Today every company of any size needs more or less complex information systems in order to be able to manage all its daily activities and to develop strategies for the future. The centrality of information systems in companies has grown in recent decades in parallel with technological innovation: the same technology, in fact, has "climbed" the different levels of the Robert Anthony’s pyramid. The aim of this thesis is to analyze how it is possible to integrate a legacy information system that has undergone multiple stratifications and customizations over the years with a service-oriented architecture that is compatible with all features characterizing the most recent information systems. In the first part of the work, after a brief presentation of Intesa Sanpaolo information system, we will illustrate the different orchestration paradigms and related architectures. Starting from orchestrations that currently can be defined as legacy, such as those that occur on the Mainframe platform, we will illustrate the more recent service-oriented architecture and its implementations. In the second part of the work we will analyze a particular banking service, the withdrawal service, to show the implementation differences between an orchestration on the Mainframe compared to that realized on a service-oriented architecture. The last part of the thesis is devoted to the comparison between the different implementations of the withdrawal service on the two architectures. Functional and non-functional requirements, KPIs and use cases will be analyzed to evaluate the effects that the transformation has had on the service. Finally, we will illustrate how it is possible to continue to integrate innovative technologies with legacy systems that allow the creation of core services of the bank. Particular attention will be placed on microservices.
