Cloud computing builds on technologies like service-oriented architecture, grid computing, and virtualization. It offers on-demand, pay-as-you-use computing resources through virtual machines that provide flexibility, reliability, and agility. Virtual machines enable organizations to easily manage computing resources and services through mechanisms like on-demand cloning and live migration. Virtualization has revolutionized data centers and become an essential technology for cloud computing environments by virtualizing computing resources like storage, processing power, memory, and networks.

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
