NSP Workflow Design and Management

Course Number: OS00105-W-2000
Course Duration:  2 hours 
Price: $250 US

Course Overview

This eLearning explores how the NSP Workflow Manager allows the design and management of “workflows” to automate network operations.  Discover the structure of a workflow and related technologies such as Mistral, YAML and JSON.  Learn Mistral DSL advanced concepts, actions and expression functions and NSP actions and expression functions to design your workflows.  See how the Workflow Manager (WFM) provides a user-friendly interface to design, create, execute and manage workflows. Explore WFM enhanced functionality such as environments, Kafka triggers and Jinja2 templates.  Demo workflows are used to execute multiple use cases such as commissioning a Nokia 7750, CFlash drive cleanup, SSH user creation and creating a Kafka trigger.
