Abstract

Systems for achieving and maintaining a specified state of a computing resource in a distributed computing environment. A method embodiment commences upon receiving one or more specification parameters that describe a desired target state associated with a particular computing resource and/or of a particular computing environment. The specification parameters that characterize the desired target state of a resource are recorded in a target state data structure. Periodically, an agent issues a state progression query to determine if the computing resource has reached its desired target state. The query is then processed by collecting state parameters that describe the then-current state of the computing resource or environment. The target state data structure is accessed to identify one or more state differences between the desired target state and the then-current state of the particular computing resource and/or its particular computing environment. Remediation operations based on the state differences are then carried out.

Claims

1. A method comprising:

executing a resource management command at a processor to achieve a target resource state in a distributed virtualization computing environment;

receiving a state progression query while executing the resource management command, wherein the state progression query comprising requests for retrieval of differences between a current resource state and the target resource state and for resource state remediation operations to be applied to the current resource state;

determining a state difference between the target resource state and the current resource state;

determining a resource state remediation operation based on the state difference and a state management rule; and

issuing a response to the state progression query including the state difference and resource state remediation operations to achieve the target resource state.

2. The method of claim 1, further comprising invoking the resource state remediation operation.

3. The method of claim 1, further comprising generating the resource management command based at least in part on a specification parameter that describes the target resource state of the distributed virtualization computing environment.
