In this episode, Shweta Vohra and Joseph Stein explore what changes when software systems start planning, acting, and making decisions on their own.

AWS shipped GA support for Kubernetes Gateway API in its Load Balancer Controller, dumping annotation-based configuration for type-safe CRDs with proper validation. The release handles both L4 (TCP/UDP via NLB) and L7 (HTTP/gRPC via ALB) routing through the Gateway API spec. Teams get cross-namespace routing, automatic certificate discovery, and role separation without cluster-admin permissions.
