How pedrobubuli/tp2_arqui_publico works

This repository migrates an arVault currency-exchange service to Azure. A client sends an exchange request with a DNI; the API validates the request, the exchange logic checks the rate and accounts, consults ARCA, reserves funds and performs transfers, then records the outcome in shared Redis. The graph also shows account/rate management and the documented Azure deployment pieces. Runtime calls are grounded in the sampled Node files; infrastructure relationships are documented in the README, but the Terraform and Ansible sources were not sampled.
