The OpenECOMP Portal is a platform that provides the ability to integrate different OpenECOMP applications into a centralized Portal Core. The intention is to allow decentralized applications to run within their own infrastructure while providing common management services and connectivity. The Portal core provides capabilities including application onboarding & management, centralized access management, and hosted application widgets. Using the provided SDK, application developers can leverage the built-in capabilities (Services / API / UI controls) along with bundled tools and technologies. Anchor Architecture Architecture
...
Any user seeking access to an OpenECOMP application will first visit the Portal, where authentication will be performed. Based on the user’s configured access level, the Portal will let the user access different application widgets, and might also redirect the user to a specific run-time environment.
From the Portal, users access applications and Key Performance Indicators. Administrators onboard and manage applications and hosted application widgets, and manage user access.
Here are two views of the Portal landing screen, one for administrators, and one for users:

Please refer to detailed architecture documentation here (ReadTheDocs link).
Designing Services
The Portal provides the following design-time features:
- Service Design and Creation (SDC): visual design tools for Services
- Policy creation (editing and conflict identification tools)
- Visual design tools for Analytic Applications (out-of-scope for first OpenECOMP releaseONAP release)
Instantiating Services
The Portal offers a Virtual Instantiation Deployment (VID) GUI to trigger MSO SO instantiation of Services and components that have been certified and distributed for production. These services may include:
- Infrastructure Services (such as compute and storage resources)
- Network Services (Virtual Network Functions)
- Application Services (such as a load-balancing function)
VID reads the models created in SDC, and, in turn, forwards the appropriate information to MSO SO during the Service instantiation process.
See the Installing and Running the ONAP Demos page for a scenario that uses the VID interface.
Administration
From the ECOMP PortalONAP Portal, administrators:
- access the same functionality accessible to users
- manage users and application admins
- onboard applications and widgets (developed using the Portal as a platform)
- edit the functional menu
User Guide
The forthcoming User Guide will provide a comprehensive user-focused view of the capabilities of the Portal.

For developers who wish to add applications that interact with OpenECOMP componentsONAP components, and offer a user interface exposed through the Portal, there is a Portal Software Development Kit (SDK). This SDK includes bundled tools, technologies, and built-in capabilities such as services, APIs, and User Interface controls. By adhering to the SDK, developers create applications that have a consistent look and feel, and can interact with other applications. Applications can be developed as full web pages or as functional widgets to facilitate a seamless user experience
Applications and widgets developed using the Portal SDK are onboarded via the tools available to an OpenECOMP Portal Administrator. The Administrator creates or assigns roles for the application, and makes the application visible to users via menus or links.
Portal Platform Main Components
Portal Core Integration: APIs in the SDK provide simplified integration between the OpenECOMP Portal ONAP Portal Core and OpenECOMP ONAP applications. By default, any application built on the SDK will have implicit integration with the Portal Core.
Centralized Access Control: The Portal core acts as a gatekeeper for all OpenECOMP ONAP applications. Site administrators decide who gets access to which applications with a distributed access management scheme.
...
Context-Aware UI Controls: Since the OpenECOMP ONAP Portal Core serves both as the point of entry and as the provider of context-aware menus and UI controls, it can ensure that when a user jumps from one application to another, the application menu items remain consistent and comply with the user’s access level. (This property of access control is called "Single Sign-On (SSO)".)
Visualization & Reporting Engine: This component is used to develop analytical reports and visualizations on AVP / RCloud / RSpeed / RAPTOR.
...
Web Component & Widget Development Framework: This framework is used to build widgets and visual components that will be hosted on the OpenECOMP ONAP Portal Core. It has access to services exposed by OpenECOMP ONAP applications running in separate environments.
