How to use GCP Compute Engine

· Category: Cloud Computing

Short answer

Compute Engine is Google Cloud's IaaS offering for running VMs with flexible configurations and pricing.

Steps

  1. Create an instance:
gcloud compute instances create my-vm --zone=us-central1-a
  1. Choose machine type (predefined or custom).
  2. Configure boot disk and firewall rules.
  3. Connect via SSH:
gcloud compute ssh my-vm --zone=us-central1-a

Tips

  • Custom machine types let you choose exact vCPU and memory ratios.
  • Preemptible VMs offer up to 80% discounts for fault-tolerant workloads.
  • Use instance templates and managed instance groups for auto-scaling.

Common issues

  • Quota limits may block creation; request increases in advance.
  • Firewall rules are project-wide by default; use network tags for granularity.
