Serverless computing is an system architecture design that focus emphasis is abstracting the entirety of the infrastructure to let developers focus solely on code.
Per say , with AWS Lamba + API Gateway + S3 developers can create Web Application that usually required EC2 Servers and web framework like Spring , Laravel etc...
Apps hosted on AWS with EC2 requires strong knowledge in system architecture and system design . They also are quiet complex to scale , monitor and manage.
Serverless abstract all this and lets you focus only on code.
AWS Lambda is self healing meaning when a function crash , only that function crash not the entire server , API Gateway is managed by AWS it won't crash ( or very unlikely ) S3 , as i'm concerned , as never let me down.
Meaning I could author an entire application similar to Hacker News without any "Server" logically speaking, technically speaking there is always a server just like NoSQL doesn't mean "NO SQL" but "Not Only SQL" and is not buzzword :)
