8. Case Study: Debian at Microsoft
APT is (possibly) the most prevalent package manager in the
Microsoftecosystem
Microsoft distributes software for Debian
Microsoft runs Debian for top-of-rack networking in all datacenters
Microsoft runs Debian (on Azure) for all the Skype relays
Microsoft builds a minimal set of Debian packages for reproducibility

Observability (book)
"[…] I tried all of these tools and more, and none of them helped resolve system
performance and reliability. Let me repeat: none of them did what they claimed to
do. This isn’t because they lied or misrepresented themselves, it’s because the
kinds of systems we were building were fundamentally different than the
systems those tools were developed to understand. Parse was an early adopter
of a lot of trends which are still relatively cutting edge, and more and more people
are now experiencing the consternation and frustration that I did during that time.
These older tools, once revolutionary, simply no longer work for our current
systems." - Charity Majors
