Kubernetes's serverless ecosystem is growing. We talked about Knative in a previous Radar; now we're seeing Fission gaining traction. Fission lets developers focus on writing short-lived functions and map them to HTTP requests while the framework handles the rest of the plumbing and automation of Kubernetes resources behind the scenes. Fission also lets you compose functions, integrate with third-party providers via web hooks and automate the management of the Kubernetes infrastructure.
