⬅️ Definitely programmer's nightmare, huh? 👻
Legacy systems are difficult to modify, slow down business development, and create high IT risks. At the same time, due to their historical nature, they are extremely hard to replace, as doing so would essentially mean rebuilding the business logic from scratch.
As a result of many years of development, the business logic of these systems has become a large, tangled mess of functionalities.
The legacy database code of large companies often consists of thousands of SQL procedures, chaotically connected by calls to each other (yes, we know how to build such maps)
"LegacyTopology" is frameworks to migrate business logic from SQL procedures to Java microservices
We understand the technological specifics of this sophisticated process and create the

Here are five strong reasons to move from Legacy SQL to a microservices-based, open-source modern stack:
- Scalability & Flexibility. Microservices allow you to scale individual components independently based on load, unlike monolithic Legacy SQL systems that can become bottlenecks as demands grow.
- Faster Development & Deployment. With services decoupled, teams can develop, test, and deploy independently, enabling continuous delivery and faster innovation.
- Technology Agility. A microservices architecture allows you to choose the best open-source tools or languages for each service (e.g., PostgreSQL for OLTP, Apache Kafka for streaming), instead of being locked into one SQL engine.
- Improved Fault Isolation. Failures in one microservice do not bring down the entire system. This improves reliability and makes troubleshooting and maintenance easier.
- Cost-Effectiveness & Community Support. Open-source tools reduce licensing costs and offer a vibrant community for support, plugins, and rapid issue resolution—unlike many proprietary Legacy SQL solutions with vendor lock-in.
Your code is not transferred anywhere. The "LegacyTopology" software complexes are fully autonomous within the internal network, have no external servers for communication, and therefore do not require Internet access. Moreover, for additional protection of the codebase, we recommend installing our solution on virtual hosts that have no Internet access. The only required network activity is user authentication via SSO Keycloak within the internal network.
