Abstract: A device executing an application in a distributed system may transmit a query for capabilities of one or more components in the distributed system to a capability service and receive a response. Based on the response, the device may determine whether a first capability criteria that is based on a first version of the application is met. If the first capability criteria is met, the device may execute the first version of the application. If the first capability is not met: the device may transmit a subscription request to subscribe to one or more particular capabilities; and optionally may determine a second version of the application for which a second capability criteria is met and execute the second version until receiving a notification to the subscription. The capability service may have a capability store that is updated upon a capability change in the one or more components in the system.

Abstract: A system and method include assigning, by an identifier management system of a virtual computing system, a hypervisor agnostic identifier to a virtual machine. The system and method also include creating a mapping of the hypervisor agnostic identifier to a first hypervisor specific identifier of the virtual machine, including storing the mapping in a database, and updating the mapping in response to a second hypervisor specific identifier being associated with the virtual machine. The updated mapping maps the hypervisor agnostic identifier to the second hypervisor specific identifier. The system and method further include making available the hypervisor agnostic identifier for use by other elements of the virtual computing system instead of the first hypervisor specific identifier and the second hypervisor specific identifier. The first hypervisor specific identifier and the second hypervisor specific identifier are hypervisor specific, while the hypervisor agnostic identifier is not hypervisor specific.

Abstract: A system and method include receiving, by an entity management system of a virtual computing system, a user request for performing an operation on an entity in a mixed hypervisor cluster of the virtual computing system and accessing, by the entity management system, a hypervisor library for retrieving hypervisor resources of a particular hypervisor type associated with the entity for performing the operation on the entity. The entity management system is configured to perform the operation on multiple hypervisor types. The system and method also include fulfilling, by the entity management system, the user request by performing the operation on the entity using the hypervisor resources.
