Can hosters run all SQL Server 2016 editions via SPLA on infrastructure provided by a third party IaaS provider (Data Center Provider)?

No, only those SPLA products /SKUs which are licensed “Per SAL” (user) are allowed to run when using a third party infrastructure (Data Center Provider). Therefore, SQL Server 2016 SKUs such as Web Edition and Enterprise edition may not be used as these SKUs are licensed only “Per Core”.

Please refer to the DCP Eligible section of the Service Provider Use Rights for more information.
