Role: Data & Storage

Purpose: Maintain the integrity, availability, and performance of data across the infrastructure.

Responsibilities:

• Provide standardized storage interfaces (e.g., CSI) for application persistence.
• Manage data replication and physical distribution across failure domains.
• Enforce data consistency models suitable for various workload types.
• Oversight of data lifecycle management, including snapshots and retention.

Guarantees:

• Data remains available and consistent despite individual hardware failures.
• Protection is provided against silent data corruption through checksums and scrubbing.
• Storage performance is maintained according to application requirements.

Out of Scope:

• Application-specific database schemas and indexing.
• Long-term offsite archival and backup (handled by Backup & Disaster Recovery).
• Management of transient, non-persistent application data.
