7 Cloud computing: lavorare direttamente su Internet Sometimes called simply the Net, the Internet is a worldwide system of computer networksa network of networks hence Internet, in which users at any one computer can get information from any other computer The Internet uses a portion of the total resources of the currently existing public telecommunication networks. Technically, what distinguishes the Internet is its use of a set of protocols called TCP/IP (Transmission Control Protocol/Internet Protocol).

8 An Intranet An intranet is the use of Web technologies to create a private network, usually within one enterprise. It is typically a complete LAN, or several intra- connected LANs Intranets are used for: – work-group activities – the distributed sharing of projects within the enterprise – Controlled access to company financial documents – use of knowledge management, research materials, online training, and other information that requires distribution within the enterprise.

9 Intranet v/s Internet

10 Extranet Connect several intranets via the Internet, by adding a security mechanism and some additional functionalities They form a larger virtual network that allows remote users (such as business partners or mobile employees) to securely connect over the Internet to the enterprises main intranet. Extranets are also employed by two or more enterprises (suppliers & buyers) to share information in a controlled fashion, and therefore they play a major role in the development of business-to- business electronic commerce and Supply Chain systems.

11 Intranet v/s Internet, 2 X disk FTP area web sites (e.g. Facebook) JCU facilities Rest of the World (your laptop is here, at home) The FIREWALL connects intranet to internet PC Lab is here

12 Local v/s Network Local = on your machine(e.g.C:/programs) Local Network = « Intranet » X: shared disk (user permissions, permanent) O: temporary area (cleared periodically) Accessible only from within JCU premises Network, a.k.a. « cloud » Google docs MS Office 2010 (near future)

13 The World Wide Web Runs on the Internet, Intranet, Extranet Uses the Hypertext Protocol (HTTP) We just call it the Internet, but it is a subset of it

14 Files on the Web

16 Web server and web browser are different

17 Real systems are a bit more complex, yes...

18 Cloud computing

19 Cloud Computing : software as a service

20 Cloud computing types

21 John Cabot University Cloud computing From system to services The « Cloud » is a group of serves, software, storage, processes, applications, data bases, data … Somewhere on the Net someone knows where they all are

22 John Cabot University Mars Tunis Cloud computing Does that rememeber you of something ? Perhaps the « mainframes of the 70s ??

23 John Cabot University Mars Tunis Cloud computing Correct: The mainframe is distributed over the Net

24 John Cabot University Mars Tunis Cloud computing Is a major concept about using storage and processing power from computers and servers distributed overall the world, and linked by the Internet a.k.a « The Grid »

25 John Cabot University Mars Tunis Cloud computing Users (usually companies) are no more owners of their servers, but rather access a number of services available online with no need to maintain and manage the underlying infrastructure Applications and data are no more stored on local computers but « in the cloud », on a number of servers in different locations and interconnected by a high bandwiodht network, crucial to the efficiency of the system. Access to services is usually made via a web application, a browser.

26 John Cabot University Mars Tunis Cloud computing Cloud computing is a concept close to « power grid » Computing power and storage is offered as « pay per use » by specialized companies As a matter of fact, companies do not need their own computers any more, but rely on a service company, which guarantees computing power and storage « on demand ».

27 John Cabot University Mars Tunis Cloud computing Depending on the apoproacapproach, three « cloud computing » types may be listed: Internal cloud external private clouds public clouds This is what is known as « elastic computing capacity ».

28 John Cabot University Mars Tunis Cloud computing There are already many IT systems « in the cloud » and many APIs to use API from Amazon, Amazon EC2 is one of the most popular.Amazon EC2 Many tools are compatible with Amazon EC2 APIs. Eucalyptus, Open system enabling the creation of on-premise Infrastructure as a Service clouds, with no requirements for retooling the organization's existing IT infrastructure or for introducing any specialized hardware.système libre utilisant de la virtualisation Xen et le langage Java.Eucalyptus egEclipse is a framework that allows users and developers to access arbitrary computing infrastructures (video). gEclipse (video) DotRiver. fully Open Source integrated desktop virtualization product in the market today. Offers total control of your workstations, Whatever their type, their configuration, their use, organization or technical architecture, whatever your needs and for all of your software.DotRiver.

29 John Cabot University Mars Tunis Cloud computing Advantages Optimizes costs compared to traditional systems, allows the development of shared applications with no need of dedicated machines « in-house ». Actually, costs depend on the duration of the service used : no investments (human resources or machines) nécessite aucun investissement préalable (homme ou machine). The elasticity of the cloud also allows for evolutive services, which means load increase can be supported. As an example, Salesforce.com, (Wikipedia) a pioneer in cloud computing now has a customer base of more than 100,000 companies, serving millions of employees, with few thousands servers (1000 on March 2009).Salesforce.com(Wikipedia)

30 John Cabot University Mars Tunis Cloud computing Hazards Secure access to applications between client and remote servers. General security of company network. Data on a cloud service are generally safer than on a local storage. It is anyway possible to store sensible data within the company protected areas, on an Intranet or Extranet.Intranet Extranet

31 John Cabot University Mars Tunis Cloud computing Technology : The virtual machinevirtual machine Virtualization means to use a single computer like many computers at the same time. Software emulates Hardware = Total flexibility
