A company's application, which uses an Amazon API Gateway REST API to invoke an AWS Lambda function, is experiencing long cold-start times due to the Lambda function's initialization process of loading a large dataset from a DynamoDB table equipped with DynamoDB Accelerator (DAX). Customers have reported intermittent long response times. The application's request volume varies significantly throughout the day, peaking at 10 times the normal rate during midday and dropping to 10% of its usual volume by the end of the day. To address these latency issues, a DevOps engineer is tasked with finding a solution to consistently reduce the Lambda function's latency at all times of the day. Which solution should the engineer implement?
