Internap Network Services Corp., an Atlanta-based IT infrastructure services provider, said it will acquire iWeb, a Canadian hosting and cloud provider, in a $145 million deal.

Montreal-based iWeb, which has 200 employees, serves 10,000 customers in more than 100 countries.

Internap said the deal builds on its acquisition of cloud provider Voxel in December 2011.

“IWeb fits perfectly into our strategy to deliver a comprehensive portfolio that can serve the needs of our customers at every stage of their business lifecycle, from an initial start-up wanting a single dedicated server to a scale-out Internet app provider or global enterprise requiring a hybrid solution across multiple data centers around the world,” Internap President and Chief Executive Officer Eric Cooney said in announcing the acquisition.
