Bank of Anthos is a sample HTTP-based web app that simulates a bank's payment processing network, allowing users to create artificial bank accounts and complete transactions.
This fork modifies the original Bank of Anthos into a multi-repository microservices design to demonstrate how to integrate with skaffold's remote config dependency feature.

| frontend | Python | Exposes an HTTP server to serve the website. Contains login page, signup page, and home page. |
| ledger-writer | Java | Accepts and validates incoming transactions before writing them to the ledger. |
| balance-reader | Java | Provides efficient readable cache of user balances, as read from ledger-db. |
| transaction-history | Java | Provides efficient readable cache of past transactions, as read from ledger-db. |
| ledger-db | PostgreSQL | Ledger of all transactions. Option to pre-populate with transactions for demo users. |
| user-service | Python | Manages user accounts and authentication. Signs JWTs used for authentication by other services. |
| contacts | Python | Stores list of other accounts associated with a user. Used for drop down in "Send Payment" and "Deposit" forms. |
