Section 1 - Instruction

Congratulations on mastering storage architectures and schema design! Now let's tackle the final challenge: building systems that perform well without breaking the bank.

Storage costs can spiral out of control quickly, but smart optimization strategies keep them manageable while maintaining performance.

What's one reason storage costs might grow faster than expected?

Section 2 - Instruction

Here's the reality: not all data needs lightning-fast access. Your last week's sales data needs instant queries, but sales from 2019 can wait a few extra seconds.

This insight unlocks massive cost savings through strategic storage tiering.

Which data would you prioritize for fastest access: yesterday's orders or last year's orders?

Section 3 - Instruction

Storage tiering organizes data by access frequency. Hot storage serves frequently-accessed data with premium performance. Cold storage handles infrequent access at lower cost.

Archive storage provides the cheapest option for compliance and backup data that's rarely accessed.

What type of storage tier would be best for daily dashboard data?

Section 4 - Instruction

Most cloud platforms offer automatic tiering based on access patterns. AWS S3 Intelligent-Tiering moves data between tiers automatically, while Azure and Google Cloud offer similar services.

This eliminates manual tier management while optimizing costs based on actual usage patterns.

Engagement Message

Why would automatic tiering be better than manually moving data between tiers?

Section 5 - Instruction

Lifecycle policies automate data movement and deletion based on age or access patterns. Set rules like "move to cold storage after 30 days" or "delete after 7 years."

This ensures compliance requirements are met while preventing unnecessary storage costs from accumulating.
