Introduction In the world of IoT, managing and accessing data from various sensors efficiently is crucial. AWS provides a powerful suite of tools that allow developers to seamlessly integrate IoT devices, store data, and expose this data via RESTful APIs. In this post, we will walk through how to...

Integration testing for serverless Event-Driven Architecture is as necessary as it is time-consuming. Boilerplate code to write, long waiting for tests completion, tedious debugging. But no more.

I recently created a CDK library provisioning a CI/CD pipeline for serverless apps on AWS. Having finished the "regular" JS library, it took me a day to convert it to a "proper" CDK Construct library. Not long, and I learned a lot. Here are my thoughts and tips.

CDK generates Logical IDs used by the CloudFormation to track and identify resources. In this post, I'll explain what Logical IDs are, how they're generated, and why they're important. Understanding this will help you avoid unexpected resource deletions and baffling "resource already exists"...

Yes, you can run Machine Learning models on serverless, directly with AWS Lambda. I know because I built and productionized such solutions. It's not complicated, but there are a few things to be aware of. I explain them in this in-depth tutorial, where we build a serverless ML pipeline.

Security is not convenient. That's probably why the CDK, by default, uses AdministratorAccess Policy to deploy resources. But we can easily change it and increase the security of our AWS account, following the least privilege principle with a minimal additional burden.

Until recently, I was skeptical about the AWS CDK. I believe in Infrastructure as Code (IaC), but with the "code" being YAML. But after using CDK in real projects, the amount of heavy lifting it does and the vast reduction of a boilerplate code changed my view.
