I\'m trying to find the maximum number of virtual processor cores available in AWS Lambda. The official documentation implies that it scales with the amount of configured me
You're asking the wrong question I think (or want to use Lambda for something where it's not built for). One Lambda function has only one or two cores available, however, the power in Lambda is that you can run hundreds of them at the same time. The default limit of the amount of active Lambda functions is 100, but this is just a limit to safeguard the infrastructure (and your wallet). You can ask for more.
So your account can have 100 Lambda functions running at the same time, which you could see as 100 cores (however it's not). If you request a limit increase, this could also be 1000 or 10,000 or 100,000.
Analogy: instead of having 1 100-core computer, you have 100 1-core computers.
