I was searching for an AWS-native solution that would deploy resources via Terraform, allow them to do some work, and then destroy them properly without leaving any orphaned resources. Also, multiple of those Terraform deployments needed to be live at the same time. The solution I found is a combination of AWS CodeBuild, AWS Step Functions, a Terraform State being managed in S3 and Terraform Workspaces.

Update 2024: QLDB will be discontinued in mid 2025, don’t use it for new projects. This blog introduces you to a database that solves an interesting niche problem: Amazon Quantum Ledger Database (QLDB). We’ll get to the service later, but first, I’m going to set the stage by describing a problem that the service can solve. I’m going to tell you a story - not my own story but one that happened to a colleague.

One of the less pleasant aspects of working with AWS using Python is the fact that most IDEs aren’t able to natively support Autocomplete or IntelliSense for the AWS SDK for Python (boto3) because of the way boto3 is implemented. Today I’m going to show you how easy it has become to enable Autocomplete for boto3 in VSCode. Before we come to the solution, let’s talk about why native Autocomplete doesn’t work with boto3.

Testing is one of the most critical activities in software development and using third-party APIs like DynamoDB in your code comes with challenges when writing tests. Today, I’ll show you how you can start writing tests for code that accesses DynamoDB from Python.

In this blog, I take you along on my journey to build my first Golang-based Lambda function. Inspired by surprise on my RDS bill, I built a Lambda function in Go to periodically stop running databases with a specific tag. Come, learn and debug with me!

We can use permissions boundaries to give developers and teams more freedom to create their own resources. For forcing them to provide specific tags during resource creation, we need a deeper understanding of how this can be achieved. We talk about the example of creating a security group.

There is a conflict between developer freedom and the requirements of security teams. In this post we’ll look at one approach to address this tension: permission boundaries. They’re an often overlooked part of IAM, but provide a valuable addition to our security toolkit.

MQTT is one of the core protocols that enables IoT applications. In this post we’ll first introduce MQTT and some of the core concepts. We’ll also take a look at AWS IoT Core, the MQTT broker that comes bundled in AWS.
