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 makes maintenance very easy and stress-free for our teams."
"OpenNebula is lightweight, stable, and easy to customize."
"It is quite easy to deploy."
"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."
"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."
"The most valuable feature of OpenNebula is that it scales very well."
"The service feature appeals most to us, thus it is the most valuable."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"From a scalability perspective, the nice thing about vROps is it's more of a horizontal scale model. As our workloads increase, as our vCenters and different environments grow, vROps is easy to scale to consume that capacity by just adding another node. That can help. It keeps it from getting bogged down from not having enough resources. We can easily add a node in, it takes the additional load, and keeps up with our growth."
"I like the fact that the performance is good and that it makes it easy to consolidate all your servers."
"It helps an organization quickly create test and dev environments for developers to come up with new software and patch tests."
"Through the trending analysis that we can do, it allowed us to quickly and easily right-size the capacity from a cluster."
"One of the most valuable features is the trending analysis of our environment to make capacity-planning decisions, in addition to providing real-time analysis of events."
"Heat maps are valuable."
"The capacity planning is one of the most valuable features. That is brilliant."
"It is a cloud-friendly application."
"There are no payment gateways in OpenNebula."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"The protocol for clusterization is rough and doesn't work well."
"The storage feature that they have is a bit confusing."
"VMware vRealize Operations (vROps) should improve instant monitoring. Currently, the monitoring is on an interval of five to ten minutes, if I want to know what is happening now I cannot."
"I want vROps to have wider compatibility with older hardware. In this country, many companies have older hardware, so sometimes we can't support all the newest features."
"It requires a lot of knowledge to manage. For example, if you are collecting a lot of data for analysis, the virtual appliance drive spaces can fill up. In this case, you need engineers who know how to expand those spaces."
"When you are at your lowest, support is pretty bad. They ask you dumb questions but when you come to second and upper service desk, it is much easier and much better to talk to and resolve the issue."
"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."
"In terms of user-friendliness, there are a lot of areas that take a lot of time to research and figure out what the information is actually telling me, so that I know how to better use the product and troubleshoot issues that I see. It would be nice if they could fine-tune the user-interface a little bit."
"At first, it was not so user-friendly because there was so much information that we were lost."
"There is a learning curve because it's a complex program. There is a lot to consume in terms of the metrics inside of it. That's the biggest hurdle: trying to understand all the places to go look."
