A lap around of Big Data with Microsoft HDInsight

Big Data synonyms with three V s :  Volume , Velocity & Variety. Even with traditional e-commerce system to modern social networks  all systems data conservation is dependent on this platform. Lets check a scenario of modern e-commerce analytic s after integration with Big Data.



  • Big Data platform typically works by storing data first into clusters , then process the data through MapReduce workflows which executes by Mapping the input data through independent chunks processed by appropriate algorithms, the output from Map phase then moves to Shuffle/Sorting phase & finally the output from Shuffle phase comes to Reduce phase as input.
  • Lets check a typical Big Data MapReduce workflow.




  • Microsoft’s BigData platform works exactly same way as a collaborative solution with Horton Works named as Microsoft HDInsight. Which typically simplifies the solution of running complex batch scripts. Lets cover a little insight of HDInsight/Hadoop ecosystem.


  • Microsoft’s Big Data platform unveils solutions from storing data into HDFS to query processing on Hive up to implementing Business Intelligence analytics on Excel Powerpivot, Powerpivot, SSAS & SSRS solutions.


  • Storing data into HDFS : Petabytes to Zetabytes of data to be stored in HDFS clusters by means of Name Node followed by Data Nodes, in Azure HDInsight each Data Node is integrated with a worker roles & compute cluster. Alternatively , you can leverage the solutions using Azure Blob Storage utilizing  Front End(attaches OAuth/Security layer for authentication), Partition layer: for mapping with Azure Queue, table & blob storages , Stream layer : 3 layer HA for scaled out data stream.


  • In order to programming on HDInsight , you can opt for Java, C#, F#, .NET, .js API, LINQ to Hive APIs which leverages to code on hadoop ecosystems including hadoop pig, hive, mahout, cascading, pegasus.

DOJO ToolKit with HTML 5 , CSS 3 & JavaScript for iPhone, iPad, Android & BlackBerry

DOJO Toolkit is an open source framework library well known for mobile web development close to native mobile applications for iPhone, iPad,BlackBerry, Android devices. It has close support for PhoneGap & renders controls with JavaScript , CSS 3 with HTML 5. It expects all features of Mobile Webkit browsers like Offline Cache, Browser manifest, local storage & isolation storage for mobile browsers etc.

  • So , It’s just another feather of JQTouch , Sencha Touch , JQuery Mobile but it has some of it’s unique features like Native Mobile application support like Google Maps with Location track, Enterprise Charts for Mobile, Mobile Gauge etc.
  • DOJO Toolkit initially is a project of Sun MicroSystems as open source DHTML based Ajax functionality with DOM support but later it’s divided into JavaScript, Ajax, HTML 5 , CSS 3 different features & provides native app support for mobile web 2.0
  • Though initial it’s support was based on Eclipse IDE of Java but I was keen to explore it’s features in my favourite IDE Visual Studio. So Download the toolkit from  http://dojotoolkit.org/download/   & extract it foundation files in three parts :

  •     Now , Add all the three folders of DOJO Toolkit “dijit, dojo, dojox” in Visual Studio Solution explorer & including “Show All Files” “include all the files in project”.
  •    Now start code by adding a new .aspx or .htm page with DOJO toolkit for Ajax, HTML 5, CSS 3, Google Ajax CDN, Mobile browser Webkit.
