Apache CloudStack vs. Virtuozzo Application Platform

CloudStack is well suited if you want to keep the costs low and still need a reliable and robust tool to cloud virtualization orchestration. The end user interface is friendly so users can find and use functionalities quickly. Also, the newer version allows you to integrate CloudStack with external authentication using SAML for single sign-on. It can be less appropriate for an administrator that does not want to do a lot of interventions using a command line or that does not use the Linux operating system.

In case you want a cheaper PaaS that may be available in your country (Brazil, in my case), you may give Jelastic a try. There are some other strong competitors for the PaaS scenario with free versions, but the paid versions are far more expensive.

• SSH is still tricky to use. You have to log in to a gateway and go to an option menu to get logged in. Sometimes it was not available or too slow.
• Some errors are not clear enough. It took some time to understand which files I had to upload to get my custom SSL certificates working.

The University, my first large implementation, had a big issue with 149 small data centers spread on São Paulo State, this data centers costs to university were very high, the consolidation idea in two data centers were awesome, but were worried with the management, so we adopted ACS to management of all 576 physical hosts. Now a days the university is delivering IaaS for all staff, students, teachers and researchers, they are using these resources to delivery services to their clients and have a great results in research area

The price of Jelastic for the paid version (considering SSL) is better.

• Minimal impact at migration from the earlier solution used (Citrix CloudPortal), once both solutions have a common kernel.
• Reduction to 0 with payment of software license.
