Agenda

• Context• Enterprise architectures• SOA – EDA – ESB - … SOS!• ECM integration• Sample case• Questions

The context• New IT projects rarely start in an empty context:

– Business applications– CRM– File servers– Databases– Workflow engines– Web servers– Portal– …

• Organizations tend to change frequently– Organisational changes– Mergers & Acquisitions– Outsourcing– …

• IT evolves quickly– New products– New standards– New technologies

The proposed approach

• We need an architecture which:– Is capable of supporting all the required services– Is flexible (from the IT and the organization

perspective)– Is scalable– Is evolutive and will last!

• Everything can change but the architecture itself must stay!

« Enterprise » Architectures• Not all architectures are equal…

N*(N-1)/2 N

SOA/EDA: definitions• Service-oriented architecture (SOA)

– Set of design principles for design and integration– Packages functionality as a suite of interoperable services– Services can be used within multiple separate systems from several

business domains→ Loosely coupled→ Synchronous architecture (request/response style)

• Event-driven architecture (EDA)– Software architecture pattern– Production, detection, consumption of, and reaction to events.→ Decoupled→ Asynchronous (publish/subscribe style)

• SOA and EDA are different but complement each other...

The ESB: combining the best of both worlds

• The Enterprise Service Bus typically provides:– A distributed services architecture, which includes a

lightweight container model for hosting integration components as remote services

– An enterprise messaging backbone for reliable delivery of messages between applications and services

– XML data transformation– Service orchestration and intelligent routing of messages

based on their content– A flexible security framework– A management infrastructure that lets you configure, deploy,

monitor, and manage your remote servicesEnterprise Service Bus: Theory in Practice (O'Reilly)

SOA and EDA complementarity

SOA:

• Vertical• Request/reply• Transactional

EDA:• Horizontal• Workflow type• Large processes

ESB

Integrating ECM

• Integrating ECM into the enterprise means:– Acquisition: acquire content from many

sources and many modes (push, pull, scheduled)

– Processing: transform, aggregate, index, repurpose, replicate content

– Delivery: syndicate or publish in multiple formats over multiple channels

– Integration: integrate with other information sources to enrich content

ECM integration possibilities

• All major ECM products offer some SOA/EDA integration support:– CMIS (REST)– SOAP Webservices– JCR (JSR 170) connectors– APIs… and coding– Webdav, FTP, watch folders,…

• Check what your ECM supports

ECM, SOA and EDA: an example• Poll an external ftp or

mailbox for scanned images• Perform OCR and extract

data• Transform this content into

PDF/A• Store PDF in the content

repository for retention• Send data to a business

application• Legacy application archives

the produced documents in the content repository
