## Overview

EazyBank is a microservices banking application with account, card, and loan capabilities, plus gateway, configuration, discovery, and messaging services. The visible user workflow enters through Accounts APIs: customers can create, fetch, update, or delete accounts; a separate customer-details endpoint gathers account, card, and loan data. Account creation persists customer and account records and emits a communication request. Card and loan services provide their own domain capabilities. Source excerpts support several internal calls, but gateway routing, service registration, and message-consumer wiring are not shown, so those relationships are omitted.
