Cloud & DevOps – From Engineer to Cloud Architect | Consolidated TDD – Structure and Use Cases | R8

In this video, we explore how to understand and prepare a Consolidated Technical Design Document (TDD) for an AWS-to-GCP migration project. We explain the purpose, structure, and key sections of a Consolidated TDD, including current-state and target-state architecture, application dependencies, infrastructure, networking, security, and CI/CD. We also cover migration strategy, validation, cutover, rollback, and acceptance criteria. Finally, we discuss how an Associate Architect uses a Consolidated TDD to document technical designs, coordinate multiple application migrations, and support architecture reviews using a practical sample document. • Topics covered: • Consolidated TDD overview, purpose, and structure • Document control, executive summary, scope, and assumptions • AWS current-state and GCP target-state architecture • Application workloads, infrastructure, and technical dependencies • GKE, Terraform, networking, IAM, and security design • CI/CD pipelines, configuration, and managed services • Migration strategy, validation, cutover, and rollback planning • Consolidated TDD use cases, architecture reviews, and Associate Architect responsibilities
