The following is a comprehensive documentation template I have developed to streamline the process of documenting cloud architecture and engineering projects that I make public. This template follows the natural lifecycle of architectural and engineering practices, organized in a chronological pipeline for clarity and completeness.
The documentation starts by emphasizing business value, illustrating how the solution or architecture supports and optimizes business operations. Technology, in this context, serves as a means to align with business objectives—ensuring scalability, reliability, security, operational efficiency, and ease of monitoring and management—while remaining adaptable to inevitable changes.
I have aimed to cover 95% of real-world scenarios, taking into account scalability, security, compliance, cost management, and operational nuances. However, I acknowledge that each project is unique, and personalized detailing may be required based on specific use cases.
This template is one example of my approach to documenting projects. For a more TOGAF-focused documentation template, please refer to the "TOGAF Master Documenting Template" repository

- Utilize cost forecasting and optimization strategies, including Spot Instances, Reserved Instances, and right-sizing.
- Implement tagging policies for cost allocation, automate resource management, and ensure continuous cost analysis.
- Establish data retention, archiving, and compliance policies, and ensure privacy with encryption and anonymization.
- Define and document recovery time objectives (RTO) and recovery point objectives (RPO) for business continuity.
- Continuously refine your business continuity plan based on testing results and incident lessons learned.
- Document user journeys, performance metrics, accessibility, and conduct usability testing to improve the end-user experience.
- Plan for organizational change management, including training, communication strategies, and fostering a DevOps culture.
- Conduct a comprehensive project review, identify lessons learned, and integrate continuous feedback for improvement.
- Explore the use of AI/ML, edge computing, and blockchain, where applicable, to enhance innovation.
- Optimize energy consumption, track the environmental impact of cloud resources, and adopt greener IT practices.
- Provide a deep dive into design decisions, optimizations, and innovative solutions employed in the project.
- This section provides a professional summary outlining any additional considerations or potential modifications that may arise during the project lifecycle. It includes architectural changes, alternative solutions, and enhancements based on evolving business needs, emerging technologies, or operational improvements.
- It emphasizes adaptability and future-proofing to accommodate dynamic requirements and scalability demands.
- Key areas to consider:
- Future scalability or performance adjustments
- Emerging technologies that could be integrated later
- Potential trade-offs between cost, performance, and security
- Provide definitions for all technical terms, acronyms, and jargon used throughout the documentation to ensure clarity for all readers.
- The glossary serves as a quick reference point for both technical and non-technical stakeholders.
- List external references, such as industry standards, whitepapers, frameworks, and any third-party tools utilized during the project.
- Include links to relevant documentation and best practices (e.g., NIST, ISO, CIS Benchmarks) to ensure adherence to established guidelines.
- This section offers a high-level summary of the entire project, detailing its objectives, scope, key decisions, and results. It focuses on aligning the solution with business goals and highlights major milestones achieved during the project lifecycle.
- The summary also provides insights into project performance, operational efficiencies, and key outcomes, ensuring that the solution has delivered value to the organization.
- Include metrics for success and feedback from stakeholders where applicable.
- Provide a detailed table of contents for all the artifacts and documentation generated throughout the project, organized by categories such as architecture diagrams, deployment scripts, security assessments, compliance reports, and testing results.
- This section ensures easy navigation for stakeholders and provides a clear overview of the resources produced during the project.
- Present a detailed, itemized table breaking down the cost analysis of the project, including potential costs per technology or service used (e.g., AWS, Azure, GCP services, infrastructure costs, third-party services).
- Table Example:
| Technology/Service | Estimated Cost Range (USD) | Notes |
|---|---|---|
| AWS EC2 Instances | $500 - $1000 / month | Based on reserved instance pricing for t3.large |
| S3 Storage | $50 - $200 / month | Estimated based on data storage and access patterns |
| RDS (PostgreSQL) | $300 - $800 / month | Cost varies based on instance size and storage needs |
