NTT expands data center, cloud to US with acquisition

NTT has also agreed to acquire all of Virtela for about $525 million in cash in order to get its hands on the Denver-based company's infrastructure and services. The company offers services to improve the response times of hosted applications. It also has a large portfolio of cloud-based security services as well as network virtualization expertise.

The deal expands NTT's global network services coverage from 160 to more than 190 countries or regions, and combined services will arrive next year.
