AWS has always been the clear leader in public cloud infrastructure, and for many years, the cloud essentially meant AWS. There was no other serious contender. Everyone who was talking public cloud was talking AWS. The conversation changed in 2017. Subjects such as non-AWS public cloud solutions and how to build multi-cloud deployments started to become discussed seriously. AWS is still the clear leader, but it is no longer the only significant game around. In particular, Microsoft Azure has started to be recognized as a viable competitor for AWS. Most people still use AWS, but the money for cloud infrastructure is getting split more and with Azure in particular. This appears to be especially true in Europe.
