AWS price cuts: is serverless gaining momentum?

A serverless platform is an abstracted cloud computing service that executes a user’s code without the user needing to provision the underlying server or operating environment. The physical server, resources and operating environment used to execute the user’s code are managed by the cloud provider and are not accessible to the user (hence "serverless"). In July, Amazon Web Services (AWS) announced a price cut to its serverless platform, Lambda, but only for high levels of consumption.

Why would AWS make this price cut? In a serverless computing service, developers upload code via a graphical user interface or application programming interface (API). The user defines a trigger that executes this code, such as an API call sent from an application, a timer or an event on another cloud service. When triggered, the serverless platform assigns resources to the code, executes it and returns any result.
