This is mainly due to cost efficiencies gained from reducing per-unit costs when more of the same item is produced or more of the same workloads are processed.

This id due to the following reasons:

The standardized workloads can be executed on a highly integrated, massively replicable infrastructure stack. They don’t have to support a wide array of workloads and a heterogeneous stack of hardware, middleware, OS, and so on.
The computer hardware and network are highly streamlined and can be bought in bulk and configured to allow expansion. Often these companies require that hardware be engineered for their unique scaling requirements.
All software can be stripped down so that only what is necessary is loaded.
The service/software itself is written from scratch in a cloud-optimized way, tailored for efficiency at an instruction level.
The provider may not offer or guarantee a specific service level.
There is no need for virtualization technology to build virtual machines. The software can be engineered to the bare metal.
The profile of the workload is measurable and predictable simply by the number of users
