Two cloud development services -- Azure Functions and Azure App Service -- are now available on Azure Stack, which brings cloud functionality to on-premises, hybrid implementations.

Azure Functions get you beyond the traditional client/server approach to app creation, right into the cloud. Let’s first look at triggers.

There are direct bindings to key Azure services, simplifying building a Functions-based PaaS application or using a Function to control and trigger other Azure-hosted applications.

Take advantage of Azure Functions to run small pieces of code that can be triggered by events in the Azure cloud.

At JavaOne 2017, Microsoft previews its Azure Functions serverless offering with support for Java; Oracle introduces Project Fn, which runs across multiple clouds and also supports Java.
