iDev successfully migrates a major commercial bank's core systems to hybrid cloud, achieving 99.99% availability.
项目背景该银行拥有超过2000万客户，原有核心系统运行在老旧的物理服务器上，面临扩展性差、维护成本高、容灾能力不足等痛点。iDev受邀为其提供全方位的云迁移服务。迁移方案iDev采用"渐进式迁移"策略，分三个阶段完成迁移：首先迁移非核心业务系统（邮件、OA等），然后迁移数据分析和风控系统，最后完成核心交易系统的迁移。全过程实现零停机。成效迁移完成后，系统可用性从99.9%提升至99.99%，交易处理能力提升5倍，年度IT基础设施成本降低35%。
Project BackgroundThe bank serves over 20 million customers, with its core systems running on legacy physical servers facing challenges of poor scalability, high maintenance costs, and insufficient disaster recovery capabilities. iDev was engaged to provide comprehensive cloud migration services.Migration ApproachiDev adopted a "progressive migration" strategy completed in three phases: first migrating non-core systems (email, OA), then data analytics and risk control systems, and finally the core transaction system. The entire process achieved zero downtime.ResultsPost-migration, system availability improved from 99.9% to 99.99%, transaction processing capacity increased 5x, and annual IT infrastructure costs decreased by 35%.
