Multiple Choice

A developer is working on an ecommerce website. The developer wants to review server logs without logging in to each of the application servers individually. The website runs on multiple Amazon EC2 instances, is written in Python, and needs to be highly available. How can the developer update the application to meet these requirements with MINIMUM changes?

• A) Rewrite the application to be cloud native and to run on AWS Lambda, where the logs can be reviewed in Amazon CloudWatch.
• B) Set up centralized logging by using Amazon Elasticsearch Service (Amazon ES), Logstash, and Kibana.
• C) Scale down the application to one larger EC2 instance where only one instance is recording logs.
• D) Install the unified Amazon CloudWatch agent on the EC2 instances. Configure the agent to push the application logs to CloudWatch.
