What is Cloud Computing?What is Cloud Computing?

ó “Cloud” is simply a metaphor for the internet

ó Users do not have or need knowledge, control, ownership in the computer infrastructure

ó Users simply rent or access the software, paying only for what they use

ó Simple Introduction to Cloud Computing

Potential Issues Potential Issues

• Data residency – time delay between data being requested and delivered

• Security and confidentiality of data being stored outside the company

• Business buy-in; convincing companies of the infrastructure and reliability

FunctionalityFunctionalityó Cloud computing is an emerging technology that is

revolutionizing IT infrastructures and flexibility, and softwareas a service (SaaS)

ó During this economic time of recession, there are huge cost-reduction pressures and cloud computing allows businesses to do just that by tapping into cloud computing platforms on a pay-as-you-go basis

ó Customer retention is vital, especially today in our economy.

Functionality Functionality

ó Software and applications are extremely costly. With cloud, you rent so the heavy investment is forgone

ó Cloud computing is a set of technologies and business practices that enable companies of all sizes to build, deploy, monitor and scale applications using resources accessed over the internet

What Technologies is Cloud What Technologies is Cloud Computing ReplacingComputing Replacing

ó Cloud computing is replacing large Corporate Data Centers and unnecessary, expensive private server infrastructure.

ó Web 2.0, SaaS, Enterprise and government users are adopting cloud computing because it eliminates capital investment in hardware and facilities as well as reduces operations labor

Companies Leading in Cloud Companies Leading in Cloud ComputingComputing

ó “Google 101”– Network made up of millions of cheap servers, that would store staggering

amounts of data, including numerous copies of the world wide web– Makes search faster, helping ferret out answers to billions of queries in a

fraction of a second

ó Google has invested more than $2 billion a year in data centers for cloud computing.

ó By far the leader in the technology

ó Amazon Elastic Compute Cloud “Amazon EC2”– web service interface that provides resizable computing capacity in a cloud

– designed to make web-scale computing easier for developers

– reduces the time required to obtain and boot new server space from weeks to minutes

– allows developers to pay only for capacity that they actually use

ó “Azure”– Internet-scale cloud computing and services platform hosted in

Microsoft data centers– Provides a range of functionality to build applications that span from

consumer web to enterprise scenarios – Designed to help developers quickly and easily create, deploy, manage,

and distribute web services and applications on the internet.

What do these Services Offer an What do these Services Offer an Organization?Organization?

ó Cloud computing will lead to increase in the following categories:– Virtualization– Usability– Standardization– Scalability

Cloud Computing UsageCloud Computing Usage

ó Cloud Computing has 3 major uses:– Infrastructure as a Service– Platform as a Service– Software as a Service

Infrastructure as a ServiceInfrastructure as a Service

ó Defined as delivery of computer infrastructure as a service• Fully outsourced service so businesses do not have to purchase servers,

software or equipment

ó Infrastructure providers can dynamically allocate resources for service providers• Service providers offer this service to end users

• Allows cost savings for the service providers, since they do not need to operate their own datacenter

• Ad hoc systems allow quick customization to consumer demands

Platform as a ServicePlatform as a Service

ó Provides all the facilities necessary to support the complete process of building and delivering web applications and services, all available over the internet

ó Infrastructure providers can transparently alter the platforms for their customers’ unique needs

Software as a ServiceSoftware as a Serviceó Defined as service-on-demand, where a provider will license

software tailored ó Infrastructure providers can allow customers’ to run

applications off their infrastructure, but transparent to the end user• Customers can utilize greater computing power while saving on the

following– Cost– Space– Power Consumption– Facility

Cloud Computing ProsCloud Computing Pros

• Reduced Hardware equipment for end users• Improved Performance• Lower Hardware and Software Maintenance• Instant Software Updates• Accessibility• Less Expensive (Amazon example)• Better Collaboration• Pay for what you use• Flexible

Cloud Computing ConsCloud Computing Cons

• Security Issues (#1 concern)• Internet connection• Too many platforms• Location of Servers• Time for Transition • Speed

The Future of Cloud ComputingThe Future of Cloud Computing

Cloud is in the Infancy StageCloud is in the Infancy Stageó Many companies are only using cloud computing for

small projects.ó The trust hasn’t been acceptedó Details such as licensing, privacy, security, compliance

and network monitoring need to be finalized for the trust to be realized

Future Personal UsesFuture Personal Usesó No more backing up files to thumb drives or syncing

computers togetheró Services replace devicesó A single hard drive for the rest of a person’s life,

accessible anywhere with internet
