Introduction to Microservice

Microservices Architecture

A variant of the service-oriented architecture (SOA) structural style - arranges an application as a collection of loosely coupled services. In a micro-services architecture, services are fine-grained and the protocols are lightweight.

Monolithic Architecture

• Built as a single unit
• Deployed as a single unit
• Duplicated on each server

From Monolith to Microservices

• Break your application/system in small units using Strangler Pattern

Micro-services Anti Patterns (What can go wrong)

• Risk of unnecessary complexity
• Changes may impact numerous services
• Complex security

Micro-services - Benefits

• Improved fault isolation
• Eliminate vendor or technology lock-in (because mostly open-source)
• Ease of understanding
• Smaller and faster deployments
• Scalability
