Managing cloud computing resources hosting instances with customizable baseline compute performance

A computer-implemented method comprising:

• executing, by a host system of a cloud provider network, a compute instance, wherein the host system provides the compute instance with a baseline compute performance;
• receiving a request to change the baseline compute performance of the compute instance, wherein the request includes an indication of a new baseline compute performance;
• determining, by a baseline management service implemented as baseline management service code executing on one or more processors in the cloud provider network, to grant the request, wherein determining to grant the request comprises:
• determining an available baseline capacity of the host system;
• determining that a difference between the baseline compute performance and the new baseline compute performance exceeds the available baseline capacity of the host system;
• based on determining the difference between the baseline compute performance and the new baseline compute performance exceeds the available baseline capacity of the host system, obtaining an estimated time to live migrate another compute instance executing on the host system to another host system;
• determining the estimated time is below a threshold specified in a live migration policy requirement;
• based on determining the estimated time is below the threshold specified in the live migration policy requirement, initiating a live migration of the another compute instance executing on the host system to the another host system;
• and
• based on determining the estimated time is below the threshold specified in the live migration policy requirement, determining to grant the request to change the baseline compute performance of the compute instance;
• and
• updating a configuration of the host system to change the baseline compute performance of the compute instance to the new baseline compute performance while the compute instance remains in an executing state.

A system comprising:

• a host computer system of a cloud provider network, the host computer system including instructions that upon execution cause the host computer system to:
• execute a compute instance, wherein the host system provides the compute instance with a baseline compute performance;
• and
• a second one or more electronic devices to implement a baseline management service in the cloud provider network, the baseline management service implemented as baseline management service code including instructions that upon execution by one or more processors in the cloud provider network cause the baseline management service to:
• receive a request to change the baseline compute performance of the compute instance, wherein the request includes an indication of a new baseline compute performance;
• determine to grant the request based at least in part on one or more instructions to:
• determine an available baseline capacity of the host system;
• determine that a difference between the baseline compute performance and the new baseline compute performance exceeds the available baseline capacity of the host system;
• based on determining the difference between the baseline compute performance and the new baseline compute performance exceeds the available baseline capacity of the host system, obtaining an estimated time to live migrate another compute instance executing on the host system to another host system;
• determining the estimated time is below a threshold specified in a live migration policy requirement;
• based on determining the estimated time is below the threshold specified in the live migration policy requirement, initiating a live migration of the another compute instance executing on the host system to the another host system;
• and
• based on determining the estimated time is below the threshold specified in the live migration policy requirement, determining to grant the request to change the baseline compute performance of the compute instance;
• and
• update a configuration of the host system to change the baseline compute performance of the compute instance to the new baseline compute performance while the compute instance remains in an executing state.
