Let’s see at how to set AWS Lambda function to execute Python script from the internet call.
We used to deploy our software on physical or virtual servers with pre-installed environments. It is easy to copy your Python script to that machine and run it via command line. But what if you need this operation be done once at month within a specific environment. Do we need to prepare whole computing instance for this small operation? Another example. We need our code executed each time it triggered, but we cannot predict how often it will happen.
Thanks to AWS we have a simple solution. There is a service called AWS Lambda. Based on information provided on official page, AWS Lambda lets you run code without provisioning or managing servers — all with zero administration. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app. Let’s see at how to set AWS Lambda function to execute Python script from the internet call.
Firstly, go to the Functions page on the AWS Lambda section and click on ‘Create function’ button:
There are many code samples and presets in Blueprints section. Moreover, we could use a big ready-to-deploy app library in App Repository section. But we do not need them at the moment, let’s start with simple ‘hello world’ example. Enter name for our function and choose runtime environment:
In this article, I am going to explain how to create an AWS Lambda function and then call this function from another Lambda function within the same region. This is a useful scenario in which we may need to execute a second lambda function based on the outcome of some previous logic
Modernizing web application development and deployment. Let's describe a phase 1 AWS architecture including Github, API Gateway, and AWS Lamba python functions. This represents an initial tutorial exposing developers to the AWS cloud adoption learning curve. Outline:
Serverless Express enables you to easily host Express.js APIs on AWS Lambda and AWS HTTP API. Here is how to get started and deliver a Serverless Express.js based API with a custom domain, free SSL certificate and much more!
Python Lambda Functions. Python lambda functions are an invaluable feature. One of the benefits of using Python is that it facilitates a relatively compact code structure compared to other programming languages. This means getting so much more done with fewer lines of code. One such tool is the lambda function. These allow us to create anonymous functions in python.
