介绍 (Introduction)

In the 90s and at the beginning of the 21 century, Linux and Windows were decidedly working at cross purposes

在90年代和21世纪初，Linux和Windows绝对是跨领域的

However, starting on 2009, Microsoft started to contribute with code in the Linux Kernel. On 2013, Azure supported Virtual Machines in Ubuntu and later came the support to .NET in Linux, Visual Studio for Linux, PowerShell in Linux, support to monitor Linux server to monitor in SCOM (System Center Operation Manager) and now, the support for SQL Server that is on the previous version when this article was published and it is planned to be released this year (2017). Microsoft is a Platinum member of the Linux Foundation now.

但是，从2009年开始，Microsoft开始在Linux内核中贡献代码。 2013年，Azure在Ubuntu中支持虚拟机，后来又支持Linux中的.NET，Linux中的Visual Studio，Linux中的PowerShell，监视Linux服务器以在SCOM中监视（ 系统中心操作管理器 ），以及现在对Linux的支持。发布本文时的早期版本上SQL Server，计划于今年（2017）发布。 微软现在是Linux基金会的白金会员。

Now, the Microsoft CEO, Satya Nadella, says that Microsoft Loves Linux. But why?

现在，微软首席执行官Satya Nadella表示微软喜欢Linux。 但为什么？

Because there are thousands of Server administrators who use Linux and they are potential customers to use the Microsoft Cloud (Azure). According to Microsoft, around 33% of the VMs in Azure are Linux machines. Two years ago, the number was 20% and each day these numbers are growing.

因为有数千名使用Linux的服务器管理员，他们是使用Microsoft Cloud（Azure）的潜在客户。 微软表示，Azure中大约33％的VM是Linux计算机。 两年前，这个数字是20％，并且每天这些数字都在增长。

Note, that Microsoft has more than $2 billion in revenue per year in Azure and it is planned to earn 20 billion on 2018.

请注意，微软每年在Azure中的收入超过20亿美元，并计划在2018年实现200亿美元的收入。

If we talk about laptops and desktop computers, Linux has 21.7% to the marketing (and Windows 8, 8.1, 10, etc. 52%) of the usage share. If we talk about Internet Servers, Linux has 35.0% of the usage share (and Windows Server 32.2% according to W3Techs).

如果我们谈论便携式计算机和台式计算机，则Linux占市场份额的21.7％（Windows 8、8.1、10等52％）。 如果我们谈论Internet服务器，则Linux拥有35.0％的使用份额（根据W3Techs，Windows Server为32.2％）。

So the simple fact is that Linux includes millions of potential users that are now using Azure and other Microsoft technologies and increasing Microsoft revenues.

因此，简单的事实是，Linux包括数百万潜在用户，这些用户现在正在使用Azure和其他Microsoft技术并增加了Microsoft的收入。

In addition, other databases like MySQL, Oracle, DB2 are multi-platform, which is sometimes a crucial feature for many companies.

此外，MySQL，Oracle，DB2等其他数据库也是多平台的，对于许多公司而言，有时这是至关重要的功能。

SQL Server vNext是倾向于多平台的新SQL Server。 SQL Server现在正迁移到Microsoft世界之外，并成为最危险的Oracle敌人（当前是世界上最受欢迎的数据库）。

We expect to have more supported tools and functionality in the future. Today, there are several tools that can only be installed on Windows, but this may change in the near future.

我们希望将来有更多受支持的工具和功能。 今天，有几种工具只能安装在Windows上，但是在不久的将来可能会改变。
