3. Why Mercari Choose Microservices
4. 4 • To scale the service more than ever ◦ * (Code base is getting bigger and complex day by day...) ◦ Make it easy to try new feature / technology ◦ Make it easy to catch up the service logic / domain ◦ Cut down on-boarding cost ◦ Speed up the deployment cycle ▪ Reduce coordination with other teams Why Mercari choose Microservices
5. 5 • Fault Tolerance / Resilience ◦ As the service grows, some features become important components that should not be down (e.g. Timeline) ◦ Do not spread system failure to the whole ◦ Cut down operation cost Why Mercari choose Microservices
6. What are Microservices?
7. 7 • Simpler to deploy / Easy to understand • Reusability across business • Faster defect isolation • Minimize the risk of code changes What are Microservices?
8. 8 • Autonomous ◦ (Units that can be deployed independently) ◦ Isolate perspective: ▪ Data consistency and transaction boundaries ▪ Team, Technology, Cohesion, Security, ... What are Microservices?

16. Why Microservices Platform
17. 17 • Two reasons why Platform is required ◦ Team side ◦ System side Why Microservices Platform
18. 18 Why Platform is required: Team side

21. 21 Why Platform is required: System Side
22. 22 Monolithic App Data Access Layer Business Logic UI Database
23. 23 Monolithic App Data Access Layer Business Logic UI Database Microservices Apps Units that can be deployed independently
24. 24 Monolithic App Data Access Layer Business Logic UI Database Microservices Apps Units that can be deployed independently
25. 25 Monolithic App Data Access Layer Business Logic UI Database Microservices Apps Units that can be deployed independently
26. 26 Why Platform is required: System side • Bootstrap & Provision cost ◦ In case of Monolith, ▪ the infra can be used for every features (reusability) ◦ Unlike Monolith, ▪ need to build the infra for each micro service
27. Microservices Platform
28. 28 Microservices Platform • Centralized GKE Cluster ◦ 1 cluster per 1 region • Cloud resources for each microservice ◦ GCP Projects (Cloud SQL, Spanner, etc.) ◦ PagerDuty ◦ Datadog Dashboard

32. • Microservice Starter Kit ◦ It became easy for the developers to bootstrap own infrastructure by themselves ◦ Just by running 1 command locally, all resources needed for their microservice are created
