# Mastering Microservices Architecture: Breaking Down Monoliths for (Senior) Software Engineer Interviews

Prepare for Senior Software Engineer interviews with essential system design knowledge on decomposing monolithic applications into microservices. This episode provides practical strategies for extracting your first microservice from a monolith - a common technical interview topic that demonstrates architectural thinking and scalability expertise.

This episode provides valuable insights for senior engineers facing system design questions, while helping junior and mid-level developers develop the architectural thinking needed for career advancement. Understanding these microservices migration patterns demonstrates the strategic mindset that differentiates senior engineering candidates.

### Timestamps:
00:00 - Introduction to monolith decomposition
00:35 - Concrete example: extracting a customer wish list feature
01:31 - The code-first approach explained
02:13 - Benefits of code-first extraction
03:12 - Drawbacks of maintaining database coupling
04:00 - Importance of preliminary data planning
05:10 - The data-first approach explained
06:08 - Advantages of tackling data challenges upfront
06:44 - Complexities with data separation (integrity, transactions)
08:09 - Considering UI decomposition alongside backend changes
10:07 - Summary of code-first vs data-first strategies
10:56 - Additional challenges in microservices architecture

### In This Episode:
• Two primary strategies for extracting microservices: code-first vs. data-first approaches
• Real-world example using a customer wish list feature extraction
• How to manage database dependencies when transitioning to microservices
• Techniques for handling data integrity and transactions across distributed systems
• Parallel considerations for UI decomposition when breaking down monoliths

### Pro Tips for Seniors:
• Always develop a comprehensive plan for both code AND data migration before starting implementation
• Consider data relationships and integrity constraints early to avoid hitting dead ends after significant code investment
• Balance short-term organizational/deployment benefits against long-term technical coupling concerns
