Question
To securely deliver static files globally, which AWS solution should be used?
A. Amazon Kinesis Data Streams
B. Amazon CloudFront with Amazon S3
C. Amazon EC2 instances with an Application Load Balancer
D. Amazon EFS
Answer
B. Amazon CloudFront with Amazon S3
Explanation
Amazon CloudFront with Amazon S3 provides a secure and fast way to globally deliver static files.
Amazon CloudFront combined with Amazon Simple Storage Service (S3) is the ideal solution for securely delivering static files globally. This setup leverages the strengths of both services to ensure high performance, scalability, and security.
Why Amazon CloudFront with Amazon S3?
Global Content Delivery
Amazon CloudFront is a Content Delivery Network (CDN) that caches content at edge locations worldwide. It reduces latency by delivering content closer to users, ensuring faster load times and a better user experience.
Security Features
CloudFront integrates with AWS Shield to protect against DDoS attacks and provides additional security features like signed URLs, signed cookies, and geo-restrictions to control access to your content.
Access to the S3 bucket can be restricted by allowing only requests routed through CloudFront, enhancing security.
Scalability and High Availability
S3 offers scalable storage for static files like images, videos, and web assets, while CloudFront handles traffic spikes by distributing load across its global edge network.
Cost Efficiency
Data transfer from S3 to CloudFront is free within AWS, and caching reduces repeated data retrieval from S3, lowering costs for high-volume traffic scenarios.
Ease of Integration
Both services integrate seamlessly, making it simple to configure and manage through the AWS Management Console or SDKs.
Why Not the Other Options?
A. Amazon Kinesis Data Streams: Designed for real-time data streaming and analytics, not for delivering static files.
C. Amazon EC2 Instances with an Application Load Balancer: While suitable for hosting applications or dynamic content, this setup is less efficient and costlier for delivering static files compared to using a CDN like CloudFront.
D. Amazon EFS (Elastic File System): EFS is a file storage service for shared access in applications but lacks global distribution capabilities required for efficiently delivering static content.
For securely delivering static files globally with low latency and high performance, the combination of Amazon CloudFront and Amazon S3 is unmatched. This solution is highly recommended in scenarios involving global content delivery or hosting static websites. This detailed explanation aligns with the AWS Certified Cloud Practitioner (CLF-C02) exam objectives and provides a comprehensive understanding of why this solution is optimal. Best of luck on your certification journey!
