Global Networking | CloudNexus Infrastructure

Overview

CloudNexus Networking provides a globally distributed, software-defined network fabric that connects compute instances, storage volumes, and external endpoints with deterministic performance. Unlike traditional cloud providers that treat networking as a secondary concern, our infrastructure is built on a purpose-built 100Gbps optical backbone with anycast routing, ensuring sub-10ms packet delivery across 48 data center regions.

The platform abstracts complex routing protocols, firewall rules, and load balancing configurations into a unified control plane, while exposing full BGP, VLAN, and MACsec capabilities for enterprise network engineers who require granular control.

Core Features

Anycast Global Load Balancing

Single IP distributed across all edge locations. Traffic automatically routes to the nearest healthy node based on BGP path selection and real-time health checks.

Zero Config

Software-Defined Private Networks

Isolated virtual networks with customizable CIDR blocks, subnet routing tables, and peer connections between regions without traversing the public internet.

VPC Peering

DDoS Mitigation Layer

Always-on traffic scrubbing with 4.2 Tbps sinkhole capacity. L3/L4 volumetric filtering combined with L7 behavioral analysis to block application-layer attacks.

Enterprise Grade

Hardware-Accelerated Encryption

AES-NI and Intel QAT offload for TLS 1.3 and MACsec. End-to-end encryption with <5μs additional latency overhead per packet.

Zero Trust Ready

Custom BGP & Route Policies

Full access to route advertisement, AS-path prepending, community tags, and traffic engineering controls for hybrid cloud and on-prem integrations.

Advanced Routing

Real-Time Flow Analytics

sFlow, NetFlow v9, and IPFIX export to your SIEM. Sub-second visibility into bandwidth utilization, connection states, and geo-traffic distribution.

Observability

API & Infrastructure as Code

Manage network topology programmatically via REST API, CLI, or Terraform provider. Idempotent operations and state tracking ensure consistent deployments.

Technical FAQ

How does CloudNexus handle BGP route flapping and convergence?

We implement RFC 4724 (BGP Best-Practice Routing) with configurable dampening parameters, MED-based traffic engineering, and ECMP routing. Convergence times average 200-500ms, with automated failover to backup paths before packet loss occurs.

Can I bring my own AS number and peering relationships?

Yes. Enterprise plans support custom ASN allocation, direct physical/virtual peering via LACNIC/ARIN/RIPE, and private interconnect ports. Our NOC provides 24/7 routing assistance for complex multi-homed setups.

What encryption standards are supported for private network traffic?

Traffic between instances in the same region uses unencrypted virtual switching for performance. Cross-region and public-facing traffic supports MACsec (IEEE 802.1ae) with hardware offload, IPsec ESP mode, and mTLS 1.3. Key rotation is automated via HSM-backed KMS.

How is DDoS mitigation integrated with the load balancer?

Mitigation is transparent and always-on. The scrubbing centers sit upstream of the edge load balancers using BGP blackholeing and flow steering. Legitimate traffic is never dropped; only attack vectors are challenged via cryptographic cookies or rate-limited.
