Serverless and Faas Offer a Compelling Business Case
Serverless systems are having a significant impact on cloud costs. For example, running twelve (12) 200ms transactions using a traditional AWS EC2 t2.nano configuration would cost 2300 times more than running it in AWS Lambda. That is a very compelling reduction from $0.012 to $$0.000005.
In addition to these savings, having great elasticity by breaking an application monolith into independently deployed functions means a better ability to split teams to work on more things in parallel, and to deploy each feature separately.
Finally. some estimates out there show that moving to AWS Lambda gave an overall operational cost reduction of greater than 95% for a comparable amount of computing.
