Apparatus, system and method for managing service mesh traffic in a distributed kubernetes multi-cluster environment

A service mesh traffic management system in a distributed Kubernetes multi-cluster environment comprising:

• a first cluster including a custom controller;
• and
• a plurality of second clusters including a proxy reflecting a routing policy selected by the custom controller,
• wherein the custom controller,
• receives a monitoring metric collected by a Prometheus server distributed in the second cluster,
• selects a first routing policy based on a predefined routing policy selection rule and the collected monitoring metric,
• compares the first routing policy and a second routing policy currently in use,
• distributes, when the first routing policy and the second routing policy are different, the first routing policy to each proxy of the second cluster.
