Currently a company is using AWS DynamoDB since they want a serverless architecture and they don’t want to manage the underlying infrastructure. They use the DynamoDB service to ingest and store large amounts of metric related data. They now want to start storing a large number of log files which can be used for log analytics. Which of the following can be used for the storage of the log files?

Answer options:

A.AWS S3
B.AWS ElasticSearch
C.AWS Redshift
D.AWS DynamoDB

Answer – B
The AWS Documentation mentions the following
Amazon Elasticsearch Service (Amazon ES) is a managed service that makes it easy to deploy, operate, and scale Elasticsearch clusters in the AWS Cloud. Elasticsearch is a popular open-source search and analytics engine for use cases such as log analytics, real-time application monitoring, and clickstream analysis. With Amazon ES, you get direct access to the Elasticsearch APIs; existing code and applications work seamlessly with the service.
All other options are invalid since the best way to work with search capabilities is to use AWS ElasticSearch
