The reasoning often sounds solid on the surface, but it usually lacks depth. These decisions are rarely based on actual system needs or team constraints. Instead, they are driven by assumptions that don’t hold up in practice. Let’s examine the most common ones. #1 Microservices Will Make My App Scalable Many developers believe that adopting microservices will automatically make their system scalable. This assumption is misleading. Scalability is not a direct result of splitting an application into services. A well-structured monolith can scale effectively using horizontal scaling, caching, and datab
