WHAT ARE CLOUDS? Clouds are “Virtual Clusters” Clouds support access of(lease of) computer instances
Instances accept data and job descriptions (code) and return results that are data and status flags
The datacenter with hardware and software is what we will call a Cloud.

WHAT IS CLOUD COMPUTING
“A computing cloud is a set of network enable services providing scalable, QoS guaranteed, normally personalized, inexpensive computing infrastructures on demand, which could be accessed in a simple and pervasive way.”

VIRTUALIZATION TECHNOLOGY
Virtual machine is a software implementation of a real machine
Full virtualizationInstead of 100 physical servers ,we can now have 100 virtual server images running on 1 physical server, this reduces the used infrastructure
Platform virtualization Application virtualization
Virtual appliances
Significance : Server consolidation Virtual memory

•Virtual machine images can be easily updated and redeployed•If any physical server fails then the virtual machines that it was hosting are simply restarted on different physical server

CISCO: EVOLVING INTEROPERABILITY
Cisco adopted Web 2.0-based collaboration products. Interoperability across cloud infrastructures—that is, the
intercloud In place of stand alone clouds , enterprise clouds with
enhanced security and full interoperability needs to be developed which remains a challenge
