Migrating workloads into the cloud — and specifically to AWS — comes with many advantages. You can operate workloads in new ways. When you only pay for what you use and add capacity within minutes, the world of auto-scaling opens up.continue reading
Scheduled batch jobs are the heart of many business processes implemented by enterprise applications. Reports are generated daily, databases are optimized over the weekend, and business logic is executed nightly. The importance of batch jobs satisfies an investment into a reliable architecture to execute the jobs.continue reading
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
