Challenges with network and security services 

Network and security were always the bottleneck of the infrastructure.

Below are the major pain points with rigid hardware defined infrastructure :

• Placement and mobility were limited by the physical port 
• Provisioning was slow due to lack of advanced automation capabilities, as it is not designed for automation
• It was operationally intensive and hardware-dependent

The following can be done to achieve IT as a service model:

• Cloud networking architectural and operational model support the evolution of IT as a service (ITaaS) model
• End-to-end visibility with real time monitoring and troubleshooting (across virtual and physical networks) for integrated network availability and performance management
• On-demand automated network provisioning and configuration to support rapid application deployment
• New organizational...
