Asynchronous fleet configuration service

A non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by a computer, cause the computer to:

• receive a configuration policy associated with a fleet of resources deployed through a service provider network, the configuration policy describing a creation policy for deploying resources in the fleet of resources and an update policy for updating resources in the fleet of resources, wherein the configuration policy identifies a minimum quantity of the resources required to be deployed or updated successfully as a threshold number of a first batch of the resources;
• determine that at least some resources in the fleet of resources are to be updated or deployed based at least in part on the configuration policy;
• begin to update or deploy the first batch of the resources according to the configuration policy;
• expose an asynchronous signaling application programming interface (API) to the first batch of the resources;
• receive, via the asynchronous signaling API, signals provided asynchronously by one or more resources in the first batch of the resources indicating statuses of the update or the deployment for the one or more resources;
• determine that the signals pass one or more conditional tests as validation;
• responsive to the validation, create entries in a data store corresponding to the statuses of the update or the deployment for the one or more resources;
• determine from the entries in the data store that the threshold number of the first batch of the resources have updated or deployed successfully;
• and
• responsive to determining that the threshold number of the first batch of the resources have updated or deployed successfully, begin to update or deploy a second batch of the resources according to the configuration policy.

An apparatus comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium having instructions stored thereupon which are executable by the processor and which, when executed, cause the apparatus to execute an asynchronous fleet configuration service configured to:
• receive a configuration policy associated with a fleet of resources, the configuration policy describing an update policy for updating resources in the fleet of resources, wherein the configuration policy identifies a minimum quantity of the resources required to be updated successfully as a threshold number of a first batch of the resources;
• determine that some resources in the fleet of resources are to be updated based at least in part on the configuration policy;
• begin to update the first batch of the resources according to the configuration policy;
• expose an asynchronous signaling application programming interface (API) to the first batch of the resources;
• receive, via the asynchronous signaling API, signals provided asynchronously by one or more resources in the first batch of the resources indicating statuses of the one or more resources;
• determine that the signals pass one or more conditional tests as validation;
• responsive to the validation, create entries in a data store corresponding to the statuses of the update for the one or more resources;
• determine from the entries in the data store that the threshold number of the first batch of the resources have updated successfully;
• and
• responsive to determining that the threshold number of the first batch of the resources have updated successfully, begin to update a second batch of the resources according to the configuration policy.
