Executive SummaryUpdated on Dec 17, 2024

VMware Aria Automation and OpenNebula are competitors in the cloud management space. VMware Aria Automation holds the upper hand with extensive automation features and robust integration capabilities, which can be critical for enterprises seeking comprehensive cloud management.

Features: VMware Aria Automation's standout features include mass parallel administration, remote CLI access, and vendor-specific integrations such as SaltStack for faster deployment. It offers advanced orchestration capabilities and is particularly strong in cloud management. OpenNebula's simplicity and lightweight design are key features, making it highly suitable for straightforward deployments. It effectively supports various hypervisors and is preferred for on-premises deployments.

Room for Improvement: VMware Aria Automation requires better documentation, more intuitive UI, and enhanced template management. There's also a need for improved integration with platforms like Azure. OpenNebula needs enhancements in documentation and managing complex environments, alongside improvements in its marketplace and template creation support.

Ease of Deployment and Customer Service: VMware Aria Automation supports both on-premises and hybrid environments, offering knowledgeable technical support, although it can vary in responsiveness due to customization capabilities. OpenNebula is user-friendly for on-premises deployments and relies on community-based support, which is collaborative but lacks direct support compared to VMware's tiered system.

Pricing and ROI: VMware Aria Automation is a paid product and is often seen as expensive but provides valuable features and integration capabilities that can justify the cost for enterprises. It offers potential ROI through improved automation and reduced deployment times. OpenNebula, being open-source, offers a cost-effective alternative with lower overhead, providing good value for those seeking flexibility without significant investments, though potentially offering less enterprise-level functionality.

Robust with great CLI tools and UI

I've found OpenNebula upgrades to be more complex than those of some of the competitors and the support to be mediocre. I would also like to see more and better ancillary tools related to OpenNebula, for example, more robust tools for backups, user support, etc. The support knows their software stack reasonably well. However, OpenNebula depends on so many open-source projects that they lack expertise. As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today.

Significantly streamlined operations with good automation that helps with simplifying workflows

It helps me build a big catalog and provide it to my end users. It helps us automate the workflow of creating many VMs and the TensorFlow key method. I do not meet many people to operate it live beforehand. It operates for both of my products, but as a product, it is complicated to integrate and automate with other products.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

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

"OpenNebula has very good integration with SAP Storage."

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

"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."

"The live migration feature has been great and is something we use very often."

"It is quite easy to deploy."

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

More OpenNebula pros

"We haven't hit any limits yet, scalability is good."

"The product is very user-friendly."

"vRA provides that single pane of glass for our cloud tenants to deploy, monitor, access, and manage their VMs/guest operating systems."

"Scalability is perfect. We haven't had any issues."

"It is mostly for our tech support to test new versions, find bugs, and troubleshoot what is happening at customer sites."

"The most valuable feature is being able to deploy a virtual machine from a low level. We can automate everything including network configuration, firewall configuration, storage, storage attachment, OS deployment, middleware, and so forth."

"The solution is intuitive and user-friendly. E.g., you have less number of logins."

"It's quite user friendly. Everyone can use it, even non-technical people. This is good, since we use it to build a self-service portal which even users with not a lot of technical background can use."

More VMware Aria Automation pros

Cons

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

"They should add more features like object storage."

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

"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."

"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."

"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."

"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

"The solution is intuitive, but not necessarily user-friendly. In particular, it's the documentation. It's a lot of going-through-the-weeds types of scenarios. There is just an abundance of information, so it's a matter of understanding how the objects or the relationships exist, and then, obviously, being able to access that information and knowing how to make use of it."

"The basic support is not there for Google Cloud and Azure. They are unable to provision nor do cost controls. Google is still left out. It is great that they have done AWS, but we are a retailer which means nothing to us because it is a competitor. Azure is good, but Google is where a lot of our development environments are."

"I think they could probably do more if they created more actions and more use cases to automate things."

"There is a little bit of pain when it comes to libraries and what is needed to run the product."

"Deploying and configuring the solution takes a lot of time."

"The setup needs coding. It's not easy. It's not straightforward."

"We upgraded twice. The last upgrade was a bit problematic."

"It has a learning curve."

More VMware Aria Automation cons

Pricing and Cost Advice

"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 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."

"The solution is open source so is free."

"VRA is very expensive but OpenNebula is free."

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

"I would rate it high because, compared to other solutions, VMware’s pricing is quite expensive. VMware products have become significantly more costly in recent years, leading to higher costs."

"vRealize automation really should be a front door to the whole VMware suite of products."

"We do plan to see ROI with any new implementation of new technologies being implemented within our environment."

"The solution is pretty expensive but provides good workload management."

"It is an expensive product. After VMware's acquisition by Broadcom, there was a rise in the price of VMware Aria Automation."

"A simplified version for small businesses would be good."

"It is pricey for what you get."

"VMware Aria Automation is expensive."
