To implement a hot and cold data tiered storage strategy in cloud storage, you need to classify data based on access frequency and importance, then store it in appropriate storage tiers to optimize cost and performance.
-
Define Data Classification Criteria:
- Hot Data: Frequently accessed data (e.g., real-time analytics, active user files).
- Cold Data: Infrequently accessed data (e.g., archived logs, compliance records).
-
Choose Storage Tiers:
- Hot Tier: High-performance storage with low latency (e.g., Tencent Cloud COS Standard).
- Cold Tier: Cost-effective storage with higher access latency (e.g., Tencent Cloud COS Infrequent Access or Archive).
-
Automate Data Movement:
Use lifecycle policies to automatically transition data between tiers. For example:
- Move files older than 30 days from COS Standard to COS Infrequent Access.
- Archive files older than 90 days to COS Archive.
-
Example Use Case:
A video streaming platform stores recently uploaded videos in COS Standard (hot tier) for fast playback. After 30 days of low access, videos are moved to COS Infrequent Access (cold tier) to reduce costs.
-
Leverage Tencent Cloud Services:
- COS (Cloud Object Storage): Supports tiered storage with Standard, Infrequent Access, and Archive tiers.
- CAM (Cloud Access Management): Ensures secure access control for different data tiers.
- SCF (Serverless Cloud Function): Automates data tiering via event-driven triggers.
This strategy ensures cost efficiency while maintaining performance for critical workloads.
