1.

Financial Impact of Choosing
Microservices Architecture
• Minimal White Edition

2.

Agenda
• Problem
• Why Microservices Become Expensive
• Cost Structure
• Architecture Scheme
• Complexity Growth Diagram
• Case Comparison
• Summary

3.

Problem
Microservices often introduced too early:
• High infrastructure cost
• DevOps dependency
• Increased complexity
• Slower MVP delivery
• Delayed ROI

4.

Why Microservices Become Expensive
They require:
• Kubernetes / Orchestration
• CI/CD pipelines per service
• API Gateway / Service Mesh
• Monitoring & Logging systems
• High engineering overhead

5.

Cost Structure
Initial:
• Kubernetes setup
• CI/CD per service
• Decomposition
• Operational:
• • Monitoring, logging
• • Scaling multiple services
• Hidden:
• • Debugging distributed systems
• • Onboarding complexity

6.

Architecture Scheme: Monolith vs Microservices
Service 1
Monolith
(Single Unit)
API Gateway
Service 2
Service 3

7.

Complexity Growth: Monolith vs Microservices
Monolith (stable)
Microservices (increasing)

8.

Case Comparison
• Monolith: ~$300–700/month
• Microservices: $2,000–8,000+/month
• Monolith optimal early; Microservices optimal at scale.

9.

Summary
• Minimal White design applied
• Full architecture scheme added
• Complexity diagram included
• Microservices costly & complex
• Monolith cheaper for MVP
