Per Brian Stevens, CTO of Red Hat Inc, Red Hat has slowed the release cycle for its flagship OS distribution and to lower operational costs. Users costs aren't just the OS cost. It's all the costs of configuration, management and provisioning that far outweigh technology replacements.
Many customers plan to skip RHEL 6.5 and planning on upgrading straight from RHEL 6.4 to 7.
Per RedHat, version 7 garnered its largest beta testing community to-date -- 10,000 RHEL users.
Let's talk about few cool features.
(1) Ksplice - allows administrators to patch the kernel without rebooting servers. This is good for environment which needs 24/7 so scheduling downtime is no longer a need.
(2)Improvement to SELinux - This version includes security and systems management and the ease of use improvements to SELinux
(3) Active Directory interoperability - in RHEL 7 provides RHEL more compatibility with Windows OS. The question used to be Linux or Windows on servers; now Linux and Windows OSes coexist in the data center.Customers will be able to sync Windows domain controllers with RHEL 7 for easier identity management. There are many customer shops uses Windows and Linux on a mix of virtualized and physical servers so this will be a good news.
(4) Red Hat Enterprise Linux Atomic Host - lightweight Linux Container host. RHEL 7 can abstract and isolate applications by deploying them in containers with RHEL Atomic Host. It has strong integration with Docker, which allows applications to be packaged in isolated containers. RHEL 7 containers keep applications from fighting over resources, which version of Java to use or other factors. The application takes as much of the OS as it needs to be able to move around and perform equally on bare metal, virtualized servers and private and public cloud infrastructures.
(5) Additional Interesting thing - Red Hat also flipped the relationship between the CentOS operating system and RHEL this year. Per CTO, CentOS is an OS for big data, for software-defined networking and the end users don't need or want the same kind of support that goes to RHEL users. For the first time now, CentOS development goes ahead of RHEL, rather than trailing the Linux distribution, giving Red Hat more feedback to parlay into new RHEL editions and also increases the cloud-friendly, OpenStack nature of RHEL over time.
