Non-monotonic eventual convergence for desired state configuration

A computing device comprising:

• at least one processor and memory that is coupled to the at least one processor and that includes computer-executable instructions that, based on execution by the at least one processor, configure the computing device to perform actions for providing non-monotonic eventual convergence in a desired state configuration (“DSC”) environment, where the DSC environment operates using a declarative code according to a declarative programming model directed to configuration of a resource based on a target desired state as opposed to an imperative programming model to define commands to achieve the target desired state, the actions comprising:
• determining, by the computing device, the target desired state of a service declared In the declarative code;
• determining, by the computing device, the configuration to replace the resource required for the target desired state of the service;
• in response to the determination to replace the resource required for the target desired state of the service, and before enacting the target desired state, providing the non-monotonic eventual convergence to execute a first declarative action declared In the declarative code to enact a divergent state of the service which is further away from the target desired state than a current state of the service;
• replacing the resource required for the target desired state while the service is in the divergent state;
• and
• after replacing the resource required for the target desired state of the service, executing a second declarative action declared In the declarative code to enact the target desired state of the service.
