Your company uses an application hosted in AWS which consists of EC2 Instances. The logs of the EC2 instances need to be processed and analyzed in real time , since this is a requirement from the IT Security department. Which of the following can be used to process the logs in real time?

Answer options:

A.Use Cloudwatch logs to process and analyze the logs in real time
B.Use Amazon Glacier to store the logs and then use Amazon Kinesis to process and analyze the logs in real time
C.Stream the logs to Kinesis Firehose and send the output to Kinesis analytics to process and analyze the logs in real time
D.Use another EC2 Instance with a larger instance type to process the logs

Answer – C
The AWS Documentation mentions the below
Real-time metrics and reporting
Amazon Kinesis Data Firehose is a fully managed service for delivering real-time streaming data to destinations such as Amazon Simple Storage Service (Amazon S3), Amazon Redshift, Amazon Elasticsearch Service (Amazon ES), and Splunk. Kinesis Data Firehose is part of the Kinesis streaming data platform, along with Kinesis Data Streams, Kinesis Video Streams, and Amazon Kinesis Data Analytics. With Kinesis Data Firehose, you don`t need to write applications or manage resources. You configure your data producers to send data to Kinesis Data Firehose, and it automatically delivers the data to the destination that you specified. You can also configure Kinesis Data Firehose to transform your data before delivering it.
Real-time data analytics
This combines the power of parallel processing with the value of real-time data. For example, process website clickstreams in real time, and then analyze site usability engagement using multiple different Kinesis Streams applications running in parallel.
Amazon Glacier is meant for Archival purposes and should not be used for storing the logs for real time processing.
