We performed a comparison between OpenNebula and VMware Aria Operations based on real PeerSpot user reviews.
Find out in this report how the two Cloud Management solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
"It also brings up a list of machines and if something is under-provisioned and needs more compute power it will tell you, 'This server needs more compute power, and we suggest you raise it up to this level.' It will even automatically do it for you. In Azure, you don't have to actually go into the cloud provider to resize. You can just say, 'Apply these resizes,' and Turbonomic uses some back-end APIs to make the changes for you."
"The tool provides the ability to look at the consumption utilization over a period of time and determine if we need to change that resource allocation based on the actual workload consumption, as opposed to how IT has configured it. Therefore, we have come to realize that a lot of our workloads are overprovisioned, and we are spending more money in the public cloud than we need to."
"On-premises, one advantage I find particularly appealing is the ability to create policies for automatic CPU and memory scaling based on demand."
"It became obvious to us that there was a lot more being offered in the product that we could leverage to ensure our VMware environment was running efficiently."
"Using this product helps us to reduce performance risk because it shows us where resources are needed but not yet allocated."
"The biggest value I'm getting out of VMTurbo right now is the complete hands-off management of equalizing the usage in my data center."
"The automated memory balancing, where it looks at whether it's being used in the most efficient way and adds or takes away memory, is the best part. If it didn't do that, it would be something that I would have to do. We have too many machines for one person to do that. The automation helps me in that it is done in a really efficient way and a balanced way because of the policies. It really helps."
"Rightsizing is valuable. Its recommendations are pretty good."
"OpenNebula has very good integration with SAP Storage."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."
"It's easy to integrate OpenNebula with our IT systems."
"The most valuable feature of OpenNebula is that it scales very well."
"It makes maintenance very easy and stress-free for our teams."
"The service feature appeals most to us, thus it is the most valuable."
"The live migration feature has been great and is something we use very often."
"It has reduced the time it takes to troubleshoot issues. We have customers trying to pinpoint and isolate issues using vROps. The information it provides helps them to pinpoint the issue a lot faster and resolve anything a lot quicker as well. They have a lot less downtime."
"The stability in vRealize has been great. We've had no outages nor impacts. The upgrade process has been great so far."
"The most valuable feature is the way you can look at your virtual machine and see if it's using too many resources or not enough, and you can add resources to it if you need to, or take some away to save on them."
"What we do, as a whole for our group... is storage virtualization and the compute side. This product brings all those pieces into one interface and now we can actually correlate data between them."
"It provides us with predictive analysis of the capacity, helping us plan the scalability of resources."
"It helps an organization quickly create test and dev environments for developers to come up with new software and patch tests."
"The most valuable feature is determining if more resources are needed, at the hypervisor level, based on the workload of the virtual machines that we have in our environment."
"It is intuitive and user-friendly. As you go through it, with some of the wizards and some of the interfaces that are out there, I think it's fairly easy to step through, even when we're training new employees to work with the product."
"The one point is the reporting. We do have reports out of it, but they're not the level of graphical detail I would like."
"While the product is fairly intuitive and easy to use once you learn it, it can be quite daunting until you have undergone a bit of training."
"They could add a few more reports. They could also be a bit more granular. While they have reports, sometimes it is hard to figure out what you are looking for just by looking at the date."
"The deployment process is a little tricky. It wasn't hard for me because I have pretty in-depth knowledge of Kubernetes, and their software runs on Kubernetes. To deploy it or upgrade it, you have to be able to follow steps and use the Kubernetes command line, or you'll need someone to come in and do it for you."
"Recovering resources when they're not needed is not as optimized as it could be."
"The old interface was not the clearest UI in some areas, and could be quite intimidating when first using the tool."
"The issue for us with the automation is we are considering starting to do the hot adds, but there are some problems with Windows Server 2019 and hot adds. It is a little buggy. So, if we turn that on with a cluster that has a lot of Windows 2019 Servers, then we would see a blue screen along with a lot of applications as well. Depending on what you are adding, cores or memory, it doesn't necessarily even take advantage of that at that moment. A reboot may be required, and we can't do that until later. So, that decreases the benefit of the real-time. For us, there is a lot of risk with real-time."
"Additional interfaces would be helpful."
"It should have a simple REST API like most other tools. It's the industry standard format. An XML-RPC API gives you an XML document that you have to convert and then do something with that. REST API endpoint provides outputs in a JSON document. I would also like to see support for user data or heat templates, which OpenStack offers, but OpenNebula doesn't have this yet."
"The storage feature that they have is a bit confusing."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"The protocol for clusterization is rough and doesn't work well."
"The UI, monitoring, and alerting could benefit from further improvements."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"There are no payment gateways in OpenNebula."
"An area for improvement would be application-level monitoring."
"The room for improvement is in the definition of the metrics. There are millions of metrics inside the solution, but there is no documentation from VMware for what those exact metrics are. That is a trouble point at times."
"In the past, when we have raised priority one tickets and they have sent us level one engineers. This wasted time because the L1 was only able to perform the troubleshooting steps that we had already completed."
"If the cost of the license could be cheaper, it would be good."
"The database services in the tool as backup services are friendly and can be deployed in the release to production. However, in the new features, I would like to include more online documentation that can help service generate early alerts."
"We use a large installation of this solution with multiple nodes and so the setup was pretty complex."
"In terms of what could be improved or added to VMware vRealize Operations (vROps), from my experience, it needs more work in the ITSM space because my company never used it as an IT service management tool."
"The integration points can use improvement. We currently use a lot of third-party management packs to get insights for SQL, HP or Dell EMC. If we could have more integration built in as a standard feature that would make it slightly better."
