Performance-Based Routing
Performance routing offers a more comprehensive approach. It takes into account not just latency, but also endpoint performance and health metrics. This method can be useful for complex applications with varying load conditions or global service distribution needs.
- Accounts for both network latency and server performance.
- Can dynamically adjust traffic flow based on endpoint health.
- Ideal for mission-critical applications that need high availability alongside low latency.
Note: Performance routing may offer better overall reliability by considering factors such as server load, resource availability, and current health, whereas latency routing strictly focuses on network speed.
Comparison Table
| Routing Type | Latency Consideration | Performance Factors | Use Case |
|---|---|---|---|
| Latency Routing | Yes | No | Real-time applications like gaming or live streaming |
| Performance Routing | Yes | Yes | Mission-critical applications requiring high availability and low latency |
When deciding between these two methods, consider whether your application can tolerate occasional performance dips due to factors beyond latency or if maintaining minimal network delay is the primary concern. For high-demand services, performance routing may offer a more balanced approach to ensure the best user experience under varying global conditions.
