4. EasySOA - Factsheet
EasySOA Facts
– 5 partners
– 2 years, started nov. 2010
– 4m€ budget
– System@tic label
– And an ambitious aim…
Making Service Oriented Architectures (SOA) simple to use
– Business use, development, production use, monitoring
– And throttling up the SOA engine in the entreprise !

5. EasySOA - Goal

6. EasySOA - Goal
Add a lighter, agile SOA layer around “traditional” SOA
• thanks to an online, social and collaborative approach,
involving all actors of the SOA process
– business users, SOA architects and developers, IT staff
• Enabling
– ex nihilo service discovery, cartography and documentation, all
collaboratively
– sanitization and protection of existing SOAs by tracking changes of
outside services
– help gathering and fast-prototyping business needs on top of
existing applications, without hurting them
– reuse requirements, architectural shell, tests and mockups to ease
the transition to final implementations within the existing SOA
solution

7. EasySOA – Consortium
Behind, French partners but also worldwide leaders
• INRIA labs : service engine (OW2 FraSCAti)
• EasiFab : SOA Modeling (Eclipse SOA), monitoring (Galaxy)
• Talend (ETL/ESB) : SOA and data connectors to connect to
existing business – but also Data Quality and MDM
• Nuxeo (ECM) : document management platform, to manage
the SOA model, documents and artifacts
• Bull (service provider and middleware) : SOA administration
with OW2 Jasmine and use case
• Open Wide : leader, global architecture and integration,
BPM (with Eclipse JWT / OW2 Scarbo), use case

8. Business users… and services ?!
SOA is not only for technical people ! Business users
• are not interested in services on a technical point of view , but
in how they impact business features, ex. :
– Which service failure cause a feature to be down
– Allow to evolve or develop new features
• On the other side, business users have the knowledge
– on business needs, business data and how they map…
• most business users would like to have better visibility on how
IT answers (or not) their business needs !
– No more “IT as a black box”
– Up to the business alignment of IT. SOA is a mean to this end !

9. EasySOA Core & Light
EasySOA Core is just the place for that :
• Rather than a formal, constrained, heavy process, provide the
tools and the place for informal, social collaboration
– Around services and information about it (how they’re used & made…)
– Between all SOA actors, with each its own point of view and knowledge
And that for the most technically savvy of them, even
• Allows mockups, mashups and prototyping,
• in a sandboxed and monitored manner : EasySOA Light
• i.e. an embedded custom-tailored scripting and ESB platform

10. EasySOA Core & Light
EasySOA Core is just the place for that :
• Rather than a formal, constrained, heavy process, provide the
tools and the place for informal, social collaboration
– Around services and information about it (how they’re used & made…)
– Between all SOA actors, with each its own point of view and knowledge
=> OW2 Nuxeo
And that for the most technically savvy of them, even
• Allows mockups, mashups and prototyping,
• in a sandboxed and monitored manner : EasySOA Light
• i.e. an embedded custom-tailored scripting and ESB platform
=> OW2 FraSCAti

11. Why OW2 Nuxeo as Service Registry
SOA is actually first about documenting services
• Listing them & their definitions, specifications, uses, lifecycle
For EasySOA Core, we've chosen OW2 Nuxeo
• Collaborative document management platform with :
• extensible model
• Document classification : folders, relations, virtual trees
• collaborative platform : comments, workflows
• Access : customizable UI, REST web engine, Content
Automation, CMIS, Talend (upcoming)

12. Why OW2 FraSCAti for Light platform
For EasySOA Light, we've chosen OW2 FraSCAti
• model using SCA standard
– What are the services, and what other services do they need to work
(kind of remote service dependencies injection)
– so can describe any possibly existing SOA
• middleware of middlewares, so will handle all
– protocols (WS, REST, JMS),
– languages (Java, script)
– frameworks (OSGi, Spring)
• and lately, in part because of EasySOA, towards
– scripting, modularity, Cloud

13. EasySOA – Architecture

14. FraSCAti in Nuxeo – how
2 platforms integrating the whole world !
• Al lot (100+) conflicting dependencies
• SCA composite parsing works well, starting not so
Some good news
• Happily both are getting OSGi-fied, already partly there
• Emerging, Nuxeo-free EasySOA API
=> Start (parts of) FraSCAti
Nuxeo
within an OSGi kernel
started within Nuxeo Felix FraSCAti : EasySOA
(INRIA using a Nuxeo OSGi WS / CXF API on
kernel Web / Servlet… Nuxeo
pattern)

15. FraSCAti in Nuxeo – for what
OW2 FraSCAti for Light
• “Proxies” :
– Simple Service Scaffolder client,
– Fuse SLA proxy,
– Service discovery by monitoring exchanges using HTTP proxy…
• Service discovery from SCA
• FraSCAti Studio (in the works)
13/12/2011 15

16. OW2 FraSCAti for Light : Discovery
Service discovery by architecture import
• Had been first implemented by parsing SCA as XML
By getting FraSCAti in more and more, we allowed for 3
use cases :
• The same but with full error checking
– by parsing using an embedded FraSCAti instead (BindingInfoProvider)
• Service discovery at startup of remote FraSCAti runtime
– by replacing going from local to remote EasySOA API and hooking SCA
import mechanism within FraSCAti (BindingScaVisitor)
• The same but for Light, so within Nuxeo,
– thanks to modularity & OSGi (in the works)

17. « Light » service sandbox dev scenario
Goal : To add a business-layer above an existing service.
Let EasySOA protect
this service behind a
sandboxing tunnel.
Design Discover Toolify Develop Release
Find the existing a. Develop our business-
service we want to use. oriented service.
b. Create a Service
Scaffolder UI to use it.

23. And with a “classical” SOA solution ? Enter
Talend ESB !
Easily integrate distributed systems
 Standards-based connectivity layer to integrate
distributed systems
 Powered by Apache CXF, Camel, Karaf and
ActiveMQ
 Includes messaging, Web services,
intelligent routing, failover, monitoring and security
Talend ESB Studio
 Quickly and easily create data
services and complex message routes
without coding
 Leverage existing skillsets with
Eclipse-based UI
 Drag-and-drop message routes using
Enterprise Integration Patterns (EIPs)

24. Talend ESB with EasySOA Core & Light

25. EasySOA – Entreprise Partner Program
A « from the trenches », « guerilla » approach
• To help gather recurring use cases and needs, around the
project core, at our clients’, our communities
• People we know, who trust us, that we ask to share their
SOA issues
The idea : reciprocal sharing
• Share your issues with us,
• We’ll enrich EasySOA to address the most promising and
useful ones, and share our developments back in Open
Source
Pay only custom work
• If you want some : install, config, custom devs
25

26. Roadmap
Halfway there ! Still :
– API change detection (Partner X)
– SOA documentation (Partner Y)
– light cloud application platform (Partner Z)
– More EasySOA API
– More Light : FraSCAti Studio & on demand Proxies
for recording, testing, prototyping…
– BPM with OW2 Scarbo, monitoring with OW2
Jasmine
