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 API with CloudStack made integration into various external facing web applications simple enough."
"Over the years, we have valued CloudStack for its stability."
"Key features include stability, centralized management design that scales well, and transparent interoperability with different hypervisors and manufacturers.."
"The most valuable feature from my point of view is access to environment via console through separate browser window."
"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."
"CloudStack’s private gateway networking feature is what enables us to offer utmost security and confidentially to our customers and partners, by enabling them to connect to their virtual data centers via dedicated, encrypted, private fiber lines that never touch the public internet space. Ease of setup and management are certainly important additional benefits for us on the engineering team."
"You can manage infrastructure with a few people, since product is monolithic. We had three engineers (storage, virtual, Linux admins) only. Also, CS supports different flavours of hypervisors."
"Killer features for me were: support for many hypervisors, ability to match business logic, "everything in one box," available APIs."
"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."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"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."
"It is quite easy to deploy."
"With a single click, we could set things up and initiate them."
"It makes maintenance very easy and stress-free for our teams."
"The number of contributors to this solution is relatively small compared to other solutions. However, if more frequent users of CloudStack contribute to the open-source community, it will significantly enhance the overall community experience and make it more useful for everyone involved."
"A technology upgrade is one item which could be improved upon a lot."
"For time consuming operations like storage migrations, volume Snapshot restore and the like, we faced issues like MySQL operations timing out and status update failures. Those areas needs improvement."
"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."
"The Windows hosts do not get their hostnames from cloud-init."
"It's really hard to delete zones, clusters, datacenters. You need to follow strict rules, which were not properly documented at the time."
"I think that container technology in CloudStack is an area that needs to be improved."
"The main reason why we started looking for another solution: backups, replication, HA, and dependency on secondary storage. CS is quite sensitive for infrastructure, and any kind of network disruption between CS and secondary storage leads to VM hanging."
"The protocol for clusterization is rough and doesn't work well."
"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 should add more features like object storage."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
