Developers using Lambda have a range of options for performance-tuning their functions. Understanding how to get the most from Lambda can improve your application throughput, reduce latency, and lower overall cost. In this tech talk, learn about some of the newest features that can optimize Lambda performance, including improved VPC networking and Provisioned Concurrency. We cover common misconceptions about cold starts, and the different impact of cold starts between sync, async, and streaming invocations. See how making good architectural decisions can help improve performance. Learn about why memory allocation is so important and how to profile your Lambda functions to find the optimal configuration. We’ll also talk about best practices for Lambda to help you get the most from your serverless applications.
