Amazon Web Services is always changing. New features are added and new services are launched all the time. But during re:Invent – the annual AWS conference – a flood of news is poured out on us. Some news will change the way we architect cloud-native applications today or in the coming months. While other news is irrelevant to us.
AWS provides many building blocks. As architects, we have to choose the right building blocks to construct our systems. But sometimes, the proper building block is not available, and we have to make compromises. In this blog post, I show four unusual AWS architectures that deal with AWS’s limitations in creative ways.continue reading
A document-oriented database stores keys mapped to JSON documents. You can query all documents in such a document-oriented database and retrieve only parts of documents to save network bandwidth.continue reading
Previously, I compared all database options offered by AWS for you. In this post, I compare the available messaging options. The goal of messaging on AWS is to decouple the producers of messages from consumers.
The messaging pattern allows us to process the messages asynchronously. This has several advantages. You can roll out a new version of consumers of messages while the producers can continue to send new messages at full speed. You can also scale the consumers independently from the producers. You get some kind of buffer in your system that can absorb spikes without overloading it.
In this blog post, I introduce all the messaging options that AWS offers. Afterward, I end with a comparison table of the options.continue reading
Andy Jassy, CEO of AWS, proclaimed #DBFreedom, aka use whatever database you like. AWS offers them all. At least, that’s what AWS marketing wants us to understand.continue reading
Despite the Kubernetes and Serverless hypes, the vast majority of cloud workloads still happen on virtual machines. AWS offers the Amazon Elastic Compute Cloud (EC2) service, where you can launch virtual machines (AWS calls them instances). The EC2 service has evolved over 13 years. More performance, lower and less volatile latencies, and easier management are just some of the innovations of the last years. This blog post demonstrates how you can build modern architectures on EC2 and comes with ten tips to avoid the common pitfalls.continue reading
