Although Azure is the obvious Cloud service to host SQL Server, Amazon Relational Database Service (RDS) for SQL Server is a good choice when your organisation uses AWS. RDS deals with maintenance and monitoring, and supports the use of PowerShell to automate routine tasks. What if a script needs to be triggered by an unscheduled event?
