A company is planning on using Amazon Kinesis firehose to stream data into an S3 bucket. They need the data to be transformed first before it can be sent to the S3 bucket. Which of the following would be used for the transformation process?

Answer options:

A.AWS SQS
B.AWS Lambda
C.AWS EC2
D.AWS API Gateway

Answer – B
The AWS Documentation mentions the following.
Kinesis Data Firehose can invoke your Lambda function to transform incoming source data and deliver the transformed data to destinations. You can enable the Kinesis Data Firehose data transformation when you create your delivery stream.
Option A is incorrect because SQS is a queue service and can not transform the data.
Option C is incorrect because although with EC2 instances, you can achieve the desired result, you need to manage and provision the server. Lambda is a better option.
Option D is incorrect because an API gateway is used to make API calls and not transform it.
