In a podcast episode featuring Zack Butcher, a founding engineer at Tetrate, the discussion delves into the origins and evolution of Istio, an open-source service mesh project initially developed at Google to address various API-serving challenges such as shared outages, noisy neighbors, and cost accounting. The conversation highlights Istio's journey from its beginnings as a solution to internal Google issues to a broader open-source project aimed at solving complex networking problems in the community. Butcher emphasizes the importance of focusing on a single problem when implementing Istio, suggesting incremental adoption to manage its complexity effectively and advising users to plan for ongoing operations, including upgrades. He also touches on the value of managed Istio services to reduce operational burdens, and suggests leveraging resources like Tetrate Labs for further guidance.
