Provides speed and stability; could integrate better into two in ones
Pros and Cons
  • "Stability and speed are the most valuable aspects."
  • "It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."

What is our primary use case?

The primary use case was running an entire government payroll system.

What is most valuable?

Basically stability and speed are the most valuable aspects.

What needs improvement?

Realistically, I found Red Hat to be fairly usable. It was an easy transition from Unix to using Linux and I can't think of any real improvements necessary. If anything, I actually like check config better than system CTL.

For improvements or additional features, it would be nice for it to integrate better into two in ones. If you wanted to go to the desktop computer side of things, it lags behind in that you need to go to something like Fedora to get all the extra bells and whistles.

For how long have I used the solution?

I used the product for 10 years. 

What do I think about the stability of the solution?

The product is stable.

What do I think about the scalability of the solution?

The product scaled very well. The only issues that we have ever really had was in relation to the Oracle database that we're running.

Which solution did I use previously and why did I switch?

I previously used VMware and then Citrix. We made the switch predominantly because we wanted to consolidate licensing. We were using Citrix for our VDI environment and it made sense to shift from VMware to Citrix Zen because the licensing for the actual ZenServer was embedded within our DDI license. It made no sense actually licensing a product that we could actually utilize within our existing license. When you look at the budgetary figures and everything like that, VM ware is not exactly light on the back pocket.

How was the initial setup?

For me, the initial setup was fairly straightforward and because I've been using it for so long I was able to do it myself. In terms of initial deployment, I was able to run up five DMs running Red Hat with Oracle database within a week. 

Which other solutions did I evaluate?

Several options were evaluated. I need to keep up to date on all technical offerings on the market, so it was really about doing a product comparison.

What other advice do I have?

I've always used separate hypervisors so it's difficult for me to give advice. I'm more familiar with the other products so I would rate this product a six out of 10. 

Which deployment model are you using for this solution?

On-premises

A responsive technical support portal is available for quickly solving problems
Pros and Cons
  • "The most valuable feature of this solution is the support portal."
  • "Configuring the network interfaces is much better in Ubuntu and should be improved."

What is our primary use case?

We have been using RHEV in both on-premises and cloud deployments for testing.

In my team, we don't have access to a paid version of Red Hat. Instead, we mostly use CentOS and Ubuntu.

What is most valuable?

The most valuable feature of this solution is the support portal.

What needs improvement?

Configuring the network interfaces is much better in Ubuntu and should be improved. I find this to be the biggest problem. In Ubunto they have the idea of the Netplan, which is much better than the facility in Red Hat.

For how long have I used the solution?

I have been using RHEV for about five months.

What do I think about the stability of the solution?

I have seen some bugs that I fixed on my own.

What do I think about the scalability of the solution?

We have not had to scale this solution because it is not for everyday use. Rather, we use it for testing purposes.

How are customer service and technical support?

Technical support for RHEV is very fast and good. 

Which solution did I use previously and why did I switch?

We use different versions of Linux including CentOS and Ubuntu. CentOS is very comparable to Red Hat because it is almost the same, internally.

How was the initial setup?

In the beginning, the initial setup was quite complex. However, once you get used to it, I would say that the setup is of normal difficulty and not a problem.

What about the implementation team?

I implemented this solution with the assistance of my colleague.

What's my experience with pricing, setup cost, and licensing?

We are using the free version of Red Hat.

What other advice do I have?

RHEV is a good solution and I would rate it a nine out of ten.

Which deployment model are you using for this solution?

On-premises

Good stability and support but is difficult to manage
Pros and Cons
  • "Technically, the main reason why I'm using Red Hat is because of its stability."
  • "I heard that there are big differences between Red Hat eight and seven, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In term of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment."

What is most valuable?

Technically, the main reason why I'm using Red Hat is because of its stability.

What needs improvement?

I heard that there are big differences between Red Hat 8 and 7, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In terms of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment.

For how long have I used the solution?

We've been using this solution for five years.

What do I think about the scalability of the solution?

Scalability is also available. At our company, we have three people managing Red Hat, but about 600 users that use service and hosting of Red Hat.

How are customer service and technical support?

We are in touch with technical support and whenever we have an issue we get good support from the Red Hat team. I am satisfied with their technical support. I am an Open Source fan so this is one of my favorites.

Which solution did I use previously and why did I switch?

We use Windows, of course, and we also use Ubuntu for some other applications. For our core applications, however, we use Red Hat.

What's my experience with pricing, setup cost, and licensing?

I would say the price is acceptable.

What other advice do I have?

