#022: Monorepos: The Good and Bad

📚 ABOUT THE EPISODE

In the 21th episode Grzegorz Godlewski and Artur Wolny share their negative experiences with implementing Microservices. Three examples of misuse of that useful pattern shows us that even the greatest idea can lead us down the blind alley, when we are narrow-minded about it.

📑 TOPICS COVERED

👉 Impact of blindly following recommendations: costly premature optimisations.
👉 Thing that might go wrong when you're focused too much on domain assignment of feature and too less on the app maintainability.
👉 How microservice hype-trains and poor organisational decisions lead to project failure.

00:02:08 - Story #1: Blindly following recommendations.
