I am working on standing up a mobile app with Google Datastore as backend database. I am debating whether google datastore is right choice for below use cases vs other datastorage options google offers. We are a small team and we don't want to incur lot of operations costs in the initial run. Application will have the following use cases:
User registration and profile which will take user personal identification details like credit cards, bank account , emails,address etc
Various subscription plans like yearly subscription price, monthly subscription price and pay per single service . User will be charged with bank account or credit card set on user profile
Mobile app will be launched within next 2 months and i am expecting at-least 1000 users in first few months
Appreciate your feedback at this stage where we are laying down the foundation of the app
Thank you
