4. SOA – STATE OF THE ART
Information Systems, getting open and interconnected…
Growing awareness in IT departments
Democratization of message and data exchanges
Acknowledgement of architectural best practices
…however…
SOA projects are complex
► Different actors with various concerns & profiles (Business vs Technical)
► Technology heterogeneity (risk management)
► Different partners (internal vs external services)
► Not much knowledge sharing on how things are done Exigences
Besoins d’‛exploitatio
Métier Contraintes n
SOA needs are not always well understood de
réalisation
► A lot of services have been forgotten and are
waiting to be woken up
► New needs : Cloud, Mobility Open Wide Technologies 4

5. EASYSOA
An SOA governance administration solution
A critical tool for Information System Architects…
…to keep business process consistency in check…
…all while maintaining service lifecycle management…

8. EASYSOA – GOALS
To ease up SOA governance…
Add a lighter, non-intrusive layer over « traditional » SOA in order
to provide governance overview
Keep changes to a minimum on existing services and applications
while maximizing extracted value (documentation, practices, uses)
Service quality analysis for SOA sanitization
Agile approach through extracted as well as collaborative
documentation and prototyping
Fosters emergence and evaluation of best and most urgent needs
to be implemented next using existing « traditional » SOA
Version management and impact analysis of service changes
(internal or external) on business processes
…to secure and optimize exchanges between services of
Open Wide Technologies 8
the enterprise and its partners

9. THE EASYSOA PLATFORM
A light, non-intrusive solution
An additional, non-intrusive layer over the enterprise’s
SOA allowing for Web tools that ease up gathering and
analysis of existing services, as well as developing simple
new services using scripting, RAD or Point-and-Click.
A consistent multimedia registry aggregating all
Light SOA information, coming from automated extraction
as well as manual input by SOA actors, in a Document
Management (DM) solution and its indexed database,
Core
enabling easy high volume information management
through the Web.
Integration
An ecosystem of solutions and extensions
allowing for compatibility with a large range of
« traditional » SOA architectures to further
« Traditional » SOA
Middleware empower them : business process modeling
architecture
and execution, monitoring…
The enterprise’s SOA architecture, built on
« traditional » and well-known solutions is not
impacted by using EasySOA

12. USE CASE
ANCV (National Agency for Holiday Vouchers)
Two different businesses, done by separate departments,
each with its own Information System (IS)
► Selling holiday vouchers, by the DCV entity
► Funding holidays for underpriviledged people, by the DPS entity
DPS has now decided for its IS to go beyond spreadsheets
► This use case is the real story of DPS IT being built from the ground
up, rewritten with EasySOA Registry, Talend ESB and OW2 Jasmine.
Existing applications
► SI DCV – Pivotal : management of ANCV social partners. Customized
MS .NET web CRM.
► Uniserv : online address checking service
New applications : SI DPS – APV
► Management of « holiday projects ». subcontracted Java web
business application. Has to connect with Pivotal, using Open Wide Technologies
services. 12

How to provide checked information from Pivotal to APV ?
Simple: some service plumbing between both and Uniserv!
But how to separate ITs share (in)formal specifications? Design them
together without over-meeting? With each having its own point of view?
How to set them in stone, and still handle (unavoidable) changes?
How to best share knowledge about what is being developed, so one
team can easily use and test what the other did?
How to be sure that everything that should be developed and provided
has been? And nothing more?
And how can Pivotal users be really sure it went up on the other end?
Open Wide Technologies 14
All without burdening teams with tasks or tools they won’t use?

26. EasySOA & Nuxeo
Building EasySOA registry was an interesting journey
new challenging use cases for Nuxeo Platform
► new services and features
study “state of the art” SOA architectures
► improve how Nuxeo Platform exposes services

27. EasySOA Registry – EasySOA in Nuxeo Repository
Store SOA model inside Nuxeo Content Repository

28. EasySOA Registry – Nuxeo Repository
Store SOA model inside Nuxeo Content Repository
Manage configurations of the content tree
► tree snapshoting nuxeo-tree-snapshot
Multi-dimensional content tree
► proxies and publishing faceted search
► custom classifications nuxeo-platform-classification
Work on complex content
► quick preview
nuxeo-diff
► diff between versions of SOA definitions
Open Wide Technologies 28

29. Make SOA easy with Nuxeo
Improve Automation
Java Bean binding (5.7)
simplify data structures for easy mapping

Open Wide Technologies 29

30. Make SOA easy with Nuxeo
Connect Nuxeo to ESB
expose automation operations to the service bus
► expose high level / business custom services
bridge Nuxeo event bus with the global service bus

32. BONUS
Open Wide Technologies 32

33. Even more Light tools
EasySOA Proxy (“HTTP Mining”) :
listen to service exchanges to
► discover and register them
► record and replay them
► play alternative exchanges suggested
through correlation
► generate simulations or assertions
► trigger other services
SOAPUI integration (service testing) :
► generate SOAPUI configurations filled
with all EasySOA known WSDLs and
endpoints (“no more URL copy / paste”)
Open Wide Technologies 33

34. Even more - UIs
Indicators on the SOA model
► Amount of services without documentation,
► Without any implementation
► Or consumption
► Or endpoint
► Amount of unkown (« placeholder ») implementations
Service Browsing UI
► Service doc UI
► Tag them and browse by tags
