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

PARALLELIZATION AND VIRTUALIZATION

DATA-INTENSIVE PROCESSING

•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

RELATED WORKS AND RESULTS

Microsoft: Software plus Services

IBM: Transformation through Customer Implementations

Cisco: Evolving Interoperability

MICROSOFT: SOFTWARE PLUS SERVICES

Windows Azure Services Platform.

The Azure platform is hosted in Microsoft data centers.

It facilitates: Development of applications Improved Service management Improved Service-hosting

Several Microsoft SaaS applications already run on the Azure platform

IBM: TRANSFORMATION THROUGH CUSTOMERIMPLEMENTATIONS

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
