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.

Quotes from Members

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

Pros

"CloudSphere is very mature and very effective."
"Provides multiple kinds of services for managing the clouds of multiple customers."
"The scalability of the solution is a godsend."
"We do not need to install any appliances or any agents."
"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."
"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."
"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."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"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 freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"It has enabled us to decrease the optics by around 55 to 60%."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
"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."
 

Cons

"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."
"One of the cons of this product is that it will not discover all the applications running."
"There are quite a number of services that can't be deployed using CloudSphere."
"The next feature I would like to have full disclosure of what's being done with the data."
"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 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."
"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 small things that are hard. For example, making sure that it is going to be installable on public clouds."
"The protocol for clusterization is rough and doesn't work well."
"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."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"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."
"I would like to see OpenNebula add more integration with REST API. XML-RPC API is good, but it becomes a pain to form a resting output."
"The storage feature that they have is a bit confusing."
"Hosting platforms are limited so the deployment process needs improvement."
 

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."
"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 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."
"We use the Community Edition, rather than the Enterprise Edition."
"OpenNebula gives good value for money."
