What are the different deployment options in SAP Fiori?

The SAP offers many ways to deploy Fiori applications. There are five deployment options the customers can choose from. The deployment options are - 

Gateway Embedded - the SAP gateway is embedded in the backend system

Front End System embedded deployment - a single SAP landscape where Fiori is embedded.

Front End System hub deployment - the components of the Fiori UI, SAP Launchpad, and SAP Gateway are bundles together. Business logic and conventional UIs remain on the backend, so several backend systems can be integrated with Fiori

SAP Fiori Cloud - the Front End System is in the cloud and allows to connect with back end systems in on-premise.

Gateway hub - the SAP Gateway acts as a hub to connect the backend system with the front end system in the cloud.
