Zorluk: OrtaPlanning Database Options and Persistent Disk Types

An enterprise logistics company is migrating its fleet monitoring application to Compute Engine on Google Cloud. The system architecture has two key storage requirements:

1. A fully managed NoSQL database capable of ingesting high-throughput, low-latency time-series GPS location telemetry from tens of thousands of delivery vehicles.
2. Extremely high IOPS local block storage attached to processing virtual machines to serve as high-speed, temporary scratch space for processing incoming data streams, where data loss upon instance termination is acceptable.

Which TWO Google Cloud database and block storage options should the engineering team select? (Select TWO.)

  1. Cloud Bigtable for storing high-throughput, low-latency GPS telemetry dataCevap
  2. Local SSD attached to Compute Engine instances for temporary, high-IOPS stream transformation scratch disk spaceCevap
  3. C
    Cloud SQL for PostgreSQL for storing high-throughput, low-latency GPS telemetry data
  4. D
    Standard Persistent Disk (pd-standard) attached to Spot VMs for high-IOPS temporary stream transformation scratch disk space

Cevap

The correct architecture requires selecting Cloud Bigtable for the time-series telemetry ingestion and Local SSD for high-performance temporary VM scratch space.
The solution requires Cloud Bigtable because it is engineered for high-volume, low-latency NoSQL time-series data such as vehicle GPS tracking. Local SSD is the ideal choice for ephemeral scratch space requiring maximum IOPS, as it is physically attached to the hypervisor host and yields superior performance for scratch workloads.

Adım Adım Çözüm

1
Analyze the database requirement for high-throughput time-series GPS location telemetry.
Cloud Bigtable provides scalable, low-latency NoSQL storage specifically optimized for time-series and IoT telemetry data.
Relational databases like Cloud SQL do not scale as efficiently for massive, sustained single-key time-series write workloads.
2
Analyze the block storage requirement for temporary stream transformation scratch disk space requiring ultra-high IOPS.
Local SSD provides sub-millisecond latency and maximum throughput/IOPS by physically attaching to the VM host server, accepting data loss upon VM termination.
Standard Persistent Disks rely on network-attached HDD storage with substantially lower IOPS limits.
