Serverless Computing Service - Free AWS Lambda - AWS
Compute service that runs your code in response to events and automatically manages the compute resources.
Module 2: Build a Serverless Function
In this module, you will be writing a small piece of code, in Python, JavaScript, or Java, to be used in a later module to add interactivity to your web page. You will use AWS Lambda, a compute service that lets you create serverless functions, eliminating the need for you to manage software and hardware. Instead, applications are broken up into individual functions that can be invoked and scaled individually.
These serverless functions are triggered based on a specific event you will define in the code. … Best of all, you do not have to worry about managing any servers.
OK, so I think AWS Lambda is about creating small functions and attaching them with events.
lambda_function.py from the tutorial
# import the JSON utility package since we will be working with a JSON object
import json
# define the handler function that the Lambda service will use as an entry point
def lambda_handler(event, context):
# extract values from the event object we got from the Lambda service
name = event['firstName'] +' '+ event['lastName']
# return a properly formatted JSON object
return {
'statusCode': 200,
'body': json.dumps('Hello from Lambda, ' + name)
}then,
Module 3: Link a Serverless Function to a Web App
configure a path with the function created to serve API (In this module, it's REST API).
AWS Lambda seems to be helpful when creating a very simple API, such as an experimental one or API with tiny responsiblity, but I'm not sure how it works in real life.
