The 3rd annual European sovereign cloud day took place in Brussels on 3 June 2025 gathering representatives from cloud vendors, service providers, industry experts, as well as members of the European Parliament. Keynote speeches and panel discussions casted some light on the new sovereignty challenges cloud providers and buyers in Europe are facing, which we can summarize around three major themes: 1) An unavoidable need to focus on AI sovereignty; 2) An urgent call for standardization; 3) A shift in perspective from data protection to resilience.
