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!

Amazon Ion is one of the data serialization formats you can use when exporting data from DynamoDB to S3. Recently, I tried to select data from one of these exports with Athena after using a Glue Crawler to create the schema and table. It didn’t work, and I got a weird error message. In this post, I’ll show you how to fix that problem. If you’re not familiar with Ion yet, check out my recent blog post introducing it for more details.
Amazon Ion is a data serialization format that was open-sourced by Amazon in 2016 and is used internally at the company. Over time it has also been introduced into some AWS services and is the data format that services like the Quantum Ledger Database (QLDB) use. It has also started to appear in more commonly used services, so I think it’s worth taking a closer look at. This article will explain what Ion is, its benefits, and how you can use it in Python.
Recently, I spent a lot of time using the exciting new member of the FSx family. One detail made working with it a bit unpleasant, though - the lack of log files. This post details how to create a custom integration into CloudWatch Logs and make ONTAP audit logs visible.
Lambda destinations enable you to respond to successful or failed asynchronous invocations in a way that wasn’t possible before the feature was added. I explain what this feature allows you to do and show you how to use it.
The project steampipe uses a fast programing language and an intelligent caching approach outrunning prowler speed tenfold. While I tried to workaround prowlers limits I learned a lot about optimizing.
Apache Airflow doesn’t only have a cool name; it’s also a powerful workflow orchestration tool that you can use as Managed Workflows for Apache Airflow (MWAA) on AWS. This post will explain which problems the service solves, how you can get started, and the most important concepts you need to understand.
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.
