InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
https://www.kernel.org/doc/Documentation/arm64/booting.rst This was my guiding light for a project a while back. It describes what Linux expects "time zero" looks like for the system; whatever operating system is going to boot needs that kind of contract between the boot environment and its own entry point. You can develop a lightweight linux-based OS with that document and a package like https://busybox.net/
