Gartner analysts evaluate the DIH as an emerging paradigm for an easy, fast, and highly scalable access to services, which are necessary to successfully address customer experience improvement initiatives, systems modernization, and openings to new business partnerships. A paradigm that provides for access to applications and business system data through application programming interfaces (API) without the need for radical transformations, extending the operational life of legacy systems and avoiding their overload.
APIs securely power the front-ends with which business users and customers interact; likewise, they support integration with business partners and third-party applications, opening up new possibilities for growth and expansion within the API Economy paradigm.
Speaking about data, DIH allows overcoming the rigidity and limitations of existing backends, supporting real-time data-streaming and high-performance data stores, through the Fast Data paradigm. These capabilities maximize the value of data to the business by providing consolidated Single Customer Views of each customer and analytics data updated in real-time about customers, without relying on batch processes.
Where to start to put digital decoupling into practice
The implementation of a digital decoupling process begins with the creation of API Gateways to manage client calls and route them correctly. It continues with the creation of microservices in backend for frontend (BFF) logic to separate the significant developments and evolutions for the user experience from those concerning the infrastructure, migrating the application logic to the DIH platform.
Subsequently, by introducing a Fast Data architecture, composed of a real-time stream of data and single views according to the needs of the business, the real separation of the channels is achieved, which are thus freed from the underlying logic.
At this point, it becomes easier to evolve individual components and eventually replace the underlying systems to optimize costs, exploit cloud resources, and much more, without affecting the operation of applications.
The benefits of digital decoupling
Decoupling the systems from the channels, by inserting a digital decoupling layer, offers IT the availability of a performing infrastructure, which allows it to exploit the potential of corporate SORs, freeing themselves from possible critical issues. Development teams can thus create new software quickly and securely, taking advantage of the latest technologies.
This way, teams can focus more on interactive features, without having to worry about the underlying systems. From a business point of view, the separation is functional to time to market, to the improvement of the user experience, and to the more effective use of IT resources.
