The architecture is: While the bpftrace binary is installed on all the target systems, the bpftrace tools (text files) live on a web server and are pushed out when needed. This is thinking like a sysadmin who installs and maintains software, and not like a programmer who codes everything. That will be a quick and useful version 1.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory.

Developing machine learning models is no different from developing traditional software, in the sense that it is also a full life cycle involving design, implementation, tuning, testing, and deployment. ci can integrate with an existing CI server (Travis in the implementation), and provides a DSL for specifying model tests.
