web- and mobile-oriented architectures with oracle fusion middleware (oow 2014)
DESCRIPTION
Mobile applications as well as a large class of modern HTML5 web applications are built on top of an architecture with special provisions, such as RESTful services; the personal cloud, to provide a cross-device experience; push; cache; localization; scalability; and secure interaction with the enterprise back end. Gartner refers to this as the web-oriented architecture. Oracle Fusion Middleware offers key products (Oracle SOA Suite, Oracle Identity Management, and Oracle API Gateway) to implement this architecture, possibly in combination with cloud services such as Oracle Mobile Cloud Service, Oracle Messaging Cloud Service, and Oracle Storage Cloud Service. This session discusses the architecture itself and what it entails.TRANSCRIPT

Further Business Requirements
• Task Tailored UX• Up-to-date – near real time• Flexible – quick time to market for changes and updates
– Development and rollout
• 24/7 availability• Offline mode (synch upon reconnect)• Deferred, distributed conversations across devices
– Shopping basket
• Smooth experience, fast and appropriate response– Scalable
• Secure– Data on device, access by unauthorized parties, compliance regarding location

Summary
• Mobile and Web Oriented Architecture to achieve modern [mobile] UI• Special challenges on SOA infrastructure – scalable, available, reachable• With Oracle SOA Suite and Service Bus 12c we can
– Expose and invoke RESTful services– Deal with JSON data– Realize fine grained interaction with the Coherence cache
• Mobile Access Server enforces access from mobile apps• API Gateway can help to expose enterprise services to external
consumers in the DMZ – secure, virtualized, enriched, monitored• Oracle Mobile Cloud Service provides a cloud based environment
for implementing a substantial portion of the MOA/WOA– Taking the load of the enterprise environment
• And the external devices and users as well
– Providing MOA services such as push, cache, secure, monitor– Helping with ‘data shaping’ (JSON) and service exposing (REST)
• Note: REST, JSON, JavaScript are core technologies – server side too
