Overview

Xloud Networking delivers software-defined connectivity for your cloud workloads. Every project receives its own isolated network plane — you define the topology, address space, routing policy, and access controls. Project networks remain fully isolated from one another and from the physical underlay unless you explicitly connect them through a router with an external gateway.
Prerequisites
  • An active Xloud account with appropriate permissions
  • Access to the Xloud Dashboard (https://connect.<your-domain>) or CLI configured with credentials
  • API credentials sourced (source admin-openrc.sh)

Key Concepts

ResourceDescription
NetworkAn isolated L2 broadcast domain. Instances attach to networks via virtual ports.
SubnetAn IP address range assigned to a network, with DHCP, gateway, and DNS configuration.
RouterAn L3 device that routes traffic between subnets and provides external gateway connectivity via NAT.
PortA virtual network interface connecting an instance or router to a network.
Floating IPA publicly routable address that maps to a port’s private IP via NAT on the router.
Security GroupA stateful, per-port firewall ruleset controlling ingress and egress traffic.
Start with the simplest topology that meets your requirements: one network, one subnet, one router with an external gateway, and a security group. Expand from there as your workload grows.

Networking Topics

Create a Network

Provision an isolated project network and configure its IP address space with a subnet

Create and Manage Subnets

Add subnets, configure DHCP allocation pools, DNS resolvers, and host routes

Routers and Gateways

Connect project subnets to the internet with L3 routers and external gateways

Floating IP Addresses

Allocate public IPs from the external pool and associate them with instances

Network Security Groups

Define stateful firewall rules controlling ingress and egress traffic per instance port

DNS Configuration

Configure DNS name servers pushed to instances via DHCP for hostname resolution

Network Topologies

Reference architectures for three-tier, HA, and shared-services network designs

Troubleshooting

Diagnose and resolve connectivity, floating IP, and DHCP issues
