This chapter provided a high-level overview of how the networks of today are causing challenges for organizations and their operations staff. It also covered the common business and IT trends that the industry is seeing and how they affects the networks of today. The overall benefits desired by organizations and their IT staff lead to the need to rethink the campus environment. Cloud applications and the influx of the amount of data within the network is causing strain on the network. This is causing organizations to look at ways to alleviate the pressure that is being put on the network and the organization as a whole. Security is no longer an afterthought; it is crucial to incorporate security into everything in the environment. This means that from concept to design to implementation, security must be thought of the entire way. The use cases introduced in this chapter will each be covered in depth in the upcoming chapters. Application performance, security, segmentation, improved user experience, redundancy, and resiliency are key drivers that point to an intent-based network infrastructure.
