We would like to enable SAS Viya multitenancy in Development environment . Development Environment used for testing SAS Viya application but not for resource intensive user/business process. Please advise if any system resource dependency or constraint in enabling muti tenancy .In other words I would like what is minimum CPU /Memory required to enable multi tenancy, for CAS , SPRE and worker nodes.
In terms of resource dependency, you will need to look at your identity provider(s): LDAP, AD, etc, as you would need to create the organizational unitls (OUs) accordingly.
Indeed, as @Anand_V proposed, if you had already multi-tenancy enabled you are good to go to create the new tenants. Otherwise, you might need to re-install SAS Viya, re-configure and migrate your content (reports, data, etc) you the initial tenant at least.
This being said, we cannot help you in terms of your sizing. You need to look at the current usage, estimate how much would each tenant use, and expand resources (disk, RAM, even cores if the licenses allow you) accordingly.
If you need support with this task, I always advise to get professional support from SAS or a trusted SAS partner that would be specialised in this particular area.
