Understanding the impact of mobile app markets on software practice

最近的市场研究预测，到2016年底，全球移动的应用经济预计将达到1430亿美元。但是，与传统软件不同，移动的设备上的软件应用程序（或移动的应用程序）的分发机制非常不同-它们通过应用程序市场发布（例如，Google Play或Apple的App store）。这样的应用市场改变了软件开发者与用户互动的方式、软件发布的方式以及用户消费软件的方式。有三种类型的开发者属于应用市场生态系统：（a）构建和发布应用的开发者（例如，发布愤怒的小鸟的Rovio娱乐公司），（B）构建跨许多不同应用程序使用的软件库的开发人员（例如，Facebook SDK库），以及（c）构建和维护应用商店的开发人员（例如，Google/BlackBerry）。

Recent market studies predict that the global mobile app economy is expected to be worth $143 billion by end of 2016. However, unlike traditional software, the distribution mechanism for software applications on mobile devices (or mobile apps) is very different - they are released through app markets (e.g., Google Play, or Apple’s App store). Such app markets have changed the way software developers interact with users, the way software is released, and the way users consume the software. There are three types of developers that belong to the app market ecosystem: (a) the developer that builds and releases the apps (eg., Rovio Entertainment that released Angry Birds), (b) the developers that build software libraries that are used across many different apps (eg., the Facebook SDK library), and (c) the developers that build and maintain the app store (eg., Google/BlackBerry).
