Modernize and optimize network management with APIs and automation

Legacy network management approaches dont scale adequately and cant be automated well. This guide will help meet tomorrows challenges by adopting network programmability based on Application Programming Interfaces (APIs). Using these techniques, you can improve efficiency, reliability, and flexibility; simplify implementation of high-value technologies; automate routine administrative and security tasks; and deploy services far more rapidly.

Four expert authors help you transition from a legacy mindset to one based on solving problems with software. They explore todays emerging network programmability and automation ecosystem; introduce each leading programmable interface; and review the protocols, tools, techniques, and technologies that underlie network programmability. Youll master key concepts through hands-on examples you can run using Linux, Python, Cisco DevNet sandboxes, and other easily accessible tools.

This guide is for all network architects, engineers, operations, and software professionals who want to integrate programmability into their networks. It offers valuable background for Cisco DevNet certificationand skills you can use with any platform, whether you have software development experience or not.

Master core concepts and explore the network programmability stack
Manage network software and run automation scripts in Linux environments
Solve real problems with Python and its Napalm and Nornir automation frameworks
Make the most of the HTTP protocol, REST architectural framework, and SSH
Encode your data with XML, JSON, or YAML
Understand and build data models using YANG that offer a foundation for model-based network programming
Leverage modern network management protocols, from gRPC and gNMI to NETCONF and RESTCONF
Meet stringent service provider KPIs in large-scale, fast-changing networks
Program Cisco devices running IOS XE, IOS XR, and NX-OS as well as Meraki, DNA Center, and Webex platforms
Program non-Cisco platforms such as Cumulus Linux and Arista EOS
Go from zero to hero with Ansible network automation
Plan your next steps with more advanced tools and technologies
