1 Executive Summary

Cloud computing is quickly becoming the platform of choice for users and businesses that

want to reduce operating expenses and be able to scale resources rapidly. There are several

other advantages of moving resources to the cloud such as eased automation, flexibility,

mobility, resiliency, and redundancy.

Even though cloud computing is in the early stages, there are different types of cloud

solutions available to businesses today. Private clouds allow businesses to take advantage of

cloud technologies while remaining on a private network. Public clouds allow businesses to

make resources available to external consumers. In addition to that, using a public cloud

reduces the need to evaluate new hardware, deploy the infrastructure or support it. Hybrid

clouds allow the best of both public and private cloud computing models because it allows

reallocation of traffic to public cloud providers based on a spike in traffic.

Cloud computing provides several different services such as Infrastructure as a Service

(Iaas), Platform as a Service (PaaS) and Software as a Service (SaaS). These standards are

defined by NIST (National Institute for Standards and Technology)

and are discussed in detail

within this paper.

Red Hat Cloud Foundations (RHCF) provide the software infrastructure required to build

public, private and hybrid clouds by utilizing open source technologies that are available

today. Some of the key technologies that RHCF utilizes are Red Hat Enterprise Linux (RHEL),

Red Hat Enterprise Virtualization (RHEV) which serves as the foundation of the virtualized

hosts and Messaging, Realtime and Grid (MRG) which provides a framework for distributing

workloads in a high speed, efficient manner. RHCF also utilizes Red Hat Network Satellite

technologies to manage parts of the infrastructure and components of the JBoss suite as a

middleware platform used for scaling applications. RHCF utilizes many other technologies

that are going to be discussed in greater detail in the following sections.

The next evolution of cloud technologies is Red Hat CloudForms. Red Hat CloudForms

provides advanced features such as Self Service, Resource Abstraction and pooling, creation

and management of images, and complete Application and Life Cycle Management. These

capabilities are additive to current products that provide full cloud functionality and

capabilities.

This paper takes all the required Red Hat Cloud Foundation technologies and presents best

practices for tying them together. The entire cloud stack is covered from the Red Hat

Enterprise Linux operating system to the applications that scale on top of it.
