SOA e IMS (NGN)
The document discusses how IMS (IP Multimedia Subsystem) and SOA (Service-Oriented Architecture) can help reduce the time needed to implement new services. IMS provides an open standard architecture for converged multi-media services across networks. SOA allows applications and services to be built in a modular way and connected through published interfaces, improving flexibility and integration. Combining IMS with SOA principles like loose coupling, reuse, and abstraction allows services to be deployed more quickly.

IMS is emerging as the “glue” that will allow operators to create, scale and evolve converged services, quickly and cost-effectively : Services that can straddle networks — old and new, wired and wireless, data and voice, yours and mine; Services that will blend multiple modes of communication seamlessly — text with voice, chat with mail, video with blog; Services that will be defined and delivered at a fraction the cost and the time required today. http://www.stlpartners.com/ims.php http://soasimples.com

Editor's Notes
- #17 Operational Data Consistency Gartner defines an ESB as a messaging infrastructure that connects and unifies interactions between services in an SOA. In other words, the ESB enables "plug and play" communications between SOA services. Yet an ESB by itself does nothing to ensure that data interdependencies between services are handled properly. A traditional application is usually deployed as a "silo," meaning the application has its own database that contains a copy of operational business data needed by that application such as customers, products, and inventory levels. Typically, each data silo gets synchronized only periodically, so between synchronizations each silo has slightly different data. These data inconsistencies can cause business errors when silo applications are integrated using an ESB. When silo applications are turned into services, each with different inventory data, you encounter problems (see Figure 2). In this example, the "show status" service thinks that the inventory level is 27, while the "check_avail" service thinks that the inventory level is 0.
