A developer is building an application on AWS. The application includes an AWS Lambda function that processes messages from an Amazon Simple Queue Service (Amazon SQS) queue.
The Lambda function sometimes fails or times out. The developer needs to figure out why the Lambda function fails to process some messages.
Which solution will meet these requirements with the LEAST operational overhead?
A developer has created an AWS Lambda function that is written in Python. The Lambda function reads data from objects in Amazon S3 and writes data to an Amazon DynamoDB table. The function is successfully invoked from an S3 event notification when an object is created. However, the function fails when it attempts to write to the DynamoDB table.
What is the MOST likely cause of this issue?
A website serves static content from an Amazon Simple Storage Service (Amazon S3) bucket and dynamic content from an application load balancer. The user base is spread across the world and latency should be minimized for a better user experience.
Which technology/service can help access the static and dynamic content while keeping the data latency low?
An application needs to use the IP address of the client in its processing. The application has been moved into AWS and has been placed behind an Application Load Balancer (ALB). However, all the client IP addresses now appear to be the same. The application must maintain the ability to scale horizontally.
Based on this scenario, what is the MOST cost-effective solution to this problem?
