This Deloitte white paper compares the total cost of ownership (TCO) between serverless and server-based cloud models. While EC2 can appear cheaper on infrastructure alone, serverless options like AWS Lambda and DynamoDB cut overall TCO by 38–57% due to savings in development and maintenance. Case studies show a transportation firm and a healthcare provider reducing costs significantly by adopting serverless. Benefits include faster provisioning (68% less time), reduced maintenance (45–80% lower costs), built-in scalability, and security. However, serverless is best suited for event-driven, scalable apps, while compute-heavy or long-running tasks may favor server-based setups.
