I'm very confused to understand what a cloud datacenter actually is.

In my experience, the main services of a data center are the following:

  • Renting rackspace
  • Rack colocation
  • Server locating on rack
  • Server leasing
  • File storage
  • ... etc

Cloud datacenters services are almost same. But what differences are there between them?

"Cloud" is a marketing buzzword without relation to any specific technical aspect. As such, trying to define "cloud" in technical terms will inevitably fail. A "cloud" datacenter is simply a datacenter hosting "cloud" services (whatever that may mean in a specific case).

yeha. and private cloud indicate the hosting your own cloud inside like openstack. public cloud is like you are renting cloud services from third party like Amazon ec2.
