Red Hat (NYSE:RHT) has released the new Linux 5.1 with integrated virtualization, a new platform for customers and software developers that offers a broad deployment ecosystem, covering standalone and virtualized systems, appliances and Web-scale cloud computing environments.

The company has also introduced the beta launch of Red Hat Enterprise Linux on Amazon Elastic Compute Cloud (Amazon EC2), a Web service that provides resizable compute capacity in the cloud. EC2 makes all the capabilities of Enterprise Linux available to customers on Amazon's network infrastructure and data centers. Customers pay only for the capacity they use, and can increase or decrease capacity within minutes.

Enterprise Linux allows customers to deploy a single platform, virtual or physical, throughout their organization, which is more efficient and cost-effective than proprietary solutions. Fully integrated virtualization, included at no additional cost, amplifies these benefits. Enterprise Linux 5.1 provides enhanced support for virtualization of Microsoft Windows guests, improving the performance of Windows XP, Windows Server 2000, 2003 and Windows 2008 beta.

Red Hat Enterprise Linux is the first commercially supported operating system available on Amazon EC2.
