24. NetDevOps = Networking + DevOps
    • Based on Agile Manifesto and DevOps culture
    • It is talking about Network Automation
    1. Prevent Fat Fingers
    Ø“The CLI is Dead, API is Cool!“ (e.g. Ansible, gRPC, NETCONF, RESTful …etc)
    Ø“By 2020, ONLY 30% of network operations teams will use the command line interface
    (CLI) as their primary interface, down from 85% at YE16.” from Gartner report
    2. Repetitive Tasks
    ØMake reproduce and dispose operations more reliable and predictable
    3. Deliver source code
    ØReuse of known-good automation scripts increases admin confidence as well as task
    completion accuracy

29. Summary
    • Emerging trends shaping the data center
    1. Hardware and Software disaggregation
    2. Driving network automation is the rapid expansion of network
    infrastructure
    3. Increase strategic workforce, especially software part
    • Network engineers require skills include
    − Linux knowledges
    − Ansible (or others CM tool)
    − Network programmability skill
    − Continued learning and Open Mind
