Last job we used a former game dev to create a single executable combining an ffmpeg core, an SQLite manager, REST server, a facial recognition engine, and an notifications push server into a single high compute executable. Considering the number of OS services such a Swiss army knife application requires, would such be appropriate for a unikernel, as a single app? Reason being, when combining all those aspects, huge optimizations become available that are simply not possible when the work is spread across even multiple executables.
