Distributed applications Distributed applications have many definitions, but typically they are defined as applications that run on a network of multiple computers. Nowadays, that might well mean an application that runs on multiple Kubernetes clusters that are distributed over a large geographical area. Since such clusters are distributed, they have many benefits - like high-availability, speed, resiliency - but it can make developing, operating, and testing such applications tedious. The Multi-DC feature of Bank-Vaults is just such a distributed application; its testing was not automated and required us to manually test each time an important PR went into master.

If you are a frequent reader of this blog or familiar with our products, you may already be aware that the control plane of our multi- and hybrid-cloud container management platform, Pipeline, is available not just as a free/developer service but can be run in any number of preferred envionments, whether cloud or on-prem. The control-plane’s only requirement is Kubernetes, its installation wholely automated by the banzai CLI tool alongside our own CNCF certified Kubernetes distribution, PKE.
