What is SpringBank?

It is a Spring Boot-based microservices demo for a banking application. It simulates common banking operations such as login, logout, account management, and transaction history using Spring Cloud's service registry and REST APIs.

Primary Goals:

• Show how a Java EE monolith can be broken into microservices
• Demonstrate service discovery using Netflix Eureka
• Provide a REST-based backend (does not include a frontend UI)
• Serve as a backend prototype for a banking web or mobile app
