Cloud as catalyst for modern applications.

Blog: Capgemini CTO Blog

Society and companies face the digitalization of their processes and modes of interaction. Whether they are intended for customers, employees, or citizens, the expected services must meet the challenges of digitalization. The recent health crisis has confirmed the importance of efficient and secure digitization.

For large companies and public bodies, which have often invested tens or even hundreds of millions of euros in their information systems, pooling their know-how and often creating a structure enabling them to stand out from the competition, the response to the digitalization challenges cannot involve the construction of entirely new solutions. The most advantageous approach is to rely on modern technological solutions to renovate and open the existing systems and enrich them with new components: in this case, we speak of modernization of the information system. In some cases, the gap to be filled is such that it is more relevant to consider a profound transformation of the existing situation.

Cloud platforms are essential to speed up these modernization approaches:

To successfully modernize its information system by taking advantage of the cloud, it must be considered as a corporate program federating businesses and IT, and its justification formalized in a business case. This business case relates the investment and the expected value creation such as an increase in revenue by grasping the digital opportunities more efficiently, a reduction in time to market, or a decrease in operational costs, as well as increased control of operational risks such as reduction of the technical debt or improvement of cybersecurity. Apart from the mobilization and the techno-economic justification, experience has shown that the effective implementation of a modernization program towards the cloud must obey key principles:

As modernization typically spans several semesters and focuses on a hybrid cloud infrastructure, it is essential to obtain a hybrid integration platform that can manage various exchange flows between applications on and off the cloud, as well as between existing and modernized applications

What is the best way to organize and orchestrate this modernization?

The bases underlying modernization of the existing portfolio (reference architectures, cybersecurity rules, Infrastructure-as-Code module libraries, etc.) are becoming accelerators for new cloud-native projects. Such a base also facilitates the implementation of rapid application development solutions, on secure platforms connected to the company data – this is the low code. It is therefore possible to avoid shadow IT and to offer the new generation of citizen developers the means to put into practice their ideas for improving processes, sometimes constrained by the unavailability of development resources.

All these efforts are driven by data, the most important asset of organizations! By modernizing the IS, it will be possible to process it more efficiently and to enhance it in a way that is more secure for the organization and its end customers – employees or users. In addition, the cloud provides access to numerous value-added services to accelerate innovation and remain competitive: for example, cognitive or conversational services, machine-learning tools, on-demand computing power for simulation and optimization calculations, etc.

The Information System cannot be modernized without changing the skills and operational practices of the teams responsible for maintaining and supporting it. It is therefore essential to support employees in their acculturation to the cloud and the enrichment of their skills. Everyone must play a role in this human adventure of which the cloud is only a catalyst.
