Course Description

Learn to build, configure, and operate serverless applications with AWS Lambda. Starting from the execution model and handler contract, you progress through event-driven architectures, error handling with retries, DLQs and destinations, VPC connectivity, AWS SDK integrations, concurrency controls, performance tuning, and safe deployment strategies using versions, aliases, and traffic shifting. Every concept is reinforced with hands-on exercises in a live AWS Console.

Prerequisites

Introduction to Python Intermediate Python Introduction to AWS Boto in Python

Foundations of Lambda Function Development

This chapter introduces the core Lambda function model, including handlers, stateless execution, configuration, and environment management. You'll learn how Lambda executes code, how to configure functions for optimal performance, and how to write and test Lambda code locally.

Event Processing, Error Handling & Connectivity

This chapter covers how Lambda processes events, handles retries and failures, and connects to private resources. You'll learn the difference between synchronous and asynchronous invocations, how event source mappings batch records from queues and streams, and how to route outcomes with DLQs and destinations. You'll also see how VPC networking impacts connectivity and cold-start performance.

Integrations, Scaling & Performance Optimization

This chapter teaches how to integrate Lambda with other AWS services and tune functions for reliability, performance, and cost-efficiency. You'll learn how to use the AWS SDK safely with least-privilege permissions, how concurrency settings protect downstream systems, how to reduce cold-start and runtime latency, and how to deploy safely with versions, aliases, and traffic shifting.

This course is very interactive and useful. I loved each part of the course. However, I feel the video lectures are a bit fast and overwhelming as multiple concepts are explained within a very short period of time. In a whole, loved the interactive sessions and exercises a lot.
