![]() The left side of the following diagram shows how the application stack has been split into distinct models. The model elements, such as tables, forms, and classes, are represented by an XML file that contains both metadata and source code. The model store is represented as a set of folders and XML artifacts that are organized by model. Therefore, even when active clients try to authenticate by using ACS, they must use passive client authentication, in which a browser dialog box prompts the user to enter their credentials.Ī completely revamped metadata subsystem incorporates the new compiler and Microsoft Visual Studio–based development model. A web browser is an example of a passive client.Ĭurrently, Access Control Service (ACS) doesn't support a mechanism for non-interactive authentication. A passive client relies on HTTP redirects for authentication. Passive clients can't programmatically initiate actions based on responses from the server.A smart/rich client is an example of an active client. An active client doesn't rely on HTTP redirects for authentication. Active clients can programmatically initiate actions based on responses from the server.Two types of clients must be considered for access in the cloud: active clients and passive clients. The security subsystem uses the same AuthZ semantics for users and roles. The recommended primary identity provider is OrgID, and the store for the identity is Azure Active Directory (Azure AD). A user can use a combination of clients and credentials to access it. It is hosted on Azure and is available for access through the Internet. In the cloud, it's deployed to Microsoft Azure infrastructure as a service (IaaS) virtual machines (VMs). The server, including the application code base, is deployed to an Internet Information Services (IIS) web application. The form objects still run on the server, and rendering has been optimized for browsers and other clients through server and client-side (browser) investments. There is no longer any remote procedure call (RPC)-based communication with the server. The services endpoint on the server is now responsible for returning all form and control metadata and data to the browser-based client. Note the following important points about the changes in the server architecture: The separation enables new application development on the base foundation models, just as the Fleet Management sample application has been developed. The application stack is divided into several models: Application Platform, Application Foundation, Test Essentials, and the application suites. The application stack and server architecture align with three key pillars: Some examples are Application Suite, Ledger, Retail, and Case Management. There are many application-specific models. The platform models are Application Platform, Application Foundation, and Test Essentials. The application stack is divided into platform models and application-specific models.
