Pros
- +Production-ready platform with Kubernetes and Kafka backing for enterprise-scale LLM applications
- +Event-driven architecture optimized for handling streaming AI workloads and real-time interactions
- +Comprehensive tooling including CLI, VS Code extension, and sample applications for rapid development
- +统一的分布式框架，将数据处理、训练、调优和服务集成在单一平台中，减少了技术栈复杂性和学习成本
- +平台无关设计，支持从本地开发到云端生产的无缝部署，兼容所有主流云提供商和Kubernetes环境
- +强大的生态系统，拥有41000+GitHub星数和活跃的社区，提供丰富的集成和扩展能力
Cons
- -Requires Java 11+ runtime dependency which adds complexity to deployment environments
- -Relatively new project with limited community adoption (421 GitHub stars)
- -Opinionated architecture that may not suit all AI application patterns beyond event-driven use cases
- -分布式系统的学习曲线较陡峭，需要理解分布式计算概念和Ray特有的编程模式
- -对于简单的单机任务可能存在过度工程化的问题，引入了不必要的复杂性
- -资源消耗较高，运行分布式集群需要相当的内存和计算资源投入
