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.

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

"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."

"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."

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

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

"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."

"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."

"It is quite easy to deploy."

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

More OpenNebula pros

"Our ROI is that I can spend less time looking at issues, it's all there in the dashboard."

"In terms of uptime, it helps us to keep a better eye on our infrastructure, to be proactive before an outage occurs."

"As soon as we installed VDI, it just quickly showed us a ton of problems we were having we didn't even know about."

"The initial setup is quite easy and straightforward. The majority of the time, implementing vROps is not time-consuming."

"The most valuable features are the health tree and the alerts that tell us what's going on from a glance at the dashboard. As far as showing us where the problems are, what's useful is that it gives us suggested solutions to fix them, so that's helpful."

"The most valuable feature would be the reporting function and the central location for everything."

"The most valuable features are the Heat Maps, and the various graphs and reporting features it has."

"For me, it's the dashboard."

More VMware Aria Operations pros

Cons

"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."

"There are no payment gateways in OpenNebula."

"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."

"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."

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

"Template management also needs improvement in OpenNebula because it's inferior right now."

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

More OpenNebula cons

"It should have some more functionality in terms of getting some more third-party vendor application-level integration."

"Monitoring is useful but if the solution can't automate or function without my input, it's a waste of my time. That's where I found out there are some issues with this product, there are elements that are not as intuitive as they could or should be."

"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."

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

"Maybe some easier ways of getting some of the NSX monitoring products."

"Security has been a boom for companies in the last few years, and considering how important security is, there have been a lot of tools that offer better integrations. So, the current tool can be used for any integrations in any environment, which is something VMware is not yet that efficient at."

"If it's just there to monitor, what's the point? You could use other tools, but if you're trying to do more with less and you're spending a lot of money on rightsizing this and deploying it correctly, it'd be better if I'd actually get something more than just a nice dashboard."

"Stability is a significant area that needs improvement as I experience frequent disconnections and interruptions in data collection."

Pricing and Cost Advice

"OpenNebula gives good value for money."

"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."

"The solution is open source so is free."

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

"VRA is very expensive but OpenNebula is free."

"There has been a bit of cost savings in that we could decide to move workloads around a bit better."

"Five or six years ago, when we took it, it was a very good option. Now, I think I have to reevaluate, to be honest."

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

"Our budgets are always tight. We would like to have more features at lower licensing levels for easier access to them."

"The value that we get from vROps is okay. It could be cheaper."

"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."

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

"We have licenses on a three year basis. Licensing costs are much higher, but given the stability of the solution, it is a reasonable price."
