Microservices or Monolith: Which is Better for Precision Engineering Software?

Honestly, if your software runs on a single machine, go for a monolith. Microservices aren't the solution until you're sure they are necessary.

Microservices can fix organizational issues, especially if you have multiple teams working on different features. It allows each team to ship independently, but it's not the cure-all for technical problems.

Start with a monolith! It's usually easier and gives you the chance to collect metrics on how your system is performing before you decide to break anything out into microservices.

The reason for choosing an architecture should focus on system load and your specific requirements, not just whether the system should be high or low precision. A modular-monolith is a safe bet, allowing for future scalability if needed.

A hybrid approach could work well—something like a basic n-tier system. That way, if you make changes to one component, it doesn’t drastically affect the others. It's all about your needs for scalability and reliability.
