# 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.
