Zorluk: OrtaSelecting and Designing Storage and Database Resources

An enterprise logistics company is designing a new data architecture on Google Cloud for two distinct workloads running within a single GCP region:

1. A transactional order-processing engine requiring standard ANSI SQL support, single-region high availability with automatic zonal failover, and key governance managed via Cloud KMS.
2. A real-time audit logging component receiving thousands of append-only time-series events per second, requiring sub-10ms key-value write latencies and time-range scan capabilities.

Which TWO architectural storage and database service selections should the Cloud Architect make to fulfill these requirements with optimal cost and performance? (Select TWO)

  1. Provision Cloud SQL for PostgreSQL configured with High Availability (HA) across zones and Customer-Managed Encryption Keys (CMEK) for the transactional order-processing engine.Cevap
  2. B
    Provision Cloud Spanner as the transactional engine to achieve multi-zone consistency within the single region.
  3. Provision Cloud Bigtable as the database engine for the high-throughput time-series audit logging component.Cevap
  4. D
    Implement Customer-Supplied Encryption Keys (CSEK) managed directly within application code to encrypt the transactional database storage.

Cevap

The architect should choose Cloud SQL for PostgreSQL configured with High Availability (HA) and Customer-Managed Encryption Keys (CMEK) for the transactional engine, and Cloud Bigtable for the high-throughput time-series audit logging component.
For single-region relational workloads requiring SQL compliance, automatic zonal failover, and key management integration, Cloud SQL configured with HA and CMEK is the cost-effective solution. For high-volume append-only time-series data needing low-latency writes and range queries, Cloud Bigtable provides optimized NoSQL performance.

Adım Adım Çözüm

1
Analyze the transactional database requirements
The transactional workload needs full SQL compliance, single-region high availability, and Cloud KMS CMEK integration.
Cloud SQL with HA delivers zonal failover and CMEK support at lower cost than Cloud Spanner for localized single-region applications.
2
Analyze the audit log workload requirements
The audit logging workload requires append-only time-series writes with sub-10ms latency and key-range scans.
Cloud Bigtable is optimized for scalable, low-latency NoSQL time-series data streams.
