Traditional networks use manual configuration and management mechanisms. The command-line interface (CLI), 

an interface designed for interactive human use, is the primary mechanism in such networks. The range of 

automation needed for a private cloud deployment, however, cannot be accomplished with the CLI and Simple 

Network Management Protocol (SNMP)-based scripts and tools. To help IT environments transition from human-

led network operations to automated network operations, IT needs: 

● 

New network automation capabilities such as Power-On Auto Provisioning (POAP) and intent-led 

automation using the Puppet and Chef tools 

● 

Programming capabilities such as Representational State Transfer (REST) and JavaScript Object Notation 

(JSON)-based interfaces 

● 

APIs with comprehensive language support 

After implementing a private cloud infrastructure, IT departments focus on implementing chargeback models that 

allow business units to allocate, account for, monitor, and report resource use and associated costs. Business units 

get visibility into the amount they are paying for resources and the amount of their resources that is unused, 

allowing them to optimize resource consumption and costs. Such self-service optimizations depend on automation 

capabilities in the network: automated resource tracking and reporting with detailed statistics and analytics, 

automated resource provisioning and deprovisioning, automated tuning of quality-of-service (QoS) capabilities, etc. 

As IT departments move from these private cloud ITaaS models to hybrid cloud models that use capacity bursting 

and cloud-based disaster recovery, automation features become even more important: to enable automated 

capacity management, workload mobility, and disaster recovery. Automated VLAN and Virtual Extensible LAN 

(VXLAN), route injection, security configuration, analytics collection, and error reporting are critical for successful 

hybrid cloud deployment. In addition, programmability features with comprehensive API and language support are 

needed for different orchestration and management frameworks in the public and private cloud domains to enable 

automatic configuration and management of the network. 

Infrastructure Provisioning and Operations 

Organizations endeavor to automate every aspect of their infrastructure: bare-metal, virtualized computing, 

networking, and storage resources and services (Figure 2). Automation of infrastructure provisioning can bring 

immense benefits by reducing the infrastructure light-up time: the amount of time that capital investments stay 

unused. This strategy also allows time-consuming, error-prone manual tasks to be replaced by automated tasks 

that are completed in dramatically faster times with increased accuracy. Similarly, after the infrastructure is 

operational, automation of day-to-day management, monitoring, and configuration changes can increase the 

efficiency of infrastructure operations teams.
