Core Insights - Huawei's 2025 Cloud Adoption Framework (CAF) report outlines a comprehensive end-to-end lifecycle framework for cloud transformation, providing methodologies and best practices across six stages: strategy formulation, top-level planning, research and assessment, solution design, implementation, and operational governance [1][2][23]. Group 1: Strategy Formulation - The strategy formulation phase focuses on stakeholder interest analysis, identifying business, technical, and financial drivers, and using a cloud maturity assessment model to diagnose the current state across ten dimensions [1][2]. - Goals for cloud transformation should adhere to the SMART principles and quantify expected benefits [1][2]. Group 2: Top-Level Planning - The top-level planning phase emphasizes establishing a Cloud Center of Excellence (CCoE) to lead the cloud transformation project and designing a secure, compliant multi-account operational environment known as the Landing Zone [1][2]. - It involves creating a security architecture and platform engineering, as well as determining suitable cloud operating models and application lifecycle management processes [1][2]. Group 3: Research and Assessment - The research and assessment phase follows the principle of "easy first, rough first, continuous iteration," forming cross-departmental teams to conduct infrastructure, application systems, and big data assessments [2][3]. - Various research methods are employed to gather resource information, relationships, and cloud migration needs, culminating in the selection of cloud services based on business scenarios [2][3]. Group 4: Solution Design - The solution design phase requires the completion of foundational environment, application deployment architecture, and big data architecture designs, along with the formulation of a 6R migration strategy and tagging scheme [2][3]. - A pilot project is conducted to validate feasibility before batch planning and cost budgeting [2][3]. Group 5: Implementation - The implementation phase progresses in batches, forming specialized teams to deploy infrastructure based on a four-layer application architecture design, offering various migration options [2][3]. - A Runbook is established to standardize operational processes [2][3]. Group 6: Operational Governance - The operational governance phase focuses on lean governance, deterministic operations, security operations, FinOps, and continuous optimization to ensure long-term stability and efficiency of cloud systems [2][3]. - The report highlights that cloud transformation is a systemic project requiring a balance between centralized control and business agility, utilizing automation tools and standardized processes to reduce complexity [2][3].
