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 service feature appeals most to us, thus it is the most valuable."
"With a single click, we could set things up and initiate them."
"The live migration feature has been great and is something we use very often."
"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 has very good integration with SAP Storage."
"The most valuable feature of OpenNebula is that it scales very well."
"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."
"For me, it's the dashboard."
"We do not have any problems with the product. It solves our problems. We now know if something is on the console and if there really is a problem. Before this, we had a lot of false positives. It digs into the problems and then at the end it just drops it."
"VM rightsizing is another very good feature and capacity planning is something else that I like about it."
"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."
"vRealize has products created especially for virtualized infrastructure by VMware. Its main features are great."
"It provides my team the awareness to see what's going on with the nodes and the clusters. It will then either rebalance them or allow the automation to rebalance them for us."
"The most valuable feature is the ability to get a view of our entire environment in a single pane of glass. We're a very large company, so going from one interface to another to troubleshoot an issue, or even just to get capacity information, is time-consuming and not efficient. Being able to go to one place and get that information is very helpful."
"We receive an overview from the dashboard of what is happening in our environment."
"Hosting platforms are limited so the deployment process needs improvement."
"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."
"There are no payment gateways in OpenNebula."
"The protocol for clusterization is rough and doesn't work well."
"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."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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."
"It is a bit complex, so you need to spend time with it."
"There is room for improvement when it comes to the integration with Active Directory. Sometimes I need to log in to the application using my Active Directory account, instead of using the regular admin for vRealize Operations. If I want to deploy this tool to more users, I need that."
"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 have an Enterprise Plus license, so there's a long list of stuff that you get with the Enterprise Plus license, and I'd like to see a better integration of all the vRealize components."
"There are some metrics that are not included in the canned set, that we've created. They call them super metrics in the tool, where you create your own metric. But the super metrics are not really reliable. It might be because we didn't create them correctly, although we did have help from VMware. They also don't translate into newer versions like a canned metric would. One of them is a vCPU to pCPU ratio. That's one that is missing, which should be very simple for them to collect."
"If I put on the hat of a client, I would say cost needs improvement. For clients with reasonable-sized infrastructure farms, you're looking at licensing at either per socket or per VM, and if you have an installation of any size, you're doing it per socket, and the per-socket licensing is a little heavy. Per VM license, if they have large numbers of VM, it is just not practical."
"When you deploy it as a single node, it's more stable than if you have multiple nodes. We've had some issues with this."
"It was not intuitive and user-friendly in the versions leading up to 6.5."
