6. Introduction 6  In the cloud computing system we have to address different fundamentals :  virtualization  scalability  interoperability  quality of service (QoS)  cloud delivery models (private, public, hybrid)

7. Evolution 7  Cluster Computing  Distributed Computing  Grid Computing  Utility Computing  Grid Computing

8. Evolution 8  Cluster Computing  Parallel and distributed system  Connects Multiple stand-alone computers into a Single integrated computing resource  Connects through Fast LAN  Used for Load Balancing and High Availability

9. Evolution 9  Distributed Computing  A problem is divided into many tasks, each of which is solved by one computer.  The system has to tolerate failures in individual computers.

10. Evolution 10  Grid Computing  parallel distributed computing  Combination of computer resources from multiple administrative domains  Enables sharing, selection, and aggregation of geographically distributed computers  Connected by a conventional network interface, such as Ethernet

11. Evolution 11

12. Evolution  Utility Computing  Packaging of Computing resources  Provides: Computation, Storage, Services  Charges are base on customers usage  Maximize the efficient use of resources  Minimized associated costs  Examples: Amazon, IBM, Sun Microsystems 12
