4. MSO Interfaces – Other OpenECOMP Components
SDC
Distribution of orchestration artifacts (service & resource recipes and templates)
UEB event notifications, HTTP artifact retrieval
AAI
Query and update inventory
RESTful API
Cloud (Platform Orchestrator)
Instantiation of virtual resources in the cloud
Openstack APIs (primarily Heat and Keystone)
SDN Controller
Assign and configure network resources
Yang-based RPC and REST
App Controller (pending)
Assign and configure application resources
Yang and/or event based API

5. OpenECOMP MSO High-level design
MSO Sub-components(1)
API Handler
RESTful interface to northbound clients
Handle service-level and infrastructure (VNF & network) requests
Use MSO Catalog to map input requests to recipes (BPEL flows)
Track open and completed requests via MSO Request DB
BPEL Execution Engine
Execute BPEL service recipes
Sequence orchestration steps by invoking Adapters for each Resource in the recipe
request and configure network resources via SDN-C
manage cloud resources via PO (OpenStack)
configure Application VNFs via APP-C
update inventory via AAI
Perform additional orchestration steps (consult policy, etc.) per individual recipes
Perform error handling/rollback

6. OpenECOMP MSO High-level design
MSO Sub-components(2)
Resource Adapters
Provide interfaces to lower level controllers and other OpenECOMP components
Platform Orchestrator, SDN-Controller, APP Controller
Hides the details of complex interfaces (e.g. OpenStack APIs) via higher-level calls
Expose interfaces to BPEL flows as SOAP or REST APIs (synchronous/asynchronous)
Use MSO Catalog to map resource requests to a recipe/template
VNF > Heat templates
SDN Resource > Yang models
Merge input parameters with templates at run-time
Data Stores
Request DB
Tracks open and completed requests
MSO Catalog
MSO view of the SDC Catalog
Service and resource recipes, templates, and definitions
Populated via SDC distribution service
