践行深度用云：主机上云，运维现代化核心能力

Investment Rating - The report does not explicitly state an investment rating for the industry Core Insights - The financial industry is undergoing a significant transformation with the migration of core systems to the cloud, driven by the need for digital transformation and the adoption of cloud-native technologies [7][8] - Major state-owned and joint-stock banks have completed pilot projects for migrating general business to core business on the cloud, entering the phase of large-scale migration [7] - The increasing reliance on cloud platforms for core business operations raises demands for higher availability and reliability, as any service interruption can lead to severe social impacts and credit crises [7][8] Summary by Sections 1. New Challenges Brought by Cloud Migration - Challenge 1: Designing high-availability cloud solutions and reliable operational support from an application perspective is critical, as traditional methods cannot meet the new availability standards [15][16] - Challenge 2: The rapid increase in the technology stack of cloud platforms complicates the implementation of end-to-end monitoring [17][18] - Challenge 3: The deep integration of cloud and network requires quick detection, localization, and recovery of issues [19][20] - Challenge 4: Addressing dual challenges of operational security and tenant security during cloud migration is essential [23][24] 2. Core Capabilities for Modernized Operations - The modernization of operations focuses on three main areas: platform operations, application operations, and security operations [31] - Platform operations must achieve full-link monitoring and deterministic fault recovery to ensure the stability of core applications on the cloud [33][34] - Application operations should prioritize reliability from the design phase, utilizing high-availability designs to enhance application reliability [37] - Security operations need to implement comprehensive security controls throughout the operational process to mitigate risks associated with operational errors and tenant security [38] 3. Detailed Operational Modernization Strategies - Full-link monitoring should be established to cover all layers from applications to cloud platforms, ensuring quick fault detection and diagnosis [39][40] - Deterministic fault recovery mechanisms should be developed based on a fault mode library to facilitate precise fault diagnosis and rapid recovery [64][65] - A proactive risk governance approach is necessary to anticipate and prevent operational risks, leveraging digital and automated solutions [36][68]
