Introduction to Jazz Architecture 2

Agenda and Objectives

We will cover:

Jazz Objectives

Jazz Platform Architecture

Jazz Platform Extensibility

Future thoughts. Were not done yet


3/27



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


4/27



Think differently

Current approaches for building tools dont gofar enough

"We can't solve problems by using the same kind

of thinking we used when we created them."

A. Einstein


5/27



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

Jazz Server Kernel

Team Repository Services

Provides the basics for

querying, fetching, andupdating repository data

Provides a platform for extensibleAJAX Web UIs

Provides support for changeevents and feed rendering

Provides access to and managescomponent services

Process component. Provides:

projects, teams,

and process.

Runs in an OSGI environment

You can create a process awareservices that enables itself tobe governed by process.

Jazz Platform - Service programming model

Its stateless services all the way down

Services are contributed by bundles

Statelessness is key to scalability

All state is in the DB, all client interactionsare atomic

Clusterable and restartable

No session state (clients are stateful)

Jazz Platform repository data modelthree logical DBs in one

An open-ended item store

Stores structured items as XML

Stores arbitrary content as BLOBs

A declarative indexing story to support query

Lucene text index to support full-text search

A snapshot framework for extracting summarydata for reporting

Process basics

Teams work on projects

Each project follows a process

Work inside the scope of a team follows the teams process

Team members play roles defined by the process

Process manifests itself through artifacts types, operations manipulating the

artifacts, and artifact change events


14/27



Configurability through Process

Allows team specific work products and behavior

Allows team specific conditions under which client-side and server-side

operations are allowed to proceed

Allows team specific participants for client-side and server-side operations

Allows team specific reactions to server-side change events

The Jazz Platform itself is artifact and process neutral

Its the components that explicitly introduce the specifics of process configuration

Example: Finding the Right Process (the Jazz Process)1 Jazz Project area defines process

2 Jazz team area does not customize the process

3 Process team area customizes the process

Myth: Developers hate process.

Truth: Developers are ok with process if they defined itand it helps them get their work done.

Extensibility of the Jazz Platform


18/27



The Jazz SDK and Jazz Labs

Two evolving sources of information for Jazz extenders on Jazz.net

SDK is the primary source, the essential stories for extending the platform (wiki RtcSdk)Jazz Labs is more experimental (wiki JazzLabs)

Client Applications

Jazz Client Kernel

Provides access to and manages repository connections

Provides the basics for querying, fetching, and caching repository data

Provides access to and manages feed subscriptions and feed data

Provided access to and manages client libraries

Provides the notions of projects, teams, and process

Runs in OSGI environments such as eclipse RCP and in plain java clients

Jazz UI Foundation

Java Client

Jazz Client Kernel


21/27



Plain Java Extension

It is a normal plain Java application

Establishes one or more connections to Jazz repositories

Uses (and provides) client libraries

TeamPlatform.startup();

ITeamRepositoryServicesrv =TeamPlatform.getTeamRepositoryService();

ITeamRepositoryrepo =srv.getTeamRepository(myRepositoryURL);

repo.login(progressMonitor);

IQueryClient qryClnt =repository.getClientLibrary(IQueryClient.class);

IQueryResult result= qryClnt.findAll(myQueryExpression);

processWorkItems(result);


Java Client

Jazz Client Kernel


22/27



What are Client Libraries?

A bundle that provides a sophisticated faade for a components functionality

A service running on the Jazz Team server

Looks like youre just invoking client side Java API

Hides complexity of transport

Instantiated only once per repository connection

may have state and allow for listeners

Talks to Jazz platform and component specific services on the server

Can leverage smart, optimized communication patterns

Manages the caching of the components repository data

Can depend on and talk to other client libraries

Interesting client side applications are possible by using the Jazz Client Kernel andexisting client libraries


23/27



Other key extensibility stories for RTC 1.0

Create a new report

Use the BIRT report editor and the RTC data warehouse schema to provide custom

reporting (sample reports provided)

Extending the Build system

Templates driving Ant based builds provided.

Provide a new build template, e.g. Maven support

Create a new process template

Process component provides XML schema for templates

Includes process-specific work item types, supporting reports, process guidance

Templates are then used to launch projects using that template

See examples in RTC

JRS Experiment: Implement tools like an internet application

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 structuredindexes, independent

Standard analysis, query, reporting

HTTP GET/PUT/POST/DELETE

Index

Programming model

Specified in Open ServicesFor Lifecycle collaboration


26/27



Summary: Ongoing Architectural Innovation

The Jazz Platform is the plumbing inside Rational Team Concert 1.0 product

The platform and products built on it are open to extensibility, Jazz.net wiki will bethe place to go for details

The Jazz Core team continues to innovate on the Platform, improving

Capability

Scalability

Configurability

Connectivity
