10 - Microservices and Service Integration

Overview

Microservices architecture has become a dominant paradigm for building scalable, maintainable, and loosely coupled systems. This topic explores the key aspects of transitioning from monolithic systems to microservices, defining service boundaries, managing service communication, handling distributed transactions, and strategies for code sharing. It also delves into migration strategies, integration patterns, and the trade-offs inherent in microservices design.

Fundamentals of Monoliths and Microservices

Monolithic Architecture

A monolithic system is a single, unified codebase where all components are tightly coupled.

Pros:

• Faster initial development and deployment.
• Easier debugging due to a single codebase.
• Simpler to manage in small teams or early-stage projects.

Cons:

• Slower testing and deployment cycles as the codebase grows.
• A single failure can bring down the entire system.
• Limited flexibility in adopting new technologies.
• Difficult to scale specific components independently.

Microservices Architecture

Microservices divide an application into smaller, independent services, each responsible for a specific business capability.

Pros:
