S-Drive has been built on Salesforce.com as a managed application and is delivered exclusively via the AppExchange marketplace. It is a native AppExchange application, meaning that it is built to run in the cloud with multi-tenancy and scalability in mind. S-Drive uses Amazon Simple Storage
Service as its file storage platform, whereas the Salesforce.com is used as the application platform as well as the file information database. Besides Salesforce.com and Amazon Web Services, SDrive does not use any other servers or infrastructure that may introduce security vulnerabilities.
