Crash Course: Exiting the Monolith
Mentor — Vitalii Hryhoryshyn, Team Lead at Ven Commerce Ltd, 19+ years in IT
This course is a practical guide for developers and tech leads who want to move from monolith to microservices and serverless through a gradual and controlled migration.
Based on real e-commerce cases, you will learn to diagnose monolith problems, correctly choose the first points for isolation and build new services on AWS Lambda.
Mentor — Vitalii Hryhoryshyn, Team Lead at Ven Commerce Ltd, 19+ years in IT, of which 13+ in highload systems and e-commerce.
You will go through the path in detail from the first technical solution to a systemic approach: from isolating one endpoint through Strangler Fig to building a strategy for gradual decomposition of the monolith. You will receive specific tools and patterns that you can apply next week.
- After the course you will:
- understand how to actually start migration from a monolith, rather than postpone it
- be able to isolate the first service without risk for production
- gain practical experience with AWS Lambda, API Gateway, S3
- learn to build a strategy for gradual system decomposition
- be able to align architectural changes with business goals
Audience
- Developers who want to grow towards architecture
- Techleads
- Everyone who adds features to a monolith every day and realizes that this cannot go on

Program
Webinar 1. Monolith diagnostics and real cases
- Symptoms and metrics: when a monolith becomes a problem
- Architecture analysis: how to find a place that prevents scaling
- How to choose the first candidate for selection: criteria and pitfalls
- How to deal with a manager who doesn't want to cut into microservices: arguments, metrics, persuasion strategies
- Architectural allocation patterns: Strangler Fig, Anti-corruption Layer
- Real-life e-commerce cases: step-by-step allocation of an endpoint from a legacy, working with shared data and transactions
Between webinars: independent practice
- To complete the practical task, you need an AWS account (Free Tier enough)
- Video demo from the mentor: implementing Strangler Fig via Lambda + API Gateway + S3
- Task: configure API Gateway and deploy Lambda function for image processing
- Questions and difficulties are collected in the chat and sorted out at the beginning of the second webinar
Webinar 2. From Lambda to migration strategy
- Homework analysis: typical mistakes and how to avoid them
- How serverless fits into the overall monolith migration strategy
- Communication between services: synchronous vs asynchronous
- Queues and events: when to use SQS or EventBridge
- Monitoring and observability for a new service
- What's next: a plan for gradual decomposition of the monolith
