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."It gives us the ability to manage and segregate a guest network with openvSwitch and VLAN IDs."
"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 build your own cloud and make it customizable with APIs."
"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."
"CloudStack is simple to stand up and get off the ground in a hurry. Its centralized design allows for easier troubleshooting when compared to OpenStack. Out of the box, it’s very well suited for white labeling and IaaS."
"Killer features for me were: support for many hypervisors, ability to match business logic, "everything in one box," available APIs."
"CloudStack supports every operating system that supports hypervisors, which makes the product more attractive, compared to vCloud Director or Azure."
"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."
"With a single click, we could set things up and initiate them."
"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."
"OpenNebula has very good integration with SAP Storage."
"The most valuable feature of OpenNebula is that it scales very well."
"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 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."
"It makes maintenance very easy and stress-free for our teams."
"We recognize that CloudStack is an easy-to-use cloud management platform and, in my opinion, there has been a large number of improvements in the past few years, particular when it comes to the modern UI and overall ease of management. However, I believe that CloudStack needs to grow their marketing in the commercial side. They don't have a great piece of market share right now."
"I think that container technology in CloudStack is an area that needs to be improved."
"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."
"Environment is sensitive, so, unlike VMware, you can not afford middle-skilled engineers, they will ruin everything."
"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."
"CS has very descriptive logging, and every time I faced issues and asked for help, I didn’t get any reply from the community. Reason? Its quite obvious. CS runs on specific environments, unique to each case. So, unless it is a functional issue of CS, nobody can help you. All issues were resolved by myself going through logs. This is another reason why you need smart enough people to manage it. Engineers must have knowledge of hypervisors and understand how CS interacts with them."
"I encountered some stability issues. When I tried to remove high-capacity virtual machines it took a long time to update, and sometimes the VM status failed to update properly in the cloud database. This occurred multiple times, even though I had sufficient resources."
"From time to time there is a bug in calculating limits of resources for customer domain/account. Maybe it’s a problem with 4.9.2."
"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."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"They should add more features like object storage."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
