EMR Quiz
You have a set of IIS Servers running on EC2 Instances. You want to collect and process the log files generated from these IIS Servers. Which of the below services is ideal to run in this scenario?
A. Amazon S3 for storing the log files and Amazon EMR for processing the log files.
B. Amazon S3 for storing the log files and EC2 Instances for processing the log files.
C. Amazon EC2 for storing and processing the log files.
D. Amazon DynamoDB to store the logs and EC2 for running custom log analysis scripts.
A. Amazon S3 for storing the log files and Amazon EMR for processing the log files.
Amazon EMR is a managed cluster platform that simplifies running big data frameworks, such asApache HadoopandApache Spark, on AWS to process and analyze vast amounts of data. By using these frameworks and related open-source projects, such as Apache Hive and Apache Pig, you can process data for analytics purposes and business intelligence workloads. Additionally, you can use Amazon EMR to transform and move large amounts of data into and out of other AWS data stores and databases, such as Amazon Simple Storage Service (Amazon S3) and Amazon DynamoDB.
Options B and C, though partially correct would be an overhead for EC2 Instances to process log files when you already have a ready made service to help in this regard.
Option D is in invalid because DynamoDB is not an ideal option to store log files.
