Rust and Lambda Performance

I made a statement on LinkedIn that if you have enough traffic hitting your Lambdas you might want to consider a different programming language. And if you’ve been reading my content lately, you won’t be surprised that I suggested Rust as that alternative. Some great conversation and questions ensued with one of them suggesting that it would be less elbow grease to stand up Kubernetes with some pods than to improve performance on Lambda. The number thrown out was 250ms at the p75 mark. Fortunately, I had just the workload to test this out. Yes, I already know the answer and you should too at this point. But let’s dig in to Rust and Lambda Performance.

Leveraging the SDK to Publish an Event to EventBridge with Lambda and Rust

Following up on my popular Rust and Lambda article, I wanted to explore how to put an event on an AWS EventBridge Bus. If you aren’t familiar with AWS’ EventBridge, think of it as a highly scalable Event Router with built-in scheduling and data transformation. Let’s take a deeper look at putting events on EventBridge with Lambda and Rust.

Serverless and Agile

Agile and Serverless go together like peanut butter and jelly. Ham and eggs. Coffee and creamer. Tea and milk. Name your favorite combination that resonates best in your head. But the truth is this, Agile and Serverless are a great pair when it comes to delivering value quickly to your customers and sets a foundation for adapting to change. And isn’t that the point?

Customize a Cognito Access Token with Rust

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.

AWS’ Cognito allows you to implement frictionless customer identity and access management that scales

Web API with Rust and Fargate

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

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.

Partitioned S3 Bucket from DynamoDB

I’ve been working recently with some data that doesn’t naturally fit into my AWS HealthLake datastore. I have some additional information captured in a DynamoDB table that would be useful to blend with HealthLake but on its own is not an FHIR resource. I pondered on this for a while and came up with the idea of piping DynamoDB stream changes to S3 so that I could then pick up with AWS Glue. In this article, I want to show you an approach to building a partitioned S3 bucket from DynamoDB. Refining that further with Glue jobs, tables and crawlers will come later.

Consuming an SQS Event with Lambda and Rust

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.

DynamoDB Incremental Export with Step Functions

When working on building solutions, the answer to some problems is often, it depends. For instance, if I need to deal with data as it changes and use DynamoDB, streams are the perfect feature to take advantage of. However, some data doesn’t need to be dealt with in real-time, once a day or every 30 minutes might be good enough. This was problematic up until recently, as AWS released incremental exports with DynamoDB. In this article, I want to explore building an incremental export with DynamoDB and Step Functions.

WebSocket with AWS API Gateway

I was working recently with some backend code and I needed to communicate the success or failure of the result back to my UI. I instantly knew that I needed to put together a WebSocket to handle this interaction between the backend and the front end. With all the Serverless and non-Serverless options out there though, which way do I go? How about plain old WebSockets with AWS API Gateway and Serverless?
