Cloud service providers customize iApps® application templates based on your needs as a cloud tenant. For example, they specify such things as an IP address for a virtual server, identify hosts and server pools, set connection limits, and so forth. This customization eliminates the need for you to perform complicated networking tasks, and ensures that your settings are optimized for your resources. When these customized applications are associated with you as a tenant, you have the option to further modify the application parameters that your administrator has defined as tenant editable, and deploy them as needed.
When a cloud administrator adds you as a cloud tenant user he determines which resources are available to you. These resources are provided by associating customized application templates with your account. Part of that customization task is to define the application parameters you can edit. As a cloud tenant user, you can customize these application templates and deploy them as needed.
