Red Hat Enterprise Linux

In this demo, Scott Collier shows how to use Docker containers (the contents of an image and its features) to cat out contents of /etc/host, launch a web server, and bindmounting log files to see activity on host machines.

How do you modernize your datacenter while maintaining the integrity of your current system? Red Hat Enterprise Linux offers stability and reliability on a single, open platform, so you can focus on the projects that add value to your business.

Senior Software Maintenance Engineer Neil Horman from Red Hat demonstrates cgroups, a generic mechanism the kernel provides for grouping of processes and applying controls to those groups. The grouping is done via a virtual filesystem called 'cgroup.' Within this filesytem, each directory defines a new group. Tunables within a cgroup are provided by what the kernel calls 'controllers.' Each controller is able to expose one or more tunable or control. When mounting the cgroups filesystem, it is possible to mount the filesystem several times, with each mount point having a different set of (non-overlapping) controllers. The key idea is that this allows the administrator to construct differing group hierarchies for different sets of controllers/tunables, which offers new ways to control and manage cloud resources.

Mission-critical RAS capabilities on Intel hardware. Applications that run best on Red Hat Enterprise Linux. Scalability, flexibility, reliability. All these factors contribute to the highest levels of performance made possible with Red Hat Enterprise Linux 6. Hear our partners--IBM, HP, Dell, BMC, and more--explain why.

In this two-hour session, Douglas Shakshober (Shak) and Larry Woodman will explore the system performance analysis and tuning necessary to maximize the performance of systems running Red Hat Enterprise Linux 5 and 6. They will focus on large systems that run the most common applications such as database servers, Internet servers, and various financial applications on a variety of the common hardware platforms.

Secure-24, a Red Hat Certified Cloud Provider, partners with Red Hat to ensure stability, scalability and security with Red Hat Enterprise Linux, Red Hat JBoss Middleware, and Red Hat Satellite.

Join Red Hat on May 15, 2012 to celebrate 10 years of Red Hat Enterprise Linux

Companies around the world are turning to the Cisco Unified Computing System (Cisco UCS) and Red Hat Enterprise Linux OpenStack Platform to simplify the process of building cloud infrastructure. Learn how these two leading companies are paving way to an open cloud. Learn more about Red Hat Enterprise Linux OpenStack Platform: www.redhat.com/openstack

Adobe Systems, a long-time user of Red Hat® Enterprise Linux®, wanted to offer its enterprise customers easy access to sandbox resources to evaluate and prototype solutions using Adobe products. Turning to the cloud, Adobe used Red Hat Enterprise Linux and Amazon Web Services (AWS) to not only deliver a sandbox solution, but also to offer customers a Software- as-a-Service (SaaS) option for deploying Adobe-based solutions. Today, Adobe is using the Red Hat platform and Amazon Web Services to help customers simplify deployment, lower cost of ownership, and accelerate time to value.

In this session from the 2012 Red Hat Summit, Andrew Cathrow, product manager, and Chuck Dubuque, product marketing manager for Red Hat Enterprise Virtualization. They discuss Red Hat virtualization, including Red Hat Enterprise Virtualization 3, and the past, present, and future of virtualization technology. Dubuque discusses the current environment, including virtualization competitor VMware, and the opportunity that a second source for virtualization--a open standards source--offers. He then offers details about Red Hat Enterprise Virtualization, including information about management features, hypervisor technology, specVIRT success, and opportunities for cost savings. Cathow then joins in to talk about development of Red Hat Enterprise Virtualization 3 and 3.1, and the growth of the communities surrounding it, including Fedora and oVirt. Cathow highlights features and changes in Red Hat Enteprise Virtualization, including: - OpenJDK requirement for proprietary Oracle JRE is eliminated. - Support for Jasper 4.7 and two new directory servers - Scalability to 160 Virtual CPUs per VM and 2T virtual RAM per VM - enhanced physical to virtual migration (P2V) - Live snapshots - Shared disks - SDK availability - new top-level manager for managing disks - direct LUN access Cathow details many other system and version features, including a overview of key technologies for future versions of Red Hat Enterprise Virtualization and Red Hat Enterprise Linux. He also intermittantly takes questions from the audience. Watch more 2012 Red Hat Summit and JBoss World videos from Red Hat: http://www.youtube.com/playlist?list=PL995CD1141C3330D5&feature=plcp

Ever wonder how great features make it from the community into enterprise-ready technology like Red Hat(R) Enterprise Linu(R)? Fedora Project Leader Paul Friends explains how projects started upstream gain in popularity and maturity, are hardened and tested, and eventually make their way to enterprise solutions.

In this two-part session, Mark Heslin will review the various concepts, components, and configuration options available for integrating the mission-critical readiness of Red Hat Enterprise Linux 6 into Active Directory domain environments. Emphasis will be placed on understanding the pros and cons of each approach, best practices, and guidelines for selecting the best configuration.

Using content from our Red Hat® System Administration II (RH134) course, this Taste of Red Hat Training video will show you how to manage SELinux modes on your system. In the complete, 4-day course, Red Hat System Administration II focuses on the key tasks needed to become a full time Linux® administrator. It is part II of the core system administration tasks needed for Red Hat Enterprise Linux 7 and is the follow-on to Red Hat System Administration I (RH124). This course goes deeper into enterprise Linux administration including file systems and partitioning, logical volumes, SELinux, firewalling, and troubleshooting. Attending both Red Hat System Administration I and Red Hat System Administration II can help you in your preparation for the Red Hat Certified System Administrator Exam (EX200).

IT professionals around the world are getting trained and certified by Red Hat on Red Hat Enterprise Linux OpenStack Platform. We met with a few of the Red Hat Certified Professionals to see how they are leveraging the knowledge and skills from the rigorous, hands-on training and exam. An IT professional who has earned the Red Hat Certified System Administrator in Red Hat OpenStack has demonstrated the skills, knowledge, and abilities needed to create, configure, and manage private clouds using Red Hat Enterprise Linux® OpenStack® Platform.

Red Hat Enterprise Linux transformed enterprise IT, and dramatically changed the software industry forever. By combining the open source development model with a customer-centric subscription based business model, Red Hat gave enterprise customers a way to leverage the value of open source in a way that made sense for them, and that spurred the adoption of Linux across the enterprise. But it wasn't easy. There were doubts and obstacles to overcome, customers and partners to convince, and millions of developers to collaborate with. But with commitment and vision, it all just worked.

In this session, Red Hat's Thomas Cameron and Lon Hohberger will expand upon their 2011 Red Hat Summit presentation, "Clustering Applications with Red Hat Enterprise Linux." Thomas and Lon will discuss the theory and best practice of clustering applications with technologies available in Red Hat Enterprise Linux 6.
