Servermeister migrated Mylette’s Bank Data Retrieval Connector (BDRC) for Hana Bank Amsterdam from an outdated Tomcat installation to a new, container-based on-premise environment. The BDRC links the bank to the Banking Data Referral Portal of the Ministry of Justice and Security.
from kick-off to operational API and dashboard
for API and dashboard, instead of a separate front and back end server
one point of contact between bank, head office in Korea, Mylette and Justid
As a bank in the Netherlands, Hana Bank is legally connected to the Banking Data Referral Portal. Through this portal, investigative and supervisory authorities automatically request customer and product data. Mylette’s BDRC answers these requests on behalf of the bank.
The existing BDRC ran on an older Tomcat installation with a separate front and backend server. Since version 3.1, Mylette only provides container images and no longer updates the Tomcat variant. Migrating was therefore not a choice, but a condition for remaining supported and safe.
The Amsterdam branch does not have its own IT department. There was no documentation of the network around the existing servers, and management was done via an unmanaged jump desktop. Mylette provides the software, but does not install and manage. Hana Bank was therefore looking for a party that could bear the full implementation.
The assignment was technically clear, but the preconditions were strict.
We are the point of contact between you, your suppliers and external parties.
Servermeister acted as the IT department that Hana Bank does not have locally: one point of contact between bank, supplier and ministry.
Joint session with Hana Bank and Mylette on assignment, purpose, preconditions and responsibilities, followed by a technical walkthrough of Mylette.
Survey of the existing servers and network, plus advice on power supply, UPS and cabling in the server room.
API and dashboard together on one Linux server instead of two, with the database on a separate Windows server. That saves hardware and management.
Placement of the servers, network configuration behind the FortiGate firewall, Ubuntu with Docker and nginx.
Windows Server 2025 with SQL Server 2025, an empty database with the correct collation and its own login. The API container builds the schema itself at the initial start.
BDRC API behind nginx, with the PKIoverheid certificate and mutual TLS towards Justice.
First validate the test port with the Ministry of Justice and the head office, only then the production port and the switch of DNS and NAT.
BDRC Dashboard rolled out with local users and roles.
A dedicated installation guide and defined launch scripts so that updates and recovery are reproducible.
The solution
Requests from the Justice Department arrive at nginx through the firewall. nginx handles the mutual-TLS connection with the PKIoverheid certificate and forwards the request to the BDRC API. API and dashboard share one database on a separate server; The dashboard is only available internally.
Hana Bank has a supported, documented BDRC environment with a dedicated point of contact for management.
BDRC 3.3.3 as a container, without its own maintenance of Java and Tomcat. Updates are the replacement of an image.
One application server instead of a separate front and back end server, plus a database server.
The API runs stably on the new database, the health check answers positively and the link is accessible from the outside with mutual TLS.
Compliance and management can see the status, the data provided and the request logs in the dashboard.
Certificate renewal, updates and network management are the responsibility of Servermeister, rather than a vendor that doesn’t consider it to be part of its scope.
