What are the required building blocks to place part of an application into the cloud?

Hi there,

I have a Windows client/server business management/accounting application written in VBA/Access.

I am thinking of making small parts of the application available in the cloud, for example QUOTES.

First of all, I am not sure if this forum is the right place to ask these questions!

I would like users to be able to access their quotes via tabled or smart phone and be able to add or modify records.

I am interested to find out what building blocks are required to achieve this.

My initial thoughts are as follows:

1. The user exports their quotes from the application (A) in XML format
2. The user uploads the XML data into SQL server on my website (?)
3. The user logs into a mobile app (B) that is connected to the SQL server
4. The user adds/modifies records in app (B)
5. The user then downloads their records in XML format from SQL server from my website (?)
6. The XML data is read and updated in application (A)

In terms of the SQL server I was also wondering if each user should have their own database or whether all users should use the same table QUOTES for example?

Any hints or tips would be really appreciated and many thanks in advance...

Have a wonderful day...

Kind regards,

Michael
