1. Service Oriented Architecture(SOA) A study report Prepared by: Abhik Tushar Das and Anil Kumar Sahu Management Information System (MIS) Monday, 28 March 2011 1 Abhik Tushar Das / Anil Kumar Sahu
2. What is SOA Monday, 28 March 2011 2 Abhik Tushar Das / Anil Kumar Sahu A SYSTEM BASED ON A SOA WILL PACKAGE FUNCTIONALITY AS A SUITE OF INTEROPERABLE SERVICES THAT CAN BE USED WITHIN MULTIPLE SEPARATE SYSTEMS FROM SEVERAL BUSINESS DOMAINS
3. Why SOA? Monday, 28 March 2011 3 Abhik Tushar Das / Anil Kumar Sahu
4. The Enterprise Application Integration. Monday, 28 March 2011 4 Abhik Tushar Das / Anil Kumar Sahu Several disparate departments within a company may develop and deploy SOA services in different implementation languages; their respective clients will benefit from a well understood, well defined interface to access them. XML is commonly used for interfacing with SOA services, though this is not required

10. Tenets of SOA Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 10
11. Advantage SOA SOA advocates usage of multi utility modules meant to work in tandem with many others so that they can be plugged wherever necessary; the modules are meant to work as services which work along with other services to serve a purpose Hence; managing, modifying, replacing the services become a much easier task. SOA defines how to integrate widely disparate applications for a Web-based environment and uses multiple implementation platforms. Rather than defining an API (application programming interface), SOA defines the interface in terms of protocols and functionality. An endpoint is the entry point for such a SOA implementation Monday, 28 March 2011 11 Abhik Tushar Das / Anil Kumar Sahu
13. The connecting medium Web 2.0 is a set of standards globally accepted to elevate web experience by usage of various web controls (textboxes, buttons, display methods, etc) to make websites more interactive, more intelligent and accessible though various modes like browsers, tablets, mobiles etc Web 2.0 use the following key terms: Support for Ajax, XML, multi media apps like Flash, Flex, JavaScript and support seamless experience while accessing data intensive sites like photo archives (picassa, flicker), documentation site (Google docs).

20. SOA facts Myths SOA is a technology SOA require Web Services SOA is new and revolutionary SOA ensures the alignment of IT and business A SOA Reference Architecture reduces implementation risk SOA requires a complete technology and business processes overhaul We need to build a SOA Facts SOA is a design philosophy independent of any vendor, product, technology or industry trend. Purchasing your SOA infrastructure from a single vendor defeats the purpose of investing in SOA. SOA may be realized via Web services but Web services are not necessarily required to implement SOA EDI, CORBA and DCOM were conceptual examples of SO SOA is not a methodology SOA should be incremental and built upon your current investments SOA is a means, not an end Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 20
21. Evolution of Web 2.0 from Web 1.0 Monday, 28 March 2011 AbhikTushar Das / Anil Kumar Sahu 21
22. www & Web 2.0 History The World Wide Web (WWW) was created in 1989 by CERN physicist Tim Berners-Lee. On 30 April 1993. CERN announced that the World Wide Web would be free to use for anyone. Before the introduction of HTML and HTTP, other protocols such as file transfer protocol and the gopher protocol were used to retrieve individual files from a server. These protocols offer a simple directory structure which the user navigates and chooses files to download. Documents were most often presented as plain text files without formatting, or were encoded in word processor formats. The term Web 2.0 closely associated with Tim O'Reilly due to O'Reilly Media Web 2.0 conference in late 2004. Web 2.0 suggests a new version of the WorldWideWeb. Web 2.0 refers to cumulative changes in the ways software developers and end-users use the Web. Notion of Web 2.0 is qualitatively different from prior web technologies has been challenged by World Wide Web inventor Tim Berners-Lee. Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 22
23. Web 2.0 Web 2.0 is a set of standards globally accepted to elevate web experience by usage of various web controls (textboxes, buttons, display methods, etc) to make websites more interactive, more intelligent and accessible though various modes like browsers, tablets, mobiles etc Web 2.0 use the following key terms: Support for Ajax, XML, multi media apps like Flash, Flex, JavaScript and support seamless experience while accessing data intensive sites like photo archives (picassa, flicker), documentation site (Google docs).

24. Web 2.0 Geo Mapping applications Web 2.0 has evolved the new way of knowing our world geographically in a better way through various mapping service providers. Net surfers can view satellite images, street level images,Navigation images Few service providers even provide 3-D mapping. Most service providers provide free of cost service Examples: Yahoo! Maps GoogleMaps GoogleEarth Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 24

