Infrastructure pressures and opportunity
Modern fintech firms and financial institutions face escalating demands on infrastructure. Whether it’s ultra-low latency trading, real-time payments, AI-driven risk analytics or large volume transaction processing, the stakes are high. According to a 2025 survey by Digital Realty, 79% of financial services companies tie their data-location strategy directly to their AI roadmap.
At the same time, many in-house data-centres struggle to keep pace: ageing power/cooling systems, inflexible layouts, limited connectivity, and regulatory burdens all add cost and complexity. Colocation hosting offers a viable alternative: leasing space, power, cooling and connectivity in specialist facilities rather than owning and operating everything.
Market momentum: what the numbers tell us
The colocation sector is growing rapidly: driven by digital transformation across industries, including finance. Key statistics:
- The global data-centre colocation market was estimated at USD 69.41 billion in 2024, and is projected to reach USD 165.45 billion by 2030, representing a compound annual growth rate (CAGR) of ~16%.
- Some forecasts push higher: one source projects the market will hit USD 204.4 billion by 2030, growing at ~14.4% from 2025.
- Another estimate suggests the market will reach USD 211.73 billion by 2032, growing at ~12.5% CAGR from 2025.
- According to the 2025 Global Data Centre Trends report (CBRE), average rental rates in key markets jumped ~14.7 % year-over-year, underpinned by demand from enterprise users including financial services.
These numbers illustrate that colocation is not a niche or stop-gap solution — it’s becoming a mainstream infrastructure model.

What colocation delivers for fintech & financial institutions
Here are the tangible benefits and how they apply specifically to finance:
Performance, latency and connectivity
Financial firms, particularly those in trading, payments and real-time services, depend on minimal latency and high throughput. Colocation facilities are typically located near major connectivity hubs, exchange points and carrier networks: enabling faster access and improved performance compared with many legacy internal data-centres or public-cloud models. For example, Digital Realty emphasises that “If you don’t have the right data where you need it, then your AI strategy is broken before it starts.”
Regulatory alignment and security posture
Finance is heavily regulated: from payments to banking to capital markets, organisations must meet standards such as PCI-DSS, ISO 27001, SOC 2, and regional banking/finance regulations. Colocation providers build and operate infrastructure with strong physical security (cages, access controls, video surveillance), audit logs and compliance frameworks helping clients reduce risk and accelerate time-to-market.
Scalability, cost-efficiency and modernisation
Rather than building or expanding their own data-centres (with high fixed costs, long lead-times and operational burdens), financial firms can lease rack-space or cages, adjust power usage, and scale more flexibly. Many legacy internal facilities are inefficient: colocation offers modern hardware, improved power-usage efficiency and updated cooling/power setups.
Resilience, business continuity and risk reduction
Downtime or degraded performance in financial services equals lost value: transactions missed, customers dissatisfied, regulatory scrutiny. Colocation facilities offer high-availability configurations, redundant power/cooling/network, multi-carrier connectivity, and geographically dispersed sites. These features support continuity and disaster-recovery strategies without having to invest in a second wholly-owned data-centre.
Use-cases where colocation drives value
Here are specific finance-sector scenarios where colocation offers measurable advantage:
Algorithmic trading / market-making
Firms located in or near exchange buildings or interconnection hubs (via colocation) gain microsecond advantage.
Payments processors & card networks
High-volume, high-availability systems with strict compliance needs benefit from colocation’s secure, scalable infrastructure.
Fintech scale-ups and challenger banks
These firms need scalable, compliant infrastructure without heavy upfront investment — colocation meets that need.
Legacy banks modernising infrastructure
Many institutions are moving away from ageing in-house data-centres; colocation offers a step-change in flexibility, cost and performance while preserving control.
Key evaluation criteria for financial firms
When choosing a colocation partner or strategy, financial institutions should assess:
- Certifications and audit capability: Provider meets regulated-industry standards (PCI-DSS, ISO 27001, SOC 2), supports audit rights, and maintains clear logs.
- Connectivity architecture and latency footprint: Carrier options, dark-fibre availability, proximity to market/exchange infrastructure, peering ecosystem.
- Governance, contract clarity & exit strategy: Ensure hardware/service maintenance responsibilities are defined, data-ownership/exit terms are clear, and audit/regulatory rights are preserved.
- Cost transparency and total cost of ownership (TCO): Understand power usage effect (PUE/WUE), ancillary costs (remote hands, connectivity), compare with internal ownership model.
- Hybrid/edge support: If firm uses a mix of colocation + public/private cloud + edge nodes, ensure provider supports hybrid models and integration.
- Scalability and service-model flexibility: Ability to increase rack space, power density, support high-density workloads (AI/ML), scale up/down as needed.
- Operational resilience and support: 24/7 remote-hands, monitoring, SLAs, multi-site/disaster-recovery capabilities.
Strategic caveats and risk considerations
Conclusion
When financial institutions and fintech firms shift the lens from “infrastructure as cost centre” to “infrastructure as competitive enabler”, colocation hosting emerges as a powerful model. It offers the performance, compliance, scalability and resilience that modern finance demands and can tilt cost and risk structures in favour of agility and innovation.
The market momentum is clear: growing size, strong demand, rising rental rates and a broadening set of use-cases across finance and other sectors. With infrastructure evolving fast, driven by AI/ML, embedded finance, open banking, real-time processing: firms that adopt the right colocation strategy will be better positioned to innovate and scale.
With careful selection and governance, colocation is not merely an outsourcing choice: it’s a strategic infrastructure lever.
