Abstract: A control-plane component of a network-accessible service receives an indication that a resource request has been submitted by a client. The component determines, based at least in part on metadata associated with the client, that a first parameter selection policy (PSP) of one or more PSPs created for the service is applicable. The first PSP includes a condition set to determine applicability, and a value set indicating parameter values to be used to fulfill resource requests to which the PSP applies. Using the value set, an effective parameter value list for one or more operations to be performed to allocate the requested resource is generated, and the allocation operations are initiated.

Abstract: A service workflow agent associated with a particular service of a provider network identifies a repository in which workflow descriptors indicative of tasks to be performed by the service are stored. In response to determining that a modification has been applied at one such repository, the agent examines a particular workflow descriptor stored in the repository. The agent initiates an attempt to implement a first task indicated in the descriptor. Subsequently, the agent updates the descriptor in accordance with an optimistic concurrency control technique to indicate a status of the first task.
