+Kubernetes 做出贡献，涉及的领域包括控制器、API 服务器以及 kubectl。
+
+<!--
+**Janet**: Certainly! I'm Janet, a Staff Software Engineer at Google, and I've been deeply involved
+with the Kubernetes project since its early days, even before the 1.0 launch in 2015.  It's been an
+amazing journey!
+
+My current role within the Kubernetes community is one of the chairs and tech leads of SIG Apps. My
+journey with SIG Apps started organically. I started with building the Deployment API and adding
+rolling update functionalities. I naturally gravitated towards SIG Apps and became increasingly
+involved. Over time, I took on more responsibilities, culminating in my current leadership roles.
+-->
+**Janet**：当然可以！我是 Janet，在 Google 担任资深软件工程师，
+并且从 Kubernetes 项目早期（甚至在 2015 年 1.0 版本发布之前）就深度参与其中。
+这是一段非常精彩的旅程！
+
+我在 Kubernetes 社区中的当前角色是 SIG Apps 的主席之一和技术负责人之一。

+
+<!--
+At this point in time, the main factors driving the development of our controllers are the
+challenges coming from running various AI-related workloads. It’s worth giving credit here to two
+working groups we’ve sponsored over the past years:
+-->
+在当前阶段，推动我们控制器开发的主要因素是运行各种 AI 相关工作负载所带来的挑战。
+在此值得一提的是，过去几年我们支持的两个工作组：
+
+<!--
+1. [The Batch Working Group](https://github.com/kubernetes/community/tree/master/wg-batch), which is
+   looking at running HPC, AI/ML, and data analytics jobs on top of Kubernetes.
+2. [The Serving Working Group](https://github.com/kubernetes/community/tree/master/wg-serving), which
+   is focusing on hardware-accelerated AI/ML inference.
+-->
+1. [Batch 工作组](https://github.com/kubernetes/community/tree/master/wg-batch)，
+   该工作组致力于在 Kubernetes 上运行 HPC、AI/ML 和数据分析作业。
+2. [Serving 工作组](https://github.com/kubernetes/community/tree/master/wg-serving)，

+## Best practices and challenges
+
+**Sandipan: SIG Apps plays a crucial role in developing application management best practices for
+Kubernetes. Can you share some of these best practices and how they help improve application
+lifecycle management?**
+-->
+## 最佳实践与挑战
+
+**Sandipan**：SIG Apps 在为 Kubernetes 开发应用程序管理最佳实践方面发挥着关键作用。
+你能分享一些这些最佳实践吗？以及它们如何帮助改进应用程序生命周期管理？
+
+<!--
+1. Implementing [health checks and readiness probes](/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/)
+ensures that your applications are healthy and ready to serve traffic, leading to improved
+reliability and uptime. The above, combined with comprehensive logging, monitoring, and tracing
+solutions, will provide insights into your application's behavior, enabling you to identify and
+resolve issues quickly.
+-->
+1. 实施[健康检查和就绪探针](/zh-cn/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/)
+   确保你的应用程序处于健康状态并准备好处理流量，从而提高可靠性和正常运行时间。
+   结合全面的日志记录、监控和跟踪解决方案，上述措施将为您提供应用程序行为的洞察，
+   使你能够快速识别并解决问题。
+
+<!--
+2. [Auto-scale your application](/docs/concepts/workloads/autoscaling/) based
+   on resource utilization or custom metrics, optimizing resource usage and ensuring your
+   application can handle varying loads.
+-->
+2. 根据资源利用率或自定义指标[自动扩缩你的应用](/zh-cn/docs/concepts/workloads/autoscaling/)，
+   优化资源使用并确保您的应用程序能够处理不同的负载。
+
+<!--
+3. Use Deployment for stateless applications, StatefulSet for stateful applications, Job
+   and CronJob for batch workloads, and DaemonSet for running a daemon on each node. Use
+   Operators and CRDs to extend the Kubernetes API to automate the deployment, management, and
+   lifecycle of complex applications, making them easier to operate and reducing manual
+   intervention.
+-->
+3. 对于无状态应用程序使用 Deployment，对于有状态应用程序使用 StatefulSet，
+   对于批处理工作负载使用 Job 和 CronJob，在每个节点上运行守护进程时使用
+   DaemonSet。使用 Operator 和 CRD 扩展 Kubernetes API 以自动化复杂应用程序的部署、
+   管理和生命周期，使其更易于操作并减少手动干预。
+
+<!--
+**Sandipan: What are some of the common challenges SIG Apps faces, and how do you address them?**
+
+The biggest challenge we’re facing all the time is the need to reject a lot of features, ideas, and
+improvements. This requires a lot of discipline and patience to be able to explain the reasons
+behind those decisions.
+-->
+**Sandipan**：SIG Apps 面临的一些常见挑战是什么？你们是如何解决这些问题的？
+
+我们一直面临的最大挑战是需要拒绝许多功能、想法和改进。这需要大量的纪律性和耐心，
+以便能够解释做出这些决定背后的原因。
+
+<!--
+**Sandipan: How has the evolution of Kubernetes influenced the work of SIG Apps? Are there any
+recent changes or upcoming features in Kubernetes that you find particularly relevant or beneficial
+for SIG Apps?**
+
+The main benefit for both us and the whole community around SIG Apps is the ability to extend
+kubernetes with [Custom Resource Definitions](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)
+and the fact that users can build their own custom controllers leveraging the built-in ones to
+achieve whatever sophisticated use cases they might have and we, as the core maintainers, haven’t
+considered or weren’t able to efficiently resolve inside Kubernetes.
