1. Tiered Storage
Definition
Tiered Storage is a data management strategy that places data on different types of storage media based on access frequency, performance requirements, and cost efficiency. It is designed to optimize resource utilization by matching the storage medium’s capabilities with the business value and activity level of the data.
This approach is especially relevant in hybrid cloud, enterprise IT, and cloud-native applications, where vast amounts of data must be retained but only a portion is accessed regularly.
Why Tiered Storage Matters
- Cost Optimization: Reduces overall storage costs by avoiding unnecessary use of high-performance (and expensive) storage for infrequently accessed data.
- Performance Alignment: Keeps frequently accessed data on high-speed storage to ensure performance-sensitive applications are not bottlenecked.
- Lifecycle Management: Supports policies that automatically move data across storage tiers over time (e.g., AWS S3 Lifecycle Rules, Azure Blob Storage lifecycle policies).
- Compliance: Allows long-term archival of data to meet regulatory requirements while minimizing cost.
