Microservices: When to Split and When to Keep It Simple

Microservices have become the buzzword of modern software architecture, promising better scalability, team autonomy, and technology diversity. However, they also introduce significant complexity in terms of deployment, monitoring, and inter-service communication.

The decision to adopt microservices shouldn't be taken lightly. They work best when you have clear service boundaries, independent teams, and the operational maturity to handle distributed systems. If you're a small team working on a new product, starting with a well-structured monolith is often the better choice. You can always extract services later when you understand your domain better.

When you do decide to go with microservices, focus on getting the basics right: service discovery, load balancing, circuit breakers, and comprehensive monitoring. Each service should own its data, have clear APIs, and be deployable independently. Remember that microservices are a tool for solving organizational and scaling problems, not technical ones. If your main goal is just to use the latest technology, you might be solving the wrong problem.
