An enterprise financial institution is planning the migration of its core transaction settlement platform to Google Cloud. As the Principal Cloud Architect, you must lead the architecture design process by translating high-level enterprise business requirements into a fully deployed cloud infrastructure. In what order should you execute the architectural design and translation steps, moving from initial conceptual design down to physical implementation?
- 1Define high-level business capabilities, SLA/RPO/RTO requirements, and regulatory compliance boundaries to construct a vendor-neutral Conceptual Architecture.
- 2Decompose conceptual business capabilities into functional subsystem tiers, data interaction flows, and API boundaries to build the Logical Architecture.
- 3Map logical functional tiers to general cloud service paradigms (such as distributed transactional storage, asynchronous message streaming, and container orchestrators).
- 4Select concrete Google Cloud physical services and configurations (e.g., Cloud Spanner multi-region instance, Pub/Sub, GKE Enterprise, and VPC Service Controls) matching performance and security limits.
- 5Draft physical deployment specifications including VPC CIDR block allocations, IAM custom role policies, and Infrastructure as Code (IaC) scripts for environment provisioning.
Cevap
The correct order follows a top-down architectural progression: first, construct the vendor-neutral Conceptual Architecture based on business goals and compliance metrics; second, build the Logical Architecture by defining functional components and data flows; third, map logical tiers to abstract cloud service paradigms; fourth, select concrete Google Cloud products matching technical requirements; and fifth, draft physical deployment specifications, network configurations, and IaC scripts.
Enterprise cloud solution design moves systematically from business vision to executable infrastructure. The process begins with a vendor-neutral Conceptual Architecture to capture SLAs, business processes, and compliance requirements. Next, the Logical Architecture defines subsystem components, data interaction flows, and integration interfaces. Then, logical components are mapped to generic cloud architectural paradigms. After that, specific physical Google Cloud products (such as Cloud Spanner, Pub/Sub, GKE Enterprise, and VPC SC) are selected to meet throughput and availability constraints. Finally, detailed physical deployment specifications—including subnet CIDRs, IAM bindings, and IaC Terraform code—are produced to enable automated environment provisioning.
