Why DRaaS Can’t Ensure Continuous Availability (and What You Can Do)

Why DRaaS Can’t Ensure Continuous Availability (and What You Can Do)

According to Forrester Research, 40 percent of organizations have adopted disaster recovery as a service (DRaaS) and another 24 percent plan to do so. As a cloud-based managed service, DRaaS allows organizations to alleviate the costs and complexity of deploying and managing a disaster recovery site on their own.

However, organizations with mission-critical applications cannot take advantage of DRaaS benefits, and still others are using DRaaS without understanding the risks of doing so. The problem is that current DRaaS solutions cannot guarantee continuous availability of their critical applications. Once a disaster occurs, data loss is guaranteed—along with protracted recoveries, prolonged downtime, higher reconciliation costs, compliance breaches, and other untenable risks.
Here’s why….

With DRaaS, Synchronous Replication Isn’t Possible

With DRaaS, the organization manages its primary data center on premises, and the cloud service provider (CSP) runs the secondary DR site in the cloud. This site must be located far enough away from the primary site to avoid disruption in the event of a regional disaster; however, this distance creates a serious challenge. It makes synchronous replication practically impossible because it increases latency to unacceptable levels and requires the use of high-cost (and, therefore, economically unfeasible) communication lines. Without synchronous replication, data loss—along with application disruption—is guaranteed in the event of a disaster.

Even if a CSP’s service level agreement (SLA) assures high availability, there is no way to guarantee high availability in a DRaaS environment. Depending on the amount of data lost in a disaster, the recovery time (i.e., RTO) can skyrocket as the IT team scrambles to restore applications to consistency and do other tasks associated with data loss.

Axxana’s Phoenix Takes the Risk out of Cloud

The good news is that there is now a solution for ensuring the continuous availability of mission-critical applications in a DRaaS environment. Axxana’s Phoenix for Oracle on Microsoft Azure makes zero data loss and high availability the norm at any distance—without the costly communication lines or the long latency associated with synchronous replication. Using Axxana’s Phoenix, organizations can move to the cloud without incurring the risks associated with DRaaS. They gain the fastest recovery and highest application availability possible, while alleviating the costs and complexity associated with implementing, staffing, and maintaining a standby DR site on their own. Available for a low monthly fee, Axxana’s Phoenix for Oracle on Microsoft Azure also helps organizations control and predict operational expenditures.
