Networking consists of multiple buyer segments including Service Provider, Cloud Provider, Enterprise, and Residential. Each of these segments can be further broken down into sub segments.
Service Providers and Cloud providers are similar in that they both represent concentrated buying, and both have significant purchasing power. Service providers have traditionally made their revenue from network-based services, so network service intelligence is of significant importance to them. Cloud providers have traditionally made their revenue from computer-based services, so network service intelligence is lower priority to them. There is some overlap between Service Providers and Cloud Providers in areas such as peering and core routing. Telecom services providers and Cable Providers used to be significantly different segments. While they still use different technologies, and they have different cultures, the types of services they offer have increasing overlap including: voice, video, Internet, and business connectivity services. Some Cable Providers offer mobile services, often leveraging the infrastructure of a Service Provider, to do so.
The main concern of Enterprises is connecting their branches and campuses to each other, to their own data centers, and to cloud services. Enterprises utilize routers and switches on their own premises, with this network infrastructure often leverage Internet and Service Provider network infrastructure for full end-to-end connectivity. The extent of investment in network infrastructure varies across different sub segments including Large Enterprise, mid-market, and Small & Medium size business (SMB).
