This document provides an introduction to GÉANT and its Cloud Peering service. GÉANT operates a pan-European research and education network that interconnects National Research and Education Networks (NRENs) across Europe. It also manages a portfolio of services to support collaboration. The Cloud Peering service allows cloud providers to connect directly to GÉANT's network or through local NRENs to reach research communities. Options for connection include going through an NREN, direct peering at a GÉANT point of presence, or at an internet exchange. Costs vary depending on the connection method and capacity.
