When implementing REST APIs in AWS there is one service that always comes to mind - Amazon API Gateway. Even though feature-rich, properly documenting your API may become a time-consuming task relatively quickly. In this post, I would like to show you how you can use Swagger UI in combination with a serverless deployment to automatically generate interactive and up-to-date documentation for your APIs.

AWS BI Solution Amazon QuickSight is a powerful tool to build interactive analyses or dashboards. In this blog post we will see how to get started with designing such analyses.

When you start out learning about S3, the experts and documentation will tell you that you should think of S3 as a flat key-value store that doesn’t have any hierarchical structure. Then you go ahead and create your first S3 bucket in the console, and what the interface shows you is a nice big “Create Folder” button. You may be justifiably confused - didn’t I just learn that there are no folders, directories, or hierarchy in S3?

In modern architectures, Lambda functions co-exist with containers. Cloud Native Observability is achieved with open telemetry. I show you how to send open telemetry traces from Lambda to a Jaeger tracing server. Let’s see how this compares to the X-Ray tracing service.

SAP systems running in a distributed environment have certain requirements regarding how to set the hostname and how those need to be resolved from other hosts. In our test landscape we use virtual hostnames to decouple the SAP instances from the underlying hardware which is running on a Red Hat Linux Server. This blog post will walk you through the components in AWS that fullfil those requirements and allow SAP instances to communicate while keeping administrative effort super low.

We know how to follow traces with the X-Ray SDK. Now there is AWS Distro for OpenTelemetry claiming to do this better. Let’s build CDK examples for Lambda with TypeScript/Python/Go and find out who is the better spy in this game.

There are several ways to perform espionage activities in the life of a serverless app, which all battle for your attention. Time for the advent of counterintelligence: We want answers! - And CDK/Source examples of how to use it! Here we go, Serverless spy vs spy in four chapters, each post published after you light the next candle.

There is no (milli)second chance for the first impression. Many websites today mess this up badly. When I need to wait 10 seconds for the content to load - I am out. What about you? I show you how to optimize the speed in four steps with S3, CloudFront and Amplify.
