How to Avoid Coupling in Microservices Design by Mariam Rajabi
How can we avoid distributed monoliths and build microservices that are truly loosely coupled? In this article, Capital One Senior Software Engineer Mariam Rajabi covers how to minimize implementation coupling, temporal coupling, and deployment coupling in your microservices design.
Two systems are loosely coupled if changes to the design, implementation, or behavior in one won’t cause changes in another. When it comes to microservices, coupling can happen if a change to one microservice enforces an almost immediate change to all other microservices that collaborate with it directly or indirectly.

Ah, So That’s What’s in My Wallet by Sahana Arya and Alana Alfeche
We love when our work resonates with our readers and they hit that social share button on our content. Our most shared article of 2021 was an explainer on the EMV chip inside your credit card.
Like many others at Capital One, we know what needs to be done to support credit card initiatives, but we were curious about how physical credit cards actually work! Our curiosity propelled us to dig deeper and learn more about this technology. We were fascinated by what we learned about physical credit card technology and figured other software engineers would be interested in learning the same.
Shared almost 300 times on Twitter and LinkedIn, it seems that many of you were equally curious about this credit card chip technology!
