Preliminary: In the preliminary phase, Google, in line with the CIO's requirements, conducts detailed market research to inform the client's cloud migration strategy. Stakeholders, including the CIO, IT procurement team, cloud architects, and data security experts, collaborate to define requirements. Google places emphasis on the Architecture Building Blocks (ABBs) such as market research data, cloud provider selection criteria, and a preliminary risk assessment. This ensures that the eventual cloud migration solution is based on a robust understanding of the market and potential risks. 

Phase A - Architecture Vision: Aligning with the CIO's vision to migrate services to the cloud, Google collaborates closely with key stakeholders such as the CIO, senior IT leadership, business unit leaders, and cloud architects to define a clear vision for the initiative. The ABBs include a cloud migration vision statement, stakeholder analysis, and a high-level migration roadmap. This phase ensures that the cloud migration aligns with the overarching business objectives and sets a strategic direction for the subsequent phases. 

Phase B - Business Architecture: Considering the user's preference for simplicity, Google analyzes current business processes engaging relevant stakeholders like business unit leaders, the procurement team, cloud architects, and data governance experts. The ABBs here include straightforward business process models, a procurement strategy, a data governance framework, and cloud service mapping. This ensures that the business requirements are clearly understood and integrated into the cloud migration strategy 

Phase C - Information Systems Architecture: In line with the user's request for simplicity with business keywords, Google involves stakeholders like IT architects, application owners, data engineers, and cloud architects. The ABBs include application architecture diagrams, infrastructure diagrams, data architecture models, and cloud service mapping. This simplifies the communication of the complex technical aspects of the migration while ensuring clarity in information systems architecture. 

Phase D - Technology Architecture: Google, understanding the CIO's requirement to migrate to the cloud, evaluates and selects cloud technologies in a straightforward manner. This involves stakeholders such as IT architects, cloud engineers, security experts, and the procurement team. ABBs include the cloud technology stack, infrastructure components, security architecture, and cloud service integration. This ensures that the chosen technology aligns with business needs and security considerations.

 Phase E - Opportunities and Solutions: Incorporating the need for an evidence-based decision on cloud providers, Google evaluates providers and develops a solution proposal. Stakeholders include the cloud migration team, the procurement team, business unit leaders, and IT leadership. ABBs include a cloud provider evaluation matrix, a cloud solution proposal, and a cloud migration roadmap. This phase ensures that the cloud provider is chosen based on market research and aligns with the overall solution proposal 

Phase F - Migration Planning: To meet the CIO's requirement for a migration plan, involving project managers, cloud engineers, the procurement team, and the cloud migration team. Google develops a detailed plan with ABBs including migration plans for each service, a timeline, milestones, resource allocation, and budget allocation. This ensures a well-organized and efficient migration process.

 Phase G - Implementation Governance: In response to the CIO's requirement to establish governance processes, Google involves stakeholders like project sponsors, project managers, cloud engineers, and the cloud migration team. Google defines roles and implements risk and change management. ABBs include a cloud migration governance framework, a project management plan, a risk management plan, and a change management plan. This establishes a structured approach to governance throughout the implementation phase.

 Phase H - Architecture Change Management: Considering the need for post-migration change management. Google involves stakeholders like cloud architects, cloud engineers, IT operations, and the cloud migration team. Google focuses on managing changes involving relevant stakeholders. ABBs include a change management process, change review and approval procedures, and a monitoring and improvement plan. This ensures a smooth transition and ongoing optimization post-migration.
