<p>Layotto(/leɪˈɒtəʊ/) 是一款使用 Golang 开发的应用运行时, 旨在帮助开发人员快速构建云原生应用，帮助应用和基础设施解耦。它为应用提供了各种分布式能力，比如状态管理，配置管理，事件发布订阅等能力，以简化应用的开发。</p>
<p>Layotto 以开源的 <a href="https://github.com/mosn/mosn" target="_blank" rel="noopener noreferrer">MOSN</a> 为底座，在提供分布式能力以外，提供了 Service Mesh 对于流量的管控能力。</p>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id="诞生背景">诞生背景<a class="hash-link" aria-label="诞生背景的直接链接" title="诞生背景的直接链接" href="/layotto/#诞生背景"></a></h2>
<p>Layotto 希望可以把 <a href="https://www.infoq.com/articles/multi-runtime-microservice-architecture/" target="_blank" rel="noopener noreferrer">Multi-Runtime</a> 跟 Service
Mesh 两者的能力结合起来，无论你是使用 MOSN 还是 Envoy 或者其他产品作为 Service Mesh 的数据面，都可以在不增加新的 sidecar 的前提下，使用 Layotto 为这些数据面追加 Runtime 的能力。</p>
<p>例如，通过为 MOSN 添加 Runtime 能力，一个 Layotto 进程可以<a href="/layotto/docs/start/istio/start">既作为 istio 的数据面</a> 又提供各种 Runtime API（例如 Configuration API,Pub/Sub API 等）</p>
<p>此外，随着探索实践，我们发现 sidecar 能做的事情远不止于此。 通过引入<a href="https://en.wikipedia.org/wiki/WebAssembly" target="_blank" rel="noopener noreferrer">WebAssembly</a> ,我们正在尝试将 Layotto 做成 FaaS (Function as a service) 的运行时容器 。</p>
<p>如果您对诞生背景感兴趣，可以看下<a href="https://mosn.io/layotto/#/zh/blog/mosn-subproject-layotto-opening-a-new-chapter-in-service-grid-application-runtime/index" target="_blank" rel="noopener noreferrer">这篇演讲</a>

<p>如下图架构图所示，Layotto 以开源 MOSN 作为底座，在提供了网络层管理能力的同时提供了分布式能力，业务可以通过轻量级的 SDK 直 接与 Layotto 进行交互，而无需关注后端的具体的基础设施。</p>
<p>Layotto 提供了多种语言版本的 SDK，SDK 通过 gRPC 与 Layotto 进行交互。</p>
<p>如果您想把应用部署到不同的云平台（例如将阿里云上的应用部署到 AWS），您只需要在 Layotto 提供的 <a href="https://github.com/mosn/layotto/blob/main/configs/runtime_config.json" target="_blank" rel="noopener noreferrer">配置文件</a>
里修改配置、指定自己想用的基础设施类型，不需要修改应用的代码就能让应用拥有"跨云部署"能力，大大提高了程序的可移植性。</p>
