Migrating From Kubernetes Deployment to Knative Serving

When I talk about Knative, I often get questions on how to migrate an app from Kubernetes Deployment (sometimes with Istio) to Knative and what are the differences between the two setups. First of all, everything you can do with a Knative Service, you can probably do with a pure Kubernetes + Istio setup and the right configuration. However, it’ll be much harder to get right. The whole point of Knative is to simplify and abstract away the details of Kubernetes and Istio for you. In this blog post, I want to answer the question in a different way. I want to start with a Knative Service and show how to setup the same service with Kubernetes + Istio the ‘hard way’.
