a Finnish security engineer, a Swedish datacenter engineer, and myself built a self-hosted continuous deployment system that is built around a blue-green deployment strategy. (Inspired by AWS internal systems) we wanted a system that can integrate with any cloud service, VM provider, and/or bare metal.

We built this together at a previous organisation and moved all the internal and external services at that organisation to this system (It allowed the org to satisfy the ISO27001 requirements).

After being in operation for a couple of years, we have collected a lot of insights and feedback on what to change/improve for the open source version.

This summer I’m setting aside some time to work on making those changes for an open source version of what we call “Vanir”.

(Seems like good timing with the initiatives in EU to take back some ownership of the cloud stack).

No LLM or AI magic. Just simple state machines, extendable configuration, and a lovely GUI (web-based, no JavaScript).

The tech stack is python3, postgresql, ansible, and django.
