When you speak with software developers, they will probably tell you that they use design patterns. But when the world first shifted to the internet the general feeling was that these design patterns would not work for the web. This is not true, and today you see these patterns being used more and more.

As a consultant I am used to a certain level of quality that I need to deliver to our customers. For this reason I have built a landing zone for my own website, initiatives and experiments. By using the same structure that our customers have, I can test and build my ideas and apply them in customer environments if they are successful.

In one of my previous blogs I wrote why I switched to compiled languages for my lambda functions. But using Golang for your lambda functions does add some challenges. In this blog I would like to share the challenges that I have seen and how to mitigate them.

When you start working with AWS one of the easiest ways to interact with the APIs is through the IAM User. Although it’s not the advised way it’s the easiest way hence the most used one and the most abused one. In this blog I will dive a little deeper into this topic.

I recently switched to Golang for my language of choice. (In my previous blog you can read why.) But I am also a big fan of test driven development. With Python you have a stubber that helps you mock the AWS API. So how do you do this in Golang? I found 2 ways to do this. One via dependency injection and one via a stubber. In this blog I will share my experience so far.

I was sparked on a XKE to do a short experiment with using Golang for my AWS Lambda Functions. The trigger for this was something my colleague Mark van Holsteijn said. We where talking about sustainability. During this talk Mark made the comment that we should drop Python for our functions then. (He also recently wrote a blog on Golang using Golang for custom providers.)

Hugo is a great tool that let you build website fast and easy. It will render a complete static HTML version of your website. This makes it an ideal candidate to host it on a S3 Bucket. You can then use CloudFront to serve the content across the globe.

Managing more than one AWS accounts can become challenging. AWS Organizations provides a way to manage many accounts. You can automate account creation and management. If you use a naming schema you can leverage landingzone-organization! 

Use StepFunctions to simplify your serverless applications

AWS StepFunctions is a great orchestrating tool for your serverless applications. When you write lambda functions that only contain logic to perform a single task they are easier to test. Especially when there is no orchestration logic within your function.
