There are many blog posts showing how to automate processing of a SQL Server Analysis Services model using either the SQL server agent or SSIS.
There are also many posts out there showing different ways of processing an Azure Analysis Services database through the use of Azure Functions, automation accounts, and runbooks. (SQLDusty.com, technet, Azure blog, official AAS docs, byobi.com)
Both of the above require some level of server administration privileges or Azure resource deployment.
What if you don’t have server admin rights or can’t create Azure resources?
