Global Accelerator

Question 1

Which AWS service is designed to improve global network performance by offering entry points onto the global AWS transit network as close to customers as possible using anycast IP addresses?

Answer 1

AWS Global Accelerator

Question 2

What is the primary purpose of AWS Global Accelerator?

Answer 2

To optimize traffic flow from users to AWS infrastructure, providing fewer hops and significantly improving performance

Question 3

What is provided at each AWS Global Accelerator Edge Location?

Answer 3

A pair of anycast IP addresses
(e.g., 1.2.3.4 and 4.3.2.1)

Question 4

Does AWS Global Accelerator route traffic directly through the AWS Global Network?

Answer 4

Not initially, traffic first travels over the public internet to the nearest Edge Location, where it transitions to the AWS Global Network

Question 5

How do anycast IP addresses enhance AWS Global Accelerator performance?

Answer 5

Unlike unicast IPs, anycast IPs can map to multiple Edge Locations, automatically routing traffic to the nearest one

Question 6

How does AWS CloudFront differ from AWS Global Accelerator?

Answer 6

• CloudFront: Brings content (data) closer to users with caching (CDN), and as a web product it works ONLY with HTTP/HTTPS protocols
• Global Accelerator: Reduces network hops by routing traffic through the AWS Global Network, and as network product it can work with HTTP/HTTPS and TCP/UDP protocols

Question 7

When should CloudFront be used over Global Accelerator?

Answer 7

CloudFront should be used when requirements are to improve content delivery through caching

Question 8

When should Global Accelerator be used over CloudFront?

Answer 8

Global Accelerator should be used when requirements are to optimize network performance by reducing latency and hops
