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."My company could implement a lot of customizations and integration with load balancers and DNS. When we started using CloudStack, we didn't have that integration, so we developed that. We could fix anything missing in the solution."
"The initial implementation process was quite good."
"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."
"It is very easy to install and manage. It has the all modules in one node, unlike other software (OpenStack). The product allows a customized look and feel, and the ability to add custom workflows."
"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."
"CloudStack, by default, gives us a zone-based setup which makes it easier to manage datacenters located in different geographical areas."
"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."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"The service feature appeals most to us, thus it is the most valuable."
"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."
"OpenNebula is lightweight, stable, and easy to customize."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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."
"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."
"It's really hard to delete zones, clusters, datacenters. You need to follow strict rules, which were not properly documented at the time."
"I would like to see support for native VLAN, and fault-tolerance."
"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 area of Apache CloudStack that could stand the most improvement is the functionality/features around the virtual routers. They can be somewhat cumbersome to deal with at times and are the least stable piece of the product."
"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."
"The protocol for clusterization is rough and doesn't work well."
"The storage feature that they have is a bit confusing."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"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."
"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."
