ABSTRACT:
In one embodiment, a method for providing consistent services semantics for multiple services running different instances of an application comprises maintaining, at a network node, data identifying current application versions associated with the multiple services, and selecting, at the network node, a new preferred application version based on the data identifying current application versions upon detecting a predefined event pertaining to the multiple services. The method further comprises identifying, at the network node, services that run the new preferred application version, and balancing the distribution of requests between the services that run the new preferred application version until detecting a next predefined event.
