AWS Certified Big Data - Specialty (#8)

A large oil and gas company needs to provide near real-time alerts when peak thresholds are exceeded in its pipeline system. The company has developed a system to capture pipeline metrics such as flow rate, pressure, and temperature using millions of sensors. The sensors deliver to AWS IoT. What is a cost-effective way to provide near real-time alerts on the pipeline metrics?

Create an AWS IoT rule to generate an Amazon SNS notification.
Store the data points in an Amazon DynamoDB table and poll if for peak metrics data from an Amazon EC2 application.
Create an Amazon Machine Learning model and invoke it with AWS Lambda.
Use Amazon Kinesis Streams and a KCL-based application deployed on AWS Elastic Beanstalk.
