Cold Start Strategy
Overview
A cold start occurs when a new application container is created to handle increased traffic. During startup, the container needs time to initialize before it can receive requests.
Strategy
1. Keep Warm Containers
Maintain a small number of standby containers that are already running and ready to receive traffic immediately.
2. Auto Scaling
Automatically create additional containers when CPU usage, memory usage, or request rate exceeds predefined thresholds.
3. Lightweight Container Images
Use small Docker images to reduce image download and startup time.
4. Health Checks
Only send traffic to containers after they successfully pass health checks.
5. Container Image Caching
Cache frequently used container images on the compute nodes to avoid downloading them repeatedly.
Benefits
- Faster application startup
- Lower request latency
- Better user experience during traffic spikes
- Improved application availability
