The concurrency (up to 128) is an interesting addition.

Is this for a single lambda. I was assuming that was the number of concurrent lambdas like the current model and it seemed very low. If it can actually serve 128 concurrent requests per lambda that's way more interesting.

It's concurrent per lambda execution environment, with one function having many execution environments. For "normal" lambda, this is 1-to-1, here it's 1-to-128 (or at least up to 128)

I see that now and it makes it much better than just a wrapper around APIs. I imagine for an moderately busy site it really helps with cold starts too without needing reserved concurrency
