Managing the xDS traffic volume and sidecar connectivity to istiod is crucial for maintaining a performant and reliable service mesh. Non-application traffic, such as control plane and DNS queries, can significantly contribute to cloud costs in a non-obvious way. This session will delve into the specifics of the xDS API, exploring how configuration changes are distributed to sidecar proxies, the payloads of these updates, triggers, and the impact of this traffic on overall performance and cloud expenses. We will also examine how DNS queries from sidecar proxies contribute to this traffic and identify various configuration options to optimise non-application traffic and control costs. Attendees will gain practical insights for efficiently managing their service mesh deployments.
