WAN Optimization: A Must-Have for Serious Data

by Laura Knight

How important is WAN optimization for cloud services? As a recent TechTarget article demonstrates, it’s pretty much indispensable.

Regional Massachusetts financial institution Eagle Bank recently ran headfirst into the wall of bandwidth limitations. The bank moved its backup array to a disaster recovery site just 10 miles down the road – and to its dismay, discovered that replication would now take 10 days. Its recovery point objective was 8 hours. Because they didn’t have a WAN optimized solution, this was a problem.

Obviously, going dark for days on end wasn’t an option (and least not if there were going to still be a bank afterward), but beefing up the existing WAN infrastructure would be a significant expense. As an alternative, Eagle Bank implemented WAN optimization technology to get more bang for its buck from the bandwidth it already had. This worked great – as Tech Target reports, replication time dropped to just 5.5 hours. WAN optimization had saved the day.

WAN optimization might not sound sexy, but it’s a must-have for any cloud service dealing with serious data. The bandwidth gains it enables are key to making sure a cloud service can handle high-volume data backup and recovery traffic at sufficient speeds to ensure minimal downtime and maximum reliability and recovery.

WAN Optimization for Online Backup and DR Services

WAN optimization is also a critical component for allowing an online backup & DR service to scale with a business as its needs evolve and its data volumes grow. After all, a business with a backup requirement of a few hundred gigabytes might soon find itself with multiple terabytes of data to protect, especially if it’s growing fast. As the data requirements increase, so does the challenge of fitting it all into the backup window.

The bottom line? Make sure your cloud backup and restore has the secret WAN optimization sauce.
