Previously in this series, you deploy a simple workflow for processing image uploads in the Happy Path web application. In this post, you add progressively more complex functionality by deploying new versions of workflows.

This post focuses on the business logic layer of the Happy Path application. I introduce Step Functions and show how you can use Amazon States Languages (ASL) to define state machines.

In part 2, I cover the API configuration, geohashing algorithm, and real-time messaging architecture used in the Ask Around Me web application. These are needed for receiving and processing questions and answers, and sending results back to users in real time. In this post, I explain the backend processing architecture, how data is aggregated, and […]

This post explores the backend architecture of the Ask Around Me application. I compare the cost and features in deciding between REST APIs and HTTP APIs in API Gateway. I introduce geohashing and the npm library used to handle geo-location queries in DynamoDB. And I show how you can build real-time messaging into your web applications using the publish-subscribe pattern with AWS IoT Core.

In this post, I introduce the Ask Around Me example web application. Learn to build a serverless realtime, Vue.js web app in part 1 of this series.
