hosting or computing provider and then resells them to its own customers.
Cloud Migration ✔✔The process of transitioning all or part of a company's data, applications,
and services from onsite premises to the cloud, where the information can be provided over the
Internet on an on-demand basis.
Cloud OS ✔✔A phrase frequently used in place of PaaS to denote an association to cloud

Trusted Cloud Initiative (TCI) Reference Model ✔✔A guide for cloud providers, allowing them to
create a holistic architecture (including the physical facility of the datacenter, the logical layout
of the network, and the processes necessary to utilize both) that cloud customers can purchase
and use with comfort and confidence.
Characteristics of Cloud Computing ✔✔· Broad network access
· Resource pooling
· Measured service
· On demand self-service
