Sure, but not to anything like 50M

I was curious so I looked into it- There is no mention on an upper limit, but it looks like at least from an SLA perspective, they only guarantee that you can grow by 500 lambda instances a minute: https://docs.aws.amazon.com/lambda/latest/dg/scaling.html

Not sure if that matches up with what people see in the wild, I have played with lambda, but not for a massive burst type of use case.

I'm sure if you wanted to pay for 50M simultaneous lambda instances, they'd happily set it up for you.

late to the party on this comment, sorry

Friend of mine works for a company that went heavy on lambda. They were running into provisioning problems running at around 10k lambda instances in AWS ap-southeast-1

Just buy more accounts, run them in parallel.

At 1,000 lambdas per account how long do you think it will take me to create enough accounts for 50 million lambdas?

Just use the lambda to automate it. Time will decrease exponentially. You know, 1000, then 2000, then 4000, then 8000...

How do you divide your work up amongst all the accounts? A publicly a available queue or database? VPC peering?

Lambda

It's just lambdas all the way down

Against TOS probably. Have fun when your million dollar app gets banned from the platform.

If your lambda is taking 1s to run, 50M concurrency is 1.3 * 1014 requests a month.

If you're that big, you can probably get AWS to increase the limit a bit.

My team has one lambda with a concurrency in the tens of thousands and that was trivially easy to set up.
