What’s new in Red Hat Enterprise Linux 7?

Red Hat Enterprise Linux 7 (RHEL7)
Red Hat Enterprise Linux Version 7 (RHEL7) was released in June 2014 after six months of beta testing and more that three years since its previous major point release. Red Hat’s latest version of its flagship platform has made significant improvements in reliability, performance, and scalability. The new features offer system administrators, developers, and architects the tools they need to innovate and manage more effectively. Take a look at the following:
Red Hat Enterprise Linux 7 from Architects is ready to integrate with any other operating system, 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, RHEL7 has functionality to support your project.
Red Hat Enterprise Linux 7 System Administrators has new features to help you do your job more effectively. With unified management tools and systemwide resource management, you’ll have greater insight into the system’s performance and more controls to optimize it. This will allow you to gain better control over it. Container-based isolation and enhanced efficiency tools make it possible to adjust the resource allocation for each application. There are also ongoing improvements in scalability and reliability as well as security.
Red Hat Enterprise Linux 7 for Developers & Devops provides more than an operating system. It also includes a rich application infrastructure that offers built-in mechanisms to optimize performance, security, identity management, and resource allocation. You can also take advantage of controls to manage application resources to ensure that performance is not compromised. RHEL7 contains the most current stable versions of the most popular programming languages, databases, and runtime environments.
This version of Red Hat Enterprise Linux 7 (RHEL7) is geared more towards data centers and enterprises. Here are five of the most notable features in RHEL 7.
1. Integration with Docker Technology Docker technology is a popular and cutting-edge application virtualization technology. Docker allows applications to be isolated from the system, which allows for greater mobility and flexibility. RHEL 7 has been optimized for Docker to allow this new technology to be used. This allows resources to be properly allocated and runtime editions defined.
2. Systemd Replaces Init Systemd was originally created to replace the init program in the days when proprietary Unix was used. It allows for more efficient loading services during the boot process. The systemd process manager is not well-received by Linux pundits and system administrators. Red Hat is excited to add systemd to RHEL 7.
3. XFS is default The default file system in Red Hat has been changed to XFS. RHEL 6 shipped with an option to use the XFS filesystem, but defaulted to ext4. The XFS file system supports file systems up to 500TB in size. There are many other benefits. There is no easy way to migrate ext4 and btrfs files to XFS. Other than backing up and restoring.
4. Active Directory Compatibility RHEL7 improves its compatibility to Active Directory (AD). It adds two key features: realmd and cross-realm trusts. Cross-realm trusts are now possible between RHEL7 and AD. This allows users to access resources on the Linux side of the network without needing to sign-on again. Realmd automates the discovery of AD (or any other Red Hat identity services) using DNS information, and the process for joining.
5. PCP Performance Co-Pilot (PCP), a new performance monitoring system, monitors and records system stats and sports APIs. It also provides a toolkit for making this data available to other subsystems like the newly introduced system. RHEL 7 has new performance profiles that emphasize maximum throughput performance. It also includes a new default profile to balance performance against energy savings.
