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."I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."
"OpenNebula is lightweight, stable, and easy to customize."
"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."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"It is quite easy to deploy."
"The most valuable feature of OpenNebula is that it scales very well."
"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."
"It makes maintenance very easy and stress-free for our teams."
"The automation brings insight into how we will grow. I can look at it, then make my recommendations on what equipment we need to do for the next fiscal year."
"This solution is most definitely scalable. We've already gone back to the drawing board and specifically designed it from the ground up, to be scalable with the size of our environment moving forward."
"It provides optimization recommendations for data centers, cluster workload migrations, and vSAN."
"The most valuable feature is all the metrics we get. They're really good. Being able to drill down and find out where the CPU and memory bottlenecks are and being able to tune them is really helpful."
"It helps us by our using the Troubleshooting Dashboard to see if there is contention on the VM that's causing performance issues or if it's a problem with the resources it has or if it doesn't have enough. It helps lower the troubleshooting time on virtual machines."
"One of the best features is the monitoring. It gives you proactive recommendations, based on the information that you have. It recommends changes. For example, if an ESX service is heavily loaded, it will tell you to make some changes, such as storage optimizations. Every tool does monitoring, but this one gives you more proactive monitoring, with the recommendations and actions that are needed."
"It does exactly what I program it to do at this point, which is to tell me if I've got machines running out of disk space or over-utilizing CPU or memory. The monitoring component of it is the most valuable feature."
"It gives us a single pane of glass to look at whenever we're trying to troubleshoot issues, so we can go to one place as opposed to multiple places."
"An area for improvement in OpenNebula is the number of features it has. The solution doesn't have that many cloud features compared to other solutions. You'd say, "Okay, simplicity over a rich feature list?" Some say, "No, I need a big machine or a cloud interface for my customers to manage resources. I don't have to go and do it for them." Some people do it that way, and it works, but I'd like to improve the limited features in OpenNebula."
"There are no payment gateways in OpenNebula."
"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."
"They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work."
"The UI, monitoring, and alerting could benefit from further improvements."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"They should add more features like object storage."
"The storage feature that they have is a bit confusing."
"One way the solution could be improved, in my opinion: management packs, more native management packs with API."
"I would like to go back in history on the performance data and blank out some of that performance data so that it isn't used in calculations."
"It can be user-friendly once you get the dashboard set up but it can be complicated to get the information you want, the way you want it. Finally, if there were an easier way to share dashboards, that would be a big one."
"The biggest room for improvement would be the customizability of the alerting function. The emails that come through are somewhat difficult to tailor along with the information contained within them and how they are laid out."
"On a specific version, it has been stable. But the whole point of the tool is historical data and, twice now, we have lost all of our historical data, as we've tried to move to the next version of the tool. That really removes a lot of the functionality that we've purchased the tool for."
"If you want to automate the resizing of machines, you should be able to schedule it, so it happens at two in the morning instead of right now, because if you do it in the middle of a workday that's a big no-no. Automation should be a bit more intuitive."
"In the next release, vROps should add integration with Apache OpenStack."
"I rated this solution a nine because I haven't had any issues with it and it has been intuitive and easy to use. I don't know it well enough to give it a ten."
