Cloud computing refers to storing and accessing data and programs over the Internet instead of a local computer's hard drive. It offers cost savings, scalability, and accessibility from any Internet-connected device. However, some concerns include security, reliability if a provider has an outage, and whether data is retrievable. For education, cloud computing allows students to access common workspaces and software from anywhere, and ensures all students use the same up-to-date versions. Several universities and companies are partnering to provide academic cloud resources to students.

Editor's Notes
- Cloud computing is known as many different things, because it is such a new concept. With the rise and popularity of the Web 2.0 Application, it is becoming more difficult to define Cloud Computing. Some analysts say that the term “Cloud” mean anything that is outside of the companies firewall and other say that the cloud is the actual connection to the Internet. For the purpose of this presentation and to make it simple, we will refer to the cloud as the “Internet.”
- Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like a public utility.It is a paradigm shift following the shift from mainframe to client-server that preceded it in the early '80s. Details are abstracted from the users who no longer have need of, expertise in, or control over the technology infrastructure "in the cloud" that supports them.[1] Cloud computing describes a new supplement, consumption and delivery model for IT services based on the Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.[2][3] It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.[4]The term cloud is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network,[5] and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents.[6] Typical cloud computing providers deliver common business applications online which are accessed from another web service or software like a web browser, while the software and data are stored on servers.Most cloud computing infrastructure consists of reliable services delivered through data centers and built on servers. Clouds often appear as single points of access for all consumers' computing needs. Commercial offerings are generally expected to meet quality of service (QoS) requirements of customers and typically offer SLAs.[7]
- Now we will look at the concerns and Benefits of cloud computing.
- There are many business benefits when it comes to using cloud computing services. One of the most important benefits for the businesses where many of our students work as well as ESC is the cost savings that a business gets with using cloud computing services. Customer only pay for the resources that they use. They do not have to worry about paying that up front capital with investing in infrastructure and application license. An example of this would be using the Enterprise version of the Google Applications. A business would pay just $50 per day of usage as compared to Microsoft Office Professional that charges $499.99 for licenses and has to be renewed every year. Once you are done with the project that you are working with the Google Apps, you do not have to pay for it anymore, until you have to use it again.
- Another Benefit to cloud computing would be Scalable services and applications. Cloud computing allows for you to use applications from a remote location and you pay for the use and service, so lets just say for example that your company starts off from a small 100 employee company. Then you will only need to pay for applications being used by those 100 employees. Then lets say that times get difficult and you have to lay off some of your employees. You are still able to do this without having un-used licensed software laying around, not being used. Cloud computing can work for you no matter if your business gets larger or smaller.Another benefit would be redundancy and disaster recovery. This is great for customer of cloud computing, because they know that cloud computing providers have the ability to have a back-up and disaster recovery plan, so that not only you, the business has their information safe, but the CC provider does also. This is a great way for a business to know that thir information will be safe.
- That are some concerns for business that are thinking about adopting CC services. Many businesessare concerned that their CC service provider would not have the updated new software services or updates that the business may need to do their projects. They also have reliability concerns which could potentially slow down production of their business needs. An example of this would be the power outage that Amazon had. Customers feel like this could happen with any CC service providers, and this would have an enormous impact on business needs, as they would not be able to retrieve documents, information or meet customer needs. Another IT concern would be the fear of change for the CC service providers. The reality is that technologies is changing at an alarmingly rapid rate and CC providers must keep up for the business to stay competitive.Some other concerns are Regualtions in general. Exmaples of this would be HIPPA regulations that have to do with the security and privacy of health care customers’ information. This information is very private, and with using CC this infomratoin could potntailly be stored on a remote server in another part of the country and this may go against some HIPPA rules. Another regulation issue would be the Sabanes Oxley which has to do with corporations financial reportings and informations.
- Next we will talked about the anatomy of cloud computing.
- Here are the 3 layers of the cloud computing anatomy. The Infrastructure is the actual hardware that serves as a storage device. The platform contains all the resources from which you may select based on your business needs. The application contains the software from which you can choose such as MS Word.
- Software as a service or SaaS, is a model of software deployment over the internet. A license for the application is provided to the user for use as a service on demand. This is done through either a subscription or pay as you go. This allows for vendors to develop, host and operate software for their customers use. Rather than purchase the hardware and software to run an application, the customers need only a computer or a server to download the application and internet access to run the software. The software can be licensed for a single user or for a group of users. The software is centrally managed at the providers data center location. The model for the application deployment is one to many, which means that on application program can be used by many customers. Software vendors may host the application on their own web servers or upload them to the customers device and disable it after use or after the on-demand contract expires. It is easier to get new features of the applications are easily accessible, because they are upgraded by the application providers.
