I have a client having 50 stores and one Head Quarter and all are connected through static IP.
All the stores have different databases and Head Quarter contails all data of all stores.If a customer comes in a store and the store issues a voucher to the customer, that voucher should be cashed at any store.I want to develop a web service which will be called at store and will connect to Head quarter to check balance of the voucher.
All stores and Head quarter are connected through internet.
Can I host the web service at Head Quarter ?
Or I will have to host the web service at ISP ?
