Azure Functions primer - LDNA01-2019


Published on

Limerick DotNet-Azure User Group (LDNA) 14 January 2019 Meetup (
Azure Functions primer

This time we will review the basics of a major serverless technology: Azure Functions.

The idea is to cover all the bases: how to setup a Function, debug, update, scale, secure. Hopefully we will touch some context, like costs and scenarios.
