CloudStack vs HPE Eucalyptus [EOL] comparison

"We had a relevant reduction of bureaucracy tasks."

"It gives us the ability to manage and segregate a guest network with openvSwitch and VLAN IDs."

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

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

"The API with CloudStack made integration into various external facing web applications simple enough."

"The structuring of the components and isolated environments helped us when using parts of the framework at different levels of product development."

"The platform is very simple to scale-out.​"

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

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

"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."

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

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

"Companies need to be knowledgeable about cloud technology. It's not for novice users."

"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."

"I would like to see support for native VLAN, and fault-tolerance."

"It's really hard to delete zones, clusters, datacenters. You need to follow strict rules, which were not properly documented at the time."

"The customization should be improved."

"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."

"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."

"The solution is open-source and free."

"CloudStack is an open-source product."

"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.​​"

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

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