Zorluk: OrtaDesigning Infrastructure for Technical Requirements and High Availability

An autonomous maritime cargo logistics company is deploying its fleet monitoring platform on Google Cloud. The architecture requires a private hybrid connection between their central port data center and Google Cloud capable of handling a continuous throughput of 8 Gbps with enterprise SLAs. Additionally, the transactional telemetry engine requires a database deployment in a single region that guarantees automatic multi-zone failover with zero Recovery Point Objective (RPO). Which TWO architectural decisions should the cloud architect implement to meet these high availability and technical requirements?

  1. Provision a 10 Gbps Dedicated Interconnect circuit with redundant interconnect attachments deployed across two distinct edge availability domains.Cevap
  2. Configure a regional Cloud SQL instance with High Availability (HA) enabled, utilizing primary and standby instances placed in separate zones with synchronous storage replication.Cevap
  3. C
    Establish multiple HA VPN tunnels over the public internet routed dynamically using BGP to handle the 8 Gbps hybrid traffic.
  4. D
    Deploy Compute Engine Managed Instance Groups (MIGs) and set autoscaling rules based exclusively on CPU utilization metrics.
  5. E
    Provision a zonal Cloud SQL database instance backed by hourly automated snapshots to recover in an alternate zone upon failure.

Cevap

The platform requires Dedicated Interconnect with redundant attachments across two edge availability domains to reliably support 8 Gbps private hybrid bandwidth, along with a regional Cloud SQL instance configured for High Availability across two zones to ensure automatic failover and zero RPO synchronous replication.
To satisfy high throughput (>3 Gbps) and SLA requirements for hybrid networking, Dedicated Interconnect with redundant attachments across separate edge availability domains is required. For database high availability with zero RPO, a regional Cloud SQL instance with High Availability (HA) enabled provides synchronous multi-zone storage replication and automated failover.

Adım Adım Çözüm

1
Evaluate hybrid network connectivity requirements.
The requirement specifies private 8 Gbps throughput with enterprise SLAs.
HA VPN maxes out at 3 Gbps per tunnel over public internet. Dedicated Interconnect provides 10 Gbps physical links with dedicated SLAs and redundant edge availability domains.
2
Evaluate relational database high availability requirements.
The requirement demands a single-region database with zero RPO and automatic multi-zone failover.
Cloud SQL HA mode uses regional persistent disk storage with synchronous replication across two zones in the same region, ensuring zero data loss (RPO = 0) and automated failover.
