Learning Objectives
Amazon DynamoDB Accelerator (DAX) is a fully AWS managed service. It is an in-memory cache that can be used with DynamoDB tables to improve their performance by up to ten times. It works as a cluster with resources provisioned in different availability zones, making it a highly available service. Moreover, it supports Amazon VPC service, providing secure and easy DAX access to existing applications.
DAX automatically handles cache invalidations, data population, and cluster management. It also supports the existing DynamoDB API calls, so users can focus on innovation without worrying about making significant changes to the application. Moreover, it also reduces the read load on the DynamoDB tables by enabling the retrieval of cached data from itself, which can reduce the overall operational cost.

Your method is simple, straight to the point and I can practice with it everywhere, even from my phone, that's something I have never had in other learning platforms.
I highly recommend Educative. The courses are well organized and easy to understand.
I prefer Educative courses because they have a nice mix of text & images. I find that with full video courses, it can often be too easy to go into passive learning mode.
