4941.从公共到私有云：为什么会有如此变化？
[信息传输、软件和信息技术服务业] [2013-12-20]
One of the benefits of cloud computing is the array of hosting options available. There aresituations when a public cloud is the best choice to suit a company's needs. For someorganizations, a private cloud can offer the best solution. This article explains when becominga private cloud provider instead of a public cloud subscriber is a better choice. Learn how aprivate cloud differs from a virtual private cloud, and understand the benefits of making thetransition to a private cloud model.

4942.动物园管理员基本面、部署和应用
[信息传输、软件和信息技术服务业] [2013-12-20]
Apache ZooKeeper is a high-performance coordination server for distributed applications. It exposes common services -- such as naming and configuration management, synchronization, and group services -- in a simple interface, relieving the user from the need to program from scratch. It comes with off-the-shelf support for implementing consensus, group management, leader election, and presence protocols. In this article, we will explore the fundamentals of ZooKeeper, then walk through a guide to set up and deploy a ZooKeeper cluster in a simulated miniature distributed environment. We will conclude with examples of how ZooKeeper is used in popular projects.

4943.云端大数据
[信息传输、软件和信息技术服务业] [2013-12-20]
Big data is an inherent feature of the cloud and provides unprecedented opportunities to use both traditional, structured database information and business analytics with social networking, sensor network data, and far less structured multimedia. Big data applications require a data- centric compute architecture, and many solutions include cloud-based APIs to interface with advanced columnar searches, machine learning algorithms, and advanced analytics such as computer vision, video analytics, and visualization tools. This article examines the use of the R language and similar tools for big data analysis and methods to scale big data services in the cloud. It provides an in-depth look at digital photo management as a simple big data service that employs key elements of search, analytics, and machine learning applied to unstructured data.

4944.数据可视化,第1部分:可视化浏览与SVG和D3指标
[信息传输、软件和信息技术服务业] [2013-12-20]
In this two-article series, learn how to use Scalable Vector Graphics (SVG) with the open source D3 JavaScript library to create data visualizations. Shapes, colors, and layouts can be of great help in making business sense out of data volumes. An example scenario demonstrates the use of SVG and D3 for creating informative graphics out of browsing metrics for social media.

4945.Java多组织用户管理介绍
[信息传输、软件和信息技术服务业] [2013-12-20]
The IBM Multitenant JVM recently became available as part of the IBM Java 8 beta. Byrunning multiple applications within a single multitenant JVM, a cloud system can speedapplications' start times and reduce their memory footprint. This article introduces thetechnology behind multitenant cloud JVM and discusses the main costs and benefits.

4946.实时音译使用InfoSphereStreams自定义Java操作符和ICU4J
[信息传输、软件和信息技术服务业] [2013-12-20]
With the ever growing importance of Internet monitoring and sentiment analysis, there is an immediate need for identifying patterns (performing text analytics) in big data. However, one of the challenges during this exercise is that countries can have multiple languages that create a challenge for effectively running the text analytics, since rules are not available for all the languages. For example, in India, the official language of each state is different, and data is available in both English and local languages. This article describes how to bring about consistency during the transliteration process, and to use IBM? InfoSphere? Streams? to prepare linguistic data and apply text analytics or pattern recognition logic.

4947.学习R编程语言
[信息传输、软件和信息技术服务业] [2013-12-20]
R is a flexible programming language designed to facilitate exploratory data analysis, classical statistical tests, and high-level graphics. With its rich and ever-expanding library of packages, R is on the leading edge of development in statistics, data analytics, and data mining. R has proven itself a useful tool within the growing field of big data and has been integrated into several commercial packages, such as IBM SPSS and InfoSphere, as well as Mathematica. This article offers a statistician's perspective on the value of R.

4948.InfoSphereStreams同步数据和控制信号的时间序列工具包
[信息传输、软件和信息技术服务业] [2013-12-20]
InfoSphere Streams is the real-time component of the IBM big data platform. It provides the platform and toolkits for building real-time analytical solutions. The Time Series Toolkit included with Streams includes operators for preprocessing, analyzing, and modeling time series data in real time. Modeling operators in the toolkit use incoming time series data to build an internal model for forecasting or tracking. In real-world scenarios, the incoming data used for model building might become noisy and should be discarded from the model-building process. Also, once the incoming data is clean, the model might have to be retrained. This article provides a solution for this and describes how to synchronize and calibrate the process of model building and operator functions with the quality of incoming data using the control port feature.

4949.开发一个大数据应用程序来进行数据探索和发现
[信息传输、软件和信息技术服务业] [2013-12-19]
Exploring big data and traditional enterprise data is a common requirement of many organizations. In this article, we outline an approach and guidelines for indexing big data managed by a Hadoop-based platform for use with a data discovery solution. Specifically, we describe how data stored in IBM's InfoSphere? BigInsights? (a Hadoop-based platform) can be pushed to InfoSphere Data Explorer, a sophisticated tool that enables business users to explore and combine data from multiple enterprise and external data sources.
