Document management - External cloud storage

Hello,

We have some issue with our customer regarding Document management deployment.

• Internal database has restricted storage capacity, which is not viable in the long run.
• FSS solution has a cost per utilization, which is not a possible solution regarding its cost

First, the customer project is the following :

• 1st go-live with an On-premise installation of IFS Cloud
• Switch from On-premise to IFS Cloud as a service installation
• Roll-out 6 months later on a IFS as a service installation

In the long run, document storage solution must be compatible with a Cloud installation.
 

Standard solutions offered by IFS in terms of Document storage does seems not to allow to have client-managed databases in a Cloud installation : e.g. an Azure Storage database owned and managed by the customer, which would be connected to the FSS storage solution.

My questions are the following :

• Can an Azure Storage database owned and managed by the customer be used in a FSS storage solution ? If yes, how is the setup made ? 
• If the first solution is possible, can we transfer the documents stored in the On premise database/File sharing repositories to the customer-managed FSS repository ?

Thank you

Pierre
