Course Overview

This hands-on training focuses on building serverless applications using Kotlin on AWS Lambda. Designed for intermediate Kotlin developers, this course dives into writing, deploying, and managing AWS Lambda functions while using AWS CDK for infrastructure as code.

This training assumes prior Kotlin knowledge (completion of Kotlin Crash Course or Bite-Size Kotlin Training, or equivalent experience).

Learning Objectives

By the end of this training, participants will:

  • Learn how to write AWS Lambda functions in Kotlin and manage dependencies.
  • Set up AWS CDK with Kotlin to deploy Lambda functions and infrastructure.
  • Work with various Lambda triggers: API Gateway, EventBridge, SQS, SNS, DynamoDB Streams, and S3.
  • Implement output integrations, enabling Lambda to send data to S3, DynamoDB, SNS, SQS, and EventBridge.
  • Implement error handling and logging using Kotlin Logging.
  • Optimize AWS Lambda performance using AWS SnapStart and cold start reduction techniques.

Course Structure

Duration: 2 days
Format: Onsite or Remote

Day 1: Writing & Deploying Kotlin Functions on AWS Lambda

  • Introduction to AWS Lambda: Event-driven computing and best practices.
  • Setting up AWS CDK in Kotlin: Automating Lambda deployments.
  • Writing Kotlin-based Lambda functions: Dependencies, serialization, and testing.
  • Triggering Lambda functions:
    • API Gateway for HTTP requests.
    • EventBridge for event-driven architectures.
    • SQS & SNS for messaging and decoupling services.
    • DynamoDB Streams for real-time processing.
    • S3 Events for processing file uploads.

Day 2: Output Integrations, Logging & Optimization

  • Lambda Output Integrations:
    • Writing to S3 for event-driven file storage.
    • Saving data to DynamoDB for state persistence.
    • Publishing messages to SNS/SQS for further processing.
    • Sending events to EventBridge for event-driven workflows.
  • Error handling & logging: Implementing structured logging with Kotlin.
  • Performance optimization:
    • Reducing cold starts with AWS SnapStart.
    • Provisioned Concurrency and memory tuning.
  • Building a complete serverless application in Kotlin.
