What is Tiering?

Tiering, in the context of data storage and management, refers to the practice of assigning different categories (tiers) to data based on factors such as frequency of access, performance requirements, and cost. More frequently accessed, performance-critical data is stored on faster, more expensive storage media (e.g., SSDs), while less frequently accessed, archival data is stored on slower, less expensive storage media (e.g., HDDs or cloud storage). This approach optimizes performance and cost-effectiveness by placing data where it is most appropriate based on its usage patterns.
