Battle-Tested Expertise in Financial Technology
Traditional on-premise banking systems create significant obstacles for growth and innovation. These legacy platforms require massive capital investments in hardware, software licenses, and data center facilities. Maintenance costs consume 60-70% of IT budgets, leaving little for innovation.
Scalability challenges emerge when banks try to adapt to organizational changes. Any infrastructure modification or workload adjustment requires extensive time, leading to substantial downtime that impacts customer service. System upgrades take months or years to implement, during which competitors launch new features weekly.
Key Pain Points of On-Premise Systems:
High upfront capital expenditure for hardware and infrastructure. Lengthy procurement cycles delay project starts by 3-6 months. Limited scalability forces over-provisioning for peak demand. Disaster recovery requires duplicate infrastructure investments. Software updates risk system downtime and service interruptions. Talent shortages make finding skilled mainframe engineers difficult.
