If you need to migrate to Azure at end of support (EOS), and you require high availability for SQL Server 2008/2008 R2, there’s only one solution recommended by Microsoft: SIOS DataKeeper. SIOS DataKeeper enables clustering in the cloud, including the creation of a SQL Server 2008/2008 R2 FCI, allowing you to achieve your HA goals.
This white paper will give you an overview of a complete, high-availability move to Azure, including an overview of how SANless clusters work and what it takes to deploy Windows Server failover clusters with SIOS DataKeeper.
