OnApp announced today that it has closed a Series B round of funding, bringing total funding to more than $20 million. OnApp currently powers public cloud services for more than 500 service providers across 39 countries, making it the most widely deployed cloud management platform globally. The company is now poised to further accelerate the rapid growth of this ecosystem.

Existing investor, LDC, the leading UK private equity house focused on growth businesses, led the round. The funding will be used to help OnApp roll out a new line of products and services in 2013, as well as expand into new global markets.

“In 2010, we set out to build a turnkey platform to make it easy for service providers to create profitable cloud services,” said OnApp CEO, Ditlev Bredahl. “Our customers now run some of the fastest growing cloud services out there, with an average annual growth rate of over 80%. We’ve also seen a new breed of Virtual Service Providers emerge, who are creating a wide range of cloud-based businesses on top of the OnApp Marketplace.

“This round of funding gives us a solid financial base from which we will continue creating products that make OnApp-powered service providers the most successful in their markets.”

Since the launch of OnApp’s flagship product, OnApp Cloud, OnApp has made a name for itself as a disruptive force in the industry with the launch of OnApp CDN, the OnApp Marketplace and OnApp Storage.

OnApp CDN, a content delivery network designed to optimize website performance, has grown to more than 130 points of presence in 39 countries in the space of a year by federating the spare cloud capacity of existing OnApp customers. This makes it the third largest CDN globally by number of points of presence, larger than the Amazon Web Services and Microsoft Azure CDNs combined. It is unique in allowing service providers to monetize their spare infrastructure through the OnApp Marketplace.

OnApp Storage does away with the need to purchase expensive, power- and-space-hungry Storage Area Networks (SANs) by aggregating the capacity of commodity physical disks, on existing datacenter servers, into a virtual SAN with enterprise-class resilience and performance. OnApp Storage’s unique VMAware technology ensures that a copy of data sits on the same server as the application that needs it – removing performance bottlenecks associated with centralized storage.

The combination of these products with OnApp’s cloud deployment expertise means that service providers can get to market fast with a range of profitable cloud–based services that end customers love.

Headquartered in London, OnApp generates 40 percent of its revenue from the U.S. market, and is also seeing strong growth in Asia Pacific and Latin American markets. OnApp customers include major international hosting brands such as PEER1, GMO and UK2, as well as fast-growing Cloud Service Providers such as Dediserve and eApps.
