The ONAP Portal is a platform that provides the ability to integrate different ONAP 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.
Scope:
High-level Scope Overview:
The Portal provides a web-based user interface that provides access to all of the subsystems of an instance of ONAP.
It offers both design-time tools and run-time monitoring and control (for example: access to SDC, Policy, VID applications).
Any user seeking access to an
OpenECOMP application ONAP 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.
Detailed scope and purpose of Portal
ONAP applications can be divided into three main categories. Applications that are required at the design time, such as SDC, Policy creation, etc. Applications that support runtime time functions like A&AI, MSO, DCAE, SDN-C, and App-C. Finally, the applications that support administrative functions on the ONAP platform. As the number of applications grows, there is a need to have control over:
- What technologies are being used to develop?
- How can we ensure a consistent user experience is from one application to another?
- Who controls the access to the applications?
- How are applications managed and monitored. And how are new applications on-boarded?
- How the applications interact with other ONAP applications?
- How can the applications expose features and APIs to be consumed by other systems?
To address this, a platform and an SDK are being built to aid teams, who are tasked with building these ONAP applications. The platform includes two major modules: the SDK and the Application Portal Core. The SDK will provide a base framework for development teams, and will help in developing and releasing applications into production in a rapid and consistent manner. The applications built on this SDK will be controlled by a centralized ONAP Portal Core. Here are the details of both.
SDK
The SDK module will be used as a base for any ONAP application being built. It bundles together a host of different tools, technologies, and standards that will assist the teams during the development phase. It includes reusable UI components, authentication & authorization components, visualization & reporting engine, collaborative services, workflow manager, GIS / Map, web component, and widget development framework.
Any application based on the SDK will have implicit connectivity with a centralized ONAP Portal Core via a message-oriented middleware. It will be used for sending and receiving any data from the ECOMP Portal.
ONAP PORTAL CORE / RUNTIME
This will be a centralized web-based application running in the cloud environment and will be responsible for orchestrating all the other ONAP web applications. The ONAP Portal Core will include centralized access control, user management for internal/external users, dashboards, application administration, common UI controls, system monitoring/alarms/audit, system notifications, user messaging widget, context-aware UI controls, access history, personalization, service registration/discovery etc.
Any user seeking access to an ONAP application will first land on the ECOMP Portal Core where authentication will be performed. Based on the user’s access level, the ONAP Portal Core will let the user access different application widgets, and may also redirect them to their own run-time environments.
Designing Services
The Portal provides the following design-time features:
