Course Overview

This hands-on training equips your team to build serverless applications using Kotlin on AWS Lambda. Designed for intermediate Kotlin developers, this course covers 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).

What Your Team Will Be Able to Do

After completing this training, your developers will:

  • Build and deploy AWS Lambda functions in Kotlin with proper dependency management — ready for production workloads.
  • Automate infrastructure using AWS CDK with Kotlin to deploy Lambda functions and supporting resources as code.
  • Connect Lambda to any AWS event source — API Gateway, EventBridge, SQS, SNS, DynamoDB Streams, and S3 — to build event-driven architectures.
  • Integrate Lambda with downstream services — writing to S3, DynamoDB, SNS, SQS, and EventBridge for complete serverless workflows.
  • Implement structured error handling and logging so your team can debug and monitor Lambda functions in production.
  • Optimize cold start performance using AWS SnapStart and concurrency tuning to keep your serverless applications fast.

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.
