!!! Overview
[{$pagename}] ([FaaS] [Cloud functions]) is a [Cloud Services Model] where some amount of [server-side] logic is still written by the application developer but unlike traditional architectures is run in [stateless] compute [containers] that are [event-triggered], [ephemeral] (may only last for one invocation), and fully managed by a [Cloud Service Provider].
Building an [application] following this model is one way of achieving a "[serverless]" [architecture], and is typically used when building [microservices] based [applications].
Some implementations are:
* [picos]
* [AWS Lambda]
* [Webtask]
* [OpenWhisk] ([Apache] and [IBM])
* [Azure Functions]
* [Google Cloud Functions]
* [Cloudflare] [Workers]
* Many Others.
[{$pagename}] all use the same basic [Serverless] [event-triggered] structure consisting of:
* Trigger ([Event-triggered]) - A class of [event] emitted by event sources.
* Actions - Encapsulate the actual code to be executed
* Rules - provide association between a [Event-triggered] and an action.
!! [{$pagename}] and [Synchronous Operation] and [Asynchronous Operation]
* [Synchronous Operation] - ([Webhook]) [gRPC]???
* [Asynchronous Operation] - Primarily used for background operations uses [Publish-Subscribe] and the outcome is not required in real time. Typically used with a call-back.
