A sensor within an IoT device can send data to a cloud service. For example, AWS IoT is a cloud service that can store data from IoT device sensors. Once that data is received, a service can write a DynamoDB table based on certain rules. DynamoDB is a non-relational database (NoSQL). To learn about how database rules operate, read AWS IoT Rules Tutorials. https://docs.aws.amazon.com/iot/latest/developerguide/iot-rules-tutorial.html)
Prompt
To complete this activity, you will want to go into the AWS Management Console through your AWS Academy account. You can do this by logging into AWS and starting your Learner Lab. Once in the AWS Management Console, select ‘DynamoDB’ under All Services, Database.
· Once you’re in the right console, follow the tutorial to create a rule for query statements in a non-relational database. The first step involves choosing “Act.”
· If you’re having issues accessing the Creating a Rule with a DynamoDB Action (https://docs.aws.amazon.com/iot/latest/developerguide/iot-ddb-rule.html) tutorial through AWS, use this link. Take screenshots to show your work.
After you have created the rule, test the rule using DynamoDB Action.
·
· Take screenshots to show your work.
· Write a reflection to address the following questions:
· What is an appropriate business scenario where a key-value document-based database like DynamoDB would be used?
· What’s a best practice for isolating frequently used items?
· When should you use a DynamoDB Rule compared to other rules, such as Lambda Action and SNS?
Guidelines for Submission
Your submission should be uploaded as a Word Document (.docx) that includes screenshots (at least 2 to 3) and your reflection.
