Abstract: Techniques are disclosed for deploying, by a packet processing system in a cloud computing environment, microservice instances in the cloud computing environment comprising a plurality of computing devices executing a plurality of Kubernetes clusters comprising one or more containers. The packet processing system is configured to selectively steer data traffic between multiple versions of microservice instances executing in the cloud computing environment.

Abstract: Techniques are disclosed for providing method for providing an event timer for event synchronization across Kubernetes clusters. The event timer is configured to provide event synchronization on behalf of microservice instances in the cloud computing environment. In response to a request for an event timer for a timed event, it is determined whether the requested event timer has been started for a second microservice instance. If the requested event timer has been started, a state of the requested event timer is sent to the first microservice instance If the requested event timer has not been started, the requested event timer is instantiated, and a state of the instantiated event timer is stored in a database. The instantiated event timer is independent of the first and second microservice instances. In response to an expiration of the event timer, a single callback for processing of the event is generated.
