• 可以自動驗證 API 合約，或許可使用顧客合約與使用方驅動合約（例如 Pact-JVM）
等技術。
• 可以高效地mock（例如WireMock）、 stub（例如stubby4j）或虛擬化（例如
Hoverfly）透過 API 來公開的相關服務。
• 更容易透過內部資源端點（例如 Codahale Metrics 或 Spring Boot Actuator）讀取數
據與監視資料。
最近 API 的流行程度已經呈指數級成長了，但是要輕鬆地實現持續交付，你要在有充分
的理由時才使用它們，在使用它們時，也要製作優良的架構。

試著提供 app 生命週期管理、組態、log 與交易管理等功能。隨著 Amazon Web Services
（AWS）、 Google Cloud Platform（GCP）與 Microsoft Azure 提供的雲端計算，平台即
服務（PaaS）產品（例如 Heroku、Google App Engine 與 Cloud Foundry），以及容器即
服務（CaaS）產品（例如 Kubernetes、Mesos 與 Docker Swarm）等服務的出現，現代
的 Java 開發者有更多選項了。架構的最佳做法也隨著底層的部署結構與平台的變化而有
