What is the number of Lambda Function that I can run at a time

Question

Is there any limit to the number of Lambda function that can run at a time? Can someone help me with this? As at few places I read that there is a limit and some said there is no limits.

Thank you in advance for your help.

Answer 1

There is no limit with the number of Lambda functions you want to run. AWS Lambda was designed to run multiple instances of your function parallelly. Though, AWS Lambda comes with a default safety throttle for number of concurrent executions for each account per region. You can control the maximum concurrent executions for individual AWS Lambda functions and you can use to reserve the subset of your account concurrency limit for the use of critical functions, or limit traffic rates to downstream resources.
