USEWhat it is used for

Representative use cases for the Enterprise Architecture service domain within a BIAN-aligned core-banking landscape.

APIBIAN semantic API

The control record (Architecture Blueprint Design) is exposed through uniform BIAN action terms. Java 21 · Spring Boot 3, OpenAPI at /swagger-ui.html, health at /actuator/health.

RUNRun it yourself

Each service domain is its own standalone Spring Boot repository — clone and run in seconds, or deploy onto Kubernetes with the bundled Helm chart behind the Cilium mesh.

# run this service domain standalone
git clone https://github.com/Sreenivas-Sadhu-Prabhakara/sd-enterprise-architecture
mvn -f sd-enterprise-architecture spring-boot:run
curl localhost:8080/v1/service-domain

# or deploy onto Kubernetes (Cilium eBPF mesh)
helm upgrade --install sd-enterprise-architecture ./helm -n bian-business-support

FAQQuestions

What is the BIAN “Design” functional pattern?
A Design service domain develops and maintains the definition of products, models or configurations used elsewhere. Enterprise Architecture applies it to the Architecture Blueprint.
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. Enterprise Architecture is the service domain for Business Command and Control; it manages the Architecture Blueprint Design and exposes it through standard BIAN action terms.
What business area does Enterprise Architecture belong to?
Enterprise Architecture sits in the Business Support business area — the shared corporate, finance and technology domains that run the bank itself. It runs in the bian-business-support namespace as one independent Spring Boot microservice.
Is Enterprise Architecture 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.
