Domain 2.5: Performance — AWS SAP-C02 Practice Question 62

How to approach this question

Identify the service that provides global caching for HTTP APIs.

Full Answer

Deploy Amazon CloudFront and set the ALB as the origin., Configure Cache Behaviors in CloudFront to cache the API responses based on specific HTTP headers and query strings.

Amazon CloudFront is a global Content Delivery Network (CDN). By placing CloudFront in front of the ALB, API responses are cached at edge locations close to the users in Asia and Europe, providing single-digit millisecond latency. Because the data changes infrequently, this is highly effective. You must configure CloudFront Cache Behaviors to forward and cache based on query strings so that a request for Product A doesn't return the cached response for Product B.

Common mistakes

Choosing Global Accelerator, which improves routing but does not cache, meaning the EC2 instances would still handle every request.
