I would like to know the difference between ISP connections and IX connections? Basically we are evaluating some of the ISPs to get our edge circuits. While doing some research on it, came across to peering connections to IX locations. How do they help us? When I search in peering database, companies are having ISP links as well as IX links. How do they use it? Any pointers will be helpful? Sorry if it is a beginner question, could not find the correct difference and usage of these two models.
The Internet is really just a bunch of networks connected together. Consumers and businesses connect to ISPs as customers. ISPs connect to other ISPs, either as customers of larger ISPs, or as peers at Internet Exchange Points (IXPs). At IXPs, ISPs can often peer with multiple other ISPs and CDNs, reducing costs by having a single location for connections, instead of running connections to multiple places in order to connect to multiple peers.
