Customize a Cognito Access Token with Rust

Posted on December 29, 2023by Benjamen Pyle

Identity and Access Management is a critical part of any application. And having a solution that provides customization can also be super important. Take for instance the ability to customize a Cognito Access token to extend functionality.

So many times developers and architects try and roll their own solution and while they do their best to meet OAuth and OIDC specifications, they just tend to fall short. Not to mention they end up with more maintenance and scaling issues than they planned. By leveraging a Serverless Identity Platform like Cognito, developers and architects gain a piece that takes care of the heavy lifting of identity and access for a user base of 1 to essentially as many as needed.

However, until very recently a gap in functionality that honestly allowed some insecure usage existed. Developers were using ID tokens as Access tokens because only those tokens could be customized within a Cognito sign-in workflow. That is no longer the case, as Access tokens can now be customized. I want to take a look at how to customize a Cognito Access Token with Rust.

Web API with Rust and Fargate

Posted on December 21, 2023by Benjamen Pyle

I’ve been spending more and more time with Rust which is perfectly in line with my end-of-year planning. So far, my collection of articles is growing and so are my Rust skills. I can’t profess to be more than a novice at this point, but when has that stopped me from crafting something meaningful around a piece of technology? I hope you find this entry helpful and insightful as I dive into building a Web API with Rust and Fargate.

API Gateway, Lambda, DynamoDB and Rust

Posted on December 5, 2023by Benjamen Pyle

It’s been a few weeks since I last wrote an article on using Rust with AWS. In the span of then and now, AWS officially released their Rust SDK for interacting with many of their services. If there was a barrier before this in my mind about using something in production that wasn’t generally available, that barrier is now gone. I also made a public commitment to building more examples in Rust in 2024 and while I’m a few weeks early, I just can’t contain my enthusiasm for learning this language that feels nothing like anything I’ve worked with before. Let’s take a look at building an API with API Gateway, Lambda, DynamoDB and Rust.

Consuming an SQS Event with Lambda and Rust

Posted on November 3, 2023by Benjamen Pyle

I’ve been trying to learn Rust for the better part of this year. My curiosity peaked a few years back when I learned the AWS-led Firecracker was developed with the language. And I’ve continued to want to learn it ever since. Fast-forward and I’m jumping both feet in. That’s usually how I work. I must admit that right now, I’m the most noob of noobs, but that’s not going to keep me from sharing what I’m up to and what I’m learning. For me, this blog is as much about sharing as it is about learning and communicating to those reading that it’s OK to be where you are in your journey. There are no straight lines. Only periods of growth and plateaus. In this article, I’ll walk you through consuming an SQS Event with Lambda and Rust.
