Figure 2. Goal of Organizations: Comprehensive Automation of Infrastructure

Tasks that can be automated include:

●

Autodiscovery and provisioning of devices

●

Role-based and policy-based management of infrastructure

●

Configuration management, event management, power management, and availability management of all

devices and their components

●

Autodiscovery of all components of a device, such as chassis, servers, fans, modules, memory units, and

disks

●

Dynamic provisioning of device resources (interfaces, VLANs, switch and port profiles, routes, etc.)

●

Inventory, operation, and licensing status reports for all devices

●

Continuous monitoring of resource utilization and capacity

Network automation is a crucial aspect of this comprehensive automation strategy. Features such as POAP and

intent-based automation with the Puppet and Chef tools dramatically reduce network deployment and configuration

times. Programming tools such as Python scripting and APIs such as Cisco NX-API enables instantaneous

provisioning and automated monitoring through integration with existing tools and frameworks.

Development and Operations Models and Continuous Integration

Development and operations (DevOps) models of software development and deployment, with their agility in

deploying new features and patches and their resulting business benefits, have become increasingly popular over

the past few years. DevOps environments enable rapid enhancement and tuning of applications with continuous

deployments: applications with rates ranging from tens of deployments per day to thousands of deployments per

day, depending on the application and organization. With this rate of change, to enable a DevOps model,

automation of infrastructure operations and management is not just desirable but required. Network devices, as

critical parts of the infrastructure, need to support automation and programmability features.
