A system including a data plane including a first virtual machine designated as a primary node and a second virtual machine designated as a secondary node, and a lock service configured to control changes in designation of the primary node and the secondary node. The first virtual machine repeatedly issues requests to the second virtual machine or lock service extending designation as the primary node for a first duration. The request is repeatedly issued within a duration shorter than the first duration. The second virtual machine receives an indication of the designation of the first virtual machine as the primary node being extended, issues a request to the lock service to change the designation of the primary node after passage the first duration of time without further indication of first virtual machine being extended as primary node, and receives confirmation from the lock service of the change in designation.
