Java Serverless in Action - Voxxed Banff
This document discusses Fn Project, an open source container-native serverless platform. It allows users to write small bits of code called functions that can be easily deployed, invoked and scaled independently in the cloud or on-premises. Fn Project supports many programming languages including Java, Go, Python and JavaScript. It uses Docker containers to wrap and run functions and provides tools for monitoring, management and rapid development of serverless applications.
