Organizing AWS microservices with Python, Serverless, and namespace packages

Our project began with a small ask: build a small Python back-end using AWS Lambda and API Gateway (with just a handful of endpoints to support a few pages) and use Serverless [https://serverless.com/] to manage the Cloud Formation setup. Not very involved, not much code, not even much configuration for the deploy. Next came authentication. In pursuing the joint dreams of DRTW ("don't reinvent the wheel") and WALCAP ("write as little code as possible"), we selected AWS Cognito over other opti

Consequently, apps have access to a great deal of information about our preferences, our contacts, where we go, what we buy, and who we are. As app developers, we need to be cognizant of the information being handled by our apps and to safeguard it accordingly. The protection of sensitive information is

State of Swift WebSockets

Apple delivered several exciting and innovative new APIs for developers at WWDC this year. You might have heard or read about the SwiftUI and Combine revamp, but I want to address the new world of native WebSockets! The historically complicated connection protocol is now delivered as a first class citizen! Before we dive in on how awesome this is, it's important to have a basic understanding of Sockets and the road we've traveled to reach this point. What is a socket? By definition a socket is

Deploying a WebSocket Application on Beanstalk

So, you are about to build a new app and you need at least part of it to update in real-time. Well, we live in a modern world so it’s pretty common to have at least a part of the app update without requiring a user interaction or a page (re)load.
