A friendly introduction to Serverless computing around the MongoDB ecosystem for rapid application building. 

Do you want to crank out features the business wants, or spend a lot of time writing code and capacity planning for authentication, authorization, and complicated data access? Of course we all know the answer.

In this session we'll begin a beginner friendly introduction to Serverless computing. We will then do a quick overview of the MongoDB ecosystem in the 3 major cloud providers for rapid application building. Then we will walk through a guided tutorial of how to use the MongoDB Stitch serverless platform to build your elastically scalable microservices based app within minutes, complete with end-user authentication and access rules, on a fully managed MongoDB cluster in your favorite cloud platform.

A Gentle Introduction to Building Serverless Apps

For a long time, JavaScript was missing any kind of processing threads. While the single-threaded model added to developer comfort, it also made the platform unable to do serious and time-consuming calculations, and the only way to circumvent it was to do it on a remote server. 

Luckily, with the introduction and widespread adoption of Web Workers, we can now do resource-intensive calculations on background threads. A Web Worker allows you to run JavaScript in the background, without affecting the performance of the page. Even if you are running really resource intense code in the browser, you can continue to do whatever you want: clicking, selecting things, etc., while the Web Worker runs in the background. 

In this talk, we will explore: 
* Web Workers, how and when you can use them, and their peculiarities. 
* Perf and framerate benefits (with data!) 
* Polyfilling for naughty browsers 
* Future: WebGL, Canvas2D, and other marvels browser vendors are cooking up.
