Does Lambda run multiple containers when it says 1000 concurrent execution?

Question

当一个 lambda 的并发执行次数增加时，是否意味着 Lambda 服务在幕后为每个并发执行启动一个新容器，然后也会出现冷启动问题？

Answer 1

AWSwill reuse Lambda containers if possible. So not every request requires a new container to be provisioned. AWS does have to provision a separate Lambda container instance for each concurrent request. So if there are 1000 requests being processed simultaneously, there will need to be 1000 total Lambda container instances provisioned.
