CloudKitty : the Open Source cloud rating component

Companies expect that migration to cloud will downsize their infrastructure costs.


Is it a reality ?


  • Are you able today to real-time follow your private cloud costs, as virtual machines launch and stop?
  • Do end-users understand these stakes and do they adopt good practices in their cloud usage?
  • How can you better follow and control these costs ?


These were the central questions that aimed us to launch CloudKitty, the first and only full-Open Source tool enabling rating and chargeback for clouds.
