Storage Tiering

Concepts: paDataLake

What They Want to Hear 'Not all data is accessed equally. I tier data by access pattern: hot (SSD, recent days/weeks, most expensive), warm (standard S3, recent months), cold (Glacier, historical years, cheapest). This alone can cut storage bills by 60-80% because the 80/20 rule applies: 80% of queries touch 20% of data.'
