Transactions in a Microservice World

Typically, microservice-based applications distribute data widely, especially in cloud-based applications, resulting in distributed applications. This impacts the transactions within these applications. This white paper refreshes the concepts of classical and distributed transactions. Next, we explain how cloud-based applications are affected by distribution. Finally, we present compensation-based transactions as a reliable method for microservice-based application transactions, even in the cloud.

Bare-metal Kubernetes

I've been running a Kubernetes cluster on a mix of virtual and bare metal machines with Hetzner for about a year now, and while the setup has served me well, being a very exploratory exercise at the time it wasn't very well documented.

To rectify this, and to get a chance to play with some tools I wasn't aware of at the time, I've decided to rebuild the cluster from scratch and document the process through these posts.
