Kotlin 移至了采纳阶段，如今我们的许多团队报告称，Kotlin 不仅成为了他们在 JVM 语言上的 默认选择，而且已经几乎完全取代了 Java，成为他们编写软件的主要语言。与此同时，microservice envy 似 乎正在减弱，我们注意到人们开始使用诸如 Spring Modulith 等框架，探索具有更大可部署单元的架构。我们 已经知道有许多出色的 Kotlin 原生框架，并且在 Modulith 评估 尽管我们是微服务（microservices）的早期倡导者，并看到该模式在无数系统上取得了成功，但我们也看到微 服务被误用和滥用，这通常是 microservice-envy（microservice envy）导致的。与其从头开始构建一个由单 独部署的进程组成的新系统，我们通常建议从一个精心设计的单体应用开始，并且仅当应用程序达到一定规模 时，才将其分解为可单独
