This document summarizes a talk about serverless application development using MongoDB Stitch. The talk discusses what serverless and Stitch are, how to use Stitch's QueryAnywhere, Functions, and Triggers features, and how to deploy serverless code. Serverless applications can reduce infrastructure management, allow independent deployments, and only charge for resources used. MongoDB Stitch is a platform that allows building serverless applications using MongoDB as the database with features like serverless functions and mobile sync capabilities.
