AWS Lambda

I am using Twilio as my base application, which one should I prefer Twilio Functions or AWS Lambda function to host my functions which are called from Twilio plugins?

Which one is the best between Serverless framework and Claudia for AWS Lambda deployment? I just need the detailed difference between them to understand which is better.

Hey,

I want to stream incremental document updates (like a price change) to a ton of end users using SSE. What is the best tool for that? AWS Lambda's / Cloud Functions terminate too fast and Containers / Servers seem too expensive.

Users should authenticate and "subscribe" to a specific resource. I am planning to use a MongoDB Instance as a Database and Lambdas to write to it.

What's the difference between AWS Lambda and AWS Step Functions?

I intend to use a programming language which I'll use as AWS runtime and write a script that will comb through tons of files in a directory and its subdirectories and search for simple text regular expressions and process and write the matches in a file as output. I have heard that Perl is good for regex based search but I also want the performance to be good as it will have to go through tons of files for IO. In this post: https://filia-aleks.medium.com/aws-lambda-battle-2021-performance-comparison-for-all-languages-c1b441005fd1, I see that Rust works well as AWS Lambda runtime with very good performance. Which one should I choose as my AWS lambda runtime for this problem? Golang is also an option as it is fast as per the above link.

We are working on a transaction processing application and everything needs to happen in real-time. I have used AWS Lambda with Quarkus + Java, and struggled with cold start time however Lambda is still cost effective. so wanted to understand which one will be suitable as alternative to lambda services.
