Billing, Free Tiers, and Cost Awareness

You pay for usage meters

Providers meter compute time, storage gigabytes, data transfer, API requests, and managed service hours. Idle resources with attached disks or public IPs can still cost money. Always know what remains after you "finish" a tutorial.

Treat free tiers as training wheels

Free tiers and trial credits are limited by time, product, or monthly quotas. They are excellent for learning, but production planning should assume normal pricing. Set budget alerts on day one.

Build cost habits early

• Tag resources with project and owner
• Shut down lab VMs when not in use
• Prefer small instance sizes while learning
• Watch egress (outbound data) fees
• Delete load balancers, IPs, and disks you no longer need

Open the cost tools

Each cloud has a billing console; CLIs can also surface account or project context tied to billing.

# Confirm which account/project will be billed
aws sts get-caller-identity
az account show --query '{name:name, id:id}' -o table
gcloud config list
