Top Challenges Banks and Financial Institutions Face
Legacy banking infrastructure creates mounting technical debt, operational risk, and competitive disadvantage. Traditional banks must transform decades-old systems while maintaining stability, compliance, and customer trust, a challenge that requires specialized expertise in both legacy and modern technologies.
Decades-old mainframe systems block innovation
Your core banking runs on mainframes with COBOL code written 30+ years ago. Adding modern features like mobile banking, open APIs, or real-time payments requires complex workarounds. Every change risks stability. Technical debt compounds. Meanwhile, digital-first banks ship features weekly.
Heavy regulatory oversight slows innovation
Basel III, SOX, AML/KYC, and regional banking regulations require extensive documentation and compliance checks. Development teams spend more time on regulatory paperwork than building customer-facing features, causing delays in competitive product launches.
Integration pain across systems and APIs
Connecting legacy core banking systems with modern payment processors, third-party APIs, and cloud services is complex and risky. Poor integration architecture leads to data inconsistencies, transaction failures, and security vulnerabilities across the banking ecosystem.
COBOL and mainframe talent retiring rapidly
Developers who understand your mainframe architecture are retiring. COBOL experts are scarce and expensive. New graduates don't learn legacy technologies. You're losing institutional knowledge while struggling to find engineers who can maintain critical systems AND build modern cloud services.
Big-bang migrations too risky for operations
Replacing your core banking system in one go means massive risk, months of downtime, data migration failures, customer impact. But gradual transformation requires expertise in strangler patterns, event-driven architecture, and maintaining two systems simultaneously. Most banks lack this specialized knowledge.
Cannot compete with digital-first challengers
Neobanks launch features in weeks while your changes take quarters. Customers expect digital-first experiences. Your board demands transformation. But you're constrained by legacy systems, risk aversion, and the need to maintain operations. You need modernization velocity without legacy replacement risk.
Key Outcomes Scrums.com Delivers
Seamless Migration from Mainframe to Cloud
Transform COBOL-based core banking systems to cloud-native microservices without downtime. Our strangler fig pattern gradually replaces legacy functionality while maintaining operations. We've migrated systems processing millions of daily transactions with zero disruption. Reduce total migration time by 50% and cut legacy maintenance costs by 70% with our proven modernization frameworks.
Zero-Downtime Core Banking Transformation
Replace decades-old core banking systems while maintaining 24/7 operations. Our phased approach uses event-driven architecture, API gateways, and parallel processing to run old and new systems simultaneously—eliminating big-bang migration risk. Deploy incrementally, validate continuously, and maintain customer trust throughout transformation.
Mainframe Modernization Expertise
Access rare dual-expertise: engineers who understand mainframes (COBOL, AS/400, JCL) AND modern cloud platforms (AWS, Azure, microservices). Our teams bridge the knowledge gap between retiring experts and modern architecture—ensuring institutional knowledge transfers during transformation without creating single points of failure.
Legacy Integration Without Replacement
Not ready for full migration? We build modern services around legacy cores using API facades, event buses, and service meshes. Launch mobile banking, open APIs, and digital products while maintaining existing mainframe operations. Achieve modernization benefits without rip-and-replace risk.
