Question
A company needs a content delivery network that provides secure data, video, application, and API delivery to users globally with low latency and high transfer speeds. Which AWS service meets these requirements?
A. Amazon CloudFront
B. Elastic Load Balancing
C. Amazon S3
D. Amazon Elastic Transcoder
Answer
A. Amazon CloudFront
Explanation
Amazon CloudFront is a content delivery network (CDN) that integrates with other AWS services to deliver content with low latency and high transfer speeds globally.
Why Amazon CloudFront?
Amazon CloudFront is a content delivery network (CDN) service designed to securely deliver data, videos, applications, and APIs to users worldwide with low latency and high transfer speeds. It achieves this by utilizing a global network of edge locations and caching mechanisms that bring content closer to end users. Here’s why it fits the requirements:
Key Features of Amazon CloudFront
Global Edge Network
CloudFront has over 600 Points of Presence (PoPs) globally, ensuring data is delivered from the nearest location to reduce latency and improve speed.
High Performance
It provides low latency and high throughput by leveraging AWS’s backbone infrastructure for optimal routing.
Security
Offers SSL/TLS encryption, HTTPS support, and integration with AWS Shield for DDoS protection. It also supports field-level encryption and access controls like signed URLs or cookies to restrict unauthorized access.
Scalability
Automatically scales to handle varying traffic loads without compromising performance or security.
Use Cases
Ideal for delivering static and dynamic web content, streaming video (live or on-demand), API acceleration, software downloads, and more.
Why Not the Other Options?
B. Elastic Load Balancing (ELB): While ELB distributes incoming traffic across multiple targets (like EC2 instances), it does not provide caching or global edge locations for low-latency content delivery.
C. Amazon S3: S3 is a storage service for hosting static files but lacks the CDN capabilities needed for fast global delivery.
D. Amazon Elastic Transcoder: This service is used for converting media files into different formats but does not handle content delivery.
Amazon CloudFront is the best choice for a company needing a secure CDN to deliver data, videos, applications, and APIs globally with low latency and high transfer speeds. It aligns perfectly with the requirements outlined in the question.
