AWS Global Accelerator vs Amazon CloudFront

Correct Answer: C, D.

AWS Global Accelerator uses the highly available, high-speed AWS global network and anycast routing techniques to greatly improve the availability and network performance of the customer application.

By leveraging Edge Locations and edge infrastructure traffic to and from customer application endpoints ingresses and egresses the AWS global network at geographically closer locations to clients.

Amazon CloudFront is a content delivery network (CDN) that improves the performance of cacheable web content, like videos, images, using content caches at Edge Locations.

Option A is INCORRECT because Amazon CloudFront does not use Unicast techniques.

Instead, it uses a content caching mechanism in delivering enhanced web application performance.

Option B is INCORRECT because both AWS Global Accelerator and Amazon CloudFront service make use of Edge Locations and edge infrastructure on the AWS Global network.

Option E is INCORRECT because Global Accelerator provides static public IP addresses for the customer resource endpoints, whilst the fully-qualified domain name of the Amazon CloudFront distribution can resolve to dynamic public IP addresses.

AWS Global Accelerator and Amazon CloudFront are both AWS services that improve the performance, availability, and security of applications running on AWS or on-premises. While both services work towards achieving similar goals, they differ in several ways. Let's look at the two valid differences between AWS Global Accelerator and Amazon CloudFront:

A. AWS Global Accelerator uses the Anycast technique to accelerate latency-sensitive applications, while Amazon CloudFront uses Unicast.

AWS Global Accelerator uses Anycast, a network addressing and routing methodology, to direct traffic to the optimal AWS endpoint. Anycast allows AWS to advertise the same IP address from multiple locations worldwide, and the traffic is automatically routed to the nearest AWS endpoint with the lowest latency.

On the other hand, Amazon CloudFront uses Unicast to distribute content from the edge locations to the users. Unicast is a traditional method that sends packets from one sender to one receiver.

B. Amazon CloudFront makes use of Edge Locations and edge infrastructure, while AWS Global Accelerator does not.

Amazon CloudFront is a content delivery network (CDN) service that uses a global network of edge locations to deliver static and dynamic web content to end-users. The edge locations are geographically distributed and cache content closer to the users, reducing the latency and increasing the performance of the applications.

In contrast, AWS Global Accelerator uses Anycast to route traffic to the optimal AWS endpoint, without caching the content at the edge locations. AWS Global Accelerator is designed to accelerate the traffic for a wide range of applications, including those that are not HTTP-based, such as gaming, VoIP, and IoT.

C. AWS Global Accelerator does not include the content caching capability that Amazon CloudFront does.

This option is incorrect. AWS Global Accelerator does not cache content at the edge locations, but it uses the Anycast technique to route traffic to the optimal AWS endpoint, improving the performance of the applications.

D. AWS Global Accelerator is suitable for applications that are non-HTTP/S, such as VoIP, MQTT, and gaming, whereas Amazon CloudFront enhances the performance of HTTP-based content such as dynamic web applications, images, and videos.

AWS Global Accelerator is designed to accelerate the traffic for a wide range of applications, including those that are not HTTP-based, such as gaming, VoIP, and IoT. AWS Global Accelerator improves the performance of any TCP-based application that requires a stable and reliable network connection, regardless of the protocol or port.

In contrast, Amazon CloudFront is a content delivery network (CDN) service that is designed to improve the performance of HTTP-based content, such as dynamic web applications, images, and videos.

E. For the resource endpoint, Amazon CloudFront offers static public IP addresses, while AWS Global Accelerator does not.

This option is incorrect. Both AWS Global Accelerator and Amazon CloudFront support the use of static IP addresses for the resource endpoint. AWS Global Accelerator provides static anycast IP addresses, and Amazon CloudFront provides static IP addresses for the origin server.
