While each {ANYNODE} operates independently as a self-contained universal computing system, there are scenarios where interoperability among {ANYNODE}s is necessary, whether for edge, hybrid, or distributed computing setups. To address this need, we have Sky Link, also known as GPN (Global Private Network), which is an integral component of the built-in Sky Router system. It offers an exceptionally secure solution for establishing wide area network connections among {ANYNODE}s. Unlike traditional methods that extend network connections across entire clusters, Sky Link is meticulously designed to ensure all network traffic is exclusively routed through secure network tunnels. This architectural approach prioritizes security, offering precise control over which nodes can access a private network.
