Legacy data center designs create critical bottlenecks as financial institutions race to deliver instant payments, AI-driven services, and always-on digital experiences. Three infrastructure realities are reshaping how financial services institutions (FSIs) approach modernization:
4-10x
increase in rack power density as FSIs adopt AI and high-performance computing workloads, with loads rising from 5 to 20-30 kilowatts (kW), and AI model training reaching 50 kW per rack.¹
99.99%
availability requirement for core transaction platforms means only 52 minutes of acceptable downtime per year.²
55%
of banks cite legacy systems as the top barrier to digital transformation, with aging infrastructure constraining their ability to support real-time payments, AI workloads, and regional expansion.³

What you'll learn
Legacy constraints limiting modernization
Why power distribution, cooling architectures, and space limitations inherited from batch-processing designs can't support AI, real-time payments, and high-density workloads.
Specific risks of aging infrastructure
How legacy power and cooling systems elevate operational risk, from limited edge monitoring to thermal systems that fail under 50 kW AI workloads.
Technical requirements for real-time FSI workloads
The power densities (20-50 kW per rack), cooling architectures, and availability service-level agreements (SLAs) needed for payments processing, fraud detection, and digital trading.
Phased modernization without disruption
Assessment frameworks and hybrid strategies for upgrading infrastructure while maintaining 99.99% uptime for mission-critical systems.
Business drivers creating infrastructure stress
How real-time payments, embedded finance, generative AI (GenAI) personalization, and cross-border expansion are pushing legacy systems beyond capacity.
