A company built an ecommerce website on AWS using a three-tier web architecture.The application is Java-based and composed of an Amazon CloudFront distribution, an Apache web server layer of Amazon EC2 instances in an Auto Scaling group, and a backend Amazon Aurora MySQL database.Last month, during a promotional sales event, users reported errors and timeouts while adding items to their shopping carts.The operations team recovered the logs created by the web servers and reviewed Aurora DB cluster performance metrics.Some of the web servers were terminated before logs could be collected and the Aurora metrics were not sufficient for query performance analysis.Which combination of steps must the solutions architect take to improve application performance visibility during peak traffic events?

A company hosts a data-processing application on Amazon EC2 instances.The application polls an Amazon Elastic File System (Amazon EFS) file system for newly uploaded files.When a new file is detected, the application extracts data from the file and runs logic to select a Docker container image to process the file.The application starts the appropriate container image and passes the file location as a parameter.The data processing that the container performs can take up to 2 hours.When the processing is complete, the code that runs inside the container writes the file back to Amazon EFS and exits.The company needs to refactor the application to eliminate the EC2 instances that are running the containers.Which solution will meet these requirements?Read More →

A company is deploying a distributed in-memory database on a fleet of Amazon EC2 instances.The fleet consists of a primary node and eight worker nodes.The primary node is responsible for monitoring cluster health, accepting user requests, distributing user requests to worker nodes, and sending an aggregate response back to a client.Worker nodes communicate with each other to replicate data partitions.The company requires the lowest possible networking latency to achieve maximum performance.Which solution will meet these requirements?Read More →

A company needs to aggregate Amazon CloudWatch logs from its AWS accounts into one central logging account.The collected logs must remain in the AWS Region of creation.The central logging account will then process the logs, normalize the logs into standard output format, and stream the output logs to a security tool for more processing.A solutions architect must design a solution that can handle a large volume of logging data that needs to be ingested.Less logging will occur outside normal business hours than during normal business hours.The logging solution must scale with the anticipated load.The solutions architect has decided to use an AWS Control Tower design to handle the multi-account logging process.Which combination of steps should the solutions architect take to meet the requirements?
