Kubernetes Is Not Your Platform, It's Just the Foundation @ Tech Community Day Guatemala, Jun 2020
1 like184 views
The document discusses the role of Kubernetes as a foundational technology rather than a complete platform, emphasizing the need for organizations to clarify service boundaries and reduce cognitive load on teams. It argues for treating the platform as a product with a focus on self-service capabilities and collaboration between teams. Key metrics for success include deployment frequency, mean time to restore, and user satisfaction.
