  4. C1 C2 Implementations C3 C4 A1 A2 Component elements • Components consist of: • Interface • Inputs, outputs, ports, attributes • Configuration options • Local tailoring Provided by COTS component implementer: • Implementation(s) • One or more implementations per component, possibly from different vendors • Deployment requirements/constraints • Platform, environment, etc. A5 A6 A4 A3

  5. COTS Component Market Requirements Developing a viable COTS component market requires two key aspects to be addressed: • Component • Industry agreed interfaces (APIs, protocols, configurations) • Industry standards for describing components and component artefacts • Deployment framework • Infrastructure services • Management of deployment, runtime components, etc. • Industry standards for describing platforms • Descriptor files required for: • Application/component • Deployment platform • Deployment plan

  6. C1 C2 Component-Based Application Application Engineer C3 C4 Descriptor Files (XML) Problem: Descriptor Generation • Conventional UML tools • VISIO Application Validation ? • Manual • Labor intensive • Error prone

  7. Currently To build a new application, an Application Engineer must: • Assemble and configure components • Validate component configurations and assemblies • Create the descriptor files to deploy • Validate the descriptor files Issues • The work is very labor intensive and error prone • It requires highly-skilled engineers • As the number of components and application complexity increase, application maintenance will become extremely difficult and costly

  8. C1 C2 Component-Based Application Application Engineer C3 C4 Descriptor Files (XML) Solution: Automatic generation and validation Application Validation? Automated

  9. Industry Standards Deployment and Configuration Standards are defined within the context of a component framework: • J2EE and .NET • CORBA Component Model • OMG Deployment and Configuration Standard • Domain specific standards • Software Defined Radio (SCA) • Automotive Open System Architecture (AUTOSAR)

  10. Questions • Technical issues? • Definition of concrete deployment platforms • Appropriate Deployment and Configuration standards • Business issues? • Industry buy-in • Standards processes • Development approaches? • UML and MDA • Tool support
