-===== Hosted Software Platform ===== 
-LTU engine/ON demand is a hosted software platform that provides access to LTU technologies’ comprehensive image recognition functionalities. The LTU engine/ON demand platform is highly flexible and is designed to adjust and scale with changing demands. ​ 
-A single account for LTU engine/ON demand can be used to add image recognition functionality to multiple applications. D 
-===== Service Modes ===== 
-The LTU engine/ON demand Modify API works in two modes: Asynchronous and Synchronous. ​ 
-Asynchronous mode is designed for important batch tasks, whereas synchronous mode is best to use during your initial testing with smaller amounts of images and when you need real-time updates for your application. ​ 
-The LTU engine/ON demand Query API is synchronous. ​ 
-All applications are by default initially set up in sync mode so you can start your tests and integrations with a smaller set of images immediately. We highly recommend switching to asynchronous mode when you are ready for your first batch upload of large image sets. Contact LTU support to switch an application from asynchronous to synchronous mode and vice versa. ​ 
-==== Asynchronous mode ==== 
-In asynchronous mode modifications to your database (add and remove images) will not immediately take effect. Modifications typical occur within 10 hours by default (contact LTU support if your application requires a different refresh schedule. ​ 
-All database updates are made in this mode -meaning that each query you make will start an action, but the query will return before the action is finished – database updates are basically queued and then processed. ​ 
-==== Synchronous mode ==== 
-In synchronous mode, when you query the Modify API the system will instantly process the query, update the database and your application. ​ 
-===== Administration Console ===== 
-The LTU engine/ON demand Administrative Console is accessed via. 
-URL: https://​www.ltu-engine.com/ ​ 
-See the Administrative Interface section below. 
-**LTU engine/ON demand** has the same Administrative Interface as the licensed version of LTU software: ​ **LTU engine/​server**. ​   
-Some aspects unique to LTU engine/ON demand found in comments marked with this symbol: ​ :!:  
-===== Application Programmming Interfaces ===== 
-Two versions of API's are described in this document: 
-SOAP API: SOAP was the API available in the intitial versions LTU engine/ON demand. ​ Its documentation is included here for reference purposes for existing applications. 
-JSON API:  the JSON API is the recommended API for new applications. ​ The licensed version of LTU engine includes the JSON API, which facilitates the porting of applications from LTU engine/ON demand to LTU engine/​server. ​ Query examples in the JSON API documentation generally reference LTU engine/​server.  ​ 
-:!: LTU engine/ON demand users will know to adjust the query examples to the proper /ON demand references. ​
