Objective

Use DynamoDB to have a centralized location flag variable that can be accessed from multiple EC2 instances

Steps

1. Create DynamoDB table, call it GlobalVariable.
2. Primary key: name = id, type = number
3. Sort key field: name = flag, type = String
4. Add item to table using your value with key id # - example below uses 42.
