Major cloud providers would disagree! Serverless aims not to remove using servers, but instead to remove the responsibility of managing servers from the user. In the case of a physically failing server, the serverless provider is responsible for ensuring fault tolerance. Big cloud providers are in a better position to provide that tolerance than if you run your own services.

Serverless architectures have tremendous use in event-driven environments. Consider a business need to transform images by adding a watermark and adding metadata to images uploaded to their service.
