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

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

"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."

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

"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."

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

"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."

"It is quite easy to deploy."

More OpenNebula pros

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

"Other than that, if you put the time learning SaltStack, it is a pretty easy and very powerful tool."

"Being able to give provisioning of environments over to our developers and the different teams has enabled them to put up environments faster and also freed up time for the IT team. This is really one of our bread and butter solutions for our developers."

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

"It's cut our server deployment times down from weeks to an hour."

"He liked the way SaltStack (on the entire cluster) was up and running in a few minutes, and also gave him flexibility to generate traffic, make config changes, etc. on the fly."

"Configuration management: We were using SaltStack for orchestration in liaison with OpenStack."

"It is a highly stable solution."

More VMware Aria Automation pros

Cons

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

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

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

"The storage feature that they have is a bit confusing."

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."

"They should add more features like object storage."

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

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

More OpenNebula cons

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

"I would like to see more out-of-the-box blueprints and workflows for the rest of VMware's products and its portfolio."

"That ServiceNow implementation is a little rough, but those guys in Ohio are doing a great job on it."

"The GUI is clunky and hard to use."

"Probably more stability and just ensuring everything works out-of-the-box. There is still a bit of a gap in terms of product maturity based on all the forums and things that we've seen, so we would like it to be much more mature than what we currently have."

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

"With the workflow aspect, which has manual intervention, a policy needs to be approved by somebody. There could be better management of that piece with better templates. It is like a workflow engine, but does not have enough example templates to do certain things. A lot of people waste a lot of time trying to figure out the same thing, and everybody is trying to figure out the same thing, e.g., how to make a MySQL cluster in a Windows environment?"

"We found some intermittent issues with the Windows minion connection."

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."

"The solution is open source so is free."

"OpenNebula gives good value for money."

"VRA is very expensive but OpenNebula is free."

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

"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."

"I would rate the pricing a ten out of ten, with ten being very expensive."

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

"The solution is free of cost."

"VMware Aria Automation is expensive."

"The solution has helped to increase infrastructure, agility, speed, and provisioning in the time to market."

"The cost of the solution is reasonable for us. Although it is relatively high, we prioritize stability and integration over cost."

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