FreeNAS is well suited for most storage serving scenarios, whether it be for an office file server, backup destinations, data replication across the internet, or as backend storage for virtual machines. It can serve various types of clients via a plethora of standard protocols and can easily integrate with existing infrastructure using LDAP authentication and so on. It's pretty simple to use (it helps to have at least a basic understanding of the underlying technologies) and almost maintenance-free. One scenario that springs to mind that it may not be appropriate for (yet) is as S3 storage. However, S3 functionality was added in a recent release and may have improved greatly since then. I'm sure it will eventually work very well for this.
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.
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.
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.
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.
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.
FreeNAS effectively uses all resources really well and it is highly recommended for in premises NAS. It has unlimited ROI as it is really free and open-source. The only payment we need to pay is when we need any support from those guys. FreeNAS helps us to effectively do our work with the legacy systems as it manages all the components really well. FreeNAS although rebranded to TrueNAS will still be there until our legacy systems run.
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.
