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."The initial implementation process was quite good."
"Key features include stability, centralized management design that scales well, and transparent interoperability with different hypervisors and manufacturers.."
"We like the virtualization capabilities."
"The structuring of the components and isolated environments helped us when using parts of the framework at different levels of product development."
"The platform is very simple to scale-out."
"Valuable features include that it is a user-friendly portal, VPN P2S and S2S possibilities, and it's easy to manage accounts and limits."
"My company could implement a lot of customizations and integration with load balancers and DNS. When we started using CloudStack, we didn't have that integration, so we developed that. We could fix anything missing in the solution."
"You can use a single API to get things done, rather than multiple APIs on multiple modules."
"The live migration feature has been great and is something we use very often."
"The service feature appeals most to us, thus it is the most valuable."
"It is quite easy to deploy."
"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."
"OpenNebula is lightweight, stable, and easy to customize."
"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."
"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."
"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."
"The user can't upload SSH keys from the UI. We have to use the API for this, and it is not always convenient."
"I think that container technology in CloudStack is an area that needs to be improved."
"Accounts, domains, and user accounts are set up with public cloud in mind, not private."
"It is not widely used so Google does not help very much when you are troubleshooting, and the CloudStack forum is not very active."
"VPN P2S is cutting all connections except the CloudStack environment for the user when he is connected. I would like to have VPN like Cisco's AnyConnect."
"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."
"It's really hard to delete zones, clusters, datacenters. You need to follow strict rules, which were not properly documented at the time."
"Environment is sensitive, so, unlike VMware, you can not afford middle-skilled engineers, they will ruin everything."
"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 front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"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."
"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 protocol for clusterization is rough and doesn't work well."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"There are no payment gateways in OpenNebula."
