Herndon, Virginia - (The Hosting News) - September 24, 2007 - Virtualization software company, SWsoft, will merge with Sphera Corporation's automation software business unit, through its acquisition of the software-as-a-service (SaaS) solutions firm. Financial details of the transaction were not disclosed.

Sphera provides automation, provisioning, virtualization and management software for hosting companies, telecoms and enterprises. It has been a pioneer in developing SaaS and hosting solutions since its founding in 1999 and has partnerships with IBM, Microsoft and Mitsui. Leading telecom providers such as AT and T, Japan Telecom and Telecom Italia utilize Sphera's platform to serve 150,000 businesses and more than one million end users with hosted applications.

Industry analyst IDC predicts that SaaS software revenues will reach $10.7 billion by 2009. Serguei Beloussov, CEO of SWsoft offered, ''We're building a broader solution set and customer base as a technology provider -- using a standards-based approach -- to enable the delivery of SaaS by application developers and service providers. Through our three recent acquisitions, we estimate that we will be able to reach nearly 1.5 million additional business customers through our ISV and service provider partners.''

Under a SaaS model, software is accessed on demand and is made available to users over a network, typically the Internet, instead of as a ''boxed'' product. The software programs are hosted by a service provider, with benefits that include automatic updates and easier administration, global accessibility, along with compatibility since all users have the same software -- not different versions.

John Zanni, Managing Director of Worldwide Hosting in the communications sector at Microsoft Corp. commented, ''SWsoft and Sphera are two very important Microsoft industry partners. The combined company broadens not only the solution set, but also the customers and markets that Microsoft can reach.''

Melanie Posey, Research Director at IDC noted, ''This move is a good fit and positions SWsoft and Sphera to lead in the delivery of SaaS technology used by software developers and service providers that, in turn, can deliver software-as-a-service to their business customers.''

Michael Gold, the former CEO of Sphera, who will become General Manager at SWsoft's SaaS company offered, ''With the full resources of SWsoft behind Sphera's groundbreaking work and success in SaaS deployments, we will be able to expand more rapidly and on a greater scale.''

Using Sphera's technology, service providers and their channel partners manage a portfolio of hosted SaaS applications that are bundled and sold to businesses. Also, Sphera helps ISVs transform traditional software programs to SaaS offerings with no additional application development. With some 50 employees, Sphera is headquartered in Denver with global offices in Tel-Aviv, Israel and Tokyo, Japan.

SWsoft is a virtualization and automation software firm with solutions designed to assist consumers, businesses, and service providers optimize technology use. The company's software powers more than 130,000 servers and 600,000 desktops worldwide. The SWsoft product line includes Virtuozzo - the leading operating system virtualization solution, Parallels - the leading desktop virtualization product, and Plesk - the leading server control panel. Founded in 1999, the company has offices throughout North America, Europe, and Asia.
