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

"It has enabled us to decrease the optics by around 55 to 60%."

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

"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."

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

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

"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."

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

More OpenNebula pros

"It is probably 90 percent quicker to get something out the door than it was before. For developers, depending on who is building VMs for them, sometimes they request anywhere from 20 to 100. Now, we can deploy them in a matter of an hour, where previously it might have taken me three days to deploy out 100 VMs."

"We can take a template, spin it up, revise it, save it back off, and be able to have that for other departments, so we can deploy things very quickly and easily instead of manually building systems that would take several hours or a day."

"One of the valuable features is controlling VM standards and server sprawl while at the same time providing the ability for end users to self-provision VMs."

"In terms of recovery, it takes only a tenth of the time that's required compared to a human element."

"We like vRA because it helps make systems available on time for our customers, on demand."

"From day 1 that it went into production, we started seeing its benefits."

"value; It does a lot of things automatically that would take our group, when we're already strapped for time, a lot of time to go through and clean stuff out of databases and the like."

"What I like the most about vRA: Its seamless ability for users to be able to go pick a catalog item that we have created for them, while they are testing a new version of their code and say, "Okay, I want you to make my old version (based on these blueprints) run, please deploy me - my entire environment.""

More VMware Aria Automation pros

Cons

"They should add more features like object storage."

"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."

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

"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."

"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."

More OpenNebula cons

"I have not found this solution to be user-friendly. It's really complicated. The demo shows that you can automate anything but they only show basic scenarios. If you want to do anything more complicated than that, it becomes very complicated to set up."

"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?"

"The infrastructure part and VM reconfigure need improvement so that the end user can smoothly perform all the tasks which they are directly performing on the endpoints."

"When it comes to the orchestration workflow, you're on your own. The documentation and resources are very limited, and you have to learn everything on your own."

"It has some limitations for scalability, especially for remote data center management. For some components, everything need to be centralized."

"The most important thing that we missed in vRanger was the possibility to mount several images instantaneously and present it so we can run it immediately."

"There are a number of bugs and regression errors that can make it frustrating at times, but given the flexibility so far I have found adequate workarounds."

"The back-end has a steep learning curve."

Pricing and Cost Advice

"The solution is open source so is free."

"OpenNebula gives good value for money."

"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."

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

"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."

"VRA is very expensive but OpenNebula is free."

"VMware Aria Automation is expensive."

"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."

"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."

"SaltStack is an open-source product."

"This is an expensive product and the high price is starting to become an issue for us."

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