3. Why Cloud Computing?

4. Before Cloud Computing
Let’s take an example, you want to host a website, these are the
following things you would need to do :
Buy a stack of servers.
Keeping the peak traffic in mind, buy more servers.
Monitoring and Maintenance of your servers

5. Disadvantages
This setup is expensive.
Troubleshooting problems can be tedious and may
conflict with your business goals.
Since the traffic is varying, your servers will
be idle most of time.

6. Cloud Computing

7. How it Happens Now?
Put your data on Cloud Servers!
No more buying expensive servers!
Scalability!You server capacity will vary according to traffic.
Your cloud provider will manage your servers,
hence no worries about the underlying infrastructure.

8. What is Cloud Computing?
It is the use of remote servers on the internet to store, manage and
process data rather than a local server or your personal computer
