Enterprise Architecture

Enterprise Edition Features & Tradeoffs Completely isolated from other tenants Fs-.cloudapp.net Exclusive use of dedicated hosted service(s) SQL Azure databases Little or no change to the existing application codebase The provisioning automates the customization of the app creates a package dynamically …but requires a manual step Maximum clarity in the billing Federated SSO No need for account provisioning, reuse existing org structure The # of actual users is unknown
