To configure CloudFront caching for an SPA, implement distinct cache behaviors for static assets versus dynamic API responses. This ensures optimal performance by serving static content from S3 origins while routing API traffic to ALB origins for low latency delivery.

Securing an S3 origin using CloudFront is best achieved by implementing Origin Access Control (OAC). OAC restricts direct public access to your S3 buckets, ensuring that users can only access your static content through CloudFront CDN distributions.

Yes, you can use Lambda@Edge and CloudFront Functions for request and response manipulation at the edge. This approach allows you to execute custom logic closer to your users, modifying headers or rewriting URLs to achieve low latency and high availability.

WAF integration with CloudFront enhances security for dynamic content delivery by filtering malicious traffic at edge locations. This prevents malicious requests from reaching your ALB origins, protecting your APIs while maintaining high availability and low latency.

You need custom error pages in a CloudFront distribution when hosting Single Page Applications to handle client-side routing properly. Configuring custom error responses ensures that 404 errors return your application's index document, allowing the SPA router to handle the request.
