Hat OpenShift Service Mesh Operator 支持部署多个版本的 ServiceMeshControlPlane，所以 Service Mesh 没有为产品的次版本维护单独的文档。 除非在一个特定主题或特定功能中明确指定了特定的版本，当前的文档集适用于所有当前 支持的 Service Mesh 版本。 如需有关 Red Hat OpenShift Service Mesh 台生命周期政策。 1.1.1. Red Hat OpenShift Service Mesh 简介 Red Hat OpenShift Service Mesh 通过在应用程序中创建集中控制点来解决微服务架构中的各种问题。它 在现有分布式应用上添加一个透明层，而无需对应用代码进行任何更改。 微服务架构将企业应用的工作分成模块化服务，从而简化扩展和维护。但是，随着微服务架构上构建的企 业应用的规模和复杂性不断 恢复、指标和监控的服务网络提供了便捷的方法。服务网格还提供更复杂的操作功能，其中包括 A/B 测 试、canary 发行版本、访问控制以及端到端验证。 1.1.2. 核心功能 Red Hat OpenShift Service Mesh 在服务网络间提供了实现关键功能的统一方式： 流量管理 - 控制服务间的流量和 API 调用，提高调用的可靠性，并使网络在条件不好的情况保持 稳定。 服务标识和安全性 -
