Financial institutions face mounting pressure to modernize, even as they maintain regulatory compliance across multiple jurisdictions. Meanwhile, cloud adoption continues to accelerate. But while “adoption of public cloud services has increased rapidly over the last decade… models of adoption continue to vary across the financial sector,” the U.S. Department of the Treasury describes. Firms need strategic guidance to navigate the complexities of distributed infrastructure as they consider cloud approaches—hybrid and multi-cloud in particular.
Understanding Your Infrastructure Options
There are fundamental differences between hybrid and multi-cloud in terms of both architecture and implementation.
Multi-Cloud Strategies
Multi-cloud approaches involve using multiple cloud providers to achieve redundancy and avoid vendor concentration. FIs can configure cloud services for a higher level of resilience to operational incidents through various approaches. These may include “using separate CSPs for different applications,” as Treasury describes.
Benefits include:
- Vendor diversity advantages, reducing single points of failure
- Risk distribution across multiple providers
- Enhanced negotiating position with cloud service providers
Hybrid Cloud Architecture
Hybrid cloud computing comprises “one or more public and private clouds that operate as separate entities but are integrated at the data, process, management, or security layers,” as Gartner describes. This approach requires existing private cloud capabilities and offers specific advantages for financial institutions managing sensitive data and regulatory requirements.
Key characteristics include:
- Integration of private and public environments at multiple layers
- Unified management capabilities across infrastructure types
- Workload flexibility based on sensitivity and regulatory requirements
Hybrid cloud may be better positioned to address financial firms’ regulatory pressures, “allowing sensitive data to be stored locally while using the power of public cloud computing for [non-sensitive] applications and non-sensitive information,” International Continental Exchange (ICE) describes. Current research shows the hybrid cloud market is projected to reach $158 billion in 2025, with growth to $430 billion by 2030.
Critical Cross-Border Compliance Considerations
Financial institutions operating across jurisdictions face complex regulations that must shape their cloud deployment strategies. For example, Treasury notes that “international regulatory concern over cloud services also has the potential to prevent globally active U.S. financial institutions from deploying cloud services across their overall enterprise.” Here we consider some solutions for overcoming challenges with international regulations.
Data Sovereignty Requirements
Data residency laws vary significantly by region and present ongoing challenges for global financial institutions. Key considerations include:
- Regional variations: Understanding specific data localization requirements in each jurisdiction
- GDPR implications: Ensuring compliance with European data protection regulations
- Cross-jurisdictional data flows: Managing data movement with regulatory compliance
- Digital Operational Resilience Act (DORA): Meeting mandatory resilience expectations
Regulatory Compliance Automation
Financial institutions can implement automated compliance monitoring to manage regulatory requirements across multiple jurisdictions. Effective approaches include:
- Real-time regulatory change tracking systems
- Automated audit trail generation and documentation
- Integration with existing compliance frameworks
Cross-Border Data Transfer Protocols
Secure data movement procedures can be highly effective when operating across multiple jurisdictions as well. Essential elements include:
- Encryption and access controls aligned with highest regional standards
- Shared responsibility model implementation with clear delineation of duties
- Regular assessment of cross-border data transfer compliance
Integration with Trading and Portfolio Management Systems
Despite their advantages, hybrid cloud environments pose unique challenges when maintaining performance and reliability for mission-critical financial applications. “More financial institutions move their quantitative research, risk management, and back-office applications to a cloud environment,” while core trading systems require special consideration, ICE describes. Here we consider some of those challenges and approaches that can help FIs overcome them.
Legacy System Integration Challenges
Financial institutions must carefully manage the integration of existing trading infrastructure with cloud-based services. In one case study about Discover Financial Services, “more workloads were moved [to the cloud] in the first six months… than in all the years before, by far, orders of magnitude more” using containerized approaches, CIO Magazine reports.
Key strategies include:
- Assessment of existing infrastructure: Comprehensive evaluation of current trading systems
- Containerization strategies: Using technologies like Red Hat OpenShift to enable portability
- Phased migration approaches: Gradual transition of non-critical workloads before core systems
Performance and Latency Requirements
ICE emphasizes the importance of maintaining “real-time market data [within] public, private and hybrid cloud environments” while respecting local regulations and data security laws. Critical requirements include:
- Low-latency connectivity for high-frequency trading applications
- Real-time data synchronization across distributed environments
- Network optimization to minimize performance degradation
Business Continuity and Disaster Recovery
The distributed nature of cloud infrastructure offers enhanced resiliency opportunities. According to Program on International Financial Systems (PIFS) research, “the scalability of cloud services allows FIs to handle unexpected capacity requirements, whether due to an unanticipated surge in trading activity or a malicious cyberattack.”
