Serverless computing has been all the rage recently. I’ve spent a little time playing around with AWS Lambda and found it interesting, but never really used it for more than tinkering.
Microsoft recently released Azure Serverless Computing Cookbook, a free ebook that walks you through creating a sample application using Azure Functions. The 300+ page book does a nice job of covering the basics and starts you down the path of using Azure Functions for more advanced uses.
If you don’t know C#, no problem. For the most part you’re copy and pasting code from the book. While that doesn’t help you learn C#, if does get you familiar with Azure Functions capabilities, including integrating third-party apps/APIs like SendGrid and Twilio.
