AWS Lambda previewed November 13, 2014; GA April 9, 2015 — code with no servers to provision

Claim: AWS Lambda was previewed November 13, 2014, with general availability April 9, 2015. The service lets you run code with no servers to provision — billed by execution time and invocation count.

Confidence: Verified.

Why this matters for Candid: Lambda is the endpoint of the metering-granularity story (EC2 per-second billing introduced October 2, 2017 — replacing hourly increments in place since 2006). For a small site with a few authenticated form-submit endpoints, Lambda + RDS together can run for single dollars per month — a workload that in 2005 implied a dedicated server.
