*My short list of requirement is:* - Legacy Stateful Application on my VMs - No time to change the application code base(to convert them as stateless apps which are work better on openstack) - Completely opensource solution(HA in openstack need "stratus allways on cloud" solution or something like that, which are not opensource) - High amount of code stability - Enterprise proven solution - Better siute for private cloud instead of public - High amount of HA, fault tolerance, resiliency in underlying layers *By the aim of these requirement description, what about the decision between OpenStack & CloudStack?*
