Zorluk: ZorCreating Conceptual, Logical, and Physical Architectures

An international logistics enterprise is establishing design standards to translate its logical architecture into a physical GCP architecture. The logical design specifies three core requirements: a stateless HTTP API ingestion tier with minimal operational complexity, a relational database tier requiring multi-region synchronous write consistency, and a network security boundary that prevents authorized users from exfiltrating data to external public storage. Which physical architecture mapping correctly aligns GCP services to these logical requirements?

  1. Deploy the stateless API tier on Cloud Run, use Cloud Spanner for the relational persistence layer across multiple regions, and enclose the cloud resources within a VPC Service Controls security perimeter.Cevap
  2. B
    Deploy the stateless API tier on a multi-zonal Google Kubernetes Engine (GKE) cluster, use Cloud Spanner for the multi-region relational database, and enclose the cloud resources within a VPC Service Controls security perimeter.
  3. C
    Deploy the stateless API tier on Cloud Run, use Cloud Spanner for the multi-region relational database, and rely exclusively on fine-grained IAM custom roles to prevent internal users from copying sensitive data externally.
  4. D
    Deploy the stateless API tier on Cloud Run, provision Cloud SQL for PostgreSQL with cross-region read replicas for the database layer, and enclose the cloud resources within a VPC Service Controls security perimeter.

Cevap

The physical architecture mapping that uses Cloud Run for the stateless API tier, Cloud Spanner for multi-region relational persistence, and VPC Service Controls for perimeter isolation correctly fulfills the logical requirements.
The solution using Cloud Run, Cloud Spanner, and VPC Service Controls accurately translates all logical requirements into physical GCP architecture. Cloud Run provides serverless compute with zero cluster management; Cloud Spanner supports multi-region synchronous relational transactions; and VPC Service Controls establishes network perimeters to prevent data exfiltration beyond IAM controls.

Adım Adım Çözüm

1
Analyze the logical requirements for the compute tier
Stateless HTTP API ingestion requiring minimal operational management maps physically to Cloud Run rather than GKE.
Cloud Run is a fully managed serverless platform that automatically scales to zero and removes container infrastructure management.
2
Analyze the logical requirements for the persistence tier
A relational database requiring multi-region synchronous write consistency maps physically to Cloud Spanner.
Cloud SQL only supports single-region primary instances with asynchronous cross-region replicas, whereas Cloud Spanner provides globally distributed synchronous ACID transactions across regions.
3
Analyze the logical requirements for data security and exfiltration prevention
Preventing data exfiltration by authorized entities requires physical perimeter isolation using VPC Service Controls.
IAM permissions control access identity but cannot restrict data movement across network boundaries to non-sanctioned GCP resources.
