Zorluk: OrtaPlanning Compute Engine Resources and Machine Types

A financial technology company is designing the Google Cloud Compute Engine resource strategy for two distinct backend services:
1. A fault-tolerant, stateless batch risk analytics service that processes asynchronous job queues.
2. A mission-critical relational database service requiring continuous 24/7 availability with predictable capacity.

Which of the following compute provisioning strategies should the cloud engineer implement? (Select TWO.)

  1. Provision Spot VMs for the fault-tolerant batch risk analytics workload to minimize compute costs.Cevap
  2. Purchase Committed Use Discounts (CUDs) for the vCPU and memory footprint of the continuous relational database workload.Cevap
  3. C
    Deploy the mission-critical relational database on Spot VMs to optimize cost efficiency during off-peak hours.
  4. D
    Rely on automatic Sustained Use Discounts (SUDs) instead of Committed Use Discounts to maximize savings for the 24/7 database workload.

Cevap

Provision Spot VMs for the fault-tolerant batch risk analytics workload, and purchase Committed Use Discounts (CUDs) for the continuous relational database workload.
The correct strategy combines Spot VMs for the fault-tolerant risk analytics workload and Committed Use Discounts (CUDs) for the 24/7 database. Spot VMs lower compute costs substantially for stateless workloads that tolerate preemption. For steady 24/7 database workloads, purchasing a 1-year or 3-year Committed Use Discount yields maximum cost savings while preserving continuous instance availability.

Adım Adım Çözüm

1
Analyze the fault-tolerant batch risk analytics service requirements.
Identified that the service is stateless and queue-based, meaning job failures or instance preemptions can be retried without data corruption.
Spot VMs are designed for stateless, fault-tolerant workloads and provide up to 60-91% cost reductions.
2
Analyze the relational database service requirements.
Identified that the service requires uninterrupted 24/7 operation with steady, predictable vCPU and memory resource consumption.
Committed Use Discounts (CUDs) provide the deepest pricing discounts for steady-state baseline workloads requiring 1-year or 3-year commitments without node preemption risks.
