Architecture Overview

The OSM code is organized into four modules. The following diagram illustrates how these four components fit together:

Launchpad (UI): Launchpad provides the user interface to the OSM orchestrator. From the Launchpad user can manage the catalog, compose the NS/VNF descriptors and perform the lifecycle management on Network Services. In addition, the UI also provides the ability execute the NS/VNF level configuration primitives. The following page describes Developer HowTo for UI Module
Service Orchestrator (SO): Service Orchestrator is responsible for End-to-End service orchestration. It is responsible for instantiating the NS, and starting the configuration plugins such as JUJU charms. The following page describes Developer HowTo for SO Module.
Resource Orchestrator (RO): Resource Orchestrator is responsible for creating and placement of compute and networking resources. It is also responsible for interfacing with SDN controller. The following page describes Developer HowTo for RO Module
Juju (CM): Juju provides the Configuration Manager for the VNFs. The Service Orchestrator interfaces with Juju server to configure the VNFs. For more information on Juju, the project is hosted on github: Juju development site. A guide for VNFs developers on how to develop Juju charms (language independent) can be found here.
