Amit Kantia - PeerSpot reviewer
Its most valuable feature is the ability to capture attributes in the console, but it is not a stable solution
I recommend others to use Densify. They can not only use it for reporting but for automation as well. They can implement the policies on the console easily during the build-out procedure. Stability is the primary concern to us as it is causing lots of problems. We can only make significant decisions if Densify allows us, and it takes lots of time. Thus, I rate the tool as a six out of ten.
FOURES Jean-Philippe - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"Densify's ability to aggregate multiple on-premise vCenters and multiple cloud accounts, gives it a level of visibility not found in many places."
"The Control Console provides a very easy to read dashboard of "too little/just right/too much" resources both for current data and on a historical or predictive basis."
"The solution's tech support is excellent."
"The tool will come back and tell us that we can operate with 1,000 minutes as an example, save 90% on the contractual rate and not run into any issues."
"The Control Console is an incredible way to give a quick view of current capacity utilization allowing technical people to drill down quickly and allowing business/management people to get a quick overview of the environment."
"I would say that the initial thing is that it provides us with a technological basis to expand capacity management beyond Excel."
"The Densify Control Console, and Environment Status."
"One would be the automatic rebalancing of the environment. That was one feature which helped. With that, we could improve our efficiency of our VMware infrastructure."
"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 solution provides templates for configurations that can easily be exchanged to VMs."
"It makes maintenance very easy and stress-free for our teams."
"With a single click, we could set things up and initiate them."
"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 live migration feature has been great and is something we use very often."
"The most valuable feature of OpenNebula is that it scales very well."
 

Cons

"In terms of integration, the tool has great data. However, it's not always meaningful because the true business attributes of how most Fortune 500 companies operate are not maintaining in one tool, they're in a school of many tools."
"A closer integration to the service management processes."
"Normalization of CPU utilization is required. At present, the data is available based on entitlement level."
"Unfortunately the tools and mechanisms which really came to maturity in the cloud, and were not mainstream on-premise, are still not implemented."
"Initially we talked about some custom reporting, wherein our customer expected certain reports on a few areas, like how the storage is allocated, how the network performance is doing, and how the network utilization is happening for a virtual machine."
"Some parts of the interface are rather complex and require a bit of time to navigate, but this has never stopped us as a Densify advisor is readily available to help with our "how to" queries."
"The solution's stability is the primary concern for me."
"It seems that the mechanism for integration is, it goes so far but I think there could be some standard integration to normal remedy service now etc. I think that should be out of the box."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"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."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"There are no payment gateways in OpenNebula."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"The protocol for clusterization is rough and doesn't work well."
 

Pricing and Cost Advice

"Densify has licensing setup so you can collect data without licensing. It gives you the ability to collect on everything, then choose later what you would like to license."
"Cost is always involved, but then I feel that this solution is better than other products that we have."
"There was some sticker shock, as this is not just another software product to spit out graphs."
"Setup cost is negligible, as it scales fairly well."
"OpenNebula gives good value for money."
"The solution is open source so 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."
"VRA is very expensive but OpenNebula is free."
"We use the Community Edition, rather than the Enterprise Edition."

What do you like most about OpenNebula?
The live migration feature has been great and is something we use very often.
What needs improvement with OpenNebula?
The web interface could be better. It's not very difficult to use, but there's room for enhancement. Another area for improvement is the integration with hardware to manage the lower layer of the n...