26. Web 2.0 Basic Architecture Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 26
27. Website domains A generic top-level domain (gTLD) is one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. Overall, IANA currently distinguishes the following groups of top-level domains: infrastructure top-level domain (arpa) country-code top-level domains (ccTLD) internationalized top-level domains (IDNs) internationalized country code top-level domains testing top-level domains Domain classification examples: .com ---commercial .edu ---educational website .gov ---government website .mil --- US military website . org --- organizational website Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 27
28. Internet access Overview The estimated population of Internet users is 1.97 billion as of 30 June 2010. From 2009 onward, the Internet is expected to grow significantly in Brazil, Russia, India, China, and Indonesia (BRICI countries). These countries have large populations and moderate to high economic growth, but still low Internet penetration rates. In 2009, the BRICI countries represented about 45 percent of the world's population and had approximately 610 million Internet users, but by 2015, Internet users in BRICI countries will double to 1.2 billion, and will triple in Indonesia. After English (27%), the most requested languages on the World Wide Web are Chinese (23%), Spanish (8%), Japanese (5%), Portuguese and German (4% each), Arabic, French and Russian (3% each), and Korean (2%). By region, 42% of the world's Internet users are based in Asia, 24% in Europe, 14% in North America, 10% in Latin America and the Caribbean taken together, 6% in Africa, 3% in the Middle East and 1% in Australia/Oceania Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 28
29. Web Browser The continuous development in the operative enhancement of web browsers played a major role in development of Web 2.0 Most used Web Browsers: Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 29
31. Web 2.0 evolution Associated with web applications. facilitation of participatory information sharing, interoperability, user-centered design, and collaboration on the World Wide Web. A Web 2.0 site allows users to: interact and collaborate with each other in a social media dialogue as creators (prosumers) of user-generated content in a virtual community, in contrast to websites where users (consumers) are limited to the passive viewing of content that was created for them. Examples of Web 2.0 Applications : social networking sites blogs Wikis video sharing sites hosted services web applications Mashups folksonomies. Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 31
32. Social networking sites Social software applications such as social bookmarking and photograph annotation. Tagging, which is one of the defining characteristics of Web 2.0 services, allows users to collectively classify and find information. Some websites include tag clouds as a way to visualize tags in a folksonomy. Early social networking on the World Wide Web began in the form of generalized online communities such as Theglobe.com (1994), Geocities (1995) and Tripod.com (1995). Popular methods now combine many of these, with Facebook and Twitter widely used worldwide/ MySpace and LinkedIn being the most widely used in North America. Nexopia (mostly in Canada); Bebo, VKontakte, Hi5, Hyves (mostly in The Netherlands). StudiVZ (mostly in Germany). iWiW (mostly in Hungary) Tuenti (mostly in Spain) Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 32
33. Blog A blog (a blend of the term web log) is a type of website or part of a website. Blogs are usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. Blog can also be used as a verb, meaning to maintain or add content to a blog. Most blogs are interactive, allowing visitors to leave comments and even message each other via widgets on the blogs and it is this interactivity that distinguishes them from other static websites. Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. The ability of readers to leave comments in an interactive format is an important part of many blogs. Monday, 28 March 2011 AbhikTushar Das / Anil Kumar Sahu 33

Twitter, Facebook, Orkut , LinkedIn and MyFrenz.net in India Examples: Twitter,Blogger. Social impact of blogging in society on internet: Very recently “Jasmine Revolution”, the political revolution in Arab states Public expression and awareness on issues like “Global Warming”,world hunger. Cultural, economic, ethical, educational aspects redefined and modified. Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 34
35. Blog content types Most blogs are primarily textual some focus on art (art blog) photographs (photoblog) videos (video blogging) music (MP3 blog) audio (podcasting) Microblogging is another type of blogging featuring very short posts. Examples: Blogger by Google WordPress Movable Type LiveJournal Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 35
36. Wikis A Wiki is a website that allows the creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor. Wikis are typically powered by wiki software and are often used to create collaborative works. Examples include community websites, corporate intranets, knowledge management systems, and note services. The software can also be used for personal note taking. Examples: Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 36
37. Video hosting service A video hosting service allows individuals to upload video clips to an Internet website. The video host will then store the video on its server, and show the individual different types of code to allow others to view this video. The website, mainly used as the video hosting website, is usually called the video sharing website. many users do not have unlimited web space, either as a paid service, or through an ISP offering, video hosting services are becoming increasingly popular, especially with the explosion in popularity of blogs, forums, and other interactive pages. The mass market for camera phones has increased the supply of user-generated video. Traditional methods of personal video distribution, such as making a DVD to show to friends at home, are unsuited to the low resolution and high volume of camera phone clips. In contrast, current broadband Internet connections are well suited to serving the quality of video shot on mobile phones. Most people do not own web servers, and this has created demand for user-generated video content hosting. Examples: Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 37
38. SaaS applications enabling Web 2.0 Development SaaS : Software as a service sometimes referred to as "software on demand“ It is software that is deployed over the internet and/or is deployed to run behind a firewall on a local area network or personal computer. With SaaS, a provider licenses an application to customers either as a service on demand, through a subscription, in a "pay-as-you-go" model. At current trends SaaS providers at no charge when there is opportunity to generate revenue from streams other than the user, such as from advertisement or user list sales This approach to application delivery is part of the utility computing model where all of the technology is in the "cloud" accessed over the Internet as a service. Examples: Brothersoft , Cnet, softpedia etc. Monday, 28 March 2011 Abhik Tushar Das / Anil Kumar Sahu 38
39. Web 2.0 Datafiles download & upload applications File Sharing (upload &download) service provider websites on free of paid subscription model enable data mining to internet surfers. Examples: Bittorrent protocol: BitTorrent is a peer-to-peer file sharing protocol used for distributing large amounts of data. BitTorrent is one of the most common protocols for transferring large files, and it has been estimated that it accounted for roughly 27% to 55% of all Internet traffic (depending on geographical location) as of February 2009 P2P file hosting, transfer & simultaneous upload & download(seed & peer sharing).
