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

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

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

"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."

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

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

"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."

More OpenNebula pros

"It improves the work, making it better."

"For repeated installations and provisioning of VMs, we now have a clear definition of what has been installed, and we can monitor all that stuff."

"The most valuable feature of VMware Aria Automation is the versatile automation and deployments."

"It has improved our organization by automating some of our processes."

"SaltStack provides the capability necessary to truly streamline our SDLC and environment management."

"Now the customer can manage their own server requirements directly. This is very important because, before that, the process included signing off on forms and sending them to the IT Director. It took at least 10 days to create a VM and send it to the person who needed it. Now, it's no more than a half hour to activate a new VM at the customer's site."

"We use it to deploy databases and testing environments. It spins up quickly and also break down fast."

"Our speed of provisioning has improved. We used to build systems manually, which would take four hours or a day. Nowadays we're able to spin something up off a template... and it takes about 20 minutes."

More VMware Aria Automation 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 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."

"They should add more features like object storage."

"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."

"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."

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

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

More OpenNebula cons

"Once you get in there and start to understand the product, it is more intuitive. However, for somebody coming in from the outside, it takes a while to understand it."

"In general, it took us a long time to get it off the ground. We had a lot of issues upfront and we determined that we just needed to scrap it."

"I have not found this solution to be user-friendly. It's really complicated."

"There is room for improvement for mostly stuff around containers and controlling containers."

"In terms of usability, it has had its challenges. It requires a lot of custom code to integrate into our environment."

"It requires a lot of Windows servers, which we don't like, and the external load balancer configurations, which we also don't like."

"Our customers feel it's very costly."

"The setup is difficult. You need a technical person to help you set it up."

Pricing and Cost Advice

"OpenNebula gives good value for money."

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

"VRA is very expensive but OpenNebula 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."

"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 solution is open source so is free."

"From a budget point of view, the pricing is a bit on the higher side."

"The pricing is very high."

"I'm very interested in the integration with Puppet. However, my organization doesn't have the funding for something like Puppet right now. If VMware would integrate that feature set (Puppet) into vRA. That would be very awesome."

"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."

"We have seen significant ROI. We used to have physical servers, it took 90 days to get a server, order it, buy it, and get it in. We have it down to 10 minutes, building a server with virtualization, and now that's too slow. So, we let the customer do it at their speed. Therefore, it is pretty much up in a couple of minutes and they have a server."

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

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

"The pricing for this solution is roughly 20% lower than the competitive products in the market."
