The SAS Cloud Data Exchange enables SAS users to connect and access data from a co-located database or from an on-premises database. The Cloud Data Exchange enables users to securely exchange on-premises data from behind a firewall to the SAS Viya platform in the cloud. All data transfer/exchange occurs on secured standard-based communications along with sophisticated authentication and authorization. The on-premises data center requires a single port opened through the firewall to facilitate the data exchange.
