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

"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."

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

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

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

"The service feature appeals most to us, thus it is the most valuable."

"It is quite easy to deploy."

"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."

More OpenNebula pros

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

"When there is an issue at the disk level in vSAN, vROps gives us an alarm that the issue is happening on particular disks. Other solutions cannot give this type of alert for vCenter. Even vCenter cannot give that type of information."

"It does exactly what it's supposed to do, giving all your coworkers, management, and users a dashboard that shows the current state of the entire vSphere ecosystem, which is very nice to have."

"It can save the organization money if you're using it right."

"If you are looking at the solution, I say, "Go for it." It has been good for us."

"You can put it on the whole VM infrastructure, and anywhere your VMs are, you have vROps that can act on that space."

"The most valuable feature is the ability to monitor our compute and that it tells us when we must buy new storage or a new host."

"The scalability is great. We have never had any issues with it being unable to size properly in our environment."

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."

"They should add more features like object storage."

"The protocol for clusterization is rough and doesn't work well."

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

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

"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."

"Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing."

More OpenNebula cons

"As they're able to add in more vendors for hardware to be able to pull information from different firewalls, switches, or other vendors, I would like to see where we can get more of a complete view of what's going on in the network. That would make this solution better."

"Not a ton of value yet, but I can see it on the fairly near horizon."

"It's complex and not intuitive. It has a long learning process. It can be frustrating trying to get the correct information from it."

"I find it to be a little chuggish sometimes; it can be very slow."

"There was a collection bug and some alert bugs (didn’t show all the alerts and popped up fake alarms)."

"They should include an integration feature through which we can connect to different vendors by installing a small plugin."

"I sure don't find the solution to be intuitive or user-friendly. It takes a lot of time to get familiar with the interface."

"Maybe improve the user interface, immediate access to data, and make it easier to get reports, from the application owner's perspective, not for me."

More VMware Aria Operations cons

Pricing and Cost Advice

"OpenNebula gives good value for money."

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

"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."

"VRA is very expensive but OpenNebula is free."

"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."

"I would like to see a free offering. Cost is always a factor in any sort of line. Obviously, the value added is there and it's worth it."

"The predictive analysis of the infrastructure helps our customers to reduce downtime and improve capacity planning. Issues are fixed faster with vROps."

"Don't overallocate! This means that you don't have to buy many hosts. You can save money that way."

"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.'"

"So, besides the license overall, you have to pay for the type of support you want. With the license, there is a support cost as well."

"The licensing is quite expensive for our company."

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

"The licensing model is annual. Compared to the price of other products, VMware vRealize Operations (vROps) is a bit on the high side. If it could be cheaper, it would be good."
