FaaS functions on Kubernetes are increasingly popular. We often talk about the developer productivity advantages, such as the time to create a useful application from scratch without learning a lot about Kubernetes. In this talk, we will focus on the operational aspects of serverless applications on Kubernetes. What does it take to use serverless functions in Production, with safety, and at scale? This talk covers six specific approaches, patterns, and best practices that you can use with any FaaS/Serverless framework. These practices are geared toward improving quality, reducing risk, optimizing costs, and generally moving you closer towards production-readiness with serverless systems. We discuss:declarative configuration, live-reload for fast feedback, record-replay for testing and debugging, Canary Deployments to reduce the risk and impact of application changes, monitoring with metrics and tracing, and cost optimization. We’ll show how you can make different cost-performance tradeoffs; we’ll discuss what the defaults choices imply, and how to tune these. We also share a live demo showing how you can easily follow these practices with the open source Fission.io FaaS framework, so you can use them on any infrastructure that runs Kubernetes (whether it’s your datacenter or the public cloud).
