A. Architecture Vision:
Strategic Goals and Objectives: - The architecture vision should clearly state the strategic goals and objectives of migrating to the cloud. This might include improving business agility, enhancing scalability, reducing operational costs, and fostering innovation through cloud native technologies.
Key Drivers: - Elaborate on the key drivers for migration, such as reducing capital expenditure (Capex), enabling rapid scalability, and leveraging cloud services for competitive advantage.
Scope and Desired Outcomes: - Define the scope of the migration project, including which applications and services will be moved to the cloud. Specify the desired outcomes, such as increased efficiency, improved performance, and enhanced disaster recovery capabilities.
B. Business Architecture:
Current State Analysis: - Provide a detailed analysis of current business processes and functions related to data management and IT operations. Identify pain points and inefficiencies in the existing setup.
Business Capabilities and Requirements: - Clearly outline the specific business capabilities and requirements that the cloud migration must support. This could include global data access, Realtime analytics, or improved customer experiences.
Alignment with Vision: - Ensure that the proposed business architecture aligns with the strategic vision outlined in section A.
C. Information Systems Architecture:
Assessment of Existing Systems: - Provide an in-depth assessment of existing information systems, databases, and data storage solutions. Identify dependencies and potential challenges.
Data Migration Strategy: - Explain how data will be migrated to the cloud, including data structures, formats, and tools to be used.
Security and Compliance: - Define data security and compliance requirements, including encryption, access controls, and regulatory compliance obligations.
D. Technology Architecture:
Current Technology Stack: - Evaluate the current technology stack and infrastructure, highlighting strengths and weaknesses.
Cloud Provider Selection: - Explain the process of selecting the cloud provider(s) based on market research. Justify the choice by considering factors like cost, performance, and service offerings.
Design of Cloud Environment: - Provide a high-level design of the technology architecture for the cloud environment, covering aspects like network topology, server configurations, storage solutions, and disaster recovery plans.
E. Opportunities and Solutions:
Alternative Solutions: - Present alternative solutions for the cloud migration, considering different cloud providers or hybrid cloud options.
Cost Benefit Analysis: - Conduct a comprehensive cost benefit analysis for each solution, factoring in initial migration costs, ongoing operational expenses, and potential ROI.
Provider Selection: - Explain why a particular cloud provider was chosen based on the evidence-based market research, cost analysis, and alignment with business goals.
F. Migration Planning:
Detailed Plan: - Develop a detailed migration plan with clear timelines, tasks, and resource allocation. Include dependencies between tasks.
Data and Service Sequence: - Identify the sequence in which services and data will be migrated, taking into account any interdependencies.
Risk Mitigation: - Address potential risks and provide mitigation strategies for each identified risk, including data loss, downtime, or security breaches.
G. Implementation Governance:
Governance Mechanisms: - Establish governance mechanisms to oversee the migration process, including roles and responsibilities, decision making processes, and escalation procedures.
Project Management Structure: - Create a project management structure to monitor progress, track milestones, and ensure adherence to timelines and budgets.
Security and Compliance Oversight: - Detail how security and regulatory requirements will be monitored and enforced throughout the migration.
H. Architecture Change Management:
Change Management Processes: - Implement robust change management processes to handle organizational changes resulting from the cloud migration. This should cover cultural shifts, new roles, and responsibilities.
Stakeholder Communication: - Describe how changes will be communicated to stakeholders, both internally and externally, and provide a plan for training and upskilling employees as needed.
Continuous Improvement: - Highlight the importance of continuous monitoring and management of the cloud architecture to adapt to evolving business needs and emerging technologies.
