IntroductIon

Red Hat’s latest release of its agship platform delivers dramatic improvements in reliability,

performance, and scalability. A wealth of new features provides the architect, system administrator,

and developer with the resources necessary to innovate and manage more efciently.

Architects: Red Hat

Enterprise Linux

7 beta is ready for whatever infrastructure choices you

make, efciently integrating with other operating environment, authentication, and management

systems. Whether your primary goal is to build network-intensive applications, massively scalable

data repositories, or a build-once-deploy-often solution that performs well in physical, virtual, and

cloud environments, Red Hat Enterprise Linux 7 beta has functionality to support your project.

System administrators: Red Hat Enterprise Linux 7 beta has new features that help you do

your job better. You’ll have better insights into what the system is doing and more controls to

optimize it, with unied management tools and system-wide resource management that reduce

the administrative burden. Container-based isolation and enhanced performance tools allow you

to see and adjust resource allocation to each application. And, of course, there are continued

improvements to scalability, reliability, and security.

Developers and dev-ops: Red Hat Enterprise Linux 7 beta has more than just operating system

functionality; it provides a rich application infrastructure with built-in mechanisms for security,

identity management, resource allocation, and performance optimization. In addition to well-tuned

default behaviors, you can take advantage of controls for application resources so you don’t leave

performance up to chance. Red Hat Enterprise Linux 7 beta includes the latest stable versions of

the most in-demand programming languages, databases, and runtime environments.

Whichever role (or roles) apply to you, the Red Hat Enterprise Linux team hopes that you will nd

features and enhancements in Red Hat Enterprise Linux 7 beta that you want to test and try out,

and then share your feedback.

LInux contaIners

Linux containers provide a method of isolating a process and simulating its environment inside

a single host. It provides application sandboxing technology to run applications in a secure

container environment, isolated from other applications running in the same host operating

system environment. Linux containers are useful when multiple copies of an application or

workload need to be run in isolation, but share environments and resources.
