1 IBM Rational Software Development Conference 2008 Introduction to the Jazz Technology Platform: Architecture Overview and Extensibility Scott Rich Distinguished Engineer, Jazz Architect IBM Rational SDP21

2 Agenda and Objectives Disclaimer: this is an introduction to some deep technical topics, not an introductory talk We will cover: Jazz Objectives Jazz Platform Architecture Jazz Platform Extensibility We re not done yet SDP21 2

3 Objectives/Architecture Requirements No boundaries between people Data and tasks from one tool are seamlessly visible in others Creative Collaboration across geography and organization Tools live the process Capability is strong but unobtrusive Support wide range of configurations Need modular, composable solution Stay flexible SDP21 3

4 Think differently Current approaches for building tools don t go far enough "We can't solve problems by using the same kind of thinking we used when we created them." A. Einstein SDP21 4

5 Think differently Desktop/Database Integration Global Integration Function First Team First Manual Process Aware & Transparent Pre-determined Tool Function Dynamically Extensible Proprietary infrastructure Internet Standards Rigid Process Creative Collaboration SDP21 5

6 Jazz Architecture Eclipse Client Platform Web Client Platform Visual Studio Client Platform Project and Team Structure Event Notification Process Enactment Jazz Team Server Storage Security and Access Query Search Defects Requirements Use-cases,.. Jazz Repository Items and relationships Event history, Item history trends.,builds Source code, Test-cases Test results SDP21 6

7 Extending the Jazz Platform Understanding jazz.war App Server /jazz/* Jazz.war Jazz Server Provisioner Equinox Framework /jazz/service/*../iworkitemservice../ifilesystemservice../iplanrestservice /jazz/web/*../workitemview.js../planview.js Equinox Bridge Servlet Team Services Team Web WorkItem Services Planning Services WorkItem Web Planning Web SCM Services SDP21 7

8 Jazz Server Kernel Team Repository Services Provides the basics for querying, fetching, and updating repository data Provides a platform for extensible AJAX Web UIs Provides support for change events and feed rendering Provides access to and manages component services Provides the notions of projects, teams, and process Runs in an OSGI environment Web UI Jazz Team Server Jazz Server Extensions Jazz Server Kernel Eclipse Equinox Container (Jetty, Tomcat, WAS) SDP21 8

9 Extending the platform - Service programming model It s stateless services all the way down Services are contributed by bundles Statelessness is key to scalability All state is in the DB, all client interactions are atomic Clusterable and restartable No session state (clients are stateful) SDP21 S 9

10 Extending the Jazz Platform repository data model three DBs in one A declarative indexing story to support query An open-ended item store Stores structured items as XML Stores arbitrary content as BLOBs Lucene to support full-text search A snapshot framework for extracting summary data for reporting Operational DB Item store (private) indexer Index data (queriable) extractor Data Warehouse (public) Data warehouse DB SDP21 S 10

11 Simple Jazz Team Server Administration SDP21 11

12 Authentication and Permissions App Server Authentication Corporate Directory server LDAP import Jazz Team server Repository Permissions: (Managed by IT) -Admin -Writer -Reader Process Permissions - team-managed - role-based - dynamic Repo DB SDP21 12

13 Process basics Teams work on projects Each project follows a process Work inside the scope of a team follows the team s process Team members play roles defined by the process Learn more at SDP27: Wednesday, 11:15 Process manifests itself through artifacts types, operations manipulating the artifacts, and artifact change events SDP21 13

14 Finding the Right Process 1 Jazz Project area defines process 2 Jazz team area does not customize the process 3 Process team area customizes the process SDP21 14

15 Process Execution Flow Client Server Component Process Component Process Client Request Handle Request Preconditions Permissions Server Request Preconditions Permissions Handle Request Follow-ups Request Response + Process Reports Follow-ups Process Hints Enforced Process Rules SDP21 15

16 What we learned Jazz Platform 0.6 provides a fully general server-side programming model Wire protocol is implementation, clients program to Java client libraries Resources modelled; serialized between client and server Clients communicate using RPC style interface Currently exploring providing a simpler programming model Provide an on-ramp to ease extensibility Characteristics of experiment Wire protocol is API, accessible to clients of all kinds Resource representations explicitly specified Clients communicate using RESTful interface More declarative building blocks SDP21 16

17 Experiment: Implement tools like an internet application HTTP GET/PUT/POST/DELETE Index Build on Jazz experiences in Web UI Data specified independently of tools All data are resources with URLs Ubiquitous access Tools access data through HTTP/APP Multiple tools same data Data integration without forcing same tool for multiple roles References are embedded URLs Cross technology/location Resources have representations XML encouraged, not required Search and query through structured indexes, independent Standard analysis, query, reporting SDP21 17

18 Summary: Ongoing Architectural Innovation The Jazz Platform is the plumbing inside every Rational Team Concert The Jazz Core team continues to innovate on the Platform, improving Capability Scalability Configurability Connectivity SDP21 18
