Function as a service (FaaS) is a way to keep the focus on business delivery. Basically, we don't know how our code will run, infrastructure. Here we now how aws lambda works and how to run PHP into AWS Lambda
3. Function as a Service - FaaS/Serverless
Software developers can leverage this to deploy an individual
“function”, action, or piece of business logic. They are expected to
start within milliseconds and process individual requests and then
the process ends.
Principles of FaaS
- Complete abstraction of servers away from the developer
- Billing based on consumption and executions, not server
instance sizes
- Services that are event-driven and instantaneously scalable
