How should the developer update the application to improve the application’s resiliency?
Revise the request content in the application code.
Use the AWS SDK for Java to interact with AWS APIs.
Scale out the application so that more instances of the application are running.
Add additional logging to the application code.
Explanations:
Revising the request content may help with specific errors, but it does not address underlying issues in handling responses or connection stability. Simply changing the content does not ensure resiliency against service errors or unexpected issues.
Using the AWS SDK for Java provides built-in error handling, retries, and exponential backoff for API calls. This increases the application’s resilience against temporary errors from AWS services, which is crucial when dealing with 5xx errors.
Scaling out the application may help with performance issues, but it does not inherently resolve the 5xx errors related to AWS service requests. If the root cause is not addressed, additional instances may still experience the same errors.
While additional logging can help identify issues, it does not improve the application’s resiliency. Without addressing the actual error handling and retries in the HTTP requests, the 5xx errors will still occur, affecting user experience.
As I see it, the answer is:
Use the AWS SDK for Java to interact with AWS APIs.