- The benefits of using SaaS is that the customer:Saves money by not having to purchase servers or other software to support use. Everything runs from the browser.Allows business to focus budgets on competitive advantage rather than infrastructureMonthly obligation rather than up front capital costReduced need to predict scale of demand and infrastructure investment up front as available capacity matches demandMulti-Tenant efficiencyFlexibility and scalabilityEasy to use
- PaaS offerings facilitate deployment of applications without the cost and complexity of buying and managing the underlying hardware and software and provisioning hosting capabilities. Providing all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely available from the Internet.Add-on development facilities allow customization of existing SaaS applications, and in some ways are the equivalent of macro language. Customization facilities provided with packaged software applications such as Lotus Notes, or Microsoft Word. Often these require PaaS developers and their users to purchase subscriptions to the co-resident SaaS application.Stand alone development environments Stand-alone PaaS environments do not include technical, licensing or financial dependencies on specific SaaS applications or web services, and are intended to provide a generalized development environment.Application delivery-only environments Some PaaS offerings lack development, debugging and test capabilities, and provide only hosting-level services such as security and on-demand scalability.Open Platform as a Service Lets the developer use any programming language, any database, any operating system, any server, etc.
- Infrastructure as a Service or IaaS delivers computer infrastructure, typically a platform virtualizationenvironment as a service. Rather than purchasing servers, software, data center space or network equipment, clients instead buy those resources as a fully outsourced service. The service is typically billed on a utility computing basis and amount of resources consumed (and therefore the cost) will typically reflect the level of activity. It is an evolution of virtual private server offerings.
- Now we will talk about Public, Private, and Hybrid clouds.
- Here is a diagram that shows the properties of both Public and private clouds. You can see that there are seven elements of value that fall in three “value types”: economic, architectural and strategic.The economic value of Cloud is about being able to have the timing and size of the investments you make with the value you receive – variously referred to as “pay as you go.” You don’t pay $millions for infrastructure that only give you value months or years later; you pay for what you actually need and when you use it. The architectural value of Cloud is about having an simpleenvironment that developers and operations hide a lot of complexity, making it much quicker and easier to develop and deploy applications.The strategic value of Cloud platforms help you focus on what makes your organization more effective and different, and leave all the other stuff to a third party that is dedicated to doing a great job for a competitive price. This is about focus and it’s also about avoiding having to train people to do things that fundamentally don’t add value to your organization.CHANGE SCREEN VIEWAs you can see a public cloud has all of these 7 elements
- The private cloud only has the Architectural elements. We will discuss why this is in more detail.
- The public clouds are open for anyone to use, as long as they have access to the cloud components. There are reliability concerns for public clouds, because there is usually not much support for public clouds and there is no guarantee that the information will be there above paid users’ information. Public clouds are on a large scale infrastrucure, because it is open to the public, so therefore the provider needs to be able to have enough storage and devices to keep track of the applications and users stored data. These public clouds are self-service. Because they are sometimes a free service, so everything that the customer wants to do, is usually on their terms for figuring out how to use the public services. The 7 elements describe the use of the public cloud: Utility pricing- you are charged on what you use (if their services are not free), Elastic resource capacity- your recsouces can be changed depending on needs. You can use more or less at any giving time, Virtualized resources- most of the resources that you use are usually held on one device, in order to save space for the provider, Management Automation-, Self-service provisioning- this system is self serve and the user is the one to keep track of their information and data, Third party owernship- the applications and services that are provided to the customer, are owned and operated by another outside sourced company. The customer does not have to worry about keeping the systems and applications up to date, this is the job of the third party provider, managed operations- this when the third party providers would own the devices and services and they would be the ones to managed the operations of the devices and systems to make sure everything is running properly.
- Private clouds are within the companies firewall, this mean that the company houses all computing equipment inside the company. The company had control over all the resources used within the computing process, so they know what is being done and which devices are being used at all times. These private networks are more secure than than the public networks, because they are owned by the company, and will want to have more restictions on their information. Also, since the company owns their computing network, they will have the ideal apps they need to complete their business needs. Private networks only use 3 of the 7 elements. They only use the arctiectual section of the elements. Many analyst say that the private networks really do not count as the ideal cloud computing concept. They do not save the up front capital with investing in infrastructure and services. Private clouds work more as an application server more than a cloud computing service.
