Featured Reviews

Muhammad Imran Ali Jan - PeerSpot reviewer
Senior Executive IT Infrastructure at Wateen Telecom (pvt.)
A highly scalable and stable tool that provides good technical support and enables users to manage and optimize resources
The product was handed over to us with pre-installed configurations. We just mounted our server in the rack and enabled the connectivity. The initial setup was quite easy to manage. We are using a private cloud to optimize our hospital management system. We have discussed with the vendor the solution's scalability from private to public cloud for our future needs. All the infrastructure was installed within 15 days.
FOURES Jean-Philippe - PeerSpot reviewer
Products Manager at a tech services company with 501-1,000 employees
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

"The product is helpful for the management, optimization, and utilization of resources."
"We do not need to install any appliances or any agents."
"Provides multiple kinds of services for managing the clouds of multiple customers."
"When I started using CloudSphere, it wasn't mature, and it had multiple issues. For example, my team experienced server issues while using the solution, but recently, I noticed how much CloudSphere has improved. There used to be some latency issues with CloudSphere. It even gave error messages in the past when you select an option such as "the web server is not responding", but it has improved a lot, and now I don't get any errors from CloudSphere. What I like best about CloudSphere is that it has a lot of beneficial features, and it has a single pane for managing multi-cloud environments, which I find very helpful, and it's the main benefit you can get from CloudSphere."
"For the customers I work with, it provides flexibility as far as storage is concerned, so it's security and access."
"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."
"OpenNebula is lightweight, stable, and easy to customize."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula has very good integration with SAP Storage."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"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."
"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."
 

Cons

"The next feature I would like to have full disclosure of what's being done with the data."
"When we start the scanning of, for example, 500 servers, it will not handle the scan. We need to differentiate the jobs - for example, one job for 100 servers, a second job for another 100 servers, et cetera."
"The solution must have a single management console for the resources and VMs."
"There are quite a number of services that can't be deployed using CloudSphere."
"The main issue I experienced from CloudSphere was recently resolved, but an area for improvement in the solution is that it lacks the functionality of migrating resources from one public cloud to another. If CloudSphere could provide that functionality, that would be very beneficial to users and companies."
"They should add more features like object storage."
"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 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."
"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 storage feature that they have is a bit confusing."
"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."
"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."
 

Pricing and Cost Advice

"It depends on how that model will be used. It might be anywhere between $4 and $15 per license per month. It’s less expensive than other options."
"The product is very expensive."
"We use the Community Edition, rather than the Enterprise Edition."
"OpenNebula gives good value for money."
"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."
"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."
