RedHat breathed new life to the Red Hat Enterprise Linux
Operating system there by giving birth to enthralling RHEL 7 which
transcends the boundaries of an OS with vessels for containerized
applications. Hence RHEL 7 is no longer just a simple OS but an
abstracted component in the larger RedHat ecosystem. For a flawless
understanding of the significant features of RHEL 7 it would be better
to go through the following 10 Red commandments
• RHEL 7 offers an increased support for hosting Virtualized Windows
server Edition than RHEL 6 and with an updated SAMBA 4, RHEL 7 is almost
a member of Microsoft network
• RHEL 7 has the responsibility of an OS subscription model which is
tuned for a stable business deployment. It prevents instance of being
out of support or highly re configured.
• RHEL 7 is a huge pile of code, running 4.3GB in the DVD ISO
• Red Hat’s support of Linux containers (LXC) which helps the users to
deploy Type-2, OS-based virtualization, rather than Type-1 bare metal
hypervisors. LXC allows the container to be both lightweight and highly
isolating.
• RHEL 7 support project atomic which allows moving a workload from one
OS to another as transparent to workload. This becomes the job of
relationship stack components especially open stack. Thus once an app
tests successfully as an isolatable container instance, it can become a
package, much as software appliances are found and deployed.
• RHEL 7 now uses the xfs file system instead of ext4 by default. This
means that RHEL can handle extremely large file systems, as much as 8
exbabyte.
• RHEL 7 offers a tighter link to Active Directory. Hence those looking
for a cross platform compatibility with Windows active directory receive
new Kerberos support that allow them to do this.
• RHEL 7 is easier to install and deploy: The RHEL 7 kernel update to
3.20 is similar to Canonical’s implementation. In terms of distribution
RHEL7 slightly easier to deploy on bare metal, and about the same on
VMware, Hyper-V, and Citrix XenServer.
• RHEL 7 is built for business environment at the installation time one
should choose from several type of base environment like minimal,
infrastructure server, file and print server, basic web server,
virtualization host etc.
• RHEL 7 in peppy in terms of performance Gnome is very dynamic. And
optimization of varying roles could be well documented. RedHat can
increase output through a new feature of network port teaming.
