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.

FOURES Jean-Philippe

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

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

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

"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."

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

"OpenNebula is lightweight, stable, and easy to customize."

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

"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."

"For our use case, we found the solution to be the best fit when dealing with infrastructure services."

More OpenNebula pros

"I would definitely recommend this solution."

"vROps has helped us to reduce the costs and increase the efficiency, because it has a lot of features that tell you where things are going wrong."

"Valuable features include trending of performance and capacity. Also, being able to dive into some more detailed analysis of performance metrics and compare them to a baseline of what's normal for particular time frames."

"The most valuable features of VMware Aria Operations include monitoring CPU, memory, and storage."

"You log in, you see everything that's happening right then. We can also export that, get information, print it out, show it to people. That's a big deal. People want to see that transparency. It's great that way."

"vRealize Operations Manager gives us more detail and is best of breed when it comes to monitoring."

"The product's initial setup phase is straightforward."

"This solution has helped to reduce time to troubleshoot issues, improve quality of service to users, and provide costs savings through higher capacity utilization."

More VMware Aria Operations pros

Cons

"They should add more features like object storage."

"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."

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

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

"There are no payment gateways in OpenNebula."

"Hosting platforms are limited so the deployment process needs improvement."

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

More OpenNebula cons

"On occasion, we can't even use some of the metrics because of the way our environment is set up; I can't turn it off for this pool and then have it on for this pool."

"vRLI still needs a lot of improvement to even start comparing with the market leader, Splunk, in terms of data analysis and customized charts/reports generation."

"I would probably like to see better recommendations. I think sometimes the recommendations for performance optimizations tend to be a little too simplistic."

"Easier management and it should be more user-friendly. When you look at it, and you see a lot of badges, you think, "Oh my god, that looks terrible.""

"It is quite expensive and if you just implement it just because you can then you won't get any benefit from it. You have to think through and plan ahead. You have to understand what the issues are that you want to solve with this solution. Otherwise, this solution is a waste of money."

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

"There are some distribution issues, and there is not enough information on the portal."

"It gets a little bit kludgy – slow, sluggish, takes a while – when it gets bigger."

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."

"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."

"VRA is very expensive but OpenNebula is free."

"OpenNebula gives good value for money."

"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."

"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."

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

"Our manpower costs have been reduced due to the automation in conjunction with the usage of the dashboard."

"The solution is costly."

"The solution is slightly expensive."

"The pricing is a little bit expensive. Licensing is an issue because there are always changes, and by that I mean cost increases. And that's not only for vROps but for VMware, vSphere, and all the products that are involved."

"The pricing: It's expensive."

"We have seen good ROI results. It has made our lives easier."
