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.
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?
