Getting started with Chalice to create AWS Lambdas in Python – Step by Step Tutorial Tech by Sunny Srinidhi - November 14, 2019November 14, 20190 If you’re into serverless stuff, you already know what is AWS Lambda. But if you don’t know, AWS Lambda is a serverless service provided by Amazon where you can create ‘functions’ and deploy them in AWS, which you can run without having any server instances (such as EC2).

Invoke an AWS Lambda Function from another Lambda Function Data Science Tech by Sunny Srinidhi - November 4, 2019November 4, 20190 I recently discovered that you can't invoke more than one Lambda function in AWS for an S3 event, with the same prefix and suffix (or just with the same suffix, which was the issue in my case). So I wanted a way to invoke one Lambda function from another Lambda function. If you're feeling kind of lost, check out the problem statement in my Github project. That could possibly add some context to the problem. If you don't want to go there, I'll try to explain it here again. The Problem and the Requirement In one of our projects, we have a Lambda function which is invoked whenever a text file is uploaded to a particular S3 bucket. The Lambda function takes
How to automatically trigger AWS Lambda functions using CloudWatch Tech by Sunny Srinidhi - November 2, 20190 If you have AWS Lambda functions which need to be triggered periodically, like CRON jobs, there are many ways to achieve this. But I recently discovered a very easy and AWS-way of doing this, which makes life a lot easier. So, there are a lot of ways you can trigger Lambda functions periodically. One of the most common ways I've see people doing this is adding an API Gateway to the Lambda function, and then calling that API periodically as a CRON job from one of the machines in the setup. I actually thought this is how you're supposed do to that. Okay, let me make this clear. I'm not a DevOps guy. I just learn these things as and when
