Networking
Octos Cloud provides a complete software-defined networking stack with zero egress fees and zero bandwidth caps. Build isolated environments, control traffic flow, and manage DNS — all from the portal.
Architecture overview
Internet
│
├── Public Network (auto-assigned public IP)
│ │
│ Virtual Router

│ Private Network (10.x.x.x)
│ ├── Instance-1
│ ├── Instance-2
│ └── Instance-3

└── Floating IPs (portable, reassignable)
Network types
| Type | Description | Use case |
|---|---|---|
| Public | Internet-routable, auto-assigned IPs | Web servers, APIs |
| Private (Isolated) | L2-isolated within your project | Internal services, databases |
| Shared | Shared across projects (admin-managed) | Multi-project architectures |
| VPC | Virtual Private Cloud with subnet control | Enterprise environments |
Security groups
Stateful firewall rules that control traffic at the Instance level.
Default behavior
- All inbound traffic is denied by default
- All outbound traffic is allowed by default
Common rule sets
Web server
| Direction | Protocol | Port | Remote |
|---|---|---|---|
| Inbound | TCP | 22 | Your IP |
| Inbound | TCP | 80 | 0.0.0.0/0 |
| Inbound | TCP | 443 | 0.0.0.0/0 |
Database server (private only)
| Direction | Protocol | Port | Remote |
|---|---|---|---|
| Inbound | TCP | 5432 | 10.0.0.0/24 |
| Inbound | TCP | 22 | Bastion IP |
Load balancers
Distribute traffic across multiple Instances for high availability.
- Navigate to Load Balancers in your project
- Click Create Load Balancer
- Configure listeners (port, protocol, health checks)
- Add target Instances to the backend pool
DNS management
Manage DNS zones and records directly from the Octos Cloud portal.
Supported record types
A · AAAA · CNAME · MX · TXT · SRV · NS · LOC
Create a DNS zone
- Navigate to DNS Management
- Click Create DNS Domain
- Add your domain and configure nameserver records
- Add individual records (A, CNAME, MX, etc.)
Zero egress — no transfer fees
Octos Cloud does not charge for:
- Outbound data transfer to the internet
- Traffic between Instances on the same Virtual Network
- API requests to the management plane
- DNS query resolution
This makes total cost of ownership significantly more predictable compared to hyperscalers that charge per-GB egress.
