Have you worked only with one service or interacted with multiple?

In my practice, I have interacted with both a single service and multiple services simultaneously. Working with a single service is usually simpler and focuses on a specific task, such as data retrieval or executing certain business logic.

Interacting with multiple services requires coordination between them, error handling, and data synchronization. For example, in a Java application, you can use several REST services to obtain different data, combining their results for display to the user.

This approach is often seen in microservices architecture, where each service is responsible for its part of the functionality, and the application interacts with them via APIs.
