Migrating to cloud computing? Don’t forget DNS

The cloud computing model offers the promise of reduced IT operational costs, which may prove appealing in these recessionary times. But before you mothball your data center and start using servers distributed across the ‘Net, you need to rethink your DNS infrastructure, experts say.

Dynamic Network Services Inc. — dubbed Dyn Inc. — a New Hampshire provider of enterprise and consumer DNS services, is expanding its line of outsourced DNS services to address the many issues that crop up when companies migrate to cloud computing.

Dyn Inc. is adding traffic management features to its Dynect platform for enterprise customers. Starting in January, the platform, used by several hundred companies, will be sold with add-on global load-balancing that allows customers to route traffic geographically to the closest available server to improve the latency of Web applications.

“As cloud computing takes off, I think traffic management is going to be a very big deal for people running dynamic Web apps, especially those using [content delivery networks] like Akamai,” says Jeremy Hitchcock, CEO and CFO of Dyn Inc. “CDNs are wonderful for handling small and large file downloads and streaming media. But if you have a database-backed application, it seems hard to make that work with a CDN. So, what a lot of customers prefer to do is grab a Rackspace server in Dallas and a Verio box in Detroit . . . but they have no way to make sure that people get to the application servers that are geographically close to them. . . . They end up with bad, unoptimized Internet routing.”
