Serverless

- No servers to manage

- Continuous scaling and balancing

- Pay only for used, not reserved time

- Less code to manage

Instead of a collection of functions calling each other, the best serverless applications are:

  • Thick client code handling all interaction logic
  • Heavy use of managed services (e.g., AppSync, @Auth0, @Algolia, @Cloudinary)
  • Small glue functions.

- JoeEmison (@joeemison)

The key benefit of serverless is not "no servers to manage". It's "almost no backend code".

Serverless

==

Serviceful Serverless

No server operations

Scales seamlessly

Codeless

No need to manage uptime

Assumes responsibility for providing a defined set of services

Serviceful Serverless

// Variable Expense

⚡️💡

 Think of managed services like the electricity that runs through your home.

// Less Code

Go for an application that any idiot can maintain - because sooner or later, any idiot probably is going to maintain it.

// Experimentation
