8 Great Cloud Storage Services
eMeter is a 200-employee unit of Siemens that produces software for electric, natural gas and water utility management systems. Its EnergyIP platform is intended to permit a utility to mix information from smart meters with information at the grid’s operation to higher serve customers.
With portion of its development in India and part in Redwood City, Calif., eMeter turned to Bluelock cloud data centers in Indianapolis and Las Vegas to store the recovery copies of its systems. Under a Bluelock service launched in early May, virtualized copies of first-tier production systems were created and stored in a Bluelock data center, with a continuing data feed from production systems associated with the identical data center.
Within the event of a disaster, the sleeping virtual machines can be woken up and information fed into them reflecting the last known point of knowledge integrity.
That became necessary, recalled Pat O’Day, CTO of Bluelock, when an eMeter customer in India botched its try to install a needed energy management system last month. eMeter senior systems administrator Bryan Bond got a decision in the course of the night inquiring for assist in getting it back up. He did so in three hours by activating the backup copy in a Bluelock cloud center and resurrecting its data feed, a role that might have taken four to 5 business days under the prior recovery system, O’Day recounted.
“numerous midsized companies up to now did not have access to this sort of recovery system, as a result of cost,” said O’Day in an interview. Bluelock’s Recovery-as-a-Service (RaaS) will depend on keeping an up-to-date copy of complete system files in the cloud, and replicating data at the hypervisor level.
The Bluelock recovery system places an agent on the primary system that watches the I/O stream to storage. When a change has been made in the configuration or any files of the primary system, that information is captured and sent to the recovery system. Likewise, as data is worked on by the system, a duplicate copy in the cloud is kept in sync. If the customer wants a guarantee of complete data recovery, the customer must invest in a high-speed network link that can transmit large amounts of data as a shutdown of a primary system approaches.
Usually customers settle for some last-second loss of data in exchange for the ability to restore data integrity as much as the approximate point of failure. Attempting to maintain real-time failover to a backup system at a distant site incurs steep costs. Bluelock RaaS is meant to be an alternative to that.
O’Day said companies used to come to Bluelock with a pilot workload and secondary production systems to run as get-acquainted exercises. Now new customers are getting acquainted by using the cloud as a recovery mechanism for a running production system. As they learn how it can function in this way, they gain confidence within their ability to use infrastructure-as-a-service for other purposes.
“At least half of our new business is coming to us” through the recently launched Recovery-as-a-Service, he said.
“Cloud services are not an experimental option. They’re seen as an alternative to purchasing your own assets,” he said.
Such a claim could be expected from a cloud services provider. Bluelock remains a small one compared to Amazon Web Services, Google or Microsoft. It closed its data center space in Salt Lake City after expanding space in Las Vegas. That leaves customers that are, let’s say, in the path of Hurricane Sandy on the East Coast with basically one place to link to — Las Vegas. It’s not unheard of for a winter storm that shuts down the East Coast to also severely impact Indianapolis, Bluelock’s headquarters and initial data center location.
Las Vegas is a long ways from Chapel Hill, N.C., Washington, D.C., or Boston, conceded O’Day. But customers can are better off having a greater latency in their backup system than having no backup system at all. In addition, they can engineer the data feed with as much communications line capacity as they care to purchase. “They can be as real time as they care to afford,” he noted.
Journaling events on the recovery site allows data to be recovered for a period of up to two days prior to the occurrence of a failure, ensuring a deep enough record to revive data integrity at a recovery point before the failure, O’Day noted.
In addition to hurricanes, there are other reasons to keep a backup system readily available at a far off site. Sometimes it’s an intruder who’s gotten into the system and IT must turn to a clean copy and recovery point where it knows the information was unaffected. Other times it isn’t a natural disaster but a manmade one — a failed try to upgrade a production system that results in the desire for a rollback and reactivation of a legitimate copy.
