Cloudcomputing: lavorare direttamente su Internet sgazziano@johncabot.edu Sometimes called simply “the Net,” the Internet is a worldwide system of computer networks—a 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).
An Intranet sgazziano@johncabot.edu • 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.
Intranet v/s Internet sgazziano@johncabot.edu
Extranet sgazziano@johncabot.edu 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 enterprise’s 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.
Intranet v/s Internet, 2 PC Lab is here JCU facilities The “FIREWALL” connects intranet to internet Rest of the World (your laptop is here, at home) sgazziano@johncabot.edu X disk FTP area web sites (e.g. Facebook)
Local v/s Network sgazziano@johncabot.edu 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)
The World Wide Web sgazziano@johncabot.edu Runs on the Internet, Intranet, Extranet Uses the Hypertext Protocol (HTTP) We just call it the Internet, but it is a subset of it
Files on the Web sgazziano@johncabot.edu
Web server and web browser are different sgazziano@johncabot.edu
Real systems are a bit more complex, yes... sgazziano@johncabot.edu
Cloud computing sgazziano@johncabot.edu
Cloud Computing : software as a service sgazziano@johncabot.edu
Cloud computing types sgazziano@johncabot.edu
Cloud computing From system to services The « Cloud » is a group of serves, software, storage, processes, applications, data bases, data … Somewhere on the Net someoneknowswherethey all are stefano.gazziano@enea.it
Cloud computing Doesthatrememeberyou of something ? Perhaps the « mainframes of the ’70s ?? stefano.gazziano@enea.it
Cloud computing Correct: The mainframe isdistributed over the Net stefano.gazziano@enea.it
Cloud computing Is a major concept about usingstorage and processing power from computers and servers distributedoverall the world, and linked by the Internet a.k.a « The Grid » stefano.gazziano@enea.it
Cloud computing Users (usuallycompanies) are no more owners of their servers, but ratheraccess 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 highbandwiodht network, crucial to the efficiency of the system. Access to services isusually made via a web application, a browser. stefano.gazziano@enea.it
Cloud computing Cloud computingis a concept close to « power grid » Computing power and storageisoffered as « pay per use » by specializedcompanies As a matter of fact, companies do not needtheirown computers any more, but rely on a service company, whichguaranteescomputing power and storage « on demand » . stefano.gazziano@enea.it
Cloud computing Depending on the apoproacapproach, three « cloudcomputing » types maybelisted: Internalcloud externalprivateclouds public clouds This iswhatisknown as « elasticcomputingcapacity ». stefano.gazziano@enea.it
Cloud computing There are alreadymany IT systems « in the cloud » and many APIs to use API from Amazon, Amazon EC2 is one of the mostpopular. Manytools 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 virtualisationXen et le langage Java. egEclipseis a framework that allows users and developers to access arbitrary computing infrastructures(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”. stefano.gazziano@enea.it
Cloud computing Advantages Optimizescostscompared to traditionalsystems, allows the development of shared applications with no need of dedicated machines « in-house ». Actually, costsdepend on the duration of the service used : no investments (humanresources or machines) nécessite aucun investissement préalable (homme ou machine). The elasticity of the cloudalsoallows for evolutive services, whichmeansloadincreasecanbesupported. As an example, Salesforce.com, (Wikipedia) a pioneer in cloudcomputingnow has a customer base of more than 100,000 companies, serving millions of employees, with few thousands servers (1000 on March 2009). stefano.gazziano@enea.it
Cloud computing Hazards Secure accessto applications between client and remote servers. General security of company network. Data on a cloud service are generallysaferthan on a local storage. It isanyway possible to store sensible data within the companyprotected areas, on an Intranet or Extranet. stefano.gazziano@enea.it
