Cloud computing allows users to access applications and files from any device with internet access. It stores and maintains data and applications on remote servers that users can access through the internet rather than local hardware. The concept of cloud computing was first suggested in 1961 as computing sold as a utility. Major companies like Amazon, Google, and Microsoft now offer cloud computing services across various models including SaaS, PaaS, IaaS, public, private and hybrid clouds. Cloud computing provides advantages like cost savings, flexibility, mobility and scalability but also poses risks such as downtime, security issues and bandwidth constraints.

3. What is Cloud Computing?
Cloud computing is a technology that uses the internet and
central remote servers to maintain data and applications.
Cloud computing allows consumers and businesses to use
applications without installation and access their personal
files at any computer with internet access.
User do not have or need knowledge, control, ownership in
the computer infrastructure.
A simple example of cloud computing is Yahoo email or
Gmail etc.

4. History of Cloud Computing :
At around in 1961, John MacCharty suggested in a speech at MIT that
computing can be sold like a utility, just like a water or electricity.
In 1999, Salesforce.com started delivering of applications to users using
a simple website. The applications were delivered to enterprises over the
Internet, and this way the dream of computing sold as utility were true.
In 2002, Amazon started Amazon Web Services, providing services like
storage, computation and even human intelligence.

5. In 2009, Google Apps also started to provide cloud computing
enterprise applications.
In 2009, Microsoft launched Windows Azure, and companies like
Oracle and HP have all joined the game. This proves that today,
cloud computing has become mainstream.

6. Components of Cloud Computing :
There are three basic components of cloud computing :
Client computers : Clients are the device that the end user interact
with cloud.
Distributed Servers : Often servers are in geographically different
places, but server acts as if they are working
next to each other.
Data Centers : It is collection of servers where application is placed
and is accessed via internet.

7. Service Model :

8. SaaS(Software as a service): Required software, Operating
system & network is provided.
PaaS(Platform as service): Operating system and network is
provided
IaaS(Infrastructure as a service): Just Network is provided
Service Model :

9. Application of Cloud Computing :
Social Networking sites.
E-mail sites.
Search Engines.
Many more services OVER THE
INTERNET.

10. Types of Cloud Computing :
Public cloud
Private cloud
Hybrid cloud

11. Advantages of Cloud Computing :
Cost Savings
Reliability
Flexible capacity
Improved mobility
Do more with less
No hardware required

12. Disadvantages of Cloud Computing :
Possible Downtime
Security Issues
Require High Speed Internet connection
No Redundancy
Bandwidth issue
