Question

An Internet-of-Things (IoT) company is planning on distributing a master sensor in people's homes to measure the key metrics from its smart devices. In order to provide adjustment commands for these devices, the company would like to have a streaming system that supports ordered data based on the sensor's key, and also sustains high throughput messages (thousands of messages per second).

As a solutions architect, which of the following AWS services would you recommend for this use-case?

a. AWS Lambda
b. Amazon Simple Notification Service (SNS)
c. Amazon Simple Queue Service (SQS)
d. Amazon Kinesis Data Streams (KDS)

Answer 1

The appropriate AWS service for an IoT company to stream ordered data and support high message throughput is Amazon Kinesis Data Streams (KDS), designed for high volume real-time data processing and analysis.

Step-by-step explanation:

For an IoT company that needs to handle streaming of data with ordered messages and support for high throughput, the most suitable AWS service is Amazon Kinesis Data Streams (KDS). This service is designed to collect, process, and analyze real-time data streams with ease. It can handle hundreds of thousands of sources with data rates of several terabytes per hour, ensuring that data is placed in ordered sequences according to the sensor's key (partition key in KDS terms). Moreover, KDS supports real-time data processing with sub-second latencies, which is vital for providing immediate adjustment commands to smart devices.
