“Platform Engineering is reshaping how software is built. Most guidance available is too abstract to act on.”
No clear standards
The discipline is evolving fast and fragmented across vendors, tools, and communities.
Conflicting advice
What works at a FAANG company rarely applies to a 50-person engineering team.
Theory without practice
Most resources stop at the why — this book is focused entirely on the how.
