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 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."
"Key features include stability, centralized management design that scales well, and transparent interoperability with different hypervisors and manufacturers.."
"The API with CloudStack made integration into various external facing web applications simple enough."
"The platform is very simple to scale-out."
"The product gives us the ability to orchestrate large virtual environments and is flexible enough to allow us to configure it for what we need. We value the flexibility of the networking feature set as well as the ability to build virtual private clouds."
"Multiple types of hypervisor support, multi-zone support, and VPC are great valuable features."
"We had a relevant reduction of bureaucracy tasks."
"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."
"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."
"OpenNebula has very good integration with SAP Storage."
"It makes maintenance very easy and stress-free for our teams."
"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."
"The most valuable feature of OpenNebula is that it scales very well."
"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."
"The numerous, multi-layered drill-down menus make it difficult to find one simple knob to turn."
"Environment is sensitive, so, unlike VMware, you can not afford middle-skilled engineers, they will ruin everything."
"Lack of support for third-party software vendors such as Veeam and Zerto creates limitations on comprehensive offerings which would include backup and disaster recovery."
"I think that container technology in CloudStack is an area that needs to be improved."
"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 user can't upload SSH keys from the UI. We have to use the API for this, and it is not always convenient."
"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."
"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 front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"There are no payment gateways 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."
"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."
"The storage feature that they have is a bit confusing."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
