Technical Note: Enabling Continuous Availability in DR Environments

Technical Note: Enabling Continuous Availability in DR Environments

The goal of continuous availability, as stated by Oracle, is to “hide planned maintenance, unplanned outages, and load imbalances of the database.” Oracle has been enhancing its continuous availability capabilities from release to release with technologies like Fast Application Notification (FAN), Transparent Application Failover (TAF), and (as of Oracle Database 18c) Transparent Application Continuity to enable organizations to develop applications without having to deal with failure handling.

Achieving Continuous Application Availability with Zero Data Loss  as a Service

Achieving Continuous Application Availability with Zero Data Loss as a Service

While some organizations are adopting disaster recovery as a service (DRaaS), many organizations still have their hands tied when it comes to using the hybrid cloud to protect business-critical data and ensure business continuity. Still others are offloading disaster recovery operations to cloud service providers without fully understanding the risks of doing so. The problem is, current DRaaS solutions cannot guarantee zero data loss and continuous availability of their critical applications; once a disaster occurs, data loss is guaranteed—along with protracted recoveries, downtime, and other untenable risks. The good news is that there is now a solution. Axxana’s Phoenix for Oracle on Microsoft Azure raises the bar for DRaaS by making zero data loss and continuous availability the new norm at any distance—and while alleviating the costs and complexity of implementing, staffing, and maintaining a standby DR site.

Why Disasters Happen

Why Disasters Happen

This research explores the root causes of why disasters happen, and the factors which affect recovery from a disaster. It looks in detail at the problem of loss of Data-in-Flight, and how this affects recovery.

The Business Impact of Eliminating Loss of Data-in-Flight

The Business Impact of Eliminating Loss of Data-in-Flight

The cost of downtime due to data loss and unplanned outages at Global 2000 companies ranges from 5-8% of revenue. Digital initiatives and the increasing value and importance of data elevates the imperative to address data loss. Organizations should especially focus on vulnerabilities in mission critical systems with a specific emphasis on eliminating the loss of data in-flight. Doing so can cut the cost of downtime in half over a four-year period. This research focuses on how zero loss of data-in-flight leads to certainty of data integrity. This in turn leads to simplified recovery and significantly reduces the chances of disasters.
