Hosted will provide Belk with managed and dedicated hardware, server virtualization, firewall, load balancing and other services.

“This is an exciting time in the history of Belk,” said Roddy Kerr, Belk’s executive vice president and chief information officer. “Finding the right hosting partner was an important priority for us when deciding to launch our e-commerce site.

In April, privately held Hosted was acquired by ABRY Partners, a Boston firm, in a deal worth $140 million.

Hosted operates two data centers in the Triangle, two in Charlotte and another in suburban Boston.
