Blazor Pod Scheduling
C# Blazor Pod Scheduling Kubernetes Docker SignalR WebSocket Sticky Session HPA Health Check .NET 8 Razor Components
| Aspect | Blazor Server | Blazor WASM | Blazor United (.NET 8) |
|---|---|---|---|
| Render | Server (SignalR) | Browser (WASM) | ทั้งสอง (per component) |
| Sticky Session | ต้องใช้ | ไม่ต้อง | ขึ้นกับ Component |
| Image Size | 80-120MB | 20-30MB (Nginx) | 80-120MB |
| Resource | CPU+RAM มาก | น้อย (Static) | ปานกลาง |
| Scale | ซับซ้อน (Session) | ง่าย (Stateless) | ปานกลาง |
| Offline | ไม่ได้ | ได้ | บางส่วน |

- SignalR: ใช้ Redis Backplane สำหรับ Blazor Server Multi-pod
- Sticky: ตั้ง Cookie Affinity สำหรับ Ingress WebSocket
- WASM: ใช้ Brotli Compression ลด WASM Download Size 60%
- Health: ตั้ง Health Check ตรวจ DB Redis External API
- .NET 8: ใช้ Blazor United เลือก Render Mode ต่อ Component
