This document discusses how cloud computing can be applied in the finance industry. It notes that traditional finance IT systems have high hardware and software coupling, while cloud computing allows for more resource virtualization and decoupling. The document recommends a hybrid cloud approach for finance that uses both private and public clouds to provide flexibility, security, and business continuity. It identifies key areas where cloud computing can help finance firms, such as production systems, big data analytics, and disaster recovery. The hybrid cloud is presented as the best architecture to address the unique challenges of finance IT systems while preparing for future cloud adoption.
