A company has developed a book reading application deployed in AWS. As the number of users grows, there is an increasing need to add a search feature for the application. The team needs to create this feature as soon as possible under an independent pipeline in AWS CodePipeline. In the new pipeline, the source stage is a CodeCommit repository which contains the JSON format data used for the search service. The build stage has used AWS CodeBuild to configure the data. What is the best way to implement the search feature in AWS?

Answer options:

A.Use AWS CloudSearch to implement this search function. The build stage builds a CloudFormation template. Add another deploy stage to deploy the CloudFormation stack for the CloudSearch search domain.
B.Use AWS EC2 to provision and manage a cluster of servers running SOLR applications for the search feature. The build stage is responsible for baking an AMI.
C.Use AWS CloudSearch to implement this feature. The build stage uses AWS CLI to configure the data in the search domain of CloudSearch.
D.Use AWS Lambda to manage an EC2 Elasticsearch application for the search feature. The build stage is responsible for building the Lambda function.

Correct Answer – C
In this question, it mentions that a solution needs to be implemented as soon as possible. AWS CloudSearch should be considered first as it is a fully managed AWS service and users can easily set up and manage a search solution for a website or application. Check
https://docs.aws.amazon.com/cloudsearch/latest/developerguide/what-is-cloudsearch.html
for details.
Option A is incorrect: Because AWS CloudFormation does not support CloudSearch. To configure CloudSearch search domain, AWS CLI or ADK should be used.
Option B is incorrect: Because this solution is time-consuming and complicated. The team needs to have Solr knowledge in order to maintain such a system.
Option C is CORRECT: Because AWS CloudSearch is an appropriate tool to implement this feature. The AWS CLI aws cloudsearchdomain upload-documents can be used to upload JSON format data. Check the reference in
https://docs.aws.amazon.com/cloudsearch/latest/developerguide/uploading-data.html.
Option D is incorrect: Because it still needs an EC2 to implement Elasticsearch. In this case, options including CloudSearch should be considered.
