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.

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.

Automation has streamlined complex financial workflows but still needs more intuitive orchestration

Something to improve in VMware Aria Automation would be related to VCF 9, as I do not know what it is trying to bring because they exposed it as the solution of everything. So VCF 9 will bring VCF Automation and VCF Operations, the new product line of VMware. I have not seen what this brings or what else it includes. Maybe in the area of vRealize Orchestrator, this would be beneficial because VRO can do everything. Perhaps a more user-friendly way to use that tool would be helpful because the possibilities there are endless. I am looking for more user-friendly navigation in VMware Aria Automation.

Quotes from Members

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

Pros

"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."

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

"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."

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

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

"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."

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

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

More OpenNebula pros

"We have been able to integrate with AWS to deploy continuous delivery services with an extremely quick turnaround time."

"Our customers don't have to manage HVAC and space and cooling and all of those things that they used to have to do. Today, all they have to do is provision a server and manage their users."

"It's also absolutely easy and intuitive. It uses the same basic layout as the rest of the product suite so it's really easy to navigate, find your way around between the tabs and the areas."

"The automation function itself and how to group and publish those groupings is quite easy for customers to learn with Aria."

"The self-service capabilities are by far the best that we've seen in terms of features."

"The customer can set up multiple machine blueprints. Therefore, we are able to customize the template of three machines, then the customer can deploy without knowing anything about the IT business."

"States, pillars, and custom modules have all taken us a long way in achieving our goals."

"Deploying a patch on 200 systems is now just a click."

More VMware Aria Automation pros

Cons

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

"They should add more features like object storage."

"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."

"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."

"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 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."

More OpenNebula cons

"When you start to do a deployment where you need higher availability and more resiliency, then the complexity goes up drastically."

"The solution is intuitive, but not necessarily user-friendly. In particular, it's the documentation."

"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."

"It is not intuitive or user-friendly. It's complicated as heck. We actually hired VMware Professional Services to come in. I understand the newer version, which we're not quite on yet, is easier and that the interface is better. But the product is really a profession unto itself. The user interface could be improved on."

"I'm not aware if a UI exists or not."

"It was a complex setup. We had to use the consultant from VMware to make the solution work well."

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

"Automation or scripting should be simplified so that administrators who are not experts can have a better grasp of automation."

More VMware Aria Automation cons

Pricing and Cost Advice

"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."

"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."

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

"OpenNebula gives good value for money."

"The solution is open source so is free."

"It made the provisioning of the virtual machines easier and faster. We can react more quickly to customers' demands."

"It is an open-source product."

"So much can be done with the Open Source side, and especially for smaller shops. I personally think the pricing for Enterprise is hard to justify."

"There is confusion between licensing levels. There are three different licensed versions of vRealize Automation, and there are different things which can happen in each of them."

"As far as value is concerned, it has been essential to our environment. We have been able to deploy VMs quickly and the developers have their own sandbox, so they can spin up and destroy VMs at their own will."

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

"The pricing is very high."

"They should provide one license for all the sub-products."
