Easier packaging and deployment

The packaging and deployment of your application in a FaaS environment is really simple compared to deploying your application to a container or even an entire server. With FaaS, all you will be doing is creating your artifact (JAR (JVM)/ZIP (Node.js or Python)) and then uploading them directly to the FaaS offerings. You don't need any additional deployment or configuration management tools to deploy your applications to a FaaS environment. Some of the cloud providers do provide access to write the application directly in the console itself. 

As there is no need to have additional configuration or deployment tools, system administration is significantly reduced.
