CloudStack vs HPE Eucalyptus [EOL] comparison

"The back-end database design is simple and straight forward. The user interface is designed with external users in mind. Billing is relatively straightforward with this product. Not being restricted to just one hypervisor was nice."

"I liked the separation of the isolated network versus the shared network."

"Multiple types of hypervisor support, multi-zone support, and VPC are great valuable features."

"CloudStack provides an environment that is very simple to use, with built-in APIs and a web interface that supports almost all features of AWS and Azure."

"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."

"CloudStack supports every operating system that supports hypervisors, which makes the product more attractive, compared to vCloud Director or Azure."

"It was easy to deploy, both for PoC and production (with HA)."

"The most valuable feature from my point of view is access to environment via console through separate browser window."

"The most valuable aspect of the solution is the interface on the console."

"I think that container technology in CloudStack is an area that needs to be improved."

"The product could improve by embracing newer technologies like GPU virtualization."

"A technology upgrade is one item which could be improved upon a lot."

"It would be a good to have more specific error messages within administration processes (e.g. problem with creating new instance)."

"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 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."

"The Windows hosts do not get their hostnames from cloud-init."

"Environment is sensitive, so, unlike VMware, you can not afford middle-skilled engineers, they will ruin everything."

"The customization should be improved."

"There is no license, so the product is free unless you are buying professional technical support services."

"The Apache CloudStack is open source, so you do not have licenses to purchase."

"​Give an effort to planning. If possible, contract a specialized consultant company for the initial setup and knowledge transfer.​​"

"The solution is open-source and free."

"CloudStack is an open source solution, so you don't need to pay anything for it. When our company develops something specially for CloudStack, it is donated to the Apache Software Foundation and provided to anyone that wants to use it."

"It is a 100% open-source solution needing just an Apache license. Also, there are no hidden fees to be paid."

"CloudStack is an open-source product."

"As far as I know, CS is still free of charge. If you want to pay some money, Citrix Cloud Platform is based on CS, I think. As for hypervisors – everything as usual, you need to pay for VMware and vCenter. As for XenServer, recently they changed the free feature list, so you may need to pay some money to get useful features like XenMotion."