Essential components include:
- Multi-region deployment strategies leveraging cloud provider infrastructure
- Comprehensive failover and backup procedures
- Regular stress testing and validation of recovery capabilities
Security and Risk Management Framework
Building comprehensive security across a distributed infrastructure requires addressing both concentration and operational threats. Treasury analysis notes that “concentration could expose many financial services clients to the same set of physical or cyber risks.” Here we consider some solutions for overcoming challenges with security and risk management.
Zero Trust Security Architecture
Financial institutions must implement robust security frameworks that account for distributed infrastructure. Zero Trust security architecture replaces traditional, perimeter-based security approaches with leading-edge capabilities that can help. Key principles include:
- Identity and access management: Comprehensive authentication across all environments
- Network segmentation: Logical isolation of sensitive systems and data
- Continuous monitoring: Real-time threat detection and response capabilities
Vendor Risk Management
Managing relationships with multiple cloud providers requires sophisticated risk assessment frameworks. FIs can “periodically assess and take reasonable steps to manage concentration and lock-in risks” posed by a single-provider, non-diversified supply chain, and concentrated geographical dependencies, PIFS reports.
Critical elements include:
- Third-party assessment frameworks for cloud service providers
- Concentration risk evaluation across the entire vendor ecosystem
- Exit strategies and vendor diversification planning
Operational Resilience
Treasury emphasizes that FIs are “ultimately responsible for their own operational resilience,” regardless of cloud deployment models, “and for taking steps to…manage risks from the services they select.”
Essential components include:
- Comprehensive incident response procedures
- Regular business impact assessments
- Clear recovery time objectives for critical systems
Operational Excellence and Cost Optimization
Achieving efficiency and financial benefits requires strategic resource allocation and automation. Fortunately, hybrid cloud enables an “extremely flexible environment that ranges all the way from traditional [business intelligence] reporting to new, cutting-edge AI and machine learning applications,” according to an interview in Forbes. Here we consider strategies for FIs to achieve operational excellence while optimizing costs.
FinOps Best Practices
Effective financial management of hybrid cloud environments requires specialized approaches. Gartner research emphasizes the importance of “cost and consumption tracking” as a key requirement for cloud deployments.
Key practices include:
- Automated cost tracking: Real-time visibility into resource consumption across providers
- Resource optimization: Using analytics to identify and eliminate waste
- Performance-based negotiations: Leveraging usage data in vendor discussions
Automation and AI Integration
According to Forbes, “88% of IT leaders have added artificial intelligence to their workflows, with 60% using AI to improve the customer experience.: Integration opportunities include:
- Intelligent workload placement based on cost and performance metrics
- Predictive scaling and optimization algorithms
- Automated compliance and governance processes
Performance Monitoring and Optimization
Comprehensive visibility across hybrid environments enables continuous improvement. Essential capabilities include:
- Real-time monitoring across public and private cloud environments
- Capacity planning and forecasting based on historical usage patterns
- Continuous improvement processes incorporating stakeholder feedback
Emerging Technologies and Future Considerations
Cloud capabilities enable advanced analytics, AI, and regulatory technology applications that drive competitive advantage. According to the Institute of International Finance (IIF), “84% of FIs are already applying AI/ML techniques in production, and an additional 11% are either applying those techniques in pilot projects.” Here, we consider how emerging technologies should shape future considerations for hybrid cloud approaches.
AI and Machine Learning Integration
As indicated, financial institutions increasingly leverage cloud-native AI deployment strategies. Key considerations include:
- Data pipeline optimization: Ensuring high-quality data feeds for AI models
- Model governance: Implementing validation frameworks for AI applications
- Regulatory compliance: Managing AI model risk and explainability requirements
Regulatory Technology Applications
Automated compliance monitoring represents a significant opportunity for operational improvement. Bloomberg analysis shows even the Financial Conduct Authority (FCA) is “improving how it uses data through its advanced analytics unit, the synthetic data expert group, machine learning in fighting scams and trade surveillance,” and supporting AI surveillance development for FIs in the market.
Applications include:
- Automated transaction monitoring and reporting
- Real-time risk assessment and alerting
- Intelligent audit and regulatory reporting systems
