Cold starts in AWS Lambda occur when a function is invoked after being inactive or during rapid scaling, leading to additional latency as a new execution environment is initialized. Although typically brief, these cold starts can impact performance, making it crucial to develop strategies to manage their effects. Understanding the initialization steps involved—such as resource provisioning and execution environment creation—allows developers to optimize workloads effectively. By implementing the right tools and techniques, it is possible to minimize the impact of cold starts and ensure a low-latency user experience.
Cold starts in AWS Lambda refer to the additional latency introduced when initializing a new execution environment for a function invoked after a period of inactivity.
They occur because serverless platforms are designed for cost-efficiency, provision resources only when needed, which results in new execution environments requiring initialization.
