A company has deployed a multi-tier web application to support a website. The architecture includes an Application Load Balancer (ALB) in public subnets, two Amazon Elastic Container Service (Amazon ECS) tasks in the public subnets, and a PostgreSQL cluster that runs on Amazon EC2 instances in private subnets.
The EC2 instances that host the PostgreSQL database run shell scripts that need to access an external API to retrieve product information. A solutions architect must design a solution to allow the EC2 instances to securely communicate with the external API without increasing operational overhead.

A company runs an application on Amazon EC2 instances across multiple Availability Zones in the same AWS Region. The EC2 instances share an Amazon Elastic File System (Amazon EFS) volume that is mounted on all the instances. The EFS volume stores a variety of files such as installation media, third-party files, interface files, and other one-time files.
The company accesses some EFS files frequently and needs to retrieve the files quickly. The company accesses other files rarely. The EFS volume is multiple terabytes in size. The company needs to optimize storage costs for Amazon EFS.
Which solution will meet these requirements with the LEAST effort?

An ecommerce company experiences a surge in mobile application traffic every Monday at 8 AM during the company's weekly sales events. The application's backend uses an Amazon API Gateway HTTP API and AWS Lambda functions to process user requests. During peak sales periods, users report encountering TooManyRequestsException errors from the Lambda functions. The errors result in a degraded user experience. A solutions architect needs to design a scalable and resilient solution that minimizes the errors and ensures that the application's overall functionality remains unaffected.

A company is building a new web application on AWS. The application needs to consume files from a legacy on-premises application that runs a batch process and outputs approximately 1 GB of data every night to an NFS file mount.
A solutions architect needs to design a storage solution that requires minimal changes to the legacy application and keeps costs low.
Which solution will meet these requirements MOST cost-effectively?

A company has developed an API by using an Amazon API Gateway REST API and AWS Lambda functions. The API serves static content and dynamic content to users worldwide. The company wants to decrease the latency of transferring the content for API requests. Which solution will meet these requirements?
