Access DynamoDB DAX Cluster by installing sample application on EC2 Instance

Lab Details

This lab will show you how to create and configure a DynamoDB DAX Cluster within the Amazon cloud.

After you have practiced using Amazon Machine Images to launch Amazon EC2 Instances, you will then use key pairs for SSH authentication and log in to your instance. Next, you will create a Go app followed by a sample DynamoDB Table.

To track the DynamoDB table's timings, you will use the GetItem, Query and Scan commands. Then, run the command again with DAX Cluster to check the durations of GetItem and Query and Scan.

Duration: 60 minutes

AWS Region: US East, N. Virginia us-east-1

Introduction:

What is DynamoDB Accelerator? (DAX)

DynamoDB provides a single-digit millisecond response. Sometimes, however, the application may require a response in Microseconds.

DAX provides in-memory acceleration that reduces the response time of eventually consistent from single-digit milliseconds down to microseconds.

It can be run in a VPC environment. It creates a DAX Cluster by using Subnet and Security groups.

DynamoDB DAX: A Use Case

Software that requires the same data to be read over and over again

Applications that are cost-sensitive and require reading.

If your application does repeat read over large datasets.
