FaaS
(Function as a Service)
Running small pieces of code on demand in the cloud without managing the computers underneath
What's it for?
Runs small pieces of code only when needed so organisations do not have to keep a full server running all the time.
For example…
When a form is submitted, a function resizes the uploaded image and stores it automatically
A new image upload triggers a FaaS function that creates smaller thumbnail versions only when files arrive, rather than running a server continuously.
Think of it like…
Hiring a handyperson only for the five-minute job, not paying for a full-time caretaker
