AWS Certified Developer Associate DVA-C02 Practice Question
An application is experiencing intermittent failures due to throttling when making requests to an AWS service. Which implementation would BEST enhance the application's resiliency by addressing these specific failures?
Increasing the timeout settings for the API requests
Migrating the application to run on larger EC2 instances
Implementing retries with exponential backoff and jitter
Creating additional replicas of the application's database
Implementing retries with exponential backoff and jitter is considered a best practice when dealing with intermittent failures, such as throttling by an AWS service. This approach gradually increases the wait time between retries, reducing the potential for recurring conflicts and mitigating the risk of overwhelming the service with repeated requests. Jitter further randomizes the wait times, helping to prevent synchronized retries from multiple sources, which could lead to additional throttling. The other options may provide benefits in different contexts but do not directly address the issue of intermittent failures due to throttling as effectively as exponential backoff with jitter.
