10 commandments of RHEL 7

And that 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.

The journey is the destination - Congrats Pawel

Mr Pawel Jerry Fiuto,a Polish National living in the UK had been with the ipsr family from July 22 - September 25,2014 and has successfully completed four modules of the RHCA track with us - RH442 : RedHat Enterprise System monitoring and performance Tuning , RH413:RedHat Server Hardening , CL210  :  Red Hat Open Stack Administration , RH318 : Red Hat Enterprise Virtualization. He had previously passed EX436 - Red Hat Enterprise Clustering.

Pawel Jerry is a Bachelor's Degree holder in Computer Science and is currently working as System Administrator .His passion for travelling is evident from the fact that he scaled the glorious mountains of China a week before coming to India and his frost bitten skin was an example of how he was pushed to the extremes by the explorer within him. IPSR family admires his passion to travel all over the world and look forward to see him again, as this was his second time in India.
