# 2.网络部署

本快速入门场景假设您是第一次安装 DFINITY Canister SDK 并在远程运行的 Internet Computer 网络上部署默认项目。

如果您只是在本地开发环境中部署项目，请参阅本地开发场景。

首先，让我们构建和部署一个简单的 Hello 应用程序，它只有一个函数——称为greet。 greet 函数接受一个文本参数并返回（命令行运行应用程序时在终端，浏览器访问应用程序时在网页）一个问候语。

Internet Computer容量的扩充通过向网络神经系统（NNS）提交议案。目前限制为系统Canister和已通过NNS审批的应用。在接下来的几周将通过NNS议案来增加应用子网以供开发社区使用。同时，我们鼓励您本地开发和部署。如果您尝试在没有可用应用子网的情况下部署，部署将会失败并且会导致部分单元(e8s)损失。
