Disaster recovery is changing in IT, and alongside this change is a host of new considerations and risks. This post by Bob Violino looks at 4 tech trends that are changing the way IT does DR — starting with cloud services. Cloud services. Citing samples of scattered data distributed through cloud services, Violino shows how companies can save time and money by having data on servers that only “spin up” when needed. The post goes on, using the insights of Ariel Silverstone, former CISO of Expedia, who explains another changing element (virtualization) has some draw backs:
On the downside, the popularity of virtualization has led to virtual machine sprawl at many organizations, which can make DR more complex. “Companies have the [virtualization]structure in place that gives them the ability to create many more images, including some they do not even know about or plan for,” Silverstone says. “And they can do so very quickly.” Another potential negative is that virtualization might give organizations a false sense of security. “People may fail to plan properly for disaster recovery, assuming that everything will be handled by virtualization,” Silverstone says. “There are certain machines that for various reasons are not likely to be virtualized, so using virtualization does not replace the need for proper disaster recovery planning and testing.”
The other two trends are the use of mobile devices and social networking. Both allow for IT workers and the business to communicate if, let's say, a snowstorm prevents anyone from getting to the office. Whereas it once took weeks to get a company back on its feet, the proliferation of mobile tech and social media has provided a way to start working on recovery even before the natural event itself is over.
