Objective

To provide a general overview of cloud

computing including:

How could affect my future business Is the cloud for me and my business

What are some of the issues I should

consider

Why should this be important to me

Origin of the term Cloud Computing

Comes from the early days of the Internetwhere we drew the network as a cloud we

didnt care where the messages went the cloud

hid it from us Kevin Marks, Google

First cloud around networking (TCP/IPabstraction)

Second cloud around documents (WWW data

abstraction)

The emerging cloud combines the infrastructure

complexities of servers, applications, data, and

heterogeneous platforms

Summarized History

1960 - John McCarthy opined that "computation may someday beorganized as a public utility"

Early 1990s The term cloud comes into commercial use referringto large networks and the advancement of the Internet.

1999 Salesforce.com is established, providing an

on demandSaaS (Software as a Service).

2001 IBM details the SaaS concept in their Autonomic ComputingManifesto

2005 Amazon provides access to their excess capacity on a utilitycomputing and storage basis

2007 Google, IBM, various Universities embark on a large scalecloud computing research project

2008 Gartner says cloud computing will shape the relationshipamong consumers of IT services, those who use IT services andthose who sell them

Definition

Lots of confusion

Several different loosely applied definitions

a style of computing in which massivelyscalable IT-related capabilities are provided

"as a service" using Internet technologies to

multiple external customers

November 18, 2009 6


7/21

Definition Continued

an internal or external cloud enabled service

offering

the provision of dynamically scalable and

often virtualized resources as a service over

the Internet.

a general term for anything that involves

delivering hosted services over the Internet.

Cloud computing is a model for enabling convenient,on-demand network access to a shared pool ofconfigurable computing resources (e.g., networks,

servers, storage, applications, and services) that canbe rapidly provisioned and released with minimalmanagement effort or service provider interaction.(NIST Definition, National Institute of Standards and Technology)

This cloud model promotes availability and is composed of

five essential characteristics, three service models, and fourdeployment models.

5 Essential Cloud Characteristics

On-demand self-service

Broad network access (Internet)

Resource pooling Location independence

Rapid elasticity

Measured service

November 18, 2009 9


10/21

Cloud computing often leverages:

Massive and Rapid scalability

Homogeneity

Virtualization

Resilient computing

Low cost software

Geographic distribution, (many datacenters)

Service orientation

Advanced security technologies

Additional Cloud Characteristics

11/21

Private Cloud (a.k.a. Internal Cloud)

enterprise owned or leased

Community Cloud (a.k.a. External Cloud) shared infrastructure for specific community

Public cloud (a.k.a. External Cloud)

Sold to the public, mega-scale infrastructure Hybrid cloud

composition of two or more clouds

CloudDeployment Models



12/21

Cloud Software as a Service (SaaS) Use providers applications over a network

Cloud Platform as a Service (PaaS) Deploy customer-created applications to a cloud

Cloud Infrastructure as a Service (IaaS) Rent processing, storage, network capacity, and other

fundamental computing resources

To be considered cloud services are deployedon top of cloud infrastructure that has the keycharacteristics

CloudS

ervice Models



13/21

Issues with the Cloud Security (number 1 concern)

Performance

Availability Lack of Standards

Inability to Customize

Hard to Integrate with current in-house IT

Regulatory requirements

Note enough suppliers yet



14/21

Clouds are massively complex systems that can bereduced to simple primitives that are replicated

thousands of times

These complexities create many issues related to

security as well as all aspects of Cloud computing Clouds typically have a single security architecture

but have many customers with different demands

Cloud security issues may drive and define how we

adopt and deploy cloud computing solutions

Highly sensitive data is likely to be on private clouds

where organizations have complete control over

their security model

Analyzing CloudSecurity



15/21

More on Security

Trusting vendors security model Where is the data stored and who is securing it

Inability to respond to audit requirements

Indirect administrator accountability

Loss of physical control

Data retention / backup standards

Redundancy / Disaster Recovery

Handling Complianceo

GL

BA, HIPAA, SOX, PCYo State laws

o International EU Data Protection Directive

o FTC Scrutiny

o SAS 70 Audits



16/21

Core objectives and principles that cloudcomputing must meet to be successful: Security

Scalability

Availability

Performance

Cost-effective

Acquire resources on demand

Release resources when no longer needed Pay for what you use

Leverage others core competencies

Turn fixed cost into variable cost

Objectives of Cloud Computing



17/21

Cloud BasedService examples

Peer to Peer

BOINC, Skype

Web Apps

Facebook, Twitter, YouTube Security as a Service

MessageLabs, Purewire,

ScanSafe, Zscaler

Software plus services

Microsoft Online Services

Software as a Service

GoogleApps, Salesforce,

SpringCM

Storage

Content Distribution

BitTorret, Amazon

CloudFront

Sychronisation

LiveMesh



18/21

Clouds vs. Traditional Hosting

Three distinct characteristics that differentiateclouds from traditional hosting

It is sold on demand

Typically by the minute or the hour

It is elastic

A user can have as much or as little of a service as theywant at any given time

The service is fully managed by the provider The consumer needs nothing but a personal computer

and Internet access



19/21

Cloud Economics


Estimates vary widely on possible cost savingso If you move your data center to a cloud provider, it

will cost a tenth of the cost. Brian Gammage, Gartner Fellow

Use of cloud applications can reduce costs from 50%

to 90% - CTO of Washington D.C. IT resource subscription pilot demonstrated a 28% cost

savings - Alchemy Plus cloud (backing from Microsoft)

Using Cloud infrastructure saves 18% to 28% before

considering that you no longer need to buy peakcapacity George Reese, founder Valtira and enStratus

When implementing Cloud you must consider othercosts which may not be apparent today.


20/21

Recap Clouds

Provide internet based services

Available on demand

And fully managed by the provider

There is no one Cloud. There are many models andarchitectures

Clouds let you Avoid CapEx on hardware, software, and service

Share infrastructure and cost

Lower management overhead

Access a large range of apps

Many questions still remain!!!
