Please explain SQL Azure “master” database

Question

What\'s the \"master\" database in SQL Azure for? I just created a subscription and once I created a \"new SQL Server\" I immediately got \"master\" database with 1GB size.

Answer 1

master is a required system database that's responsible for holding info about all the the other database on the server instance, system metrics/config, managing logins & database creation etc, its read-only and can't be removed.

You will need to create a new database and deploy to that.
