Book Description

Acomprehensive guide to learning container and application hosting capabilitiesin Cisco platforms, and implementing them to achieve higher efficiency innetwork deployments and operations

Cisco architectures offer comprehensive compute virtualizationcapabilities to accommodate both native and third-party container hosting, soyou can containerize and instantiate any application or network service andgain unprecedented value from your networks.

Direct from Cisco, this is the complete guide to deploying andoperating containerized application andnetwork services on Cisco platforms. First, the authors review essentialvirtualization and containerization concepts for all network professionals andintroduce leading orchestration tools. Next, they take a deep dive intocontainer networking, introducing Cisco architectural support for containerinfrastructures. Youll find modular coverage of configuration, activation,orchestration, operations, and application hosting for each key Cisco softwareplatform: 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 buildingand testing applications. They conclude with multiple use cases that show howcontainerization can improve agility and efficiency in a wide range of networkenvironments.

 

  • Reviewthe motivation, drivers, and concepts of computing virtualization
