git clone https://github.com/Sreenivas-Sadhu-Prabhakara/sd-bulk-payments
mvn -f sd-bulk-payments spring-boot:run
curl localhost:8080/v1/service-domain
# or deploy onto Kubernetes (Cilium eBPF mesh)
helm upgrade --install sd-bulk-payments ./helm -n bian-operations
FAQQuestions
What is the BIAN “Process” functional pattern?
A Process service domain executes and tracks a defined operational procedure, step by step, to completion. Bulk Payments applies it to the Bulk Payment File.
What is a BIAN service domain?
BIAN (the Banking Industry Architecture Network) decomposes a bank into independent service domains, each owning exactly one business capability. Bulk Payments is the service domain for Payments; it manages the Bulk Payment File Procedure and exposes it through standard BIAN action terms.
What business area does Bulk Payments belong to?
Bulk Payments sits in the Operations and Execution business area — the operational core that executes payments, positions, settlements and transactions. It runs in the bian-operations namespace as one independent Spring Boot microservice.
Is Bulk Payments production-ready?
It is an educational reference implementation: a real BIAN REST API over an in-memory store, ready to be filled with domain logic. It is not a live bank and is not affiliated with BIAN.
