This document summarizes hot technologies discussed at Kubernetes Meetup #9, including machine learning/deep learning (ML/DL) on Kubernetes and service meshes. ML/DL on Kubernetes sessions covered building GPU-accelerated workflows with TensorFlow and Kubernetes, and democratizing machine learning on Kubernetes. Regarding service meshes, the document discusses the increasing popularity of Istio and Envoy due to advanced routing, security features, and making microservices easier to develop and deploy. Videos and slides from the meetup are available online.
