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

3. 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

4. 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!

5. « Enterprise » Architectures Not all architectures are equal… N*(N-1)/2N

6. 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...

7. 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 services Enterprise Service Bus: Theory in Practice (O'Reilly)

8. SOA and EDA complementarity SOA: Vertical Request/reply Transactional EDA: Horizontal Workflow type Large processes ESB

9. 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

10. 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
