What is Cloud Computing? :What is Cloud Computing? “Cloud” is simply a metaphor for the internet Users do not have or need knowledge, control, ownership in the computer infrastructure Users simply rent or access the software, paying only for what they use Simple Introduction to Cloud Computing


History of Cloud Computing :History of Cloud Computing Concept dating back to the 1960’s by John McCarthy, a computer scientist, brought up the idea that "computation may someday be organized as a public utility” Idea that revolutionized Cloud Computing: Moving from clustering computing to grid computing Clustering Grid “In some ways, the cloud is a natural next step from the grid-utility model,” said Frank Gens, an analyst at the research firm IDC


The “Super Computer” in the Sky :The “Super Computer” in the Sky Two ways of building a “super computer” with enough power that users can plug into according to their needs at a particular time: Blue Gene Approach Google's Approach


Early Leaders in the Industry :Early Leaders in the Industry In 2007, Microsoft made available free software, www.live.com that connects its Windows operating system to software services delivered on the Internet Launched in July 2002, Amazon Web Services provided online services for other web sites or client-side applications 3tera launched its AppLogic system in February, 2006 IBM’s system introduced in the mid 2000’s is called Blue Cloud


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


Functionality :Functionality Cloud computing is an emerging technology that is revolutionizing IT infrastructures and flexibility, and software as a service (SaaS) 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 Customer retention is vital, especially today in our economy.


Functionality :Functionality Software and applications are extremely costly. With cloud, you rent so the heavy investment is forgone 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 Computing Replacing :What Technologies is Cloud Computing Replacing Cloud computing is replacing large Corporate Data Centers and unnecessary, expensive private server infrastructure. 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 Computing :Companies Leading in Cloud Computing


Slide 11:“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 Google has invested more than $2 billion a year in data centers for cloud computing. By far the leader in the technology Marissa Mayer, Vice President, Search Products & User Experience, talks about Google Clouds, its product, uncertainties and future expansions and ideas Click here for video


Slide 12: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


Slide 13:“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.

Scalable Pricing and Cloud Computing :Scalable Pricing and Cloud Computing Models of Pricing Free Subscription Model Pay Per Use Perpetual License Enterprise Unlimited License Click here for an example of Amazon's Pricing


What do these Services Offer an Organization? : What do these Services Offer an Organization? Cloud computing will lead to increase in the following categories: Virtualization Usability Standardization Scalability


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


Infrastructure as a Service :Infrastructure as a Service Defined as delivery of computer infrastructure as a service Fully outsourced service so businesses do not have to purchase servers, software or equipment 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 Service :Platform as a Service Provides all the facilities necessary to support the complete process of building and delivering web applications and services, all available over the internet Infrastructure providers can transparently alter the platforms for their customers’ unique needs


Software as a Service :Software as a Service Defined as service-on-demand, where a provider will license software tailored 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 To see how Salesforce and Google come together watch here


Cloud Computing Pros :Cloud 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 Cons :Cloud Computing Cons Security Issues (#1 concern) Internet connection Too many platforms Location of Servers Time for Transition Speed


The Future of Cloud Computing :The Future of Cloud Computing


Cloud is in the Infancy Stage :Cloud is in the Infancy Stage Many companies are only using cloud computing for small projects. The trust hasn’t been accepted Details such as licensing, privacy, security, compliance and network monitoring need to be finalized for the trust to be realized


Future Educational Uses :Future Educational Uses An expansion of Microsoft live@edu View Video More useful spending of technology budgets Classroom collaboration View an example from AirSet.com Take a quick tour Office Web Applications Google Docs View Video


Future Personal Uses :Future Personal Uses No more backing up files to thumb drives or syncing computers together Services replace devices A single hard drive for the rest of a person’s life, accessible anywhere with internet


Expansion :Expansion Resources are expected to triple by 2012, from $16 billion to $42 billion Cloud computing is said to be the foundation of the next 20 years of IT technology


Recommendations :Recommendations Too early for large companies to migrate Migrate after adequate development time Good investment for small businesses Personal use will become more prevalent
