We performed a comparison between CloudStack and OpenNebula based on real PeerSpot user reviews.
Find out in this report how the two Cloud Management solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."CloudStack is simple to stand up and get off the ground in a hurry. Its centralized design allows for easier troubleshooting when compared to OpenStack. Out of the box, it’s very well suited for white labeling and IaaS."
"The structuring of the components and isolated environments helped us when using parts of the framework at different levels of product development."
"CloudStack helped us showcase our features through process visualization and functional solutions."
"Valuable features include that it is a user-friendly portal, VPN P2S and S2S possibilities, and it's easy to manage accounts and limits."
"It was easy to deploy, both for PoC and production (with HA)."
"Killer features for me were: support for many hypervisors, ability to match business logic, "everything in one box," available APIs."
"It is very easy to install and manage. It has the all modules in one node, unlike other software (OpenStack). The product allows a customized look and feel, and the ability to add custom workflows."
"You can build your own cloud and make it customizable with APIs."
"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."
"It makes maintenance very easy and stress-free for our teams."
"OpenNebula is lightweight, stable, and easy to customize."
"The live migration feature has been great and is something we use very often."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"It is quite easy to deploy."
"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 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."
"My teammates have complained about the upgrade. The source code had massive files that had to be merged with our own development to upgrade to the latest version of CloudStack. It was quite painful for them. CloudStack could add some cost management tools to give me some control over the costs associated with the number of users of my services."
"I would like to see support for native VLAN, and fault-tolerance."
"There are some minor things that can be improved even more such as, perhaps, a bit more polishing on the GUI side to catch up with the API possibilities (which are really extensive) but otherwise nothing critical."
"We did encounter issues with stability, and the main issue was secondary storage. When it is not available, XenServers and hypervisors are affected. And CS doesn’t do anything to reboot, or fix. Come to think of it, maybe it shouldn’t, considering their approach – CS just orchestrates everything else on the hypervisor and storage level."
"This product needs a lot improvement on the development side. Every new version introduces new bugs. It lacks many features needed for NFV like DPDK, SR-IOV support, etc."
"I think that container technology in CloudStack is an area that needs to be improved."
"CS has very descriptive logging, and every time I faced issues and asked for help, I didn’t get any reply from the community. Reason? Its quite obvious. CS runs on specific environments, unique to each case. So, unless it is a functional issue of CS, nobody can help you. All issues were resolved by myself going through logs. This is another reason why you need smart enough people to manage it. Engineers must have knowledge of hypervisors and understand how CS interacts with them."
"I encountered some stability issues. When I tried to remove high-capacity virtual machines it took a long time to update, and sometimes the VM status failed to update properly in the cloud database. This occurred multiple times, even though I had sufficient resources."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"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."
"There are no payment gateways in OpenNebula."
"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 protocol for clusterization is rough and doesn't work well."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"The UI, monitoring, and alerting could benefit from further improvements."
