Zorluk: OrtaSelecting and Designing Storage and Database Resources

A regional European gaming studio is designing the persistent database backend for an online multiplayer game's player profile and inventory management system. The database must run in a single Google Cloud region (europe-west3), support strict ACID transactional consistency, provide automated regional failover across multiple availability zones, and handle up to 15,000 IOPS during peak events. The team wants to avoid unnecessary architectural complexity and operational cost. Which storage and database architecture should you recommend to meet these requirements?

  1. Deploy a Cloud SQL for PostgreSQL instance with High Availability (HA) enabled across primary and standby zones within the region.Cevap
  2. B
    Provision a multi-region Cloud Spanner instance with global replication to handle all transactional inventory operations.
  3. C
    Use a Google Cloud Transfer Appliance cluster connected to Cloud Storage to handle real-time transactional reads and writes.
  4. D
    Configure a Cloud Bigtable cluster utilizing Customer-Supplied Encryption Keys (CSEK) to maintain strict transactional consistency across player profiles.

Cevap

The recommended solution is deploying a Cloud SQL for PostgreSQL instance configured for High Availability (HA) within the single target region.
Deploying Cloud SQL for PostgreSQL with High Availability (HA) is the optimal choice. Cloud SQL provides native relational database capabilities with ACID compliance, and its HA option automatically replicates data synchronously to a standby instance in a secondary zone within the same region (europe-west3), ensuring quick failover while keeping costs and operational overhead aligned with single-region requirements.

Adım Adım Çözüm

1
Analyze the functional database requirements
The application requires ACID compliance for player profiles and inventory, single-region deployment in europe-west3, and high availability across zones.
Relational data modeling with transactional guarantees is required for monetary or inventory operations.
2
Evaluate GCP database services based on scale and region constraints
Cloud SQL satisfies single-region relational database requirements cost-effectively. Cloud Spanner is intended for globally distributed workloads requiring cross-region consistency.
Choosing Spanner for a single-region deployment incurs unnecessary cost and architectural complexity.
3
Verify high availability configuration
Enabling High Availability (HA) on Cloud SQL provisions a synchronous standby instance in a second zone within the same region, providing automatic failover.
This satisfies the multi-zone availability requirement without requiring cross-region infrastructure.
