Chapter 19 - Caching Overview

Question 1

Caching

Answer 1

• We want to add security to that static website.
• It’s not supported by only using S3.
• We have to front that S3 website with a CloudFront distribution, and CloudFront as we recall, uses HTTPS natively, that is built right in.
• When given a situation that compares one solution to the other, if one has a cache and the other doesn’t, we want to focus on the one that includes a caching option.
• We just want to know, okay, is there an appropriate cache in front of the part of the architecture where it should be?
• Are we using the correct kind of cache in front of the database?

Question 2

Global Accelerator

Answer 2

On the exam, If you see a scenario that’s talking about IP caching, you should immediately be thinking Global Accelerator.

Global Accelerator gives you those 2 static IP addresses, that way customers can cache those IP addresses

And when the architecture behind them rotates such as the load balancer changing out or you’re failing from one region to another, it doesn’t really matter for your end user.

They still hit those two global accelerator IP addresses and everything’s good.
