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

"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."

"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."

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

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

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

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

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

"OpenNebula has very good integration with SAP Storage."

More OpenNebula pros

"We are not constantly having to babysit or troubleshoot it. It does what it is designed to do, and it does a very good job of it."

"For me, it's the dashboard."

"It allows for a bit more transparency regarding consumption and it also helps us plan ahead."

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

"Vmware always gives us the best support. They are friendly to talk to and they understand the real impact of what's happening. They are trying to get into the issue as one of your team. They also fit into your working hours to solve your issues."

"Their technical support is good. We haven't had too much use for them."

"The reporting is a fantastic tool. It's a great tool for generating reports on different things, and for historically looking at performance metrics to help solve performance problems in an application stack."

"I've found vROps' predictive actions, monitoring, reporting, and provisioning features to be useful."

More VMware Aria Operations pros

Cons

"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."

"They should add more features like object storage."

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

"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."

"There are no payment gateways in OpenNebula."

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

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

"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."

More OpenNebula cons

"vROps is, by its nature, a very complex product."

"The initial setup was very straightforward. From the web interface, you can literally just go straight into actually installing vROps with very little previous knowledge required to get it up and running."

"In the beginning, I picked up an implementation that had been designed wrong from the ground up."

"They should make it easier to find those granular things that you're always looking for. You're always running into a situation where you want to use the tool to figure out a problem, but the amount of effort needed to delve into vROps and find the exact metric you're looking for is always so difficult."

"In the next release, vROps should add integration with Apache OpenStack."

"The solution must provide better training options to help us make the most of the tool."

"While the initial setup was somewhat straightforward, there is some complexity. Going forward, I would like there to be more clarity in the process. Because to complete the setup process, our team had to open up a case with the technical support, and they had to guide us through the process."

"The integration points can use improvement. We currently use a lot of third-party management packs to get insights for SQL, HP or Dell EMC. If we could have more integration built in as a standard feature that would make it slightly better."

More VMware Aria Operations cons

Pricing and Cost Advice

"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."

"OpenNebula gives good value for money."

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

"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 solution is open source so is free."

"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."

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

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

"If the VMs were trimmed, then we wouldn't have to buy as much software/hardware, and this means less licenses. While most of it is VMware licenses, which are relatively cheap, there are SQL licenses for Microsoft, and this is where we could start saving a lot of money."

"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 price of the solution is expensive."

"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.'"
