Containers in Cisco IOS-XE, IOS-XR, and NX-OS: Orchestration and Operation / Edition 1

by Yogesh Ramdoss, Nagendra Kumar Nainar

Overview

A comprehensive guide to learning container and application hosting capabilities in Cisco platforms, and implementing them to achieve higher efficiency in network deployments and operations

Cisco architectures offer comprehensive compute virtualization capabilities to accommodate both native and third-party container hosting, so you can containerize and instantiate any application or network service and gain unprecedented value from your networks.Direct from Cisco, this is the complete guide to deploying and operating containerized application and network services on Cisco platforms. First, the authors review essential virtualization and containerization concepts for all network professionals and introduce leading orchestration tools. Next, they take a deep dive into container networking, introducing Cisco architectural support for container infrastructures. You’ll find modular coverage of configuration, activation,orchestration, operations, and application hosting for each key Cisco software platform: IOS-XE, IOS-XR, and NX-OS.The authors explore diverse orchestration tools, including LXC,Docker, and Kubernetes, and cover both Cisco and open-source tools for building and testing applications. They conclude with multiple use cases that show how containerization can improve agility and efficiency in a wide range of network environments.

• Review the motivation, drivers, and concepts of computing virtualization
• Learn how Cisco platforms are achieving infrastructure virtualization
• Explore the Cisco reference model for developing cloud-native services and moving to cloud-native network functions
• Master Cisco container networking fundamentals, supported modes, and configuration
• Enable,install, activate, and orchestrate containerized applications in Cisco IOS-XE,IOS-XR, and NX-OS
• Compare tools and methods for developing, testing, hosting, and orchestrating containerized applications
