The document presents an overview of cloud computing and its security, discussing the cloud as a global network for data management and services delivery. It outlines five essential characteristics of cloud computing along with four deployment models and three service models. The key features include on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

2. WHAT IS CLOUD?
The cloud is a global network of servers
that store and manage data, run
applications, and deliver content and
services over the internet.

3. History of Cloud Computing

4. "cloud" definition is composed
of:
 5 essential characteristics
 4 deployment models
 3 service models

5. 5 Essential Characteristics

6. On-Demand Self-Service
A consumer can unilaterally provision the cloud, such as server time
and network storage, as needed automatically without requiring
assistance form the Cloud Service Provider (CSP).
Broad Network Access
The cloud is available over the network and accessed through
standard devices (e.g., mobile phones, tablets, laptops, and
workstations).
Resource Pooling
The cloud is pooled or shared to serve multiple consumers, with
different physical and virtual resources dynamically assigned and
reassigned according to consumer demand.

7. Rapid Elasticity
The cloud can be elastically provisioned
and released, in some cases automatically,
to scale rapidly outward and inward based
on demand.
Measured Service
pay for only what you use
