Marco Palladino's blog post discusses the complementary roles of API gateways and service meshes, asserting that they can be used simultaneously for different use cases. The post provides a detailed guide on how to integrate Kong for Kubernetes with Kuma Mesh on Kubernetes, requiring users to have a Kubernetes cluster prepared. The process involves installing Kuma using the `kumactl` tool, deploying Kong for Kubernetes as an ingress controller, and configuring services with the appropriate annotations for seamless interaction between the gateway and the mesh. After setting up Kong and Kuma, users are instructed to add a traffic permission policy, allowing them to explore advanced features and plugins offered by Kong in conjunction with Kuma's policies.
