An IT company is working on client engagement to build a real-time data analytics tool for the Internet of Things (IoT) data. The IoT data is funneled into Amazon Kinesis Data Streams which further acts as the source of a delivery stream for Amazon Kinesis Firehose.

They noticed that data is not reaching Kinesis Firehose as expected.
