Resilience Patterns Can Make Your System Less Resilient

You wanted your system to be resilient, so you followed the standard advice. You added retries.You added circuit breakers.You added fallbacks. But now your system is less resilient. Not because those patterns are bad. They are not. The problem is they are doing exactly what you told them to do. YouTube Check out my YouTube channel, where I post all kinds of content on Software Architecture & Design, including this video showing everything in this post. Retries are great for network blips and transient issues. But the tradeoff is that you are adding more load to a system that might already be… Read More »Resilience Patterns Can Make Your System Less Resilient

Modular Monolith Boundaries Done Wrong

So you built a modular monolith. You have a clean structure. Different projects. Everything broken into modules. But somehow, when you make a change, it still ripples through the rest of your system. Why? Because its highly coupled. YouTube Check out my YouTube channel, where I post all kinds of content on Software Architecture & Design, including this video showing everything in this post. As an example, let’s say you have an HR module. You change an employee’s work status, and all of a sudden, that affects authentication. Or you’re in a transportation system, and you change a vehicle’s compliance status, and… Read More »Modular Monolith Boundaries Done Wrong

Scaling Software Architecture Without Overengineering

Your system has 500 users and also has 20 microservices, including the gauntlet of Kubernetes, a message broker, distributed tracing, multiple different databases, and a pretty dashboard that probably nobody looks at. Someone will ask the question: why is this so complicated for 500 users? And usually the answer is, “Well, we’re building for scale.” No. No, you’re not. You’re building for scale you don’t have yet. That’s a lot of extra complexity. Scaling software architecture is important to think about. But there’s a difference between actually implementing for scale and giving yourself the options to scale when you need… Read More »Scaling Software Architecture Without Overengineering
