Feature Flags Book: Bridging The Sophistication Gap

By on

As you read through the use cases chapter, it may have occur to you that large, sophisticated companies have different ways of solving the same problems. For example, instead of using feature flags to implement rate limiting, a more sophisticated company might put that logic in an Application Load Balancer or a reverse proxy.

Or, instead of using feature flags to implement IP-blocking, a more sophisticated company might add reactive request filtering to a Web Application Firewall or dynamically update ingress routing rules.

Or, instead of gating code behind a feature flag, a more sophisticated company might adjust the traffic distribution across an array of Blue/Green deployment environments.


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.

I believe in love. I believe in compassion. I believe in human rights. I believe that we can afford to give more of these gifts to the world around us because it costs us nothing to be decent and kind and understanding. And, I want you to know that when you land on this site, you are accepted for who you are, no matter how you identify, what truths you live, or whatever kind of goofy shit makes you feel alive! Rock on with your bad self!
