Project Architecture
The project architecture represents a well-structured layout of different services communicating over the web. Imagine this architecture as a bustling marketplace, where each stall (service) specializes in a particular type of product or service. The stalls work independently yet collaboratively, sharing information seamlessly via well-defined pathways (APIs).

Troubleshooting
While implementing the REST microservices architecture, challenges can arise. Here are some common issues and their solutions:
- Problem: Services not communicating.
- Solution: Ensure your service configuration is correct, and that all service endpoints are reachable from one another.
- Problem: Data inconsistency.
- Solution: Utilize transactions carefully and check that your data repositories are correctly configured for either SQL or NoSQL data stores.
- Problem: Load Issues.
- Solution: Consider adding a load balancer like Netflix Ribbon and ensure instances are scalable.
