PaaS (Platform-as-a-service) is a kind of cloud service, the service provider not only provides on-demand hardware and operating system services, but also provides the application platform and solution stack. For developers, PAAs greatly reduces the cost and pain of it deployments, providing resources for applications to scale more easily as needed. JVMs, application servers, and deployment packages (for example, war and ear) provide natural isolation for Java applications, allowing different developers to deploy applications in the same infrastructure, so JAV ...

Grid computing can organize a large number of decentralized computers into a "virtual http://www.aliyun.com/zixun/aggregation/13840.html" > supercomputer, which should be one of the major technical tools for large data and high performance computing challenges. This article mainly introduces the method of writing grid applications on the IBM Platform Symphony platform in the Java language. Background The grid computing is distributed computing (Distribut ...).

Hadoop, a distributed computing open source framework for the Apache open source organization, has been used on many of the largest web sites, such as Amazon, Facebook and Yahoo. For me, a recent point of use is log analysis of service integration platforms. The service integration platform will have a large amount of logs, which is in line with the applicable scenarios for distributed computing (log analysis and indexing are two major application scenarios). Today we come to actually build Hadoop version 2.2.0, the actual combat environment for the current mainstream server operating system C ...

Hadoop is a distributed computing open source framework for the Apache open source organization that has been applied to many large web sites, such as Amazon, Facebook and Yahoo. For me, one of the most recent usage points is the log analysis of the service integration platform. The service integration platform's log volume will be very large, and this also coincides with the application of distributed computing scenarios (log analysis and indexing is the two major scenarios). Today we will actually build a Hadoop 2.2.0 version, the actual combat environment for the current mainstream server operating system C ...

Too much protocol and customization has led to the current disunity field of Internet, where each agency develops products that are printed with their own labels. Thankfully, there are also many institutions that are contributing to the development of the ecosystem as a whole. Prior to the Eclipse Foundation's foray into the internet of things, did the Machine-to-machine standard have been Dongfeng? In this article, we describe the Eclipse Foundation's 4 new projects to establish the Internet standards agreement and tools, and have been responded to by many names such as IBM, Sierra Wireless, Eurotech and Axeda. According to the recent ...

Companies such as IBM®, Google, VMWare and Amazon have started offering cloud computing products and strategies. This article explains how to build a MapReduce framework using Apache Hadoop to build a Hadoop cluster and how to create a sample MapReduce application that runs on Hadoop. Also discusses how to set time/disk-consuming ...

When it comes to application programming, Android is like an elephant in a room for a designer. Many designers would prefer this to be iOS, where all anyone cares about is the iphone, the ipad and the app Store. And no one can ignore Android, which now has the biggest market share in smartphones and has been widely used in a variety of products ranging from tablets to e-readers. In short, Google's Android platform is rapidly growing everywhere, brand manufacturers are hard to not notice. Let's face it together. Android ...
