Thanks for this video! What VS Code extension are you using that gives you the time complexity of your functions?

Thanks for sharing this great video. It’s good to know how much it costs. I heard a lot about the cold start, which is one of the major cons to scare away some people choosing lambda. However, it only takes “typically under 1% of invocation”. If an api is so cold that it’s not accessed every 5 or 10 min, why do we care about the cold start for a fraction of second? And if the access is more frequently, it will keep warm and no more problem. So is this warm ping or provision concurrency really necessary? Did I miss some major points?

Hi, thank you for those incredible explanations! I have a question though, I'm wondering if you knew how to configure an Amplify app running with NextJs SSR in order to avoid cold start too at the page loading? There is no configuration file in an Amplify project for the main lambda that serves the html, so do you have a solution for this use case? Thanks a lot

Are they any notable advantages of provision concurrency over pinging with compared to the cost?.. As in why we should consider it when it cost that much?. :)

Thanks for solution! How to implement lambda ping solution using aws cdk node.js? I have tried multiple solution but didn't find proper solution.

We solved it in a much simpler and cost effective way: When the user browses to the application i.e. the login page, the login page on load just pings the lambda to get it warmed up. By the time user fills login form, the lambda is warmed up. Much cheaper and simpler solution.

That is why I never liked the provisioned capacity feature. It could be useful only if its cost was comparable to the ping overhead. But it is at least 100 times higher. P.S. Because the ping handler does nothing, AWS charges only 0.1 second for the ping call, so the pinging will be 10 times even more cheap than in your calculation.

When you say one 100 lambda do you mean a hundred functions?

In this case as you can see from the code shown, it's only one function with 100 instances.
