Community banks want to capture the youth market through platforms like REGO, but they fear that connecting a high-velocity mobile app directly to a 30-year-old ledger will trigger a catastrophic system failure. Replacing the core is a multi-year, multi-million dollar risk that most boards cannot stomach.
The solution is not replacement, but orchestration. By implementing a high-speed translation layer, banks can decouple their modern digital experience from their aging infrastructure. This analysis details how Adanto Software’s engineering of this middleware bridge has effectively leveled the playing field between regional banks and global titans.

The Legacy Anchor: Why Traditional Cores Fail the Digital Test
Most regional and community banks rely on cores that were never intended for the public internet. These systems are optimized for stability and record-keeping, often using batch processing to update balances overnight. When a bank decides to launch a youth platform where kids expect an instant “level up” after a chore is completed, the core becomes a bottleneck.
A direct integration into a legacy core is often a recipe for system instability. It is too rigid, too slow, and too expensive to modify. To innovate, banks must find a way to let their legacy system do what it does best (be the system of record) while allowing a modern front-end to do what it does best (engage the user).
The Orchestration Layer
Youth banking requires specialized features: parental controls, chore-based rewards, and educational modules. Platforms like REGO provide these features out of the box, but they require deep integration into the bank’s ledger to move money.
The orchestration layer is what makes a REGO integration viable for a community bank. Rather than trying to program parental “spend limits” into a 1990s core, Adanto builds those rules into the orchestration layer. The middleware validates the transaction against the REGO-defined rules and only sends the final, pre-approved transaction to the core for posting. This reduces the logic burden on the legacy system and accelerates time-to-market.
Implementing Scalable Middleware
For a CIO looking to move away from “spaghetti code” integrations, the path forward requires a structured architectural shift.
Phase 1: The API Audit
Before building, identify every touchpoint where the digital platform needs to communicate with the core. Map out the data flow: what needs to be real-time (authorizations) and what can be near-real-time (monthly statements).
Phase 2: Deploying the Message Bus
Introduce a message broker. This acts as the “traffic controller” for your data. It allows you to throttle requests to the core during peak hours, ensuring the legacy system stays within its operational limits.
Phase 3: Data Virtualization
Create a “Read-Only” replica of your core data in a modern database. Direct all balance inquiries and transaction history views to this replica. This reduces the load on the core by as much as 60%, as the vast majority of banking app interactions are “read” actions rather than “write” actions.
Phase 4: Pilot and Parallel Run
Launch the youth platform to a small subset of users. Monitor the “heartbeat” of the legacy core. The orchestration layer should provide deep observability, showing you exactly how much latency is introduced at each hop.
Conclusion
Community banks do not need to replace their core systems to compete with digital-first neobanks. The orchestration layer is the pragmatic middle ground. It allows for the rapid deployment of sophisticated tools like REGO while protecting the stability of the institution’s foundational ledger. By adopting an Event-Driven Architecture, banks can transform their legacy infrastructure into a high-performance engine capable of meeting modern consumer expectations.
