There is no disputing the financial model behind AWS Lambda is revolutionary. I know of a visitor NDA signing service that charges $5 per visitor. The backend runs entirely on AWS API Gateway and Lamdba and their cost per visitor transaction to AWS is $0.25. Think about how powerful this is! Now you can develop an app in your spare time and bring it to market for practically nothing. Once developed, your fix infrastructure costs are zero. That said, there are financial benefits on premise too. Short lived processes that need 1 CPU and 512Mb memory are ideal candidates for oversubscription. If you had a server where CPU utilization never peaked beyond 60% and 15Gb memory was free then you could fit 20 Lambda functions in this 'slack capacity' without resource contention. Driving up utilization when the cost of the server is sunk is effectively capacity for free. |