- The hybrid cloud is a mixture of Private and Public clouds. They are more like the ideal cloud comptuing service that many companies offer. You get the avaialbity of the public cloud but the security of the private cloud. You can use your private cloud computing resources for what you need to use it for, but if you need more resouces, because a spike in demand from you customers, then you can lean on the public cloud networks to help you outsouce you demand load. This would make it possible to pull applications from the private networks out to the public networks for use in the demand. The challenge for this would be pulling your resources back inside your private network from the public network. need a policy engine so your systems can figure out when to do this and with what.
- Next we will talk about how cloud computing is being used in schools domestic and international.
- http://campustechnology.com/articles/2010/02/18/ibm-launches-academic-cloud.aspx?sc_lang=en
- IBM has teamed with three universities in Qatar - Carnegie Mellon University in Qatar, Qatar University, and Texas A&M University at Qatar - to open up its cloud infrastructure to local businesses and industries to test applications and complete various projects, including seismic modeling and the exploration for oil and gas. This is in addition to an Arabic language Web search engine and the testing and migration of various applications using Hadoop / MapReduce programming methods
- The South African effort, done in conjunction with the Computational Intelligence Research Group at the University of Pretoria, is using cloud computing for next-generation medical research. Students, said IBM, hope to find "ways to slow the progression of serious illnesses by studying drug absorption rates and protein structure folding of a person's DNA once introduced to a certain type of medication."
- Finally, in Japan, IBM is working with the students at Kyushu University through Societal Information System Engineering classes, as they are called. These classes, besides showing how to understand the cloud computing management system and design applications and cloud infrastructures, are also teaching these IT engineers ethical standards and what IBM says is "foresight about long-term changes in social conditions and ... how todevelop information technology accordingly."
- Live@edu is the ultimate suite of applications for mobile, desktop and web-based to help students to collaborate on campus, and create a community. Microsoft Office Live Workspace is an online place to save, access, and share documents and files. Microsoft SharedView allows for you to share your desktop with up to 15 users. Windows Live spaces Let students set up a space for group projects, campus clubs, or personal pages. Windows Live Messenger lets you have Group chat with up to 15 others. Windows Live Messenger lets you look at photos together, right in the conversation window, sharing folders, share documents too large to send as attachments, send SMS message from Messenger interface. Microsoft DreamSpark gives students professional-level developer and design tools. In the past four months more than 5,000 schools have enrolled with Live@edu, joining the thousands of other institutions in more than 100 countries already providing Live@edu to tens of millions of students worldwide.
- University of Cincinnati has an extensive 55,000 Live@edu deployment, including user identity management and password synchronization with ILM, a single sign-on portal and more. Students can launch any of the Live@edu applications directly from their Blackboard home page and synchronize with their class schedules.
- Ohio University is almost done activating more than 140,000 Live@edu accounts for current students and alumni. While the school is looking to reduce costs and improve communications with alumni, students cite the modern web interface, increased mailbox capacity and powerful search capabilities as top features
- Finally, we will look at the future of cloud computing and how business are expanding their cloud computing services.
- Merrill Lynchestimates that within the next five years, the annual global market for cloud computing will surge to $95 billion. In a May 2008 report, Merrill Lynch estimated that 12% of the worldwide software market would go to the cloud in that period. IBM will build a $360 million data center at its facility in Research Triangle Park, North Carolina to power cloud computing applications for customers. IBM is focused on building cloud data centers in which its enterprise customers can run their own applications. IBM owns or operates more than 450 data centers worldwide.
- Here are some big named players in the cloud computing industry. VMware grew to $1.9 billion in sales by proffering virtualization software that helps companies slice costs by loading up computers with more work, cutting hardware and power costsVMware released key pieces of anambitious new product that's designed to help companies more efficiently juggle complex computing tasks. Dubbed the Virtual Data Center Operating System, the software creates a bank of computers, storage devices, and networking equipment that a company can tap at will, as computing needs arise. Cisco come out with a new Cloud computing storage device called the Unified Computing System. This is the next-generation data center platform accelerates the delivery of new services simply, reliably, and securely through end-to-end provisioning and migration support. This device radically reduces the number of devices requiring setup, management, power, cooling, and cabling.
- Here is a chart of the pricing that Amazon charges for using their cloud computing services. As you can see that they charge by the hour. The customer is paying for the resources that they use and only when they need to use it.
- Here is another pricing system that Microsoft uses for their cloud computing services. They have more options to their pricing, because they allow for you to by for storage if you need it and have data transferring services.
