5. Monolith vs Microservices Application Monolith Microservices
6. Monolith vs Microservices Deployment Monolith Microservices
7. Characteristic of Microservices 1. Componentization via Services 2. Organized around Business Capabilities 3. Products not Projects 4. Smart endpoints and dumb pipes 5. Decentralized Governance 6. Decentralized Data Management 7. Infrastructure Automation 8. Design for failure 9. Evolutionary Design https://martinfowler.com/articles/microservices.html
8. Componentization via Services Library Service Product Library Shipping Library Product Service Shipping Service
9. Organized around Business Capabilities Merchant Product Shipping
10. Decentralized Data Management MySQL Mongo Elasticsearch
11. Continuous Delivery Infrastructure Automation Unit Test Integration Test Deploy to Staging Application Acceptance Test Deploy to Production Post Deploy Test
12. Design for failure • Monitoring • Circuit Breaker • Chaos Monkey
13. How Big is Microservices? • Single Responsibility • Small enough to fit in in my head • X people per Service
14. Monolith • Simplicity • Consistency • Easy to Refactor • Partial Deployment • Availability • Multiple Platform • Easy to Scale Microservices
15. Event-Driven Architecture

22. API-Driven • Highly-coupled • Centralized business logic • Consistent • Increase response time • Sync Event-Driven • Decoupling • Decentralized business logic • Eventual consistent • Reduce load on producer • Replicated data • Async
23. The Challenges of Event-Driven Microservices • Idempoten • Asynchronous • Message Schema • Versioning • Tracing • Message Order • Consumer Complexity • Message Broker
24. Hands-On using Java
25. Tools Required for This Workshop • Java Development Kit version 1.8 or Higher • Apache Maven version 3 • Apache Kafka version 2.3 • MongoDB version 4 • Elasticsearch version 7.2
26. MonoPay • MonoPay is whitelabel system for e-Wallet • Merchant can use MonoPay to support e-Wallet feature in their system • MonoPay support member management, topup management, purchase management and point management • MonoPay use monolith architecture
