Similarly, Deloitte’s Cloud practice in London provides comprehensive advisory and implementation services, with a strong emphasis on risk management and governance for financial institutions. Deloitte’s approach often integrates cloud migration with broader digital transformation, ensuring that legacy systems are modernised without compromising data sovereignty or audit trail integrity, which is critical for firms adhering to Basel III and Solvency II requirements. Capgemini, with its significant presence in the City, specialises in cloud migration for financial services through its Cloud Infrastructure Services unit, offering solutions like the Cloud Platform for Financial Services which preconfigures environments to meet PCI DSS and SOX standards. Their expertise spans from hyper-scaler migrations to hybrid cloud models, particularly for capital markets and retail banking clients facing operational resilience mandates. Infosys, through its London innovation hub, delivers the Infosys Cobalt cloud portfolio, which includes industry-specific accelerators for financial services, such as automated compliance checks and real-time fraud detection frameworks embedded during the migration process. This firm excels in migrating core banking systems to cloud-native architectures, reducing total cost of ownership while maintaining transaction throughput for high-frequency trading environments. Wipro’s FullStride Cloud Services in London focuses on financial sector cloud adoption, utilising its convergence maturity framework to address security concerns like tokenisation and encryption key management. Wipro has developed a Financial Services Cloud Migration Toolkit that streamlines the transition of mission-critical applications, including payment processing and risk analytics, with built-in redundancies for uptime SLAs. Cognizant’s Cloud360 practice in London partners with financial institutions to create custom migration roadmaps, particularly for those undergoing open banking transformations. Their financial services cloud solutions incorporate regulatory technology (RegTech) to automate reporting and ensure real-time compliance with the Bank of England’s stress testing guidelines. IBM, a long-standing player in London’s financial district, offers its IBM Cloud for Financial Services, which is the first cloud platform designed specifically for the industry, integrating risk management controls and encryption guarantees as standard. IBM’s consulting arm provides deep advisory on mainframe to cloud migrations, a common challenge for large London-based banks, while ensuring alignment with the European Banking Authority’s outsourcing guidelines.
