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."Over the years, we have valued CloudStack for its stability."
"It gives us the ability to manage and segregate a guest network with openvSwitch and VLAN IDs."
"We like the virtualization capabilities."
"You can use a single API to get things done, rather than multiple APIs on multiple modules."
"When compared to OpenStack, CloudStack is also an open-source platform that is continuously improving its features and capabilities with each new version release. Having worked with CloudStack 4.7, 4.14, and most recently, 4.17, I have noticed significant enhancements in the platform's features and customer experience, such as the introduction of a new user interface in the latest release. Notably, the latest versions have made major improvements to VM live migrations, making them more efficient and effective."
"It has become easy to deploy new devices with no or minimal hardware changes. Now, a user can be ready to use a firewall within a few minutes, as compared to the traditional physical model which involved purchase, shipping, hardware configuration, cabling, power, etc."
"The back-end database design is simple and straight forward. The user interface is designed with external users in mind. Billing is relatively straightforward with this product. Not being restricted to just one hypervisor was nice."
"The platform is very simple to scale-out."
"With a single click, we could set things up and initiate them."
"OpenNebula is lightweight, stable, and easy to customize."
"It makes maintenance very easy and stress-free for our teams."
"The most valuable feature of OpenNebula is that it scales very well."
"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 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."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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."
"The Windows hosts do not get their hostnames from cloud-init."
"Environment is sensitive, so, unlike VMware, you can not afford middle-skilled engineers, they will ruin everything."
"Accounts, domains, and user accounts are set up with public cloud in mind, not private."
"A technology upgrade is one item which could be improved upon a lot."
"It would be great to have a couple of “external” networks for VPC and have the possibility, for each domain, to choose they type of “external” network."
"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."
"The area of improvement could be the regionalization aspect. For example, managing multiple regions or HubStack deployments together was not thought out thoroughly in the versions I used. We faced issues around managing the global infrastructure and had to develop around it."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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."
"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."
"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."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
