Feature Flags Book: Logs, Metrics, And Feature Flags

In the early days of my career, my error-handling approach consisted of catching errors and then sending myself individual emails containing the error details. This was OK initially; but, it didn't scale well. Which I learned the hard way one morning when I arrived at my desk and found over 47,000 errors in my Inbox (due to a failing database connection).

Eventually, I learned about error logging and log aggregation services. And, suddenly, the idea of emailing myself an error message felt so naive and antiquated. The more I used logs, the more I came to realize just how powerful they were. And, soon thereafter, I started to view logging as a critical component in my application architecture.

In 2023, I published a book titled, "Feature Flags: Transform Your Product Development Workflow". This book contains everything that I've learned over the last 7 years about integrating feature flags into my product development. But, a static book can only take you so far. In an effort to make the book more interactive, I've created a series of blog posts—one per chapter—that provide a place in which the readers and I can discuss the content. You can purchase the book and / or read a preview of each chapter on the book's mini-site. Feel free to leave a question or a comment down below.
