## Overview

Amazon CloudFront is a fast, globally distributed content delivery network (CDN). Cache content at edge locations worldwide to reduce latency, improve performance, and provide high availability with DDoS protection.

## When to Use

- Static website hosting and assets
- API acceleration and dynamic content
- Video and media streaming
- Mobile application content
- Large file downloads
- Real-time data distribution
- DDoS protection for origins
- Origin isolation and security

## Quick Start

Minimal working example:

```bash
# Create distribution for S3 origin
aws cloudfront create-distribution \
  --distribution-config '{
    "CallerReference": "myapp-'$(date +%s)'",
    "Enabled": true,
    "Comment": "My application distribution",
    "Origins": {
      "Quantity": 1,
      "Items": [{
        "Id": "myS3Origin",
        "DomainName": "mybucket.s3.us-east-1.amazonaws.com",
        "S3OriginConfig": {
          "OriginAccessIdentity": "origin-access-identity/cloudfront/ABCDEFG1234567"
        }
      }]
    },
    "DefaultCacheBehavior": {
      "AllowedMethods": {
        "Quantity": 3,
        "Items": ["GET", "HEAD", "OPTIONS"]
      },
      "ViewerProtocolPolicy": "redirect-to-https",
      "TargetOriginId": "myS3Origin",
      "ForwardedValues": {
        "QueryString": false,
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Use Origin Access Identity (OAI) for S3
- Enable HTTPS only for viewers
- Compress content at CloudFront
- Set appropriate cache TTLs
- Use cache invalidation cautiously
- Enable WAF for protection
- Monitor CloudWatch metrics
- Use multiple origins for redundancy

### ❌ DON'T

- Make S3 buckets public
- Cache sensitive data
- Use HTTP for production
- Ignore cache headers
- Create excessive invalidations
- Skip WAF protection

appbuilder-action-scaffolder

Included

Create, implement, deploy, and debug Adobe Runtime actions with consistent layout, validation, and error handling. Use this skill whenever the user needs to add actions to an App Builder project, understand action structure (params, response format, web/raw actions), configure actions in the manifest, use App Builder SDKs (State, Files, Events, database), deploy and invoke actions via CLI, debug action issues, or implement patterns such as webhook receivers, custom event providers, journaling consumers, large payload redirects, action sequence pipelines, and Asset Compute workers. Also trigger when users mention serverless functions in Adobe context, action logging, IMS authentication for actions, or cron-style scheduled actions.
