Zorluk: KolayCapacity Planning and Infrastructure Workload Scaling Optimization

An enterprise plan involves migrating a legacy batch-processing platform requiring 500 high-capacity Compute Engine Virtual Machines to a single target GCP region within a strict maintenance window. Prior to executing the migration script, which proactive capacity planning step must the cloud architect take to prevent deployment failure due to resource limits?

  1. Audit existing project quotas and submit a regional quota increase request for Compute Engine CPU cores and instances prior to deployment.Cevap
  2. B
    Migrate all legacy virtual machines directly into Google Kubernetes Engine (GKE) node pools to bypass Google Cloud regional quota requirements.
  3. C
    Proceed with deploying all 500 instances immediately and rely on default regional quotas to automatically scale up capacity upon demand.
  4. D
    Configure an instance group autoscaling policy based strictly on CPU utilization to override project resource limits.

Cevap

Audit existing project quotas and submit a regional quota increase request for Compute Engine CPU cores and instances prior to deployment.
The correct answer emphasizes requesting regional quota increases in advance. Google Cloud enforces project resource quotas to prevent unexpected consumption and protect infrastructure. When deploying large workloads (such as 500 Compute Engine instances), architects must verify quota availability and request increases early to prevent API provisioning failures.

Adım Adım Çözüm

1
Calculate required compute resources
Determine the exact CPU, memory, and instance count needed in the target region (500 VMs).
Accurate resource totals are required to evaluate current quota headroom.
2
Review current regional quotas in Google Cloud Console
Identify any gap between default quota limits and required capacity.
GCP projects come with default quotas that restrict compute deployment size until explicitly raised.
3
Submit a quota increase request before deployment
Obtain approval and allocated quota capacity prior to launching automated migration scripts.
Quota increases require evaluation and processing time by GCP, preventing quota enforcement errors during execution.
