Questions.Answered.

Anything else? Ask us

What does a sleeping Function cost?

Nothing. A sleeping copy and its spares pay no CPU, memory or storage. The saved copies of its live and previous versions pay storage at $0.08 per GB a month. More

How long does a call wait for a sleeping Function?

It wakes on the call, as it was left. A copy asleep over 30 minutes is parked and takes longer to wake. More

What does an awake copy cost?

$0.03 per active vCPU-hour for the CPU it uses and $0.01 per GiB-hour of memory, only while awake. Calls cost $0.15 per million calls after your first 10,000 a month. More

When does a copy go to sleep?

Once it has been quiet longer than its usual gap between calls: a lone call sleeps within a quarter of a second, and no copy waits more than 5 seconds.

What can I run?

Any server in a Linux image that serves HTTP on the port it is given, in any language. A copy takes up to 16 vCPUs and 64 GiB of memory. More
