4. THE TRADITIONAL SERVER CONCEPT
• SYSTEM ADMINISTRATORS OFTEN TALK ABOUT SERVERS
AS A WHOLE UNIT THAT INCLUDES THE HARDWARE, THE
OS, THE STORAGE, AND THE APPLICATIONS.
• SERVERS ARE OFTEN REFERRED TO BY THEIR FUNCTION
I.E. THE EXCHANGE SERVER, THE SQL SERVER, THE FILE
SERVER, ETC.
• IF THE FILE SERVER FILLS UP, OR THE EXCHANGE SERVER
BECOMES OVERTAXED, THEN THE SYSTEM
ADMINISTRATORS MUST ADD IN A NEW SERVER.

5. THE TRADITIONAL SERVER CONCEPT
• Unless there are multiple servers, if a service
experiences a hardware failure, then the
service is down.
• System Admins can implement clusters of
servers to make them more fault tolerant.
However, even clusters have limits on their
scalability, and not all applications work in a
clustered environment.

8. CLOUD COMPUTING

9. DEFINITION
CLOUD COMPUTING is the delivery of
computing as a service rather than a product,
whereby shared resources software and
information are provided to the computers
and other devices over a network.
Cloud is a large group of interconnected
computers
Cloud here is actually a metaphor of internet

11. Cloud computing architecture
*. Cloud computing can be divided into two sections
1. Front end
2. back end
*. Front end includes client computers
*. Back end is the cloud section of the system
*. The administrator uses a set of rules called protocols
and uses special kind of softwares called middleware for
smooth running and traffic control
*. Middleware allows networked computers to
communicate with each other.

12. CLOUD COMPUTING ARCHITECTURE

13. CLOUD COMPUTING SERVICES
Cloud computing providers offer their services
according to three fundamental models
• Infrastructure as a service (IaaS)
• platform as a service (PaaS)
• software as a service (SaaS)

14. CLOUD COMPUTING SERVICES

15. CLOUD COMPUTING SERVICES
IAAS- In this most basic cloud service model, cloud providers offer
computers – as physical or more often as virtual machines –, raw
(block) storage, firewalls, load balancers, and networks. Cloud
providers typically bill IaaS services on a utility computing basis
PAAS- In the PaaS model cloud providers deliver a computing
platform and/or solution stack typically including operating system,
programming language execution environment, database, and web
server.
SAAS- In this model, cloud providers install and operate application
software in the cloud and cloud users access the software from
cloud clients.

16. CLOUD COMPUTING SERVICES

18. ADVANTAGES
1.Access you data all the times
2.A physical storage centre is no longer needed
3.Most have a pay structure that only calls for payment when used
4.Relieves burden on IT proffesssional and frees up their time in office
5.Easily scalable so companies can add or substract resources based on their own needs
DISADVANTAGES
1.Less control comes with handling over your data and information
2.Dependence on a third party to ensure security and confidentiality of data and information
3.Long term dependence on cloud host or maintainance o your information

19. ADVANTAGES AND DISADVANTAGES

20. APPLICATIONS

22. Conclusion
Thus cloud computing provide a super-computing
power .This cloud of computers extends beyond a single
company or enterprise.
The applications and data served by the cloud are
available to broad group of users, cross-enterprise and cross-
platform.
