I would like to buy a mobile service but I didn't understand what Microsoft intend for API for Unit. Are Units the amount of people that have the app in their mobile device?
What Microsoft intends for API and for Unit?
here the calculator http://azure.microsoft.com/en-us/pricing/calculator/?scenario=mobile
In my case I have a company application that probably will be distributed through company hub to about 20 people.
We have also developed a desktop application that accesses to the Azure database directly like a normal network connection to a Sql Server. The database contains about thirty tables and mobile service allows access (insert, update, delete) to each table.
I don't understand if I need a base account a premium or if a free account is enough at the moment. How can I choose the best configuration for my mobile app? Can I try Azure for free, without any risk of being charged? If i use the try Azure for free and it isn't enough can I upgrade and pay for my needs?
