For decades, mainframes have powered vital industries such as finance and government, offering unparalleled reliability and strength in managing complex tasks. Their consistent performance ensures that crucial operations stay seamless and efficient. Cloud computing and AI, however, have revealed the shortcomings of traditional mainframes. Outdated and inflexible, these systems impact resource scalability, delay application updates, stifle innovation, and limit adaptability—holding back enterprises from fully embracing digital transformation.
Mainframe modernization is the key for users, cloud providers, and mainframe companies to tackle these issues. Drawing from proven mainframe modernization strategies across various sectors, Huawei outlines essential technologies and practical approaches, and compiled these insights into the Mainframe Modernization: Mainframe-to-Cloud Migration White Paper. This white paper introduces a clear roadmap for migrating businesses from mainframes to the cloud in three steps. First, set up the cloud infrastructure. Next, migrate applications and data from mainframes to the cloud platform. Finally, refine development and maintenance workflows to ensure smooth operations.
This white paper explores how combining software and hardware can build a powerful cloud infrastructure that delivers exceptional reliability, performance, and security. It presents adaptable, open solutions like IaaS, DaaS, and PaaS designed for today's applications. The document reviews the standard technology roadmap for modernizing mainframes and details actionable steps for app migration. These steps involve assessing applications, redesigning systems, moving data, testing migrations, running parallel systems, and finalizing the switch. The paper also guides organizations in embracing agile development centered on applications and intelligently overhauling operations and maintenance after shifting mainframe workloads to the cloud.
This white paper supports mainframe users at various stages of modernization. It guides them in adopting open, agile, and intelligent technologies while preserving their systems' strengths. By doing so, it helps enterprises speed up their journey toward becoming more digital and intelligent.
