Move from Three DCs to Two
Concerned about meeting SLAs for Tier 0 and Tier 1 applications? With Axxana’s Phoenix for Oracle, two-data-center solutions are more resilient, more efficient, and more cost-effective than traditional three-data-center solutions. Why compromise?
Rapid Recovery. Continuous Application Availability. Lower Costs.
Organizations operating Tier 0 and Tier 1 databases need to ensure continuous application availability in the event of a disaster. Traditional business continuity and disaster recovery solutions often revolve around synchronous replication in a three-data-center topology; however, these solutions come at a high price in terms of dollars and risk.
The bottom line is that three-data-center solutions cannot enable continuous application availability because they cannot guarantee zero data loss. In fact, they pose a number of risks and challenges:
- Delayed recovery and unacceptable downtime due to data loss and time-consuming reconciliation measures
- Vulnerability to data loss caused by synchronous replication failures between the primary data center and the nearby, synchronous replication facility (in the event of regional disasters or rolling disasters)
- High costs of the nearby data center facility that hosts the synchronous replication instance
- High costs of fiber optic lines connecting the primary data center and the nearby synchronous replication facility
- Operational complexity
Whether on-prem or cloud-based, Axxana’s Phoenix for Oracle is a cost-effective, continuous application availability solution that eliminates the need for a three-data-center topology and its associated risks. Using Axxana’s Phoenix to guarantee zero data loss, your organization can ensure extremely high availability for mission-critical applications and meet stringent SLAs—all at a fraction of the cost of traditional solutions.
Axxana’s Phoenix fulfills the functions of a nearby synchronous data center right at the primary site, continuously protecting yet-to-be-replicated data. Because a nearby data center is not needed, the risk of a nearby synchronous site failing (e.g., due to a power outage or downed communication lines) no longer exists—even in regional or rolling disasters. Zero data loss is guaranteed in any disaster, increasing the probability of successful failover and continuous application availability.
Eliminates High-Cost Lines
Because there is no need for a nearby synchronous data center, there is no need for costly fiber-optic replication lines. Your organization can use low-cost IP lines for asynchronous replication across the large distance between the primary and remote DR data center.
Reduces Operational and Recovery Costs
The Phoenix-based architecture does not require a third, nearby data center, so it costs a lot less to implement. Savings span across multiple cost centers, including head count, real estate, utilities, equipment, and communications. In addition, because Axxana’s Phoenix ensures zero data loss recovery, there is no missing data to reconcile. Labor associated with data reconciliation becomes a line item of the past.
The Axxana Phoenix solution trades a complex three-data-center topology for a simple two-data-center deployment. That means one less physical plant, one less HR staffing headache, and one less communications infrastructure to manage. And when disaster strikes, it also means you can skip reconciliation (because data is never lost) and move straight to failover.
