PutProvisionConfig

Background information

You can use provisioned instances to respond to function invocation requests. This reduces the occurrences of cold starts and improves the response speed for latency-sensitive online services. You can perform scheduled auto scaling or metric tracking auto scaling to make better use of provisioned instances. For more information, see Auto-scaling of reserved instances.

Request headers

This operation uses only common request headers. For more information, see Common parameters.
