We’ve completely revised one of our most popular free ebooks, How to Architect and Build Highly Observable Systems
. This book, originally written in 2015, has been downloaded by thousands of visitors and has generated extensive discussion. The updated 2019 edition incorporates many of the great points our readers have raised, as well as reflecting the fast-evolving state of the observability community and industry, which is much different now than it was a few years ago.
Topics in the 2019 edition include observability tradeoffs, key signals to pick out of the noise, and making databases observable (including database-as-a-service such as Amazon RDS). This book is also information-dense: it’s a compact 20-page read, making it a must-have for anyone architecting systems that must be observable and understandable under heavy customer demand at scale!
