Why choose Xelon Cloud?

Overview

Xelon Software Defined Networking (SDN) provides programmable virtual networks with Layer 2 VLANs, Layer 3 routing, and stateful firewall rules. Design complex network topologies via UI or API with zero physical hardware changes.

Key Highlights:

  • 802.1Q VLAN tagging with up to 4094 VLANs per tenant

  • Private subnets (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)

  • Stateful firewall rules (allow/deny inbound/outbound traffic)

  • BGP routing for multi-cloud and hybrid cloud connectivity

  • VPN tunnels (IPsec, OpenVPN, WireGuard) for site-to-site or remote access

  • Network ACLs (access control lists) at subnet level

Use Cases:

  • Multi-Tier Applications: Isolate web tier, app tier, database tier on separate VLANs

  • Compliance Segmentation: Separate production, dev, and test environments for PCI-DSS/HIPAA

  • Hybrid Cloud: Extend on-premise networks to Xelon Cloud via IPsec VPN or BGP

  • Zero Trust Networking: Micro-segmentation with per-VM firewall rules

Technical Specifications

Technical Specifications

VLANs & Subnets

  • VLAN IDs: 1-4094 (802.1Q standard), isolated Layer 2 broadcast domains

  • Private Subnets: RFC 1918 addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)

  • Subnet Sizes: /16 to /29 (256 IPs to 4 IPs per subnet)

  • DHCP: Built-in DHCP servers for automatic IP assignment

Firewall Rules

  • Stateful Inspection: Track connection state (NEW, ESTABLISHED, RELATED)

  • Rules: Allow/deny traffic by protocol (TCP/UDP/ICMP), port, source/destination IP/CIDR

  • Default Policy: Deny-all inbound, allow-all outbound (customizable per VM)

  • Rule Limit: Up to 500 firewall rules per VM

Routing

  • Static Routes: Configure static routes to route traffic between VLANs or external networks

  • BGP: Announce prefixes to external peers (on-premise routers, cloud providers)

  • VPN Routing: Route traffic through IPsec/OpenVPN/WireGuard tunnels

VPN Options

  • IPsec Site-to-Site: IKEv2 with AES-256-GCM encryption for hybrid cloud

  • OpenVPN: Remote access VPN with certificate-based authentication

  • WireGuard: Modern VPN protocol with 3x faster throughput than IPsec

Network Performance

  • Bandwidth: 1 Gbps - 10 Gbps per VM (no bandwidth throttling)

  • Latency: Sub-millisecond intra-datacenter latency (<0.5ms between VMs in same VLAN)

  • Throughput: Line-rate forwarding with hardware-accelerated virtual switches

High Availability

  • Redundant Switches: Active-active virtual switch pairs for zero downtime

  • Failover: Automatic failover on switch failure (<5 seconds)
