Store in Hot tier initially. Move to Cool tier after 30 days. Move to Archive tier after 365 days.

Azure Blob Storage offers different access tiers optimized for cost. The Hot tier has the highest storage cost but lowest access cost, ideal for the first 30 days. The Cool tier has lower storage costs but higher access costs, ideal for data older than 30 days. The Archive tier has the lowest storage cost but highest retrieval cost and latency (hours), making it perfect for the 1-to-7 year compliance retention period. Lifecycle management policies can automate these transitions.

Common mistakes

Skipping the Cool tier and going straight to Archive, which can result in massive rehydration costs if data is accessed.
