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.

Products Manager at a tech services company with 501-1,000 employees

Reliable, simple to manage, and offers great technical support

The support of VXLAN fits with our network management. Thanks to this we can propose mixed solutions using virtual resources on OpenNebula and bare metal servers hosted in our facilities linked to each other on the sale network. This use case is very useful when some applications need bare metal power (Kubernetes workers, huge databases, AI models computations, et cetera). The cluster management is very useful for splitting our different clusters (mutual vs dedicated). We can manage deployments and capacity planning without pain. The API is also really simple and it helped us to develop the Terraform provider to manage OpenNebula like any other cloud infrastructure.

Senior System Network Analyst at Net spa

Have faced limitations due to high costs but have maintained reliability over time

The primary issue is the pricing, which is very expensive for my company's budget. We cannot afford to pay such a large fee. We are not Microsoft or BMW; we are a small company. As a small company, I have no power to negotiate directly with VMware. Perhaps larger companies have more opportunity to contract directly with VMware, but I do not have that leverage. The only path I can follow is to change solutions. Net.spA is a company working in the field of waste management. We are not a technological company, so we do not have a large margin to justify purchasing and maintaining the VMware infrastructure at current costs.

Quotes from Members

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

Pros

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

"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."

"It is quite easy to deploy."

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

"It's easy to integrate OpenNebula with our IT systems."

"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."

"It has enabled us to decrease the optics by around 55 to 60%."

More OpenNebula pros

"The most valuable features of VMware Aria Operations are its stability, ease of use, and extensive range of features."

"It has also definitely reduced the time to troubleshoot issues. The fact that it gives us that single pane of glass to look for stuff, that's the first stop whenever we start troubleshooting."

"vRealize has a very nice dashboard. It integrates well with other products such as those from Oracle."

"We are in a better position from an IT point of view; we can actually show management our plan based on growth, whatever growth they're looking for within the environment, as well as be proactive."

"Our business is built around testing, measurement, and performance measurement and vROps is the primary tool."

"If you're not using it, certainly go out and get it."

"Overall, this is a good product that is easy to install and use, and integration with other products is smooth."

"The tool helped the organization in all monitoring tasks when being delivered as a service for customers helps them to generate early alarm templates, being a cloud service provider is delivered as part of the IaaS to generate memory consumptions processing and storage additionally can be configured parameters such as networking and services that are configured on virtual machines."

More VMware Aria Operations pros

Cons

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."

"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."

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

"They should add more features like object storage."

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

"I would like to see OpenNebula add more integration with REST API. XML-RPC API is good, but it becomes a pain to form a resting output."

More OpenNebula cons

"I think the dev ops for Horizon need improvement."

"I think they need to make the UI a little bit more simplistic. It can be a little overwhelming for people who have never used the tool before."

"One of my biggest complaints is that I wish there was a better, consolidated dashboard on the landing page when you first log in."

"The room for improvement is in the definition of the metrics. There are millions of metrics inside the solution, but there is no documentation from VMware for what those exact metrics are. That is a trouble point at times."

"They should have more automation features for database management."

"At first, it was not so user-friendly because there was so much information that we were lost."

"For the most part, we have found it to be user-friendly. It has gotten better over time since the first version of vROps that I used. The interface has really improved since then."

"Some of the thresholds and what not are a little tricky to set up, and that's where we're struggling right now; our operations team isn't really managing those properly."

Pricing and Cost Advice

"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."

"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."

"The solution is open source so is free."

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

"OpenNebula gives good value for money."

"The solution has a huge cost. If we could just have one license covering everything that vROps can do, that would be great. I would prefer it this way."

"It was cost effective, because it fixed our problems."

"vROps is a bit expensive and that's a reason that small clients say, 'No, I don't think we need this.' From a pricing perspective, it is quite steep. But 'expensive' is relative, depending on what you need. Others might say, 'It is expensive, but I think we can use it to better our environment.'"

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

"The solution is costly."

"The optimization is a huge return on investment alone."

"The solution has helped to reduce the time to troubleshoot issues."

"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."
