Vertical Scaling

Foundations ✓ → Platform ✓ → Ops → Projects

Ops · 3 — DevOps, security, scale · ~10 min · Cloud — Scalability & Distributed Systems

What is this?

Vertical scaling increases CPU, RAM, or disk on existing instances — simpler but has upper limits.

Why should you care?

CloudVerse legacy monolith DB temporarily gets a larger SKU before sharding project completes.

See it live — copy this example

Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.

# Azure CLI — resize VM (CloudVerse batch worker)
az vm resize \
  --resource-group rg-cloudverse-batch \
  --name vm-erp-worker \
  --size Standard_D8s_v5
# Downtime may occur — plan maintenance window

What happened?

Good for quick relief on monoliths; bad as only long-term strategy.
Cloud limits max VM size per family.

Practice next

Baseline CPU/RAM on one VM.
Resize in maintenance window.
Re-run benchmark.
Compare vertical vs horizontal cost for same throughput.
Enable memory metrics before resize.

Remember

Bigger machine, same count. Quick fix. Plan ceiling.

CloudVerse ERP worker

Nightly job OOM on D4.

Outcome: D8 finishes batch; team plans queue-based refactor.
