and cost-effective cloud computing. Red Hat's cloud vision is unlike that of any other IT

vendor. Red Hat recognizes that IT infrastructure is composed of pieces from many different

hardware and software vendors. Red Hat enables the use and management of these diverse

assets as one cloud. Enabling cloud to be an evolution, not a revolution. Red Hat's vision

spans the entire range of cloud models:

• Building an internal Infrastructure as a Service (IaaS) cloud, or seamlessly using a

third-party's cloud

• Creating new Linux, LAMP, or Java applications online, as a Platform as a Service

(PaaS)

• Providing the easiest path to migrating applications to attractive Software as a Service

(SaaS) models

Red Hat's open source approach to cloud computing protects and manages existing and

diverse investments as one cloud -- whether Red Hat Enterprise Linux or Microsoft Windows,

Red Hat Enterprise Virtualization, VMware or Microsoft Hyper-V, Amazon EC2 or another

vendor's IaaS, .Net or Java, JBoss or WebSphere, x86 or mainframe.

Red Hat's approach to open source cloud computing also prevents vendor specific lock-in.

For example, when the third-party cloud providers are abstracted, the consumer can choose

where to run the virtual machines or where to scale the applications based on cost and

reliability.

3.3 Redefining the Cloud

Cloud computing is the first major market wave where open source technologies are built-in

from the beginning, powering the vast majority of early clouds. Products that make up Red

Hat's cloud infrastructure include:

• Red Hat Enterprise Virtualization

• Red Hat Enterprise Linux

• Red Hat Network Satellite

• Red Hat Enterprise MRG Grid

• JBoss Enterprise Middleware

In addition, Red Hat is leveraging open source work and investing in several open source

projects related to cloud computing. As these projects mature, after they undergo rigorous

testing, tuning, and hardening, the ideas from many of these projects may be incorporated

into future versions of the Red Hat cloud infrastructure. These projects include:

• Cobbler - Installation server for rapid set up of network installation environment

• Condor - Batch system managing millions of machines worldwide

• Hail - Umbrella cloud computing project for cloud services

• Libvirt - Common, generic, and scalable layer to securely manage domains on a node

• Spice - Open remote computing solutions for interaction with virtualized desktop
