# What Causes AWS Lambda Cold Starts & 7 Ways to Solve Them

### Complete the form below to join this webinar

Cold starts can significantly affect your application's user experience. They occur when the AWS Lambda service needs to spin up a new execution environment before handling a new request. Initializing a new execution environment adds to the overall latency of the Lambda invocation. AWS has continuously improved the cold start performance of Lambda, including the introduction of proactive initialization. But cold starts are still a problem in many applications.

Join Yan Cui, AWS Serverless Hero, to learn more about common mistakes leading to cold-start performance issues and guide you through practical steps to enhance performance. This webinar is for developers interested in improving the efficiency and responsiveness of their serverless applications. 

This webinar will teach you how to tackle cold starts by reducing their frequency and duration, including how to measure cold start durations correctly.
