems to host the database instance wherein the host resource usage metric is based at least in part on a resource consumption of a database application executing in another database instance hosted by the selected first host computer system;
launching the database instance on the selected first host computer system, wherein the database instance is of a processing layer of a database of the serverless managed database service, wherein the processing layer is separate from a storage layer of the database;
selecting the database instance, of a plurality of database instances hosted by the first set of candidate host computer systems, for migration to another host computer system, wherein the selection is based at least in part on an analysis of instance resource usage metrics of the plurality of database instances, the instance resource usage metrics including a page mutation rate;
and
initiating a migration of the database instance from the first host computer system to a second host computer system.

6 more elements

A system comprising:

a first host computer system of a cloud provider network;
and
a first one or more electronic devices to implement a serverless managed database service in the cloud provider network, the serverless managed database service including instructions that upon execution cause the serverless managed database service to:
receive a request to launch a database instance that can scale resource usage based on a computing resource demand of a database application;
identify a first set of candidate host computer systems to host the database instance;
obtain a host resource usage metric of each host computer system in the first set of candidate host computer systems;
select the first host computer system from the first set of candidate host computer systems to host the database instance;
launch the database instance on the first host computer system;
select the database instance, of a plurality of database instances hosted by the first set of candidate host computer systems, for migration to another host computer system, wherein the selection is based at least in part on an analysis of instance resource usage metrics of the plurality of database instances, the instance resource usage metrics including a page mutation rate;
and
initiate a migration of the database instance from the first host computer system to a second host computer system.
