Cloud Migration Strategies: a structural challenge for companies

19 avril 2023 | ACTUALITÉS, Cigref in english, Communiqués

Cigref publishes a report on the results of the work of its working group on « cloud migration strategies », co-chaired by Jean-Christophe Lalanne, EVP IT at Air France KLM, and Stéphane Rousseau, CIO at Eiffage. This updated version of the first version of the Cloud Migration Strategies report, published in 2021, takes a closer look at the cloud migration projects of companies and administrations.

Presented last year as the essential foundation for the information systems of companies and public administrations, the cloud continues to be deployed within organisations. In fact, in 2021, the cloud will be present in 21% of European companies, five times more than in 2018, according to Eurostat. The question is therefore no longer whether to migrate one’s information system to the cloud, but how to do so.

While we may no longer need to reiterate the benefits that this shift can offer companies, such as agility, flexibility and time to market, several topics still need to be addressed. In this respect, the prediction we made last year seems to be coming to pass: by 2025, most organisations will have made their migration to the cloud.

With this in mind, the study focused on the means used to migrate to the cloud – the « how », in other words.  The group then focused on software migration, a key issue in this year’s work. Finally, we considered the secondary benefits of the migration, such as mapping the software base, securing the IT system, dealing with technical debt, and responding to environmental challenges.

At the end of the second year of work on cloud migration strategies, the group shares a twofold observation: on the one hand, many of the questions raised have been answered through the discussions and comments of the members and, on the other hand, these discussions have revealed new problems that require some distance for solutions to emerge. For this reason, Cigref does not plan to maintain this working group in its business plan for 2022-2023. The cloud will remain present in several other Cigref activities, notably in the Supplier Relations working groups. The objective is to allow member companies and administrations to pursue their migration plans and gain experience on the subject before possibly setting up a new working group in the future.
