Tech. Works IBM Software Group | Rational software What is SOA Quality Management? SOA Quality Management is the process to assure services meet business requirements by validating service functionality and operations throughout the SOA Lifecycle ife SOA L SOA Quality Management is continuous and takes place within each phase of the SOA Lifecycle 5

Tech. Works IBM Software Group | Rational software The SOA Testing Strategy § The only way to effectively test SOA projects is to…. 4 start from the ground up. 4 test the inputs and outputs of individual modules. 4 assemble sections of logic together and test smaller sections of the integration flow. 4 Assemble those smaller sections into a finished SOA project and perform an end-to-end test on the fully assembled project. § Key tenants 4 Focus on the business processes in requirements and testing 4 Create test plans that account for assembly of services 4 Create an automated and repeatable testing process 4 Plan for typical SOA testing hurdles (e. g. security access, unavailable systems) Test early, test often is more important now than ever (due to the domino affect a bug in a service may have on a given business process and the possibility of that service being in many business processes) 6

Tech. Works IBM Software Group | Rational software SOA adoption increases modularity & change Bringing quality to the forefront Pain of modularity Business impact § Lower level of functionality & performance both at individual service level & composite application § Service and application SLAs will be impacted by more frequent updates § Increased risk and need to manage distributed assets § Cross-organization Business/IT organizations will have increased complexity § Increased management of a larger number of services including custom, outsourced & packaged Decentralization, modularity and increased risk drives need for a structured approach of integrated requirements, architecture & lifecycle quality management 8

Quality Management of Service Oriented Architecture Applications The IBM Rational Solution is a three pronged approach § Traditional user centric requirement, test and defect management § New Web Service Quality functionality to address building blocks of SOA Apps § Post Deployment monitoring of service oriented architecture applications 11

Tech. Works IBM Software Group | Rational software Challenge: The Cost - Time - Quality Tradeoff Governance of the software delivery process Your job is to deliver quality applications. On Time. On Budget. You need to coordinate teams, data, schedules, requirements, models, code, tests, results and reports. Are you ready? “Everyone uses different tools – there’s no way to share data between the team. ” “I have requirements, I have tests and I have defects…but nothing ties them together” “There’s too much to test. Where do we begin ? ” 12

Tech. Works IBM Software Group | Rational software Challenge: Validating SOA component functionality & performance Ensuring functionality of composite application units Web Services are the building blocks of SOA applications. A single service is a standalone component but may be used in dozens of systems. Some of those services will be yours, some not. How do you test a service without the rest of the system? Does it work? All the time? Under load? Are you sure? “The Web Service is ready for testing, but there is no user interface to exercise it. ” “We don’t want to pull Programmers off their projects to write complex test harnesses. ” “How can we leverage our Business Process analysis in our services testing efforts? ” 13

Tech. Works IBM Software Group | Rational software Challenge: Post Deployment Monitoring of Services Creating a feedback loop from operations to development Congratulations you’ve gone live. How are things going out there? Do you know? What happens when you need to make a change? And what if operations found a problem – how would it get back to development? Do these groups communicate? “How can I monitor web services running on many different platforms against thousands of users? ” “How do I change policies and ensure those changes don’t break the implementations? ” “How can I communicate problems found in the field back to development? ” 14

Tech. Works IBM Software Group | Rational software Service (in the context of SOA) § A self contained business function in which consumers interact through a well defined interface (contract). § The consumer does not know (or care) "how" the service implements the requested business action - only that the service performs "what" is defined by its published interface (contract). A service in the context of an SOA An abstracted view of SOA concepts 22

Tech. Works IBM Software Group | Rational software WSDL – Web Service Description Language § An XML-based service description on how to communicate using web services. § Defines services as collections of network endpoints, or ports. § Specification provides an XML format. § The abstract definition of ports and messages is separated from their concrete use or instance, allowing the reuse of these definitions. § WSDL is often used in combination with SOAP and XML Schema to provide web services over the Internet. 23
