The more Big Data enterprises continue to amass, the more potential risk is involved. It would be one matter if it was simply raw material without any clearly defined meaning; however data analytics tools—combined with the professionalism of tech-savvy employees—allow businesses to harvest profit-driving, actionable digital information.
Whether the risk is from a a cyber-criminal who gains access to a database or a storm that cuts power, it’s essential for enterprises to have a solid disaster recovery plan in place. Because on-premise data centers are prone to outages in the event of a catastrophic natural event, cloud servers provide a more stable option for companies requiring constant access to their data. Numerous deployment models exist for these systems, and most of them are constructed based on how users interact with them.
How the cloud can promote disaster recovery
According to a report conducted by InformationWeek, only 41 percent of respondents to the magazine’s 2014 State of Enterprise Storage Survey stated they have a disaster recovery (DR) and business continuity protocol and regularly test it. Although this finding expresses a lack of preparedness by the remaining 59 percent, the study showed that business leaders were beginning to see the big picture and placing their confidence in cloud applications.
The source noted that cloud infrastructure and Software-as-a-Service (SaaS) automation software let organizations deploy optimal DR without the hassle associated with a conventional plan. Traditionally, companies backed up their data on physical disks and shipped them to storage facilities. This method is no longer workable because many enterprises are constantly amassing and refining new data points. For example, Netflix collects an incredible amount of specific digital information on its subscribers through its rating system and then uses it to recommend new viewing options.
The news source also acknowledged that the issue isn’t just about recovering data lost during the outage, but about being able to run the programs that process and interact with that information. In fact, due to the complexity of these infrastructures, many cloud hosts offer DR-as-a-Service.
Figuring out the right architecture
Bill Kleyman, a contributor to Data Center Knowledge, noted that executives also need to realize these systems aren’t indestructible, although they’re generally more secure than most conventional databases. The businesses that often report problems with their deployments are the ones that neglected to craft a solid DR and business continuity framework. Those that are prepared for the disaster consider the following cloud server options as they are applicable to their operational requirements:
- DRaaS is a pay-as-you-go model offered by vendors or database specialists, allowing enterprises to either work around an environment that requires no downtime or specify which applications should be recovered in the event of an emergency.
- Backup-based restoration replicates all data, applications, and other services to a cold virtual machine.
- DR driven by workload requirements doesn’t require the entire architecture be restored. Although stored in the cloud, necessary features can be mirrored live or provided to users in the event of an emergency.
- Warm or cold site DR allows some downtime to occur and is often the preferred option for a complex public cloud network.
- Finally, active, or hot site configurations encounter the least amount of downtime. The system is always active, which can prove to be an expensive, but necessary option, depending on the needs of the company.
The fact that an entire sub-industry has been created as the result of demand for quality DR and business continuity is a sign that techniques will continue to improve in the future. As more companies continue to adopttechnologies, the above methods are sure to encourage further investigation and investment.
