## How Points of Presence Work
|
||||
|
||||
### Geographic Routing
|
||||
<Steps>
|
||||
<Step title="Ingress Routing">
|
||||
Request is routed to the closest available point of presence. If one goes down, there is always another point available.
|
||||
</Step>
|
||||
|
||||
When a user requests access to your application:
|
||||
<Step title="Authentication">
|
||||
User identity is verified at the point of presence before getting routed to your backend.
|
||||
</Step>
|
||||
|
||||
1. **DNS Resolution**: The user's request is automatically routed to the closest available point of presence
|
||||
2. **Authentication**: The point of presence verifies the user's identity and permissions
|
||||
3. **Tunnel Routing**: Authenticated requests are sent through secure tunnels to your applications
|
||||
4. **Response Delivery**: Responses follow the same path back to the user
|
||||
<Step title="Tunnel Selection">
|
||||
Pangolin selects the optimal tunnel route to your backend service. Site tunnel clients (Newt) connect to the optimal point of presence.
|
||||
</Step>
|
||||
|
||||
<Check>
|
||||
This routing happens automatically and transparently - users always get the best possible performance without any manual configuration.
|
||||
</Check>
|
||||
|
||||
### Automatic Failover
|
||||
|
||||
Pangolin's points of presence provide built-in high availability:
|
||||
|
||||
- **Health Monitoring**: Each point of presence continuously monitors its health and connectivity
|
||||
- **Automatic Failover**: If one location becomes unavailable, traffic automatically routes to the next closest location
|
||||
- **Load Distribution**: Traffic is automatically balanced across multiple locations to prevent overload
|
||||
- **Global Redundancy**: Multiple points of presence ensure your applications remain accessible during regional outages
|
||||
<Step title="Failover Handling">
|
||||
If the primary tunnel fails, traffic automatically switches to an alternative route.
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||

Provide ingress to thin-clients on private networks via tunnels.
|

</Card>
|
||||
|
||||
- **Fault Tolerance**: No single point of failure - if one location goes down, others remain available
|
||||
- **Automatic Recovery**: Failed locations are automatically bypassed and traffic is rerouted
|
||||
- **Regional Redundancy**: Multiple locations per region provide additional redundancy

### Security and Compliance

|

Multiple points of presence ensure your applications remain accessible during regional outages.
|
||||
</Card>
|
||||
|
||||
- **Distributed Security**: Security controls are enforced at every point of presence
|
||||
- **Regional Compliance**: Points of presence can be configured to meet regional data requirements
|
||||
- **Encrypted Transit**: All traffic between points of presence and your applications is encrypted
|
||||
|
||||
### Scalability
|
||||
|
||||
- **Automatic Scaling**: New points of presence are automatically added as needed
|
||||
- **Load Balancing**: Traffic is distributed across multiple locations to handle high volumes
|
||||
- **Global Distribution**: Support for applications with users worldwide
|
||||
<Card title="Fault Tolerance" icon="shield">
|

## Deployment Models
|
||||
|
||||
### Pangolin Cloud
|
||||
|
||||
Pangolin Cloud includes a global network of points of presence that provide:
|
||||
|
||||
- **Automatic Management**: Points of presence are automatically deployed, monitored, and maintained
|
||||
- **Global Coverage**: Strategic locations worldwide for optimal performance
|
||||
- **Built-in High Availability**: Multiple redundant locations ensure 99.9%+ uptime
|
||||
- **Zero Configuration**: No setup or management required on your part
|
||||

|
||||
|
||||
### Self-Hosted Pangolin
|
||||
<Card title="Hybrid" icon="circle-nodes" href="mailto:numbat@fossorial.io">
|
||||
Host your own multiple points of presence with cloud coordination and automatic failover. Data always transits yours servers.
|
||||
</Card>
|
||||
|
||||
Self-hosted Pangolin operates as a single point of presence:
|
||||
|
||||
- **Single Location**: Your Pangolin instance serves as the only entry point
|
||||
- **Limited Availability**: No built-in redundancy - if your server goes down, access is lost
|
||||
- **Manual Management**: You're responsible for server maintenance and uptime
|
||||
- **Regional Limitation**: Performance depends on your server's location
|
||||
<Card title="Self-Hosted" icon="server" href="/self-host/quick-install">
|
||||

|
||||
</CardGroup>
|
||||
|
||||
<Warning>
|
||||
Self-hosted Pangolin provides only a single point of presence and is not highly available. Consider Pangolin Cloud or hybrid deployment for production environments requiring high availability.
|
||||
</Warning>
|
||||
|
||||
### Hybrid Deployment
|
||||
|
||||
Hybrid deployment allows you to host your own points of presence while leveraging Pangolin's cloud coordination:
|
||||
|
||||
- **Your Infrastructure**: Host points of presence on your own servers or cloud infrastructure
|
||||
- **Cloud Coordination**: Pangolin Cloud handles failover logic and coordination between your points of presence
|
||||
- **Automatic Failover**: If your points of presence go down, traffic automatically fails over to Pangolin Cloud
|
||||
- **Data Control**: Traffic flows through your servers, giving you control over data transit costs and privacy
|
||||
- **Custom Locations**: Deploy points of presence in specific regions or data centers of your choice
|
||||
|
||||
<Tip>
|
||||
Hybrid deployment is ideal for organizations that need high availability while maintaining control over their infrastructure and data transit.
