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 model to facilitate collaboration between new cloud/SDDC team and existing functional teams (application, server, network and storage)
- Skills to support the new operational model and service-oriented approach
To gain an understanding of the concepts of a new IT operating model and why network and security should be part of it.
Different phases of NaaS Model
- Review the ITaaS and NaaS operating models
- Identify the capabilities required to deliver and operate NaaS
- Understand the journey to the NaaS operating model from both an operational and organizational standpoint
