AB
CTO at Encha
A highly scalable solution that gives good value for money, but it does not have payment gateways
OpenNebula's templates are weak, and it could do something to make template creation a lot easier to use. The solution has a template for every single VM you create, which is not clever. You should be able to use a template for many different virtual machines. There are no payment gateways in OpenNebula.
VasilisGiannitsiotis - PeerSpot reviewer
Senior IT at ITSolutions
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 most valuable feature of OpenNebula is that it scales very well."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"The service feature appeals most to us, thus it is the most valuable."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"With a single click, we could set things up and initiate them."
"The live migration feature has been great and is something we use very often."
"It is quite easy to deploy."
"We have it deployed in a highly-available environment and scalability is nice because we just had another ESX host and then we are able to increase the capacity."
"vRealize automation stability is pretty good. They are always fixing bugs. The product team is doing a great job of addressing any issues that we might have."
"The infrastructure has helped us to greatly increase our agility."
"Using this solution has greatly reduced the time it takes to deploy a server; it used to take at least one month, whereas now, to deploy a server takes two hours."
"We provided the ability to request virtual machines to our end users. Before, this was a very manual process, which took engineers to do. Now, it's an automated process."
"Reactors, because of the automation help they provide (reacting to custom events)."
"I like that it is easy to deploy the infrastructure."
"Interoperability between operating systems with the ability to perform mass automation with triggering Integration with many vendors These features are valuable because I need them to complete the work assigned to me."
 

Cons

"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."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"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."
"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."
"There are no payment gateways 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 could extend the ability to use vRealize Orchestrator Automation for organizations with multiple tenants. It should be easier to operate and extend different capabilities from vRealize Orchestrator. Currently, it's difficult to build advanced services in Aria Automation because you need to use the vRealize Orchestrator."
"Implementation directly with our SRM product, because we know what the other products are out there that VM is offering, such as Site Recovery Manager (SRM). There are ties which you can customize to put them into that, but it would be nice if it came as an out-of-the-box feature."
"The setup is difficult. You need a technical person to help you set it up."
"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."
"There is some performance lag, but that could be on our end."
"It is not super-intuitive. It does require some skills to understand how to use it. I had no problem, but I had spent a lot of time already learning this product ahead of moving it to an operational status. But as we did so, we had a hard time bringing some people from other groups into the fold, to script and work against this environment. So, the ability to build workflows within that automation needs to be streamlined."
"They should make it a little bit more dynamic, a little bit easier to deal with large-scale AD deployments. They need to make it a little more enterprise-ready. That is the one thing that kills us."
"There are a lot of improvements required with regards to vRealize Automation."
 

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."
"VRA is very expensive but OpenNebula is free."
"OpenNebula gives good value for money."
"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."
"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."
"The solution is pretty expensive but provides good workload management."
"It is pricey for what you get."
"The pricing is very high."
"SaltStack is an open-source product."
"VMware Aria Automation is expensive."
