Zorluk: KolayCreating Conceptual, Logical, and Physical Architectures

When designing a new cloud solution on Google Cloud, an architect documents the system across different abstraction levels. Arrange the architectural views in order from the highest level of abstraction (business-focused) to the lowest level of abstraction (concrete infrastructure implementation).

  1. 1Conceptual Architecture: High-level business requirements, operational constraints, and domain capabilities without specifying technology.
  2. 2Logical Architecture: Technology-agnostic component diagrams, data flows, interaction tiers, and functional interface definitions.
  3. 3Physical Architecture: Concrete GCP service selections, VPC network subnet topologies, IAM configurations, and resource provisioning blueprints.

Cevap

The correct sequence from highest to lowest abstraction is Conceptual Architecture, followed by Logical Architecture, and finally Physical Architecture.
The design process moves progressively from high abstraction to concrete execution: first establishing business requirements (Conceptual), then structuring functional components and data flows (Logical), and finally specifying exact Google Cloud services and network topologies (Physical).

Adım Adım Çözüm

1
Identify the conceptual phase.
Conceptual architecture focuses strictly on business capabilities and high-level requirements without technological commitments.
Designing starts by understanding business domain boundaries and strategic objectives at the highest level of abstraction.
2
Identify the logical phase.
Logical architecture breaks down conceptual needs into functional tiers, data flows, and interactions.
Before selecting specific vendors or products, functional components and communication patterns must be defined.
3
Identify the physical phase.
Physical architecture maps logical components directly into concrete Google Cloud services and infrastructure configurations.
Physical design is the final, lowest-abstraction implementation stage where specific technical resources (e.g., GKE, Cloud Spanner, VPCs) are selected and configured.
