- High availability
Azure SQL databases are hosted on Microsoft owned, operated and secured data center.
You can start at $5.00 a month for 150 GB database and when needed the Azure SQL databases can be scaled geographically and horizontally.
- Elastic pools
Azure SQL databases can be charged for collective pool performance vs one Azure SQL database.
There should be no reason to start migrating some of your smaller and less critical apps to an Azure SQL database. Once you see its power and flexibility, larger and more critical database will follow the migration to SQL Azure.
