For understanding more complex use cases of serverless technology read my second blog on AWS Lambda use cases – ‘10 Practical Examples of AWS Lambda’. Very simple to use from within AWS Lambda (it just takes 2 lines of code). Hopefully in the future, the API Gateway will honor the Content-Encoding header when proxying requests, and gzip (or otherwise compress) responses on its own. Virginia aws Lambda > Functions > Basic information Name face_recognition Role. The Node package “aws-lambda-multipart-parser” was found to be vulnerable to a ReDoS (Regular-Expression Denial of Service) attack vector. What this means in a nutshell is that it will take on all of the ‘busy work’ of hosting your deployed code, like memory allocation, container management, etc. js and AWS Lambda was peer reviewed by Camilo Reyes, Joan Yin, Yaphi Berhanu and Moritz Kröger. You are charged for every 100ms the code is executing. Conclusion. The Lambda itself is one piece of this architecture; it is a function that can be invoked and can return a result.
