SQL AZURE is basically SQL Server Hosted in a cloud envirorment. This means it has the power of SQL Server and The power of Cloud Computing both held together.

SQL AZURE helps users Focus on their application and not the infrastructure required for running the application.

All the necessary Hardware, Software required for creation of SQL Server is taken care by the Cloud Service Provider.

By opting to SQL Azure the Hardware requirements and burden of hardware maintainence are moved away from the user and the user can concentrate on development of SQL Databases and hence enhances the ability of companies in creating SQL Code.
SQL Azure takes care of enviromental conditions like server setup, harddisk setup, processors etc and provides high availability, good levels of security.

SQL Azure Will for sure be the future of SQL Server databases as we see companies migrating from their self hosted servers to SQL Azure.

Users have high levels of options to opt SQL Azure in the Country Region where they wish to set up.

Users have to pay as they use and they would have options to reduce or increase their Disk spaces hence enhancing the Budget Capabilities of SQL Azure Users.
