Enabling Cloud Confidence

A week ago I wrote about the Sidekick disaster and how events like that just keep doubts growing, pushing the wholesale adoption of the Cloud further away. This doubt has made it into the mainstream media, where it will taint the opinions of potential cloud users, both consumer and commercial. We at ZeroNines think we have the solution that will enable the cloud to perform as it needs to.

The core problem with outages is not the existence of hazards that can damage servers and knock elements of a network (cloud or otherwise) offline. Storms, fires, and equipment failure will always happen and there is no way to eliminate them. The real problem is the reliance of cloud providers on obsolete failover-based recovery paradigms that simply can’t maintain continuity when disaster does strike.

L.A. Times columnist David Sarno perfectly sums up the cloud’s tenuous situation in his October 18 article “Still hazy on cloud computers' security” [source]. “A series of incidents involving cloud computing over the last several months has poked holes in the hype bubble, raising questions about the cloud's dependability -- and whether it's ready for use by a broader group of workers and businesses.” He is right on target.

Meeting the Need to Fortify

As Sarno puts it, “As e-mail, word processing and data storage continue to move from users' computers to the Web, companies must fortify their servers from a variety of potential disasters -- natural and man-made -- to help ensure that the data and the applications are accessible at all times.” He quotes Google’s SEC filing:

"(Google’s) systems are vulnerable to damage or interruption from earthquakes, terrorist attacks, floods, fires, power loss, telecommunications failures, computer viruses, computer denial of service attacks" as well as sabotage and vandalism...

The good news is that today, ZeroNines' Always Available™ CloudNines™ technology can fortify servers from damage or interruption from earthquakes, terrorist attacks, floods, fires, power loss, telecommunications failures, computer denial of service attacks, as well as sabotage and vandalism. We leave the viruses to others to deal with, but we can add most types of routine maintenance, unplanned maintenance, data migrations, equipment upgrades, software upgrades, and a number of other potential causes of downtime.

Forget Failover

The IT world fatalistically believes that downtime is inevitable, and is something to be lived with and minimized if you’re fortunate. This view predominates because until now the only disaster recovery solution available has been the flawed failover paradigm, which everyone in IT knows can be a disaster unto itself. During a crisis or failover event, cutover can cause additional problems, downtime, and cascading application failures as computing switches from primary to backup systems.

But the IT world has it wrong. Disasters will happen and must be dealt with, but the downtime they cause can be prevented.

Always Available™ Means Virtually 100% Uptime

ZeroNines’ Always Available™ solution eliminates failover and backups, instead providing synchronous identical processing on multiple cloud nodes geographically separated by thousands of miles. If a storm wipes out your East Coast cloud, CloudNines enables processing to continue on clouds in other parts of the country and around the world. If you need to upgrade server software, you can isolate one cloud node, do your upgrade, and bring it back online once it is stable. Our technology has journaling and updating features to assure that all transactions are completed and that any cloud node that goes offline is brought up to the most accurate logical state once it comes back online.

CloudNines can push application availability beyond the industry-accepted standard of 99.999% (five nines) to virtually 100%. In our ongoing test case, the ZeroNines MyFailSafe environment has never experienced any downtime at all, for any reason. It went live in July 2004, and had individual network nodes knocked offline a number of times due to hurricanes, power outages, server migrations, and other causes. All applications experienced full 100% availability throughout.

Will ZeroNines eventually be recognized as a vital cloud-enabling technology? That remains to be seen but you can bet that is how we see ourselves. If you want to find out how we can make the cloud a viable option for you, let me know.
