IBM z/OS vs. Red Hat Enterprise Linux (RHEL)

IBM z/OS, more specifically Omegamon, has access to a lot of relevant information for monitoring but a 90s interface with little or no ease of use and/or maintenance.

Red Hat Enterprise Linux (RHEL) is well suited for cloud environments, fast deployments and to run non-intensive apps/tools (with low memory and low cpu consumption).Red Hat Enterprise Linux (RHEL) might not be suited for really huge databases and intensive CPU processing.

• provides infrastructure metrics
• provides historical transaction behavior
• provides metrics on vital components for z/OS

• 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.

Incentivized

• end-to-end requests
• correlated metrics of vital components
• facilities to consume historical transaction data

• 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.

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.

IBM needs to update, modernize and improve the usability of the Omegamon interface

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.

Operational ease of use backed by support

• We need to have Observability on the Mainframe

• 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.
