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

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

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

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

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

"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."

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

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

More OpenNebula pros

"The alerting is probably the most valuable feature of the product, because if issues come up, we can tell right away to look in the system, dive a little deeper and see if there's a real problem and if so, we can fix it before there's an outage."

"The vRealize Operations Manager gives you complete insight of the VMware environment, with a completely insightful, very clean, simple dashboard that makes it easy for anyone to understand what is wrong and how it needs to be fixed."

"The most valuable feature is the ability to right-size a workload, based on historical data for that workload. It also allows us to "sanity-check" the entire infrastructure by getting monthly reports on how everything is performing and where we can make improvements. That's all done automatically, without any administrator involvement."

"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."

"vROps would be my advice because it's simple to use, you have a panel to very quickly identify trouble, eventual problems; and it's easy to troubleshoot."

"My advice would be, just go ahead and buy it, because it's going to be leaps and bounds ahead of doing it the hard way and puts it all in one place while giving you capacity planning and a better idea of what your actual capacity is over time."

"What I find most valuable is its simplicity, which allows us to seamlessly migrate views from one physical server to another, be it due to resource overloads or transitioning from one set of disks to another."

"VMware does a really good job of integrating all of their tools together, whereas you get some third parties where they kind of haphazardly integrate in, and they may or may not stay well-integrated."

More VMware Aria Operations pros

Cons

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

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

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

"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."

"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."

"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."

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

"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

"Honestly, I don't think it's as good as it used to be. I think it's gone downhill a little bit."

"I rated this solution a nine because I haven't had any issues with it and it has been intuitive and easy to use. I don't know it well enough to give it a ten."

"I haven't been too impressed. There seems to be a lot of running around or not hearing back."

"There's room for improvement in the upgrade process. It always becomes a bit of a challenge, and the one big thing for us is we have no means of creating a CICD upgrade process for it."

"Pricing is the only concern I have."

"If you want to automate the resizing of machines, you should be able to schedule it, so it happens at two in the morning instead of right now, because if you do it in the middle of a workday that's a big no-no. Automation should be a bit more intuitive."

"If I put on the hat of a client, I would say cost needs improvement."

"If I had to think of one thing that could be improved, I would probably lean towards making it easier to pull dashboards from vRealize Operations into other products, like a company-branded dashboard that would display in a NOC."

Pricing and Cost Advice

"VRA is very expensive but OpenNebula is free."

"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."

"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."

"OpenNebula gives good value for money."

"The solution is open source so is free."

"Bundle it in with your license rather than buying it as a separate product. It saves a lot of money that way."

"Pricing could always be cheaper, but it's acceptable."

"I have reduced the time to troubleshoot for my customers."

"The billing is complicated because every country has a different option. Here in Chile, we don't pay for this kind of service with the Chilean pesos. We use another currency. In the future, I think vROps needs to work with governments for a native solution."

"vRealize Operations has proved to be a cost effective solution for our big environment."

"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."

"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."

"I rate the solution's pricing a seven out of ten."
