21. Azure Database (PaaS) v/s SQL on Azure VMs (IaaS)
Azure SQL Database (PaaS)
SQL Server in Azure VM (IaaS)
Best for
New cloud-designed applications that have time constraints in development and marketing.
Suited for Software-as-a-Service applications.
Existing Dev Cert & test environments applications that require fast migration to the cloud with minimal changes & you do not want to buy on-premises nonproduction SQL Server hardware.
SQL Server applications that require accessing on-premises resources (such as, Active Directory) from Azure via a secure tunnel.
Rapid development and test scenarios when Disaster recovery for on-premises SQL Server applications using backup on Azure Storage or AlwaysOn replicas in Azure VMs.
SQL Support
Near SQL Like Functionality in preview. Application should be supported on Azure SQL Database. Existing environments cannot be migrated to Azure Database unless application is rewritten.
All SQL versions (SQL 2005 – SQL 2014) are supported similar to on-premise functionality. Existing applications can be migrated with minimal coding effort
Size Constraints
Databases of up to 500 GB in size.
Database Any Size
Resources
SQL Azure Database can be provisioned by the DBA Team after which there is minimal intervention & Support from DBA Teams.
Winserv Team governs the VMs images while DBA Team governs the SQL setup, administration & support similar to current SQL environment
Total cost of ownership
Eliminates hardware costs. Reduces administrative costs.
Eliminates hardware costs.
Business continuity
In addition to built-in fault tolerance infrastructure capabilities, Azure SQL Database provides features, such as Point in Time Restore, Geo-Restore, and Geo-Replication to increase business continuity. For more information, see Azure SQL Database Business Continuity.
SQL Server in Azure VM lets you to set up a high availability and disaster recovery solution for your database’s specific needs. Therefore, you can have a system that is highly optimized for your application. You can test and run failovers by yourself when needed. For more information, see High Availability and Disaster Recovery for SQL Server in Azure Virtual Machines.
Hybrid cloud
Your on-premises application can access data in Azure SQL Database. But from SQL Database we can’t access resources on-premise
With SQL Server in Azure VMs, you can have applications that run partly in the cloud and partly on-premises. For example, you can extend the on-premises network and Active Domain Directory to the cloud via Azure Network Services. In addition, you can store on-premises data files in Azure Storage using the SQL Server Data Files in Azure feature. For more information, see Introduction to SQL Server 2014 Hybrid Cloud.
