Zorluk: OrtaPlanning Compute Engine Resources and Machine Types

A retail analytics company is planning its Google Compute Engine infrastructure for two distinct application services:
1. An online, memory-intensive analytics engine requiring large RAM allocations, predictable baseline CPU performance, and continuous 24/7 availability over a multi-year timeframe.
2. A stateless data ingestion pipeline that processes incoming messages asynchronously from a queue and can recover gracefully if individual instances are terminated unexpectedly.

Which TWO deployment strategies should the cloud engineer select to meet operational requirements while optimizing cost efficiency? (Select 2 answers.)

  1. Provision High-Memory or Memory-Optimized VM instances coupled with Committed Use Discounts (CUDs) for the 24/7 analytics engine.Cevap
  2. Provision Spot Virtual Machines for the stateless data ingestion pipeline to minimize compute costs.Cevap
  3. C
    Provision Spot Virtual Machines for the 24/7 analytics engine to achieve maximum compute discount rates.
  4. D
    Deploy the memory-intensive analytics engine to Cloud Functions to automatically eliminate VM infrastructure management.

Cevap

The cloud engineer should select provisioning High-Memory or Memory-Optimized VM instances with Committed Use Discounts (CUDs) for the steady-state analytics engine, and provisioning Spot Virtual Machines for the fault-tolerant data ingestion pipeline.
Provisioning High-Memory or Memory-Optimized instances with Committed Use Discounts fulfills the high-RAM 24/7 availability requirements of the analytics engine while securing deep steady-state discounts. Provisioning Spot VMs for the stateless data ingestion pipeline leverages maximum discounts for a workload that easily handles sudden instance terminations.

Adım Adım Çözüm

1
Analyze the operational profile of the analytics engine workload.
Determined to require high RAM allocations and continuous 24/7 multi-year uptime.
High-Memory / Memory-Optimized machine types satisfy the resource ratio, while Committed Use Discounts (CUDs) minimize costs for steady 24/7 utilization.
2
Analyze the operational profile of the data ingestion pipeline workload.
Determined to be stateless, asynchronous, queue-based, and interruption-tolerant.
Workloads capable of handling abrupt terminations benefit most from the low pricing of Spot Virtual Machines.
3
Evaluate and eliminate anti-pattern architecture proposals.
Rejected using Spot VMs for the continuous analytics engine and Cloud Functions for the memory-intensive engine.
Spot VMs introduce preemption risk to continuous services, while Cloud Functions cannot sustain long-running, memory-heavy database workloads.

Anahtar Kavram

Matching Compute Engine machine families and purchasing models (Spot VMs vs. CUDs) to workload memory demands and fault tolerance.
