Which solution will meet these requirements MOST cost-effectively?

  • A. Store the logs in Amazon S3. Use Amazon Athena tor analysis.
  • B. Store the logs in Amazon RDS. Use a database client for analysis.
  • C. Store the logs in Amazon OpenSearch Service. Use OpenSearch Service for analysis.
  • D. Store the logs in an Amazon EMR cluster Use a supported open-source framework for SQL-based analysis.

Selected Answer: A
Scalable + "The solution must support queries with standard SQL" = A B not scalable C OpenSearch is like ElasticSearch so does not support SQL syntax D EMR is processing not storage. Map-Reduce can use SQL like syntax but this option does not solve scalable storage issues. You normally run EMR on some stored data

OpenSearch can support SQL queries, https://docs.aws.amazon.com/opensearch-service/latest/developerguide/sql-support.html

Amazon Athena is an interactive analytics service that makes it simple to analyze data in Amazon Simple Storage Service (S3) using SQL. Athena is serverless, so there is no infrastructure to set up or manage, and you can start analyzing data immediately. You don’t even need to load your data into Athena; it works directly with data stored in Amazon S3. Amazon Athena for SQL uses Trino and Presto with full standard SQL support and works with various standard data formats, including CSV, JSON, Apache ORC, Apache Parquet, and Apache Avro. Athena for Apache Spark supports SQL and allows you to use Apache Spark, an open-source, distributed processing system used for big data workloads. To get started, log in to the Athena Management Console and start interacting with your data using the query editor or notebooks.

Difficult question because both A and C meet the requirements. (OpenSearch does "support queries with standard SQL".) Still, native S3 storage is slightly cheaper than storage for OpenSearch. Also, Athena does not incur additional cost while OpenSearch does. Question asks for cost efficiency, thus A. D is out, not only because of the cost but also because you do not 'store logs in (!) an Amazon EMR cluster'; you can use (!) an EMR cluster to analyze data that is stored elsewhere.

And descriptions of both products, Athena as well as OpenSearch, state that you can use them to "analyze" data.

Seems that even cold storage is still more expensive than S3.

option D (using Amazon EMR with an open-source framework) may be overkill for the relatively simple SQL-based analysis.
