What is the best way to deploy HDP using virtual machines in a company ? i've been given this task and i don't know much about it. i read APACHE AMBARI INSTALLATION official doc and it sound clear. but it's still mysterious to me which virtual machines and software i should use ? i didn't found a lot of information about it. One of my collegues proposed ceph but it sound inadequat for me because ceph is a storage platform and not a virutal machine managing software. can you help me with that ? Thanks in advance for your help.
