Answer
To maintain service independence and scalability.
Using SQL JOINs across services creates interdependencies that can lead to performance bottlenecks and complex failure recovery. Instead, microservices should communicate through APIs. For example, instead of joining 'User' and 'Order' services directly in SQL, use an HTTP call to fetch user data when processing orders.
