AWS Multi-AZ vs CLOUDBASIC Multi-AR

AWS RDS Multi-AZ vs. CLOUDBASIC RDS Multi-AZ-AR (MS SQL Server)

With CLOUDBASIC RDS AlwaysOn/Geo-Replicate for SQL Server Web Edition, Standard and Enterprise, you can deploy a much more cost effective high-availability solution, which offers a lot more benefits than the classic RDS Multi-AZ for MS SQL Server Standard and Enterprise (Web Edition is not supported; no access to the replica). With CloudBasic, you can deploy a true Multi-Region (or even multi-cloud*) server replication scenario, even with MS SQL Server Web Edition, with full access to the Read-Replica, while still paying 1/2 less than the AWS Multi-AZ deployment (which comes without access to the replica end point; doesn’t not support cross-region replication).

Here are sample scenarios to compare cost and benefits:
