Societe Generale Group is accelerating its digital transformation and the transformation of its information systems.As part of a comprehensive strategy incorporating several approaches, including service-oriented IT and the use of APIs (application programming interfaces), Societe Generale is studying how to make the best use of Open Source development throughout the Group. This comes at a time when the use of open source frameworks is increasingly essential both in the infrastructure of our business lines and in the development process. Additionally, some of the Group's developers are also contributing to various public open source frameworks. Thus, Open Source is essential to delivering the Group's digital transformation and the bank of tomorrow.
OPEN BANKING ARCHITECTURE

Although the term SOA (service-oriented architecture) is not new, today this approach is no longer seen merely as an option for helping our business lines create value for our customers.

The use of Open Source development is a part of this strategy, and is applied at Societe Generale through the Open Banking Architecture approach, which is structured around three main pillars: the establishment of technological norms and standards (rest/json, oauth, etc.), the creation of an operational governance model and the development of a “developer-centric” service catalogue.

 

USING AND CONTRIBUTING

Going forward, for each new project, the added value generated through Open Source development will be evaluated. This approach was initiated by the company's developers who wanted to share practices, standards, technology building blocks and so on to help them innovate faster. After extensively studying the market, their conclusion was unequivocal: Open Source is one of the most powerful drivers of innovation.

In addition to development tools, the teams tested infrastructure middleware as well as databases. Thus, all of the components of our information system are involved. This approach has led to the addition of PostGreSQL as a relational database standard at Societe Generale. When it comes to more sophisticated projects, such as Big Data, the IoT, machine learning and Elasticsearch, Open Source has become essential. For example, improving customer knowledge is inconceivable today without Hadoop.

For the developers at Societe Generale, using Open Source goes hand in hand with contributing to it. Many developers, who are passionate about what they do, had already been contributing to many projects in their spare time. In the professional context, projects that will see contributions going forward include AngularJS and Hortonworks (Hive, Flum). More than 30 community projects have already been identified for potential contribution down the line by the developers at Societe Generale.

FOCUSING ON SECURITY AND CONTINUOUS DELIVERY

Security issues are a priority for the banking sector. Open Source solutions are no more and no less secure than traditional solutions, and therefore require the same vigilance as proprietary products.

Such an approach helps the Group better handle its strategic decisions in terms of software, simultaneously taking into account aspects of cost, security, standardisation and innovation.

In the digital era, Open Source development takes on strategic importance and enables us to streamline our development processes so that we can achieve continuous delivery. In concrete terms, we have created “Fast-IT” teams within a Group entity whose job is to create and launch applications in a span of less than one month for the fastest projects. To achieve such levels of agility, they use Open Source technology.

Spurred on by the developers, this approach has made its way into the Group through multiple awareness and training sessions and the availability of all of these technologies in “as a service” mode. It can be seen, for example, in our research efforts on Docker and containers. Without being overconfident, we can say that the initial results confirm the validity of this strategy.

Finally, Open Source also serves as a gateway to new practices in digital technology. Open Innovation at our “Les Dunes” technology hub offers an illustration of this, with its community-based working methods (hackathons, meet-ups), its collaboration with competitiveness clusters and start-ups, the creation of labs and increased experimentation.

Our next event will be an Open Source Forum, a full-day event taking place at “Les Dunes” on 29 November. We have invited major players in Open Source development including Google, GitHub and INRIA (French Institute for Research in Computer Science and Automation).
