This is part 4 in the series of BareMetal-as-a-Service with Ironic. In this article I will focus on highly distributed architectures. Baremetal cloud as a service for the edge and large environments.<\/p>\n\n\n\n

What would be a good use of this architecture? I can think of few examples:<\/p>\n\n\n\n

– managing lifecycle of hundreds of individual x86 servers monitoring production of the goods in manufacturing industry <\/p>\n\n\n\n

– almost any x86 based IOT use case<\/p>\n\n\n\n

– managing highly distributed infrastructure sitting in stores for the large retailers<\/p>\n\n\n\n

– managing unreleased server equipment directly at the desks of the engineers <wink><\/p>\n\n\n\n

– running distributed kubernetes clusters<\/p>\n\n\n\n

I have meant to document this use case long time ago, since I had it working since OpenStack Queens (OSP13) but I didn’t get to it until now (Train – OSP16.1). This is probably the least documented functionality of Ironic\/Neutron. At the same time solves problems of managing any workload on baremetal at the edge (or just distributed over multiple L3 networks for better resiliency).<\/p>\n\n\n\n

Here is a quick demo on how it works in practice: https:\/\/www.youtube.com\/embed\/yM8P5TOr1hE<\/p>\n\n\n\n

The diagram above describes a high level architecture of my lab, but here are 2 more pieces of information that might be helpful to understand the configs listed below:<\/p>\n\n\n\n
