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.

Open source 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 leading work on 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:

• Deltacloud - Abstracts the differences between clouds

• BoxGrinder - A set of projects to build appliances for a multitude of virtualization fabrics

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

• Condor - Batch system managing millions of machines worldwide

• CoolingTower - Simple application-centric tool for deploying applications in the cloud

• Hail - Umbrella cloud computing project for cloud services

• Infinispan - Extremely scalable, highly available data grid platform

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

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

devices

• Thincrust - Tools to build appliances for the cloud

3.3.1 Deltacloud

The goal of Deltacloud is simple: making many clouds function as one. Deltacloud strives to

bridge the differences between diverse silos of infrastructure, allowing them to be managed

as one. Organizations today may have different clouds built on, for example, RHEV-M or

VMware vCloud. The Deltacloud project is designed to make them manageable as one cloud,

one pool of resources. Organizations may wish to use internal cloud capacity, as well as

public clouds like Amazon's EC2, and perhaps capacity from other IaaS providers.
