A comprehensiveguide to learning container and application hosting capabilities in Ciscoplatforms, and implementing them to achieve higher efficiency in networkdeployments and operations
Ciscoarchitectures offer comprehensive compute virtualization capabilities toaccommodate both native and third-party container hosting, so you cancontainerize and instantiate any application or network service and gainunprecedented value from your networks.
Directfrom Cisco, this is the complete guide to deploying and operatingcontainerized application and networkservices on Cisco platforms. First, the authors review essential virtualizationand containerization concepts for all network professionals and introduceleading orchestration tools. Next, they take a deep dive into containernetworking, introducing Cisco architectural support for containerinfrastructures. You'll find modular coverage of configuration, activation,orchestration, operations, and application hosting for each key Cisco softwareplatform: IOS-XE, IOS-XR, and NX-OS.
Theauthors explore diverse orchestration tools, including LXC, Docker, andKubernetes, and cover both Cisco and open-source tools for building and testingapplications. They conclude with multiple use cases that show howcontainerization can improve agility and efficiency in a wide range of networkenvironments.
