How do you configure blob tiers (hot/cool/archive)?

Short answer: Blob tier determines cost and access latency. Can be set during upload or later: await blobClient.SetAccessTierAsync(AccessTier.Cool); Hot: Frequently accessed Cool: Infrequent access Archive: Rarely accessed

Real-world example (ShopNest)

Product images upload to Azure Blob Storage; the DB only stores the blob URL.

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
