Featured Reviews

Isaac Ogbonnaya - PeerSpot reviewer
Cybersecurity Consultant at Nnamdi Azikiwe University
Attack paths have become visible and cost control is strong but application monitoring still needs work
In my opinion, the best feature of CloudSphere is the attack path analysis, which really helps me to understand how the path works, the misconfigurations, the vulnerabilities, and how they chain together to demonstrate the attack path system. The cost management feature in CloudSphere really helps me so much; it helps me to know the cost visibility, identify the unused resources, eliminate waste, and also helps me in my spending by service across my team and in my overall environment. Using CloudSphere for three years has really helped me tighten my CI/CD pipelines and also my risk-based analytics, understand my attack pathways, the vulnerabilities, and the misconfigurations in my system. CloudSphere's predictive insight really helps me to dictate attack pathway analysis, assisting in mitigating any infrastructure challenges. CloudSphere really helps me with cloud visibility, risk identification, asset discovery, and attack path analysis; they are doing very well in the market right now compared to other software.
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.

Pros

"Provides multiple kinds of services for managing the clouds of multiple customers."
"CloudSphere really helps me with cloud visibility, risk identification, asset discovery, and attack path analysis; they are doing very well in the market right now compared to other software."
"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."
"CloudSphere is very mature and very effective."
"CloudSphere is a good solution that works well and can integrate with multiple clouds and manage all our customers."
"The scalability of the solution is a godsend."
"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."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"It makes maintenance very easy and stress-free for our teams."
"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."
"OpenNebula has very good integration with SAP Storage."
"The most valuable feature of OpenNebula is that it scales very well."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"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 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."
"In terms of areas with room for improvement, I find the management area, the application-focused management area, the end-to-end application visibility, the integration of a direct CI/CD pipeline for developers, and the real-time monitoring and fast response have room for enhancement."
"CloudSphere is not keeping up with the pace of the cloud and there are a number of services that can't be deployed using CloudSphere."
"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."
"The next feature I would like to have full disclosure of what's being done with the data."
"One of the cons of this product is that it will not discover all the applications running."
"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 protocol for clusterization is rough and doesn't work well."
"They should add more features like object storage."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"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 protocol for clusterization is rough and doesn't work well."
"They should add more features like object storage."
"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."
 

Pricing and Cost Advice

"The product is very expensive."
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"The solution is open source so is free."
"OpenNebula gives good value for money."
"VRA is very expensive but OpenNebula 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."
