Serverless
computing is an event-driven application design and deployment paradigm in
which computing resources are provided as scalable cloud services. In
traditional application deployments, the server's computing resources represent
fixed and recurring costs, regardless of the amount of computing work that is
actually being performed by the server. In a serverless computing deployment,
the cloud customer only pays for service usage; there is never any cost
associated with idle, down-time.
Serverless computing does not eliminate servers, but
instead seeks to emphasize the idea that computing resource considerations can
be moved into the background during the design process. The term is often
associated with the NoOps movement and the concept may also be referred to as
"function as a service (Faas)" or "runtime as a service
(RaaS)."
One example of public cloud serverless computing is the
AWS Lambda service. Developers can drop in code, create backend applications,
create event handling routines and process data - all without worrying about
servers, virtual machines (VMs), or the underlying compute resources needed to
sustain an enormous volume of events because the actual hardware and
infrastructure involved are all maintained by the provider. AWS Lambda can also
interact with many other Amazon services, allowing developers to quickly create
and manage complex enterprise-class applications with almost no consideration
of the underlying servers.
