What is Cloud Computing?
Model for enabling ubiquitous, convenient , on-demand network
access
A shared pool of configurable computing resources
(e.g., networks, servers, storage, applications, and services)
Rapidly provisioned and released with minimal management
Effort or service provider interaction.
 This cloud model is composed of
1.Five essential characteristics
2.three service models
3.four deployment models.

Cloud Computing Service Layers
Description
Services – Complete business services such as PayPal, OpenID,
OAuth, Google Maps, Alexa
Services
Application
Focused
Infrastructure
Focused
Application – Cloud based software that eliminates the need
for local installation such as Google Apps, Microsoft Online
Storage – Data storage or cloud based NAS such as CTERA,
iDisk, CloudNAS
Development – Software development platforms used to
build custom cloud based applications (PAAS & SAAS) such as
SalesForce
Platform – Cloud based platforms, typically provided using
virtualization, such as Amazon ECC, Sun Grid
Hosting – Physical data centers such as those run by IBM, HP,
NaviSite, etc.

Virtualization
• Virtual workspaces:
– An abstraction of an execution environment that can be made
dynamically available to authorized clients by using well-defined
protocols,
– Resource quota (e.g. CPU, memory share),
– Software configuration (e.g. O/S, provided services).
• Implement on Virtual Machines (VMs):
– Abstraction of a physical host machine,
– Hypervisor intercepts and emulates instructions from VMs, and allows
management of VMs,
– VMWare, Xen, etc.
• Provide infrastructure API:
– Plug-ins to hardware/support structures Hardware

Virtual Machines
• VM technology allows multiple virtual
machines to run on a single physical machine.

etc.
Performance: Para-virtualization (e.g. Xen) is very close to raw physical performance!

11.
What is the purpose and benefits?
• infrastructure-less.
• “pay as used and on demand”, all of us can save in
capital and operational investment!
• Clients can:
– Put their data on the platform instead of on their own
desktop PCs and/or on their own servers.
– They can put their applications on the cloud and use the
servers within the cloud to do processing and data
manipulations etc.
11

12.
Cloud-Sourcing
• Why is it becoming a Big Deal:
– Using high-scale/low-cost providers,
– Any time/place access via web browser,
– Rapid scalability; incremental cost and load sharing,
– Can forget need to focus on local IT.
• Concerns:
– Performance, reliability, and SLAs,
– Control of data, and service parameters,
– Application features and choices,
– Interaction between Cloud providers,
– No standard API – mix of SOAP and REST!
– Privacy, security, compliance, trust…

13.
Cloud Storage
• Several large Web companies are now exploiting the
fact that they have data storage capacity that can be
hired out to others.
– allows data stored remotely to be temporarily cached on
desktop computers, mobile phones or other Internet-
linked devices.
• Amazon’s Elastic Compute Cloud (EC2) and Simple
Storage Solution (S3) are well known examples
– Mechanical Turk
13

14.
Utility Computing – EC2
• Amazon Elastic Compute Cloud (EC2):
– Elastic, marshal 1 to 100+ PCs via WS,
– Machine Specs…,
– Fairly cheap!
• Powered by Xen – a Virtual Machine:
– Different from Vmware and VPC as uses “para-virtualization” where
the guest OS is modified to use special hyper-calls:
– Hardware contributions by Intel (VT-x/Vanderpool) and AMD (AMD-V).
– Supports “Live Migration” of a virtual machine between hosts.
• Linux, Windows, OpenSolaris
• Management Console/AP

The Future
• Many of the activities loosely grouped together under cloud
computing have already been happening and centralised
computing activity is not a new phenomena
• Grid Computing was the last research-led centralised
approach
• However there are concerns that the mainstream adoption of
cloud computing could cause many problems for users
• Many new open source systems appearing that you can install
and run on your local cluster
– should be able to run a variety of applications on these systems
