2. 2 About me @tjun SRE at Merpay Engineering Manager
3. 3 • Intro: Merpay and microservices • Developing Merpay microservices • Operating Merpay microservices • About Merpay SRE • Summary
4. Introduction to Merpay and Microservices
5. 5 Mobile payment service that can be used through the marketplace app Mercari. Released 2019-02. Providing - iD(NFC) payment - Code payment - Payment inside mercari - Deferred pay（あと払い） - Coupon - Bank charge
6. 6 • Merpay with microservice architecture ◦ Almost all merpay services are on the microservices platform ◦ Over 40 microservices (Go, Node.js) ◦ Examples: ▪ Internal services: payment-service, bank-service ▪ Service with Web: coupon-service and coupon-web-service ▪ Service with API: nfc-service and nfc-api-service
7. 7 Merpay handles payment transactions • A lot of batches (ref: iD決済を支える技術 by @hiraku) • Connect with many external partners ◦ bank, merchants, iD payment provider, payment gateway... • Restricted ownership for developers
