Atos and the Cloud
"The business has made some bad bets in the past – notably banking too much on cloud growth and breaking further into the US market."
Actually they did the opposite when cloud was accelerating - they doubled down on a complex JV with a full stack EMC on promise model called "Canopy" which promised AWS like pricing but on premise.
It did not go well and eventually it was dismantled, by which point the market had moved on. The also lacked the scale in applications compared to the India Heritage companies, Accenture, etc to access the higher value applications transformation/replatforming work (vs lift and shift)
