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 9/23/17 © 2017 Edgecore Networks.

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 9/23/17 © 2017 Edgecore Networks.
