Serverless, code more

Hands-off (server) service

Don't need to maintain OS patch updates, containers and Kubernetes
Built-in resilience and fault tolerance

Automated elastic scale:

Scale up and down automatically to meet demand.
Scalability can sometimes (0.25% in AWS Lambda) result in “cold starts”, or to “warm up” your code when it hasn’t been called in a while.

Consumption-based billing

Pay for computing when you use, not for storage

Architecting differently

App has to be broken down into discrete services and interact with each other.
Good for the new application, not for legacy one.
