Beginner’s Guide to Writing AWS Lambda Functions in Python

Noah Gift

AWS Lambda functions are the building blocks for creating sophisticated applications and services on AWS. In this online training you will use Python to develop Lambda functions that communicate with key AWS services, including: API Gateway, SQS, and Cloudwatch functions. You will also learn how a new cloud-based development environment, Cloud9, can streamline writing, debugging and deploying AWS Lambda functions.

One of the emerging cloud-native trends is serverless. This training covers real-world examples of how to run code without thinking about servers. Some of the benefits of programming with AWS Lambda in Python include: no servers to manage, continuous scaling, and subsecond metering. Several use cases include: data processing, stream processing, IoT backends, mobile, and web applications.

What you'll learn-and how you can apply it

  • Developing with Cloud9
  • Writing AWS lambda functions in Python
  • Implementing Cloud-native Data Engineering patterns, i.e. serverless
  • Architecting event driven architectures on the AWS platform using: SQS and Python Lambda

This training course is for you because...

  • You work with data and want to learn cloud-native data engineering patterns
  • You are new to the AWS Cloud and want to learn to write functions in Python that do not require servers
  • You are a Data Scientist who needs a simpler way to get Data Engineering results
  • You want to learn about serverless technology and how to accomplish it in Python
