  1. BUSINESS PLUG-IN B17 Organizational Architecture Trends

  2. 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

  3. LEARNING OUTCOMES • Identify the logical functions used in a virtualized environment • Explain the business benefits of grid computing

  4. 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

  5. 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

  6. SERVICE ORIENTED ARCHITECTURE

  7. SOA Business Benefits • The key technical concepts of SOA are: • Services • Interoperability • Loose coupling

  8. SOA Business Benefits

  9. 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

  10. Service

  11. 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) - amarkup language for documents containing structured information

  12. Loose Coupling • Loose coupling - is the capability of services to be joined together on demand to create composite services, or disassembled just as easily into their functional components • Loose coupling is a way of ensuring that the technical details are decoupled from the service

  13. VIRTUALIZATION • Virtualization - is a framework of dividing the resources of a computer into multiple execution environments • It is a way of increasing physical resources to maximize the investment in hardware

  14. VIRTUALIZATION

  15. What are Virtual Machines? • System virtualization - is the ability to present the resources of a single computer as if it is a collection of separate computers ("virtual machines") • Each with its own virtual CPUs, network interfaces, storage, and operating system

  16. What are Virtual Machines?

  17. Virtualization Business Benefits • Trends that have moved virtualization into the spotlight: • Hardware being underutilized • Data centers running out of space • Increased energy costs • System administration costs mounting

  18. Additional Virtualization Benefits • Rapid application deployment • Dynamic load balancing • Streamlined disaster recovery

  19. GRID COMPUTING • Grid computing - is an aggregation of geographically dispersed computing, storage, and network resources, coordinated to deliver improved performance, higher quality of service, better utilization, and easier access to data

  20. GRID COMPUTING

  21. Grid Computing Business Benefits • Improving productivity and collaboration of virtual organizations and respective computing and data resources • Allowing widely dispersed departments and businesses to create virtual organizations to share data and resources • Building robust and infinitely flexible and resilient operational architectures

  22. Grid Computing Business Benefit • Providing instantaneous access to massive computing and data resources • Leveraging existing capital investments, which in turn help to ensure optimal utilization and costs of computing capabilities

  23. Grid Computing Business Benefits

  24. CLOSING CASE ONEThe US Open Supports SOA • Review the five characteristics of infrastructure architecture and rank them in order of their potential impact on the USOpen.org • What are the USTA security concerns regarding interoperability between the tournament database and its website? • How could the USTA benefit from virtualization?

  25. CLOSING CASE ONEThe US Open Supports SOA • Identify the value of integrating the tournaments information with the USTA website USOpen.org? • Explain why a sudden surge in server utilization during the middle of the US Open could spell disaster for the USTA • Why is loose coupling a critical business component to the USTA architecture?

  26. CLOSING CASE TWOeBay’s Grid • Review the five characteristics of infrastructure architecture and rank them in order of their potential impact on eBay’s business • What are the business benefits that eBay enjoys thanks to grid computing? • What precautions would eBay take to ensure 100 percent security?

  27. CLOSING CASE TWOeBay’s Grid • How can eBay take advantage of implementing SOA? • Explain how eBay uses fault tolerance • Describe the potential value of eBay using virtualization • What ethical and security concerns should eBay be aware of to ensure its business operates properly?
