AWS Lambda continues to make significant performance improvements for all Lambda users, and remains committed to improving execution times for the existing on-demand scaling model. This new feature provides an option for builders with the most demanding, latency-sensitive workloads to execute their functions with predictable start-up times at I have a AWS Lambda function that creates an object from a s3 call in cold start. I then hold the object in the cache while the function is warm to keep load times down.

That makes it impossible to guarantee <1 second responses to events such as API Gateway, DynamoDB, CloudWatch, S3, etc. This analysis of AWS Lambda + private VPC container initialization times concluded: Jan 05, 2021 · This article describes AWS Lambda—the dynamically scaled and billed-per-execution compute service.
