SQL Azure database is only a method of connecting to cloud services and storing your database in the cloud. Microsoft Azure is the best option for PaaS since it allows you to have many databases on the same account.
In the core, Microsoft SQL Azure is comparable to SQL Server in terms of accessibility, adaptability, and security.
A feature of the Microsoft Azure SQL database is that it automatically backs up each active database. To enable the 1-hour recovery point objective (RPO) for Geo-Restore, a backup is taken and geo-repeated on a regular basis.
