galaxy, an open SOA R&D platformenabling agility

Open• An open internal and multidisciplinary collaboration

• Software development, under open source licensing model

– Relationships with open source communities Eclipse, OW2 Local Chapter Europe

SOA (Service-Oriented Architecture)

ADT galaxy (SOA)



SOA (Service-Oriented Architecture)• A paradigm facilitating collaboration b/w several teams and expertise

• A coherent set of technologies developed by INRIA

• A personality and a visibility for INRIA technologies

An assembly and integration based on agility features• Interactions design / runtime

• Interactions multi-layers

Agility, what for ?Agility, what for ?

Build an end-to-end SOA approach

Unify your components, services and processes• From designing a process to executing component assemblies through an composite application architecture (SCA-compliant)

Dynamically orchestrate your services•

ADT galaxy (SOA)



• Agile distribution of a BPEL execution

Get benefits from highly adaptable & dynamic architectures• A modular conception of systems with native reconfiguration features (Fractal)

• A standard programming model for distributed systems (GCM, ETSI)

• Agile QoS-based reconfiguration features

12Licensing analysis activities

Analysis of the problem with open source licenses in galaxy

• « Licenses IN »– Different licensing models (LGPL, GPL, EPL, …)

• Usage analysis in galaxy– Assembly and integration of different components

– Internal / External– Outputs and valorization

• « Licenses OUT »– Choose the appropriate license mode

Guidelines

ADT galaxy (SOA)



Guidelines• « Gather licenses in your project »• « Beyond the life time project »• « Dissemination »• « Documentation license policy »• « Conflict audit »

Interactions with the INRIA’s Transfer & Innovation Direction• Experimentation of FOSSOLOGY software

13galaxy, technologies & integration

Some technologies & standards

• OW2 (Fractal-based)• FraSCAti• FPath / FScript• GCM/ProActive• WildCAT

• Eclipse: SOA Tooling Platform• STP-IM, Intermediate Model

• New pieces

ADT galaxy (SOA)



• New pieces– SOA Monitoring framework

• BPMN, BPEL, SCA, GCM

Some integration scenarios• “From design to runtime”• “Dynamic service execution”• “QoS provisioning”

First integration and demonstrations• JavaOne 2009, June 2009

galaxy, potential outcomes

Collaborations with open-source platforms (OW2, Eclipse)

• Eclipse SOA Platform (new « Top Level project », leader Sopera)

Collaborations with specific application domains & platforms

• INRIA’s experimentation platform – e.g.: SensLAB, SensTOOLS

• RFID Systems – OW2 RFID Aspire

• Cloud Services & SaaS (Orange Labs)

ADT galaxy (SOA)



• Cloud Services & SaaS (Orange Labs)

• IS Platform for innovative production systems (cluster GOSPI Rhône-Alpes)

Collaborations with INRIA DTI

• Technological & business maturation, transfer

• Analysis and definition of the licensing model

• Discussions with «innovation hunters » (software editor & embedded, sustainable development)

OW2 technologies

ADT galaxy (SOA)



17

FraSCAti = SCA++(frascati.ow2.org)

FraSCAti :• A Java SCA Platform

SCA :• Joint OSOA / OASIS specification

FraSCAti : OW2 project

Extend SCA with additional features• Dynamic deployment

ADT galaxy (SOA)



• Dynamic deployment & configuration• Runtime adaptation& reconfiguration• Reconfiguration of SCA components & FraSCAti itself

Build on top of a number of existing INRIA OW2 technologies• Fractal, FDF

18

FPath and Fscript overviewDynamic and reliable reconfigurations

(http://fractal.ow2.org/fscript)

Two Domain-Specific Languages (DSLs) dedicated to Fractal• FPath: navigation, introspection and selection of Fractal components

• FScript: run-time reconfigurations of Fractal architectures

Properties of DSLs• focus on the manipulation of architecture-level concepts

• offer a very concise and readable syntax

ADT galaxy (SOA)



• offer a very concise and readable syntax

• ensure correctness properties by construction

– e.g. any query terminates in a finite time (FPath)

– e.g. termination of scripts by excluding the possibility of infinite loops (FScript)

A run-time support for fault-tolerance (i.e. safe reconfigurations)• FScript reconfigurations are performed using a transactional model

– automatic and transparent error detection

– rollback the invalid reconfiguration

• preserve ACID properties

19SCA and GCM components(proactive.ow2.org)

• SCA personality for GCM components

• SCA bindings between FraSCAti components and GCM components through web services

• Convergence of FraSCAti and GCM tools

=> Result in a SCA full-fledged SOA application, including Grid-aware SCA components

ADT galaxy (SOA)



aware SCA components

20

WildCAT in a nutshell(wildcat.ow2.org)

Generic and extensible framework for context-aware applications

Hierarchical organisation of probes• Analogy with Unix-like file system

• Everything is dynamic

Support for both ways for querying result• Synchronous API (pull mode)

•

ADT galaxy (SOA)



• Publish/subscribe API (push mode)

Support for distributed communication (RMI and/or JMS)

Based on Esper: an open-source Complex Event Processing (CEP) engine

• Logical and temporal event correlation

• Grouping, aggregation, sorting, filtering and merging of event streams

• Sliding windows: time, length, sorted, accumulating, time-ordering

21

Eclipse technologies

ADT galaxy (SOA)



22

Intermediate Model Overview(http://www.eclipse.org/stp/im)

Bridges different SOA platforms in STP• Workflow / process: e.g. BPMN, BPEL

• Architecture specification: e.g. SCA, EID, JBI

• Service Creation: e.g. JAX-WS, Policy Specification

Facilitates interoperability between editors• Provides a central SOA conceptual bridge

•

ADT galaxy (SOA)



• Provides a central SOA conceptual bridge

• Avoids duplication of data

• Minimizes amount of transformation code

• Facilitates code generation from a variety of sources

Initial Contribution: INRIA (FR) and Engineering (IT)• STP component: org.eclipse.stp.model

• EMF model plugins + transformation plugins

• Used in the Spagic 2.0 SOA Suite from Engineering
