Agenda

Mainframe as a services providerServices oriented new applicative architecture

Services architecture using SOA layers patterns and principles.

Services are common for all the consumers (CICS / Batch / ESB / DB2 Stored Procedures).

Services’ operations have a high level of reusability.

Services are developed using the framework and based on the same model

Development framework : Abstract the common tasks for the developers.

Scriptura integration – Native services Business services and used methods

FMSB IT Transformation plan

More than 180 services’ operations have been developed

Legacy applications refactoring is in progress

Scriptura phase 1 integration is in progress

ESB services using the new natives services have been developed

JBOSS will call the ESB soon (2 projects will start soon)
