Are there any SOP(s) or template(s) for determining sizing of the environment for SAS 9 applications for on -prem or cloud environments? I am aware that it depends on a number of factors but I would like to know the approach followed by the SAS technical team in this regard.
I am not sure if you were able to find answer to this question. But IMO, SAS doesn't publish sizing based for generic workloads, except for the minimum resource requirements for each solution. This could be because every environment sizing could vary based on the type of workloads it will be used for.
Also, SAS provides a free sizing report for every environment, so you can reach out to your account management team for this report. There should be a template questionnaire to be filled based on the workload requirements that is shared by SAS, based on which sizing could be determined.
