Thanks, yes, that makes sense.

So that means if I gives the MSA account the appropriate permissions to the databases on the other sevver, or file directory on the other server, it should be able to log in as a service to do the task for example SSIS package.

So I see the msa account is the same as a domain account. I don't see the difference.

When we create a domain account for SQL server services, we also register the SPN.

Is there a reason MSA account as the first choice other than a domain account?

Thanks
