Communication Service Providers’ networks are evolving to virtualized network with deployment of VNFs in the cloud through automation and orchestration. In this workshop, students explore the deployment of VNFs in a cloud through VNF instantiation, configuration and connectivity to the rest of the network. Students monitors various events of the VM such as logging, alarms, KPI monitoring, tracing, restore and upgrade. Once the students have the foundation of all troubleshooting related artifacts, they go through various break-fix scenarios to build the problem isolation skills through hands-on exercises.

This course is intended for a technical audience in engineering, deployment, operation, and performance monitoring that has knowledge of networking applications.

After completing this course, the participant will be able to:
• Describe connectivity in the cloud based global network
• Step through the intra and inter-data center connectivity and the role of underlay and overlay networks
• Step through the VNF instantiation process and configuring VNF for connectivity
• Examine the monitoring configuration for a VNF or Service
• Isolate communication issues related to VNF connectivity
• Capture and analyze VNF interactions using the virtual probe
• Analyze the Key Performance Indicators (KPI), Key Capacity Indicators (KCI) and Telemetry to monitor VNF performance
• Perform the VNF Backup and Restore processes
• Perform basic Validation Testing of networked entities
• Differentiate between configuration vs. networking issues
