Concurrent with the challenges of adapting to these changes in the IT industry is the continued challenge for IT to 

do more with flat or decreasing budgets. This confluence of factors has caused IT managers to become eager to 

identify and adopt new technologies and solutions that deliver efficiency for those maintenance activities that are 

consuming more than three-quarters of staff time. The goal of IT managers is to deliver excellent maintenance 

service with less staff effort and increase the focus on deployment of new services for the organization. This trend 

is the focal point of evolving data center strategy. Therefore, enterprises are seeking data center solutions that 

deliver on the efficiency promises of unified infrastructure and management products. 

The adoption of converged infrastructure solutions, such as Cisco

®

 Unified Fabric and Cisco Unified Computing 

System

™

 (Cisco UCS

®

), has been increasing because converged infrastructure that spans computing, networking, 

and storage resources can improve IT agility, protect business investments into the future, streamline deployment, 

and significantly increase asset utilization. Converged infrastructure helps reduce floor space needs and energy 

costs and provides operation benefits by creating a virtualized pool of resources. However, the real reduction in the 

total cost of ownership (TCO) occurs when converged infrastructure is combined with end-to-end, simplified, 

automated management. 

Automation and programmability capabilities in the components of the data center - computing, networking, 

storage, and services resources - enable this end-to-end automated management. A modern network device, be it 

a switch or a router or a service appliance, has to support a wide range of automation features and provide robust 

APIs for external tools, both off-the-shelf and custom-built, to be able to automatically provision network resources, 

provide bandwidth allocation and latency guarantees to support network service-level agreements (SLAs), and 

monitor the network for performance and compliance needs. 

This document describes the various use cases for network automation and programmability and discusses the 

features of the Cisco Nexus

®

 9000 Series Switches that enable these use cases. 

IT as a Service 

IT is increasingly being delivered as a service, with private cloud models, to provide the speed, flexibility, and 

competitive innovation needed by modern businesses. IT as a service (ITaaS) aims to achieve these goals: 

● 

Accommodate rapid business growth without adding IT staff. 

● 

Standardize the IT environment while providing the capability to expand the size, scope, and scale of 

services delivered to customers. 

● 

Increase the customer base and global presence as a result of the nimbleness and agility of the IT 

environment. 

● 

Increase collaboration among the development and IT teams, resulting in new automation use cases to 

foster even greater innovation. 

ITaaS typically is implemented in several phases. 

The first phase of ITaaS implementation requires several building blocks: 

● 

Self-service portal and standardized menu of services 

● 

Service-delivery automation 

● 

Operation-process automation 

● 

Resource-management automation 

● 

Service lifecycle automation
