Serverless

• Serverless

  • Serverless is a new paradigm in which the developers don’t have to manage servers anymore…
  • They just deploy code
  • They just deploy… functions !

• Serverless does not mean there are no servers…

  • it means you just don’t manage / provision / see them
• Initially… Serverless == FaaS (Function as a Service)
• Serverless was pioneered by AWS Lambda but now also includes anything that’s managed: “databases, messaging, storage, etc.”
