Hello all!!! I have been exploring the cloudstack cloud platform while comparing it with the openstack cloud platform. I am a little skeptical about which solution to use as our cloud platform between cloudstack and OpenStack. Following are the difficulties I am facing which comparing these two solutions. 1.) OpenStack has HEAT as the component for orchestration of application VM's deployed and the cloud setup services as well. Is there any orchestration feature in cloudstack which provides an autscaling feature for the application deployed in it? 2.) OpenStack has TROVE for DBaaS which takes care of the entire lifecycle of the database service which includes deployment, configuration, replication, failover, backup, patching, restores. Is there any similar service in cloudstack for providing DBaaS? 3.) Cloudstack documentation says that it has orchestration feature for its applications, but couldn't find any details regarding the same. Also, for big data Hadoop clusters provisioning, SAHARA component is used in OpenStack. What does this sahara feature provides and is it useful for big data applications? This is feature is not there in cloudstack. What is the importance of serverless functionality feature "Qinling" in openstack which is not there in cloudstack Are there any points of Openstack which completely outshines itself from cloudstack? Thankyou Dhairyasheel Ghadge
