In this sample LS Central is located in the cloud with no direct database access, so Data Director has to use LS Central Web Service to retrieve the data.
POS Location using SQL Database mode
A dedicated host in the store runs DD Service and DD Web Service. The POS is offline and has its own DD Service.
Head Office Location in SaaS
LS Central sends the job data via DD Web Service (WS Distribution Server), which translates the job to standard DD Job Data package and forwards it to Data Director Service (Data Director). Data Director connects to LS Central SaaS Web Service to pull or send data (Replication).
The Replication FastTab must have a user name and password or a web key to connect to the Central Web Service, and the URL to RetailWebServices.
For oAuth (S2S) authentication to SaaS, the Replication FastTab must have the URL to RetailWebService, client ID, and secret and tenant ID.
The Scheduler uses LS Central Web service functions (Web Server) to query Replication counters and Actions for Action jobs.
POS Location using SQL Database mode
POS is just using standard Database connection. To be able to test connection, DD Web Service has to be set (WS Distribution Server). It is not needed for Job processing if the location is only destination location.
