Executive SummaryUpdated on Dec 17, 2024

VMware Aria Operations and OpenNebula compete in the cloud management category. Based on the data, VMware Aria Operations has the upper hand due to its advanced analytics and predictive insights specifically tailored for VMware environments.

Features: VMware Aria Operations is distinguished by real-time analytics, integration with vCenter/ESXI, and dynamic thresholds, which provide predictive insights into VMware environments. It offers capacity management and proactivity through detailed metrics for issue prevention. OpenNebula, meanwhile, is noted for its flexibility and adaptability across various platforms while being less specialized in VMware contexts.

Room for Improvement: VMware Aria Operations could enhance user engagement by simplifying its reporting features and improving the user interface for beginners. Additionally, expanding integration capabilities with third-party tools would extend its applicability beyond VMware. OpenNebula needs to improve its documentation and customer support for clearer communication. Of note, the platform would benefit from more robust community backing and quicker feature updates.

Ease of Deployment and Customer Service: VMware Aria Operations supports on-premises, hybrid, and private cloud deployments, with a recognized strong technical support network. However, reaching advanced support levels could be improved. OpenNebula is favored for its straightforward setup for on-premises and public cloud deployments, but it requires clearer communication channels and faster customer support response times.

Pricing and ROI: VMware Aria Operations is on the higher end of the pricing spectrum, making it more appealing to larger enterprises with specific VMware needs, substantiated by a significant ROI in environments heavily utilizing VMware. OpenNebula offers a cost-effective open-source alternative with lower upfront and operational costs, making it desirable for budget-conscious scenarios, albeit with some limitations in advanced features compared to VMware Aria Operations.

Manager, DevOps System Engineering team at MX

Robust with great CLI tools and UI

I've found OpenNebula upgrades to be more complex than those of some of the competitors and the support to be mediocre. I would also like to see more and better ancillary tools related to OpenNebula, for example, more robust tools for backups, user support, etc. The support knows their software stack reasonably well. However, OpenNebula depends on so many open-source projects that they lack expertise. As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today.

Manage and monitor crucial banking operations with deep logging and efficient alerting

The most valuable features of VMware Aria Operations include its excellent monitoring capabilities. It allows me to perform deep monitoring and logging of the entire environment, providing a quick alarm and warning system through email. These features help me in efficiently managing virtual machines. The solution also offers easy access to VMware KB articles for problem resolution, ensuring quick access to troubleshooting information.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

"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."

"The most valuable feature of OpenNebula is that it scales very well."

"With a single click, we could set things up and initiate them."

"It makes maintenance very easy and stress-free for our teams."

"It is quite easy to deploy."

"The solution provides templates for configurations that can easily be exchanged to VMs."

More OpenNebula pros

"Their technical support is good. We haven't had too much use for them."

"It is stable. I don't have any problems with this product and upgrades are very easy because it's just click two buttons and next, next, next, finish."

"It visualizes stuff better, so we can pinpoint or see problems"

"What I like most about VMware vRealize Operations (vROps) is how it integrates into the vCenter. You'll get a similar hierarchical view of your host, your VMs, your resource pools, etc. I also like the granularity, particularly the fact that you could go pretty deep into the metrics and data retention as well. You could go far back several months to try and plot performance trends, eventually leading up to an issue or post-incident management. I also like the plugins in VMware vRealize Operations (vROps). I find the plugins good, especially because you could plug those into Dell. For example, there was a way to visualize how your Dell infrastructure is performing. You could build dashboards, even custom dashboards for your operational teams. You could take a look at what was going on and also look into people doing incident management, troubleshooting, etc. You could customize your experience with VMware vRealize Operations (vROps), and I found that good as well. I also like the UI of VMware vRealize Operations (vROps) because it's nice and very, very fresh."

"There's a feature known as Smart Alerts in vRealize Operations, which I have found to be useful if there's anything going wrong in the infrastructure. What usually happens is that you get so many alerts that you become confused. Smart Alerts give you visibility into your infrastructure and also recommend how to fix the situation. That's a feature which I'm really a fan of."

"I like that it's integrated with the other suite of tools. That's a big plus for the tool. It's well-integrated with Log Insight. We use that integration quite a bit."

"It is easy to drill down directly to the root cause of a problem. It goes from network to storage and having access to all the metrics. When you run 100 percent virtual, then everything is in one tool."

"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."

More VMware Aria Operations pros

Cons

"There are no payment gateways in OpenNebula."

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

"The storage feature that they have is a bit confusing."

"They should add more features like object storage."

"The UI, monitoring, and alerting could benefit from further improvements."

"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."

More OpenNebula cons

"They should improve the vROps Federation Management Pack, so each customer can create a single pane of glass for multiple sites of vROps."

"There are some problems with integration, particularly with Slack, though these have been improved in the latest release."

"We would like easier customer reporting, because to do customer reports, we have to do a lot of programming."

"I would like to see them get a holistic view of the organization, not just focusing on the server and the state that it's running on but to widen that out from the end user all the way through. It's a key critical part but actually, it needs to bring outside of that, then to the networking elements and the inter-dependencies that are in hospital solutions."

"I know that they talk a lot about AI and a sort of forecasting ahead of time. It's a good application, but it has to wait for a certain period of time to actually do an analysis. If it would give you that ahead of time, or even forecasting, it would be really improved."

"I would like to see more integration between vRealize Operations, Log Insight, and Network Insight. It would be nice if they worked a bit better together."

"I can't pinpoint any specific areas for improvement at the moment, though there is always room for better pricing, licensing options, and potential enhancements in the user interface or customization."

"The VMware Aria Operations solution is a very technical product and is not for everyone. As a top-of-the-chain VMware tool, it is only normal that it has a learning curve. While the UI has been improved, it may still be difficult for some users. The solution has a lot of functionality and can monitor all areas of infrastructure, such as storage and network."

More VMware Aria Operations cons

Pricing and Cost Advice

"We use the Community Edition, rather than the Enterprise Edition."

"The solution is open source so is free."

"OpenNebula gives good value for money."

"VRA is very expensive but OpenNebula is free."

"The licensing for OpenNebula used to be free, but now it's no longer free. A customer contacted me asking to move to another provider because of the changes in the licensing terms for OpenNebula. I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

"OpenNebuoa has recently come up with a new subscription model that is economical and a lot of new customers are choosing this as it is an easy subscription model."

"There's a smaller category that stands out due to its affordability, especially for recent versions, which I rate as four or five in terms of value. However, if you're looking for a vCenter with older, more advanced features, it comes at a significantly higher cost, and I would rate it around ten. They provide us with a choice between a recent version and one integrated, and I lean towards the former."

"If you compare the prices of VMware and the cloud solutions along with the components that you may use, I feel that it may be costly."

"Most small users don't adopt VMware Aria Operations until it's necessary. Small businesses are looking for it, too. We need more monitoring and insights, so we're analyzing solutions to help us out here. I rate the solution’s pricing a five out of ten."

"We would like to build custom dashboards in the standard license. Right now, this is available in the enterprise license, not the standard license."

"Every VMware product is a licensing challenge. It's always costly. It's based on processors. From a technical side, the product is very good. The challenging part is always the licensing. They should have some kind of alternate pricing models."

"The licensing is quite expensive for our company."

"We have seen huge ROI. It has certainly reduced troubleshooting."

"When we last did a comparison of solutions, the pricing was equal or similar."
