使用云实例
本节说明如何在
DigitalOcean
（
http://digitalocean.com
）云实例上设置成熟的
Python
基础设施。还有许多其他云提供商，其中包括领先的提供商
Amazon Web Services
（
http://aws.amazon.com
）（
AWS
）。但是，
DigitalOcean
以其简单性和较小云实例
相对较低的费率而闻名，它被称为
Droplet
。最小的
Droplet
通常足以用于探查研究
和开发，每月仅需花费
5
美元，即每小时只需花费
0.007
美元。举个例子，因为按
小时收费，一个人便可以轻松地将一个
Droplet
启动两个小时，然后将其销毁，仅
收取
0.014
美元。

本部分的目的是在
DigitalOcean
上设置一个
Droplet
，该
Droplet
安装了
Python 3.8
，
加上通常需要的软件包（例如
NumPy
和
pandas
）以及受密码保护和使用安全套接字
层（

具套件，
Jupyter Lab
提供了一些可通过常规浏览器使用的工具：
Jupyter Notebook
在基于浏览器的交互式开发环境中，它是最流行的其中之一（如果不是唯一最
流行的）。其中包含多种不同语言的内核，例如
Python
，
R
和
Julia
。
