Cloud Delivery Methods

Platform as a Service - Application platform for building and operating applications and services with supporting capabilities (authentication, authorization, session management, transaction integrity, reliability)

10

Cloud Delivery MethodsSoftware as a Service -A pre-built application in the cloud with multi-tenancy, pay-as-you-go model and the ability to provision on demand
