Overall Framework
Huawei Cloud CAF provides comprehensive and systematic cloud transformation methodologies and best practices, covering the entire cloud transformation journey and the perspectives of all stakeholders involved in cloud transformation. The following figure shows the overall framework of CAF.

The cloud transformation journey consists of the following six phases in chronological order.
- Strategy formulation: Formulate a cloud transformation strategy that aligns with the organization's business and technology strategies. In this phase, you need to analyze stakeholder interests, identify key drivers for cloud transformation, assess cloud maturity, set cloud transformation objectives, evaluate potential benefits, and develop a cloud transformation strategy that aligns with the organization's business strategy.
- Top-level planning: Cloud transformation is a systematic project. It is not simply migrating application systems to the cloud. It necessitates a top-level framework for organizational structures, processes, and technologies. At the organizational level, you need to set up a Cloud Center of Excellence (CCoE) to lead, coordinate, and promote the cloud transformation project. At the technical level, you need to design the landing zone, security architecture, and platform engineering based on the Well-Architected Framework (WAF). At the process level, you need to design an optimized cloud operating model tailored to the organization's IT operations framework. Additionally, you need to formulate an application lifecycle management process aligned with the cloud operating model to fully realize the business value of cloud computing.
- Survey and evaluation: Conduct a survey on the organization's IT infrastructure, application systems, and big data platforms, analyze static configurations and dynamic runtime data, and evaluate the current statuses to select appropriate cloud services and provide actionable insights for the subsequent solution design.
- Solution design: In the top-level design framework of cloud transformation, design the cloud technical architecture, cloud application architecture, and cloud data architecture in detail based on the survey and evaluation results, the business architecture of the organization, and the WAF framework. Ensure the security, reliability, and high performance of cloud infrastructure and application systems through WAF design. In this phase, you need to formulate POC and batch migration plans for application systems based on their importance, select appropriate migration policies based on their characteristics, formulate a cloud cost budget plan, and finally output the low-level design.
- Adoption and implementation: Set up a landing zone based on the low-level design, deploy a scalable network infrastructure, and configure security and O&M baselines. Then, migrate application systems and big data platforms to or deploy them on the cloud, modernize applications on the cloud platform, or innovate applications and services on the cloud based on its innovative technologies.
- O&M governance: After application systems are migrated to or deployed on the cloud, the O&M governance phase begins. During this phase, lean governance, deterministic O&M, security operations, and cost operations are essential for cloud infrastructure, application systems, and big data platforms. Continuous optimization is performed following the WAF framework.
Cloud transformation projects involve many departments and stakeholders in the organization. These stakeholders participate in the decision-making of cloud transformation projects or influence each phase of the cloud transformation journey. As shown in Table 1, different stakeholders have different concerns and different business or technical perspectives.
Huawei Cloud CAF provides appropriate suggestions across all perspectives. These suggestions serve as a foundation for decision-making and actions, enabling your organization to develop target strategies tailored to your business characteristics and preferences.

The cloud transformation journey is a long, multi-faceted process involving a large number of personnel and tasks. To ensure success, enterprises should assign dedicated project managers to oversee the entire project. Employing scientific project management methods and actionable plans is crucial for enhancing the efficiency and quality of cloud transformation and ultimately driving the achievement of strategic transformation goals.
The directory structure of Huawei Cloud CAF aligns with the six phases of the cloud transformation journey. Each section outlines focus areas and practical suggestions from both business and technology perspectives, providing comprehensive guidance for cloud transformation.
