SQL Azure has evolved from its early code names to provide a relational database management system hosted in the cloud. It can be accessed from SQL clients, ADO.NET data services, and Windows Azure web/worker roles using the TDS protocol. The SQL Azure portal allows provisioning databases within an account. Databases have size limits and logins map to SQL users. Tools like the SQL Azure Migration Wizard and Management Studio help migrate on-premise databases and provide management capabilities. Minimal code changes are needed to access cloud databases, and the web app development process is similar when deploying to Windows Azure.
