Red Hat Enterprise Linux (RHEL) vs. Red Hat OpenStack Platform

Red Hat Enterprise Linux (RHEL) is best suited for its stability, fast reboot time, and minimal resource requirements which reduce overall cost. The patch time for Red Hat Enterprise Linux (RHEL) is also extremely fast which benefits application up time. For environments or applications that require many changes, for a Red Hat Enterprise Linux (RHEL) support person that is not well trained and experienced in Red Hat Enterprise Linux (RHEL), this can be challenging.

Best suited for - any organization where you have people who already have expertise on OpenStack, Linux & IP networking. Otherwise, the maintenance & operations will be difficult. When the number of deployed VMs reaches its capacity, it becomes very difficult to manage Red Hat OpenStack because there are no in-built fault management & performance management tools available within Red Hat OpenStack. Not suited for - Organizations where people have a culture of working on automated GUI-based tools. Here VMware wins over Red Hat OpenStack. Also where you have mission-critical applications where downtime cannot be tolerated.

• Virtualization, like the operating system level task. I see this product is very good and it blends very well with the middleware components like all the JBoss and other things. And other than that, either you install it or a virtual machine or physical servers, it works seamlessly anywhere. And if you want to go further, like Red Hat OpenShift or those things also work very nice with it.

• Scaling of application components (VMs).
• Managing the networking between virtual machines.
• Management of VNFs & the underlying infrastructure.
• Availability & uptime of VMs because of features like VM migration & evacuation.

• In the LEAP process. The upgrading process, which I'm hearing, like I said it before, prior that I was on rail seven, eight, and nine. Trying to get all of that to rail nine and stay current. The LEAP process from seven to eight is a little bit less than desired. I've talked to some people that from once you get on eight from eight to nine to nine to 10 is a breeze. So I'm looking forward to that.

• User management really needs improvement - when compared to AWS or GCP.
• Security of the overall platform needs to be improved.
• The whole architecture needs to be modular which is not. Ex - Upgrading any particular component (nova, neutron, cinder) should be possible without upgrading the whole Red Hat OpenStack version.
• The creation of HEAT templates for complex applications is still a challenge & has a dependency on external tools.
• Stack creation still requires parameters modification at controllers & compute because of the complex nova-scheduler algorithm.

We find RHEL to be a superior OS with stable operations and long life. It is also easier to use and fix then most other OS's.

The Red Hat Enterprise Linux (RHEL) distro is the simplest enterprise version of Red Hat that is enterprise supported and when you deploy as many VMs as we do, it is vital to have that enterprise support. On top of the enterprise support, having access to a commercially supported backbone for updates and upgrades is a huge plus.

Product support and regular patches.

As with any OS enhanced testing will need to be done prior to application integration.

Red Hat support has really come a long way in the last 10 years, The general support is great, and the specialized product support teams are extremely knowledgeable about their specific products. Response time is good and you never need to escalate.

Don't be afraid of it, its easy to install and configure for the tasks needed.

So we in our company have used Ubuntu as well. Sometimes we have to use that because a certain application installer requires that we use that operating system, but we really don't prefer it just because it doesn't come with the same Add-on features that make Red Hat Enterprise Linux (RHEL) really great, like Red Hat Insights or Red Hat satellite, things like that. They come package with it. So that would be the main one. I've also used things like FreeBSD, but I think that's just too old at this point to care.

Only because of low cost & zero licensing of Red Hat OpenStack

Operational ease of use backed by support

• RHEL provides a good base OS and additional tool sets for various deployments.
• We are able to use Satellite to manage hundreds of OS's behind our corporate firewall. No other OS provides the level that RHEL does.
• It is a known good quantity. Their support for the OS is amazing.

• Saved CAPEX for sure (I can't quote a figure).
• Saved Opex also - because a large support community is already available.
• Increased complexity of system setup though.