If someone asked me, I would strongly recommend using Red Hat. I have spoken to many other Red Hat users. The main issue is the lack of knowledge with most engineers and system admins. They don't know how to use Red Hat. They found that Windows, for example, is easier to manage. I would recommend Red Hat, though, and I would like to do something to raise the awareness of how to use Red Hat. I would strongly recommend they work hard to introduce people to Red Hat and how to manage Red Hat. I know there are courses, workshops, and seminars. Red Hat is doing all of that. The main issue which I think Red Hat has to focus on, however, is that colleges, universities, and most institutions focus on Windows-based solutions. Red Hat has to be there in the education sector, so engineer or system admin graduates will at least have a small knowledge of what Red Hat is.

I would rate Red Hat as seven out of ten. I think it's really hard to get a ten because this is technology and technology is always improving. We'll never stop. Ten means perfect, no improvement required. So I would never rate any tech solution as ten or even nine of ten. I can say, however, that this solution is fine for me.

Which deployment model are you using for this solution?

On-premises

A stable and open-source solution that is good for websites with heavy traffic
Pros and Cons
  • "Red Hat is the most stable system."
  • "The Administration of the Oracle database and the SAP ERP needs improvement."

What is our primary use case?

The primary use case of this solution is for making DNS, website work, DHCP, and other security functions like ID tables and other tools.

What needs improvement?

The Administration of the Oracle database and the SAP ERP needs improvement.

In the next release. I would like to see some additional features to make it easier, such as improvements to the GUI and the maintenance. The maintenance of Red Hat is difficult.

For how long have I used the solution?

I have been using this solution for seventeen years.

What do I think about the stability of the solution?

Red Hat is the most stable system. It's better than other OS solutions.

How was the initial setup?

At first, this solution was deployed on-premises, then I converted it to cloud using VMware tools to make our private cloud on our data center.

What's my experience with pricing, setup cost, and licensing?

This is an open-source solution.

What other advice do I have?

I have always recommended using other platforms versus Windows. I didn't like using any Windows system, Microsoft system or any system with heavy traffic like ERP and Websites.

I recommend Linux.

I would rate this solution a nine out of ten.

Excellent virtualization, good stability, and very good technical support
Pros and Cons
  • "The solution is a great all-round product. The virtualization is especially good."
  • "The solution could use network virtualization."

What is most valuable?

The solution is a great all-round product. The virtualization is especially good. 

What needs improvement?

The GUI interface needs improvement. Not 90%, but 50% or 60% of the work is done from the command line and so on, so the GUI needs work because people are looking for an easier way to manage the environment. Right now, if someone is not very familiar with Red Hat and actually is looking to add Red Hat to the environment, they have to take some training. It needs to be easier to use.

The solution could use network virtualization.

What do I think about the stability of the solution?

The stability is very good. We've had very good feedback on it.

What do I think about the scalability of the solution?

The solution is very scalable.

How are customer service and technical support?

The technical support is very good.

How was the initial setup?

The initial setup can be a bit complex, but it depends on the deployment itself.

What other advice do I have?

We are resellers of Red Hat. We deal with various deployment models, however, we generally deal with on-premises.

I would recommend the solution. Of course, it depends on what an organization is looking for in terms of virtualization.

I'd rate the solution eight out of ten.

Good support and a popular platform for our transition
Pros and Cons
  • "One of the most valuable features of this solution is the popularity of the OS."
  • "It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period."

What is our primary use case?

We have several applications that are pillars of the business, such as ERP and SAP, which were previously in a Windows environment. Our system architects have been working on moving these applications to a Linux environment. This is why we are using this solution.

At the point, all of our work with Red Hat is on-premises.

What is most valuable?

One of the most valuable features of this solution is the popularity of the OS.

The support for this solution is very good. This is the major thing that we are considering with respect to moving platforms.

What needs improvement?

There has to be more effort into closing the security vulnerabilities in this solution because we are facing daily attacks. We would like to have this done faster.

We would like to see live-patching on the systems, without having to require a reboot. It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period.

Improvements can be made to managing this solution, such as enhancements to the GUI.

There should be better integration with third-party tools.

Tools for scanning the hardware, such as the CPU and memory, would make life easier.

For how long have I used the solution?

We have been using this solution for about two years.

What do I think about the stability of the solution?

I have found that the stability is related to the upgrade cycle. I find the cycle a little bit annoying.  If the system is constantly upgrading then it is very painful in terms of the operation.

What do I think about the scalability of the solution?

In terms of scalability, it is handling the load that we have. I don't see any major problems.

