What is Cloud Storage Tiers?
Different storage classes offered by cloud providers, optimized for varying access patterns from frequent to archival use.
Cloud providers offer multiple storage tiers with different cost and performance characteristics. Hot/Standard storage provides immediate access for frequently used data. Warm/Infrequent Access storage reduces costs for data accessed monthly. Cold/Archive storage (AWS Glacier, Azure Archive) offers the lowest cost for rarely accessed data but with retrieval delays of minutes to hours. Intelligent tiering automatically moves objects between tiers based on access patterns. Choosing the right tier can reduce storage costs by 50-90%. Lifecycle policies automate transitions — for example, moving logs to cold storage after 90 days and deleting after one year.
