Which invocation frequency makes Provisioned Concurrency cost‑effective for sporadic Lambda traffic?
Goal Determine the break‑even invocation rate for a low‑traffic Lambda function where Provisioned Concurrency (PC) becomes cheaper than on‑demand execution, taking into account current pricing, cold‑start penalties, and ARM‑based Graviton2 cost reductions. Constraints Invocations < 100 per day, highly irregular. Function memory 512 MB, Java 11 runtime. Co
