Abstract: Examples disclosed herein relate to using a tenant data mapping for multiple tenant cloud applications. For example, a processor executing tenant access instructions may retrieve data related to a tenant associated with a user login and data related to tenants with a hierarchical relationship to the tenant and create a mapping including the retrieved data.

Abstract: A network system for implementing a cloud platform within a network to which at least one device defining a computing environment for a user has access comprises an application management module, a community management module, and a user enrollment portal. The application management module enables access to an abstract application, wherein the abstract application is associated with a concrete application defining an implementation of the abstract application for the computing environment. The community management module manages a community, wherein the community comprised of at least a user credential and the abstract application, wherein the community defines at least one of said following: a policy, a management process, and a service, under which the abstract application can be accessed by the user.