+-->
+**Sandipan**：Kubernetes 的演进如何影响了 SIG Apps 的工作？
+Kubernetes 最近是否有任何变化或即将推出的功能，你认为对
+SIG Apps 特别相关或有益？
+
+对我们以及围绕 SIG Apps 的整个社区而言，
+最大的好处是能够通过[自定义资源定义（Custom Resource Definitions）](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)扩展
+Kubernetes。用户可以利用内置控制器构建自己的自定义控制器，
+以实现他们可能面对的各种复杂用例，而我们作为核心维护者，
+可能没有考虑过这些用例，或者无法在 Kubernetes 内部高效解决。
+
+<!--
+## Contributing to SIG Apps
+
+**Sandipan: What opportunities are available for new contributors who want to get involved with SIG
+Apps, and what advice would you give them?**
+-->
+## 贡献于 SIG Apps
+
+**Sandipan**：对于想要参与 SIG Apps 的新贡献者，有哪些机会？
+你会给他们什么建议？
+
+<!--
+We get the question, "What good first issue might you recommend we start with?" a lot :-) But
+unfortunately, there’s no easy answer to it. We always tell everyone that the best option to start
+contributing to core controllers is to find one you are willing to spend some time with. Read
+through the code, then try running unit tests and integration tests focusing on that
+controller. Once you grasp the general idea, try breaking it and the tests again to verify your
+breakage. Once you start feeling confident you understand that particular controller, you may want
+to search through open issues affecting that controller and either provide suggestions, explaining
+the problem users have, or maybe attempt your first fix.
+-->
+我们经常被问道：“你们建议我们从哪个好的初始问题开始？” :-)
+但遗憾的是，这个问题没有简单的答案。我们总是告诉大家，
+为核心控制器做贡献的最佳方式是找到一个你愿意花时间研究的控制器。
+阅读代码，然后尝试运行针对该控制器的单元测试和集成测试。一旦你掌握了大致的概念，
+试着破坏它并再次运行测试以验证你的改动。当你开始有信心理解了这个特定的控制器后，
+你可以搜索影响该控制器的待处理问题，提供一些建议，解释用户遇到的问题，
+或者尝试提交你的第一个修复。
+
+<!--
+Like we said, there are no shortcuts on that road; you need to spend the time with the codebase to
+understand all the edge cases we’ve slowly built up to get to the point where we are. Once you’re
+successful with one controller, you’ll need to repeat that same process with others all over again.
+
+**Sandipan: How does SIG Apps gather feedback from the community, and how is this feedback
+integrated into your work?**
+-->
+正如我们所说，在这条道路上没有捷径可走；你需要花时间研究代码库，
+以理解我们逐步积累的所有边缘情况，从而达到我们现在的位置。
+一旦你在一个控制器上取得了成功，你就需要在其他控制器上重复同样的过程。
+
+**Sandipan**：SIG Apps 如何从社区收集反馈，以及这些反馈是如何整合到你们的工作中的？
+
+<!--
+We always encourage everyone to show up and present their problems and solutions during our
+bi-weekly [meetings](https://github.com/kubernetes/community/tree/master/sig-apps#meetings). As long
+as you’re solving an interesting problem on top of Kubernetes and you can provide valuable feedback
+about any of the core controllers, we’re always happy to hear from everyone.
+-->
+我们总是鼓励每个人参加我们的双周[会议](https://github.com/kubernetes/community/tree/master/sig-apps#meetings)，
+并在会上提出他们的问题和解决方案。只要你是在 Kubernetes 上解决一个有趣的问题，
+并且能够对任何核心控制器提供有价值的反馈，我们都非常乐意听取每个人的意见。
+
+<!--
+## Looking ahead
+
+**Sandipan: Looking ahead, what are the key focus areas or upcoming trends in application management
+within Kubernetes that SIG Apps is excited about? How is the SIG adapting to these trends?**
+
+Definitely the current AI hype is the major driving factor; as mentioned above, we have two working
+groups, each covering a different aspect of it.
+-->
+## 展望未来
+
+**Sandipan**：展望未来，Kubernetes 中应用程序管理的关键关注领域或即将到来的趋势有哪些是
+SIG Apps 感到兴奋的？SIG 是如何适应这些趋势的？
+
+当前的 AI 热潮无疑是主要的驱动因素；如上所述，我们有两个工作组，
+每个工作组都涵盖了它的一个不同方面。
+
+<!--
+**Sandipan: What are some of your favorite things about this SIG?**
+
+Without a doubt, the people that participate in our meetings and on
+[Slack](https://kubernetes.slack.com/messages/sig-apps), who tirelessly help triage issues, pull
+requests and invest a lot of their time (very frequently their private time) into making kubernetes
+great!
+-->
+**Sandipan**：关于这个 SIG，你们最喜欢的事情有哪些？
+
+毫无疑问，参与我们会议和
+[Slack](https://kubernetes.slack.com/messages/sig-apps) 频道的人们是最让我们感到欣慰的。
+他们不知疲倦地帮助处理问题、拉取请求，并投入大量的时间（很多时候是他们的私人时间）来让
+Kubernetes 变得更好！
