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."I liked the separation of the isolated network versus the shared network."
"CloudStack supports every operating system that supports hypervisors, which makes the product more attractive, compared to vCloud Director or Azure."
"The platform is very simple to scale-out."
"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."
"You can use a single API to get things done, rather than multiple APIs on multiple modules."
"CloudStack, by default, gives us a zone-based setup which makes it easier to manage datacenters located in different geographical areas."
"The structuring of the components and isolated environments helped us when using parts of the framework at different levels of product development."
"The API with CloudStack made integration into various external facing web applications simple enough."
"It makes maintenance very easy and stress-free for our teams."
"The most valuable feature of OpenNebula is that it scales very well."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"OpenNebula has very good integration with SAP Storage."
"The service feature appeals most to us, thus it is the most valuable."
"The live migration feature has been great and is something we use very often."
"OpenNebula is lightweight, stable, and easy to customize."
"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."
"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."
"The user can't upload SSH keys from the UI. We have to use the API for this, and it is not always convenient."
"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."
"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."
"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."
"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."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"The storage feature that they have is a bit confusing."
"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."
"There are no payment gateways in OpenNebula."
"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."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"Hosting platforms are limited so the deployment process needs improvement."
