CloudStack vs Scalr comparison

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

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

"We like the virtualization capabilities."

"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."

"Valuable features include that it is a user-friendly portal, VPN P2S and S2S possibilities, and it's easy to manage accounts and limits."

"We had a relevant reduction of bureaucracy tasks."

"CloudStack is a very feature-rich product; it gives you a lot of control over your VM networks and has extensive integration with storage plugins where you can use many open source tools to bring storage into your CloudStack environment for backups or even to run VMs."

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

"Scalr has helped bring consistency and governance to our workflows, especially at scale, and it is a strong product."

"The product does not have an easily implementable payment gateway."

"The absence of the feature, deploy an instance from a snapshot, is the weak point of the platform. It is a feature that everyone needs nowadays."

"Accounts, domains, and user accounts are set up with public cloud in mind, not private."

"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."

"The installation of CloudStack can be quite challenging because you need a good understanding of the product before starting."

"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."

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

"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."

"Scalr's UI and documentation could be more intuitive, especially for first-time users."

"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."

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

"​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."

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

"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."

"CloudStack is an open-source product."

"The solution is open-source and free."
