The document discusses serverless computing on Kubernetes using the Fission platform. It provides an overview of Fission concepts and architecture, including that Fission allows running serverless functions on Kubernetes, hides underlying complexity from developers, and optimizes resource usage. It also describes Fission features like event queues, function environments, composing functions into workflows, and monitoring. A demo of Fission is mentioned.

4. Table of functions!
• Why Kubernetes?
• Motivation behind fission
• Fission concepts, architecture & features
• Demo
• More?

5. Why kubernetes?
• Not everything is a function
• Need enabling systems (DB, MQ)
• Common/cross-cutting concerns(Logs, Monitoring)
• General extensibility (Like
ThirdPartyResources/CustomResources)
• Multi cloud / cloud neutral

6. Why?
• Hide underlying complexity for Developer
• Optimize resources – not all workloads need to be running 24x7
• Cluster capacity as function of actual usage rather than deployed
capacity

7. Fission: Terminology
• Function
• Execution logic
• Environment
• Generic environment in which logic will execute
• Route/Trigger
• Events on which functions will be invoked

11. Fission: Features
• Event queues (NATS.io; cloud-specific queues)
• More powerful environments (packages,
compile step)
• Composing functions together into Workflows
• Monitoring: Prometheus, OpenTracing/Zipkin
• Autoscaling for functions
• Fission UI
