This document provides an overview of cloud computing, including its history, types, architecture, characteristics, service models, advantages, and limitations. It discusses how cloud computing allows users to access computing resources over the internet from anywhere. The document outlines the public, private, hybrid, and external cloud types and describes the client, application, platform, and infrastructure layers of cloud computing architecture. It also summarizes the main service models of infrastructure as a service, platform as a service, and software as a service.

 Conclusion

3.  Cloud computing is an Internet ("cloud") based development
and use of computer technology ("computing").
 With Cloud computing users can access database resources via
the Internet from anywhere.

4.  How to Implement cloud computing?
open source software has provided the foundation
for many cloud computing implementations.
The cloud computing environment can consist of
multiple types based on their deployment and usage.
 Types –
1. Public clouds
2. Private clouds
3. Hybrid clouds
4. External clouds

5.  The two most significant components of cloud computing
architecture are known as the front end and the back end. The
front end is the part seen by the client, i.e. the computer user.
 Layers –
Client
Application
Platform
Infrastructure
Server

6.  Application Programming Interface (API)
 Device and location independence
 Cost
 Performance
 Reliability
 Security
 Virtualization
 Maintenance

7.  Cloud computing providers offer their services according to
three fundamental models:
1. infrastructure as a service
(IaaS)
2. platform as a service
(PaaS)
3. software as a service
(SaaS)

8.  Clouds can be classified as:
Infrastructures
Platforms
Applications

9.  Improve flexibility
 Reduce cost
 Unlimited Storage
 Quick Deployment
 Less Control
 Not everything fits into the cloud
 Security in the cloud
 Problem recovery may take more time

10.  After so many years, Cloud Computing today is the beginning of
“network based computing” over Internet in force. It introduces two
totally new computing models, the Client-Cloud computing and the
Terminal-Cloud computing. These new models would create whole
generations of applications and business. It is also the beginning of a
new Internet based service economy.
 In future cloud computing technology will vary rapidly so, this
will be a new change in an internet age.
