Hosted Solutions, a provider of data hosting and other managed information technology services, has completed a series of upgrades to its new data center in the Boston area.

Hosted acquired a data center company in Charlestown, Mass. last year. It has made nearly $1 million in infrastructure improvements in the center.

Over the next 12 months, Hosted plans to make another $1.5 million in upgrades. Among the planned changes are a redesigned network operations center and the addition of a storage area network.
