Infrastructure and file storage are also considered serverless, because the business (or person) that owns the system does not have to purchase, rent, or provision servers or virtual machines to use them.

As developers, if we take the old-fashioned approach (provisioning all of the infrastructure by using an on-premise environment), we have to set up all of the software and hardware requirements for every environment in which we want to deploy our software systems. This provisioning process has to be repeated for all of the environments, until we get into production, at which point we have to take care of other features, such as scaling and monitoring. In many cases, our infrastructure will be under-utilized, which is a waste of money, since we have purchased powerful servers to deploy applications that don't need many resources.
