Cloud computing isn't one-size-fits-all. There are three main models that offer different levels of control and management.
1Infrastructure as a Service (IaaS)
IaaS contains the basic building blocks for cloud IT and typically provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. It provides you with the highest level of flexibility and management control over your IT resources.
2Platform as a Service (PaaS)
PaaS removes the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allows you to focus on the deployment and management of your applications.
