Oracle’s HA Service Level Tiers

This white paper on HA Best Practices and DBaaS is pretty interesting, especially for its definitions of “HA Service Level Tiers”:

 

BRONZE

  • Single-instance database.
  • DR: Requires restore from the last backup, potential for data loss.

SILVER

  • RAC database.
  • DR: Requires restore from the last backup (with potential for data loss).

GOLD

  • RAC database with Data Guard and GoldenGate.
  • DR: Real-time failover to standby database (with zero or near-zero data loss).

PLATINUM

  • RAC database with Data Guard, GoldenGate and Application Continuity.
  • DR: In-flight transactions are preserved (with zero data loss).

 

The “Platinum” service level, naturally, requires some seriously impressive kit. I wonder what “Titanium” or “Palladium” will eventually turn out to need 🙂
