Storage Lifecycle Cost
Old exam scans are rarely read. Move them to cheaper tiers with lifecycle rules and compare the monthly bill.
🎯 You will learn to
- Know hot, cool and archive tiers
- Write lifecycle rules
- Weigh retrieval cost
📘 Guided lab
This mission is a guided walkthrough: follow the steps on your own computer or practice account. The in-browser simulator for it is planned for a later release.
✅ Steps & checkpoints
🗺️ Storage tiers by age
Lifecycle rules move objects to cheaper tiers as they age and delete them after the retention period.
The 2D diagram shows the exact flow, ports and trust boundaries. The 3D scene is a concept view of the same parts; packets travel along the same arrows.
🤔 Think about it
When is archive storage more expensive than it looks?
🛡️ Safety & cost
Mock cloud: no account, no resources, no cost.
