Traffic Director and Microservices with Stewart Reichling and John Laham
Play • 48 min

On the podcast this week, Mark Mirchandani and Brian Dorsey talk with fellow Googlers John Laham and Stewart Reichling about Traffic Director, a managed control plane for service mesh. Traffic Director solves many common networking problems developers face when breaking apart monoliths into multiple, manageable microservices. We start the conversation with some helpful definitions of terms like data plane (the plane that data passes through when one service calls on another) and service mesh (the art of helping these microservices speak with each other) and how Traffic Director and the Envoy Proxy use these concepts to streamline distributed services.

Envoy Proxy can handle all sorts of networking solutions, from policy enforcement to routing, without adding hundreds of lines of code to each project piece. The proxy can receive a request, process it, and pass it on to the next correct piece, speeding up your distributed system processes. But Envoy can do more than the regular proxy. With its xDS APIs, services can configure proxies automatically, making the process much more efficient. In some instances, the same benefits developers see with a distributed system can be gained from distributed proxies as well. To make distributed proxy configuration easy and manageable, a managed control plane system like Traffic Director is the solution. Traffic Director not only helps you facilitate communication between microservices, it also syncs distributed states across regions, monitors your infrastructure, and more.
