Difficulty: EasyPlanning Compute Engine Resources and Machine Types

A cloud engineer is designing the Compute Engine architecture for an enterprise web service that must run continuously 24/7 without interruption. The application requires a customized resource allocation of exactly 6 vCPUs and 27 GB of RAM to operate efficiently. Which Compute Engine configuration strategy should be selected for this workload?

  1. Provision standard Compute Engine instances with a Custom machine type using standard (non-spot) VMs.Answer
  2. B
    Provision Spot VMs with a Custom machine type to minimize baseline compute costs.
  3. C
    Deploy the web service onto Google Kubernetes Engine Autopilot nodes requiring custom OS kernel modifications.
  4. D
    Refactor the backend web service into single-purpose snippets and host them on Cloud Functions for continuous execution.

Answer

Provision standard Compute Engine instances with a Custom machine type using standard (non-spot) VMs.
Choosing standard Compute Engine VMs configured with a Custom machine type satisfies both the specific non-standard vCPU/memory ratio (6 vCPUs and 27 GB RAM) and the requirement for continuous 24/7 uptime without risk of unexpected preemption.

Step-by-Step Solution

1
Analyze workload availability requirements.
The application requires continuous 24/7 availability without interruption.
Spot/Preemptible VMs can be reclaimed by GCP at any time and are not suitable for non-fault-tolerant continuous services.
2
Analyze resource sizing requirements.
The application needs a specific non-standard ratio of 6 vCPUs and 27 GB RAM.
Custom machine types allow tailoring CPU and memory precisely to workload needs, preventing waste from overprovisioned predefined sizes.
