Question

A company has mounted sensors to collect information about environmental parameters such as humidity and light throughout all the company's factories. The company needs to stream and analyze the data in the AWS Cloud in real time. If any of the parameters fall out of acceptable ranges, the factory operations team must receive a notification immediately. Which solution will meet these requirements?

Accepted Answer

Option C meets every requirement with the simplest, most appropriate architecture:

1. **Real-time streaming**: Amazon Kinesis Data Streams is purpose-built for real-time data ingestion. It provides sub-second latency, allowing data to be consumed as soon as it arrives — unlike Kinesis Data Firehose which buffers data (minimum 60 seconds).

2. **Real-time analysis**: AWS Lambda can be configured as a consumer of a Kinesis data stream via an event source mapping. Lambda polls the stream and invokes your function with batches of records in near real-time. Inside the Lambda function, you can implement threshold-checking logic (e.g., humidity > 80%, light < 100 lux) with minimal code.

3. **Immediate notification**: Amazon SNS is the standard AWS service for push-based notifications. It suppor
