2.  CC is an emerging research infrastructure
that builds on the achievements of different
research areas
• SOA (service oriented architecture)
• Grid computing
• Virtualization technology
• It offers infrastructure as a service – pay as you use
and on demand computing
• IAAS model in public and private cloud. These service
named as a virtual machine provisioning and migration
services.
• Historically we can install a new server certain work
load to particular services for client put lot of effort

3. VM is very flexible and easy to manage in
different loads
VM enables high teliable and agile
deployment mechanism
• Management of services
• Ondemand cloning
• Live migration

4. It has revolutionized data center’s tech
It has become an essential and enabling
technology of cloud computing
environment
Virtualization can be defined 4 computing
resources.
• Storage, processing power, memory and network.

5.  VM technology makes it very flexible and ease to
manage resources
 It enable high, reliable and agile deployment
mechanism and management of services,
providing on demand cloning and live migration
Public Cloud & Infrastructure services
• It is a external cloud and also a traditional mainstream
• Examples : Amazon E2C, GoGrid, accelerator,
rackspace
• Amazon E2C reduce the time required and booting a
new server’s instance to minutes
• Amazon offers different instances
• Resource needs(small, large and xl)
• High CPU, memory

6.  It aims at providing public cloud functionality
but org data and resources to meet security
and governance requirement.
 It exhibits a highly virtualized clod data center
locate inside an org firewall.
 Characterisitics
• Allow service provisioning and compute capability for
an org user in a self service manner
• Automate and provide well managed virtualized
environment.
• Optimize computing resources and servers utilization
• Support specific workloads.
Eg: Eucalyptus and open nebula

7.  Vm has their own challenges and complexities
 Commercial, open source products and research projects
such as open nebula, IBM virtualisationVMware.
 It also used in scientific and commercial infrastructure
like Globus VWS, Eucalyptus and Amazon
 It refers to the ability of users community to access the
system- whether for submitting new work, upodating or
altering the exisiting work or collecting the resultsof the
previous work
 The service should be available all time along with some
planned /unplanned downtime according to certain SLA
High availability

8.  It is very important virtualization management
vendors
 The machine produced by each one of them
 Dell, HP IBM microsoft, xensource and
vmware
 This group is dedicated for delivering an API
specification for the remote management of
cloud computings

10. 1. Select a server from a pool of available
servers along with the appropriate OS
template you need provision the virtual
machine.
2. Load the appropriate s/w
3. Customize and configure the machine to
configure an associated n/w and storage
resources.
4. Finally vm server is ready to start with its
newly loaded s/w
