2 University of Southern California Center for Systems and Software Engineering Too many choices !!! 2

3 University of Southern California Center for Systems and Software Engineering Why Web Services? Interoperability has Highest Priority Web Services take Web-applications to the Next Level Web Services have Two Types of Uses –Reusable application-components. –Connect existing software. 3

4 University of Southern California Center for Systems and Software Engineering Web Services in the news 4

5 University of Southern California Center for Systems and Software Engineering Examples of Cloud Computing on the go No need for local data storage – Humyo, ZumoDrive, Microsoft’s SkyDrive, S3 from AmazonHumyoZumoDriveSkyDriveS3 Collaboration Space –Google Wave, Spicebird, Mikogo, Stixy and VyewSpicebirdMikogoStixyVyew Working in a virtual office –Google’s online suite, Ajax13, ThinkFree and Microsoft’sOffice Live.online suiteAjax13ThinkFreeOffice Live Need extra processing power – AbiCloud, Elastichosts and NASA’s Nebula platform.AbiCloudElastichostsNebula 5

6 University of Southern California Center for Systems and Software Engineering Services in Cloud Computing Infrastructure as a Service (IaaS) –you rent the infrastructure, as a service. An example is Amazon Elastic Cloud Compute (EC2) Platform as a Service (Paas) –programming platforms and tools, building blocks and APIs for building cloud-based applications and services –Amazon Simple Storage Service (S3), Azure Storage, and Force.com Software as a Service (SaaS) –Applications are exposed as a service running on a cloud infrastructure –SalesForce.com and Microsoft Office Online 6 a-service-iaas.aspx

7 University of Southern California Center for Systems and Software Engineering Why is SSME important? The world is becoming networked, dependent on information and information technology Science will provide tools and methods to study services and develop solutions to problems that span multiple disciplines Graduates may be solution designers, consultants, engineers, scientists, and managers who will grow into becoming entrepreneurs, executives, researchers, and practitioners © Copyright IBM Corporation 2006, All rights reserved.

16 University of Southern California Center for Systems and Software Engineering The War Between Google, Amazon, Facebook, Apple Old days –Amazon sold books, Google was a search engine, Facebook was a social network and Apple sold computers. Now –Google and Apple now sell phones. –Amazon has gotten into the server business. –Apple sells music. –Facebook and Amazon provide online payment services 16

17 University of Southern California Center for Systems and Software Engineering Amazon's business model Something smarter than iPad –Less powerful on purpose –Kindle Fire is smaller than the iPad and cheaper –Very intimately tied to Amazon's Web store –No profit from the device, but from the store 17

18 University of Southern California Center for Systems and Software Engineering Google's business model Beyond search Online stores — a bookstore, a new music service Android - very successful mobile operating system Google self-driving cars –Short-term / long-term innovation Google+ –Compete with Facebook billion people big advertising opportunities 18

19 University of Southern California Center for Systems and Software Engineering Facebook's business model Has all the data Gigantic valuable advertising opportunities An application for iPhone and Android phones –allows customers to text-message with each other and bypass the cell phone text-messaging system a lot more of those kinds of apps in the future 19

20 University of Southern California Center for Systems and Software Engineering Apple’s business model Apple has integrated Twitter throughout iOS 5, letting you tweet from any app Apple makes a significant profit on every device it sells, while Google and many Android handset makers do not. Apple-branded television set 20

21 University of Southern California Center for Systems and Software Engineering Economic Potential of SOA investments in SOA-based, flexible information technology (IT) infrastructures enable firms to derive greater value from collaborative joint ventures SOA adds value by addressing the four major architecture challenges –application integration –value reconfiguration processes –value preservation after mergers and acquisitions –more agile forms of IS development 21 Mueller, et.al, Understanding the Economic Potential of Service-Oriented Architecture, JMIS, Spring 2010

22 University of Southern California Center for Systems and Software Engineering Economic Potential of SOA SOA enhances architectural extensibility –providing potential for greater organizational agility and competitiveness SOA adoption –(1) as a standardized integration infrastructure, SOA decreases overall system integration costs –(2) SOA reduces enterprise-wide IT costs and decreases IT projects’ time-to-market with regard to decoupling application domains –(3) SOA improves IS support for end users regarding flexible user/business process integration 22 Mueller, et.al, Understanding the Economic Potential of Service-Oriented Architecture, JMIS, Spring 2010
