Facebook lab rare exposure: App-
Facebook-IT bought more than 2000 films mobile phone testing information
Facebook has become a master of mobile social networking, WhatsApp, Messenger, Instagram, cell phone software, the number of users to hundreds of millions (WhatsApp users over 1 billion people). Foreign media news, in order to test software performance, Facebook acquired over more than 2000 Smartphone in the laboratory.
According to the United States Science and technology news site VentureBeat reported, Facebook recently disclosed the details in the data center. The company is located in United States, Oregon, Prineville data center, Facebook operates a laboratory, a total of more than 2000 more than smart phones will be to stress-test faces factory-mobile phone software, to ensure that they are able to cope with the massive mobile phone users access.
It is reported that about a year ago, for the new development of mobile phone software, Facebook engineers tend to use simple tests of the smart phone around.
But as we all know is that large number of smart phones on the market today, from the operating system, mobile phone screens, processors, not the same graphics chip, if only with a small amount of mobile phones tested, may not be able to ensure the quality of after the mobile phone software online.
Later, customized Facebook in the data center more than more than 60 cabinets each cabinet placed 32 smartphones.
A lot of smart phones, not only to ensure that the mobile phone software with maximum compatibility, ease pressure on the large external access to mobile phone software test.
According to Facebook engineer Antoine Reversat official blog revealed that for every change of APP,Facebook will conduct a thorough scan and test, Facebook will also make use of other computing devices running Smartphone, such as Apple Desktop Apple MAC Mini analog phones, Android phones such as is simulated by other servers.
Facebook, Instagram, Messenger, software, many users in the world, so that if a mobile device is not compatible, which means the world will have millions of, or even tens of millions of Facebook users were affected, so Facebook must ensure the completion of a thorough compatibility test.
According to reports, Amazon, Google and other cloud computing service providers, now also provides the pressure for mobile phone software and compatibility testing tool. But Facebook as big technology companies, have their own computing infrastructure, therefore decided to design their own smart-phone system of the Cabinet.
According to engineer disclosure, Facebook to Cabinet number of smartphones in the near future, increased 1 time.
It is worth mentioning that, in the mobile phone software development and testing, Facebook already has excellent physical infrastructure, but the overall APP development was disappointing.
To date, the mobile application developed by Facebook, was "phenomenal" success only two tools, Facebook and mobile chat Messenger is the main client, respectively, as the Star software WhatsApp and Instagram, are acquired from the outside.
Facebook develops a large number of mobile software, due to lack of access a user has to be closed, such as news aggregators read the Paper, news client, Notify,Facebook, burn after reading in the past also used to imitate Snapchat features several social networking tools, but all failed.
Facebook has also developed a Android desktop tool, and I installed my HTC smart phone. Result as a desktop APP, and HTC mobile phones, both lost.
Tencent technology notes that Facebook APP development strategies made the adjustment, no longer to launch features bits and pieces of small software, but through the chat robots, opening up and development of interfaces, such as through third-party force bigger and stronger WhatsApp, Instagram, Messenger, Facebook and a few stars of the software functions.
Facebook实验室罕见曝光：买了2000多部

Facebook已经成为移动互联网社交的霸主，WhatsApp、Messenger、Instagram等手机软件，用户数以亿计（WhatsApp用户超十亿人）。据外媒最新消息，为了对软件性能进行测试，Facebook的实验室中购置了2000多部智能手机。
据美国科技新闻网站VentureBeat报道，Facebook日前对外披露了数据中心的一个细节。在该公司位于美国俄勒冈州的Prineville数据中心，Facebook运营着一个实验室，共有2000多部智能手机将会对面临出厂的手机软件进行压力测试，确保他们能够应付海量手机用户的访问。
据悉，大约在一年前，对于新开发出的手机软件，Facebook的工程师往往只会用身边的智能手机进行简单的测试。
不过众所周知的是，如今市面上的智能手机数量众多，从操作系统、手机屏幕、处理器、图形芯片等各不相同，如果只是用少量手机进行测试，很可能无法保证手机软件上线之后的质量。
后来，Facebook在上述数据中心定制了60多个机柜，每一个机柜放置了32部智能手机。
大量的智能手机，不仅可以确保手机软件具有最大的兼容性，也方便对手机软件进行大规模外部访问的压力测试。
据Facebook的工程师Antoine Reversat在官方博客透露，对于每一个改动的APP，Facebook都会进行详细的扫描和测试，Facebook也会利用其他计算设备来模拟运行的智能手机，比如利用苹果台式机MAC Mini模拟苹果手机，利用其他服务器模拟安卓手机等。
Facebook、Instagram、Messenger等软件，全球用户众多，因此如果某一款移动设备出现不兼容，这意味着全球将会有几百万、甚至几千万的Facebook用户受到影响，因此Facebook必须确保完成彻底的兼容性测试。
据报道，亚马逊、谷歌等云计算服务商，目前也提供了手机软件压力和兼容测试工具。不过Facebook作为大型科技公司，拥有自己的计算基础设施，因此决定单独设计自己的智能手机机柜系统。
据工程师披露，Facebook未来还要把智能手机的机柜数量，增加一倍。
值得一提的是，在手机软件开发和测试上，Facebook已经具备了优秀的硬件基础设施，但是其APP开发整体令人失望。
迄今为止，Facebook自行开发的手机软件中，获得“现象级”成功的只有两款工具，分别是主力客户端Facebook以及移动聊天工具Messenger，作为明星软件的WhatsApp和Instagram，均从外部收购获得。
Facebook开发的大量手机软件，由于无法获得用户已经被关闭，比如新闻聚合阅读工具Paper、新闻客户端Notify，Facebook过去还曾经模仿Snapchat的阅后即焚特色，推出几款社交工具，但是全部失败。
Facebook还曾经开发一款安卓的桌面工具，并且预装到了HTC的智能手机中。结果这一桌面APP和HTC的手机，双双败北。
腾讯科技注意到，Facebook对APP开发的战略做出了调整，不再推出功能零碎的小软件，而是通过聊天机器人、开放开发接口等方式，借助第三方力量做大做强WhatsApp、Instagram、Messenger、Facebook等少数明星软件的功能。
