Bare Metal servers bill outgoing (egress) traffic per GB of data leaving through the public network interface; traffic through a private network interface is not billed. Rates vary by location and are listed on the pricing page.

Traffic between servers in the same data center

Two servers in the same data center communicating through public IP addresses generate billed egress. The traffic passes through the public network layer regardless of physical proximity. To avoid these charges, route server-to-server traffic through a private network interface instead:
  • Attach a private network at server creation — Gcore Cloud supports both a public and a private interface on the same Bare Metal server.
  • Use private IPs for communication between Bare Metal servers and between Bare Metal servers and Virtual Machines in the same region.
  • Reserve public IPs for servers that handle requests from external clients.
