The cloud isn't the right solution for everything, but I've been migrating infrastructure from on-prem to the cloud for ~10 years and it's saved money, simplified processes, and improved performance in every single case. I've also done a lot of work rearchitecting cloud infrastructure with the same effects.
It all comes down to architecture and design. Many applications aren't designed for the cloud, and of course those systems are costly and painful to run in the cloud.
