Zorluk: OrtaCreating Conceptual, Logical, and Physical Architectures

An enterprise investment bank is modernizing its portfolio risk analytics platform on Google Cloud. You are serving as the Lead Cloud Architect responsible for translating business requirements into a complete cloud solution architecture. In which chronological order should you execute the architectural design stages, from high-level domain mapping down to concrete GCP resource specification?

  1. 1Establish the Conceptual Architecture by identifying high-level business capabilities and domain boundaries without prescribing technology stacks.
  2. 2Develop the Logical Architecture by defining functional service tiers, data flow patterns, and interface boundaries between components.
  3. 3Map the Logical Architecture to the Physical Architecture by selecting concrete Google Cloud services to fulfill each functional tier.
  4. 4Detail the Physical Architecture implementation by specifying exact infrastructure parameters, subnet CIDRs, IAM roles, and encryption settings.

Cevap

The correct order follows the standard architecture design lifecycle: (1) Establish the Conceptual Architecture to capture business capabilities, (2) Develop the Logical Architecture to define functional components and data flows, (3) Map the Logical Architecture to Physical Architecture by selecting specific Google Cloud services, and (4) Detail the Physical Architecture implementation with concrete network, security, and resource parameters.
The standard architectural design process progresses systematically from business intent to concrete technical execution: Conceptual Architecture defines high-level business domain capabilities; Logical Architecture defines technology-neutral functional tiers and data flows; Physical Architecture service mapping selects specific GCP products; and Physical Architecture detailing establishes exact operational and security parameters for deployment.

Adım Adım Çözüm

1
Identify the conceptual design phase.
Establish high-level business capabilities without technology lock-in.
Architecture starts with understanding business goals and domain boundaries at the conceptual level.
2
Identify the logical design phase.
Define technology-agnostic service tiers and interaction patterns.
Logical architecture structures the solution into functional modules and data flows based on conceptual requirements.
3
Identify the physical service selection phase.
Map logical tiers to concrete GCP services.
Physical design translates logical requirements into specific GCP products that satisfy SLA, throughput, and operational needs.
4
Identify the physical parameterization phase.
Configure concrete infrastructure parameters like subnet CIDRs, IAM bindings, and CMEK settings.
Final deployment readiness requires explicit configuration of network topologies, access rules, and security keys.

Sequential architectural translation from conceptual model (business focus) to logical model (functional tiers) to physical model (GCP product selection and explicit parameterization).
