Transforming large amounts of data into formats that help solve business problems is what data engineers excel at. A combination of Serverless tools such as Athena, StepFunctions, Lambda, or Glue can get the job done in many projects. However, some customers prefer to rely on Open-Source projects and tools to access more talent in the job market and be less reliant on a single cloud provider. Today, we’ll share a story of a modernization project that we did for a customer in the online marketing industry.

Even when safely storing your MFA tokens using the Token2 Molto-2 device, some things are not quite optimal. You have to use special Windows-only software to program new accounts, it is not PIN-protected, and things could be better in terms of usability. If you have a bit more of a budget, the Reiner SCT tanJack Deluxe might solve your problems. Let’s have a look at this device.

Everybody knows you should protect your AWS accounts (and other logins) with MFA against brute-force attacks. Most of the account providers use a standardized algorithm (RFC 6238) to generate the famous six-digit TOTP codes for your login. But where do you store those securely? Today, we will look at the alternatives and a specific device: The Molto-2.

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.

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. That story made me understand where QLDB-like systems could be beneficial.

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!
