Abstract of the talk…

Almost all applications have some kind of state. Some data processing apps and databases have huge amounts of state. How do we navigate a cloud-based world of containers where stateless and functions-as-a-service is all the rage? As a long-time architect, designer, and developer of very stateful apps (databases and data processing apps), I’d like to take you on a journey through the modern cloud world and Kubernetes, offering helpful design patterns, considerations, tips, and where things are going. How is Kubernetes shaking up stateful app design? - What kind of state is there, and what are some important characteristics? - Kubernetes, containers, and the stateless paradigm (pushing state into DBs) - Where state lives and the persistence characteristics - Stateless vs serverless - why stateless is not really stateless, but server less really is - Improving on stateless paradigm using local state pattern - Logs and event streaming for reasoning about state and failure recovery - The case for local disks: ML, Databases, etc. - Kubernetes and the Persistent Volume/StatefulSets - Leveraging Kubernetes PVs as a basis for building distributed data systems - Mapping the solution space
