The Outbound connection between the Pelican gateway and its associated cloud server is always an HTTPS connection. This stands for Hypertext Transfer Protocol Secure. The important part is “Secure” because the HTTPS connection uses the Secure Socket Layer (SSL)/Transport Layer Security (TLS) protocol, which is basically a private point-to-point connection between two devices over the Internet.
Simply, an HTTPS connection makes it so no external devices are able to track the end-to-end connection points across the Internet, because they are secured using Public Key transfer.
