In this chapter students will be able to: Describe the business value in deploying a service oriented architecture, explain the need for interoperability and loose coupling in building today’s IT systems, identify the logical functions used in a virtualized environment, explain the business benefits of grid computing. | BUSINESS PLUG-IN B17 Organizational Architecture Trends LEARNING OUTCOMES Describe the business value in deploying a service oriented architecture Explain the need for interoperability and loose coupling in building today’s IT systems LEARNING OUTCOMES Identify the logical functions used in a virtualized environment Explain the business benefits of grid computing ARCHITECTURE TRENDS Organizations today must continually watch new architecture trends to ensure they can keep up with new and disruptive technologies Three architecture trends that are quickly becoming requirements for all businesses including: Service oriented architecture Virtualization Grid computing SERVICE ORIENTED ARCHITECTURE Service oriented architecture (SOA) is a business-driven IT architectural approach that supports integrating a business as linked, repeatable tasks or services SOA ensures IT systems can adapt quickly, easily, and economically to support rapidly changing business needs SERVICE | BUSINESS PLUG-IN B17 Organizational Architecture Trends LEARNING OUTCOMES Describe the business value in deploying a service oriented architecture Explain the need for interoperability and loose coupling in building today’s IT systems LEARNING OUTCOMES Identify the logical functions used in a virtualized environment Explain the business benefits of grid computing ARCHITECTURE TRENDS Organizations today must continually watch new architecture trends to ensure they can keep up with new and disruptive technologies Three architecture trends that are quickly becoming requirements for all businesses including: Service oriented architecture Virtualization Grid computing SERVICE ORIENTED ARCHITECTURE Service oriented architecture (SOA) is a business-driven IT architectural approach that supports integrating a business as linked, repeatable tasks or services SOA ensures IT systems can adapt quickly, easily, and economically to support rapidly changing business needs SERVICE ORIENTED ARCHITECTURE SOA Business Benefits The key technical concepts of SOA are: Services Interoperability Loose coupling SOA Business Benefits Service Service oriented architecture begins with a service (A SOA) service - can be a business task, such as checking a potential customer's credit rating only opening a new account Services are “like” software products Service Interoperability Interoperability - is the capability of two or more computer systems to share data and resources, even though they are made by different manufacturers Web service - contains a repertoire of Web-based data and procedural resources that use shared protocols and standards permitting different applications to share data and services Extensible Markup Language (XML) - a markup language for documents containing structured information Loose Coupling Loose coupling - is the capability of services to be joined together on demand to create composite services, or disassembled just as .
