Symfony can be used as a middleware framework to build modular e-commerce applications. Key areas include a product information management system, customer relationship management, order management, search, catalog, checkout and payment processing. Third party services can integrate via REST APIs for areas like media storage, payment processing, recommendation engines and marketplaces. The document emphasizes separating applications by domain, using Symfony bundles appropriately, and planning for scalability.

Even though it’s interesting to meet all
business requirements within the same
application
 !!! Difficult to maintain
 !!! Complex and unuseful business rules
 Changes on the solution core
Making e-commerce with a blogging
solution… No !
 Separation of concern : CMS / E-commerce / BI
Your e-commerce is not a business
intelligence tool : keep simple kpi on your
dashboard but use a real tool like Pentaho
or JasperSoft for your BI

Do smaller things and reduct the coupling of apps
 Core API
 Fine management of ACL through an oauth server for instance…
 Design applications by domain:Doing less but doing better
o Facilitate the update of a service / its maintenance / its availability
 Let‘s forget monolithic applications
o The applicative segmentation by controlers is not enough
 Why not considering a segmentation by functional domain ?
