What is this?

Cloud economics is about unit cost, elasticity, and waste — not only the monthly bill number.

Why should you care?

CloudVerse finance cares about cost per order and idle resources.

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.

# Unit economics sketch
# cost_per_order = (compute + db + egress) / orders
# Waste: idle VMs, unattached disks, over-provisioned SQL
# Fix: rightsizing, autoscaling, reserved/savings plans

What happened?

Egress and storage grow silently.
Tag resources for showback.
Optimize after you measure.

Practice next

Define one unit metric.
List two waste types.
Enable billing tags in lab.
Estimate egress for a CDN miss.
Turn off a lab VM overnight.

Remember

Unit cost. Find waste. Tags + rightsizing.

CloudVerse cost per order

Finance asks for unit cost.

Outcome: Team tags and rightsizes first.