Which solution did I use previously and why did I switch?

In addition to using this solution, we are trying to move our CRP solutions to our other platform, SUSE Linux. All of our business applications are moving to Red Hat, although we are getting better support with SUSE.

What other advice do I have?

We are not using the most current release of this solution because from our perspective, it is not mature enough yet.

Another example is that we are moving our Enterprise Content Management (ECM) solution, which is similar to Microsoft SharePoint, to Red Hat.

We have already moved all of our big data systems, as well as all of the digitalization systems to Red Hat. Our Splunk is also on Red Hat. 

I would rate this solution a nine out of ten.

RHEV continues to evolve and delivers functionality at low cost
We have been using RHEV in our production environment since 3.0 and have I to say that the product continues to evolve with each release. The current version is very stable and offers all of the features we require from a virtualisation infrastructure platform. I am especially impressed with the self provision user portal and the performance of Spice as a remote desktop protocol, although it would be nice to have better client end support (OSX, IOS etc). One of the biggest lacking features is the ability to replicate virtual machine configurations to another RHEV environment for DR. Our development team addressed this by producing a python script which calls the REST API and replicates VM configuration allowing us to restore data into prebuilt VMs. www.quru.com/rvsr Overall we are…

It's possible to OEM and create a product with Ovirt as the main component.

Valuable Features:

The Ovirt component has flexibility, and is easy to perform integration within a  heterogenous data centre manager with OpenStack or ManageIQ.

Improvements to My Organization:

It has the possibility to OEM and create a great product with Ovirt as the main component.

Room for Improvement:

It needs a better administrator KB, similar to what Citrix XenDesktop has. Also, they don't know how to sell their great products and don’t really seems to be interested in taking care of their partners who trust and really know their products.

Other Advice:

If you have a heterogenous data centre that is specially focused on Linux platforms, this is safe money, and good if you are looking for automation. 

It also offers great integration with DevOps tools.

Disclosure: My company has a business relationship with this vendor other than being a customer: We have a joint OEM product based on the Ovirt component.

Did you encounter any issues with deployment, stability or scalability? If so, please describe. - Stability and bugs in previous 2.x versions

Did you previously use a different solution and if so, why did you switch? - No this was our first virtual platform

Before choosing this solution, did you evaluate other options? If so, which ones? - The choice was clear for us; it had to be open-source with commercial support

How would you rate the level of customer service and technical support? - The support we got so far from redhat as customers was great. You would probably not get better elsewhere

Was the initial setup straightforward or complex? In what ways? - Straightforward. Yes there is a great guide online at redhat on how to install this

Did you implement it in-house or through a vendor team? If through a vendor, how would you rate their work? - We installed it in-house as we are reseller and integrator

What is your ROI on this solution? - There is no investment in this product. As a reseller we can use it to test for free we pay every year a fixed cost as partner.

What was your original setup cost for this solution and what is your day-to-day cost of using it? - Free for us

What advice would you give to others looking into this solution? - I would say give it a look if you are looking for a virutalization platform. Most of the things can be done with rhev and the cost is much lower then with other commercial solutions. Since version 3 this product is mature and since version 3.1 most glitches where removed.

RHEV 3.2 is Quite Stable, Unlike Previous Versions
I am very pleased to say that I like Red Hat in many ways because of their innovations,working on new technology and improving day by day bringing it upto the expectations of customers with premium support available through out at all time. RHEV was launched as a web portal based access of virtual machines throughout the network which is used in organizations for different purposes with all virtualization features available today; earlier they were having problems with the product but now RHEV 3.2 is quite stable.

RHEV is excellent due to cost, performance and security.

Valuable Features:

RHEV costs are very low compared to other Virtualization products. RHEV hypervisor supports up to 160 cores and up to 2 TB of RAM on a host machine. Performance and security are key advantages of RHEV. One of the new features are transparent huge pages, where kernel dynamically creates large memory pages for virtual machines, which improves performance for most workloads by reducing the number of times that memory is accessed. It is open source, which means that it is available for use by every one. There is a “Power user portal” feature that helps developer and IT staff with a self-service interface that allows them to provision virtual machines, define templates, and be an administrator to their own environment.

Room for Improvement:

You need to buy support from red hat and you need to renew support every year in order to keep getting support from red hat. Some features are unavailable compared to leading visualization products. RHEV hyper-visor came later into the market than other leading visualization product.

Other Advice:

RHEV hyper visor is a cost effective solution for virtualization. Its work on kernel base virtualization systems. Its usage keep growing in the market.
