Infrastructure that manages the traffic between microservices, handling encryption and monitoring for every call so the application code does not have to.
A Service Mesh (such as Istio) takes over the network calls between the services of a distributed AI system. It encrypts traffic automatically with mTLS, handles advanced routing (for example, canary deployments for new LLM versions), and produces detailed observability telemetry, which reduces the operational load on DevOps teams.
