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."The most valuable feature of OpenNebula is that it scales very well."
"The live migration feature has been great and is something we use very often."
"OpenNebula has very good integration with SAP Storage."
"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 is quite easy to deploy."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"OpenNebula is lightweight, stable, and easy to customize."
"We went from using industry standard KPIs to going to a complete on-demand model based on the algorithms from vRealize Operations. It has enabled us to drive more utilization out of our existing compute infrastructure to the point where, for a period of six months, we didn't purchase a single server or any additional compute. We were able to continue to sweat our existing assets."
"It has helped us to reduce the amount of VM sprawl, VMs that are not necessarily used. We can then reclaim resources such as memory, CPU, and storage."
"It can compare hardware to software, and I have all the information in one place."
"It has enhanced our ability to troubleshoot and effectively manage our solutions to understand what clusters are having issues and diagnose those programs right away, so we can be proactive."
"I like the monitoring aspect. One of the biggest things in our environment is being able to see what the entire vCenter environment looks like. The health status, being able to determine when we're having issues with resources, utilization, memory, or CPU."
"It enables me to anticipate our system needs, to be able to know if a host is overloaded, to be able to move things off of it... vROps has really helped us focus in on where the trouble spots are, to be able to alleviate those problems before they even become problems, so it's great."
"Based on those usage patterns, we can determine when our best maintenance times are and when we need to scale things up or down."
"The ease of installation and configuration is the most valuable feature, especially for VMware and the cloud."
"The storage feature that they have is a bit confusing."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"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 should add more features like object storage."
"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."
"The protocol for clusterization is rough and doesn't work well."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"It is quite expensive and if you just implement it just because you can then you won't get any benefit from it. You have to think through and plan ahead. You have to understand what the issues are that you want to solve with this solution. Otherwise, this solution is a waste of money."
"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."
"I would like to see more functionality. I would also like to see better support, because the pack that we use, the Horizon, it's an additional pack. It's not currently actually built by VMware, it's built by a separate company. When they merge the two, there will be better support in the future."
"We have started to do containers and I would like to see a feature to monitor our container infrastructure. If we can do our monitoring and performance troubleshooting of them through this tool, that would be a nice-to-have."
"The solution can improve by offering more flexible integration with other platforms or products, such as Hyper-V or Azure. Not everyone uses VMware. It would be beneficial to have a more open-source concept for integration, creating more visibility across multiple clouds."
"It wasn't exactly proactive. It was supposed to, but there were a lot of delays. It could also be because of our infrastructure and the way our network was set up. If vROps could be more proactive, that would be nice. It is nice to have the information beforehand, but when there is downtime, it takes a lot of time for us to be able to see an issue in real-time, which becomes a bit challenging. If there is a way to improve the data collection for the whole vCenter that would be nice because data collection takes a lot of time."
"In a previous version, you could click on a cluster to see a lot of information about efficiency, e.g., when you will run out of memory, CPU usage, and RAM in percentages. In newer versions, you see this information in megahertz and kilobytes, not percentage. I don't like this change so much. If you need to present information to your boss or Director of IT, the information would be better with a percentage. Now, you have only a big number and don't know the percentage of use that you are getting from the VMs. I don't know why they changed it, but I liked the percentage version more than getting the numbers for megahertz of memory. Also, kilobytes of memory is a very large number. For a simple view, gigabytes or terabytes is better."
"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."
