In addition, recognize that with the evolution of third party expertise and economics, many areas that were once thought of as necessary to keep in house are now handled by others at lower costs.  This results in better outcomes so you can grow the strategic areas and focus great IT talent on the things that really matter – which leads to #2. Are you using valuable IT resources and highly skilled labor to manage tactical elements like communications infrastructure or telecom? If you’re dealing with the same old budget dilemmas and needing to reduce IT operating costs, get innovative.  Change the status quo.

MapReduce was designed by Google as a programming model for processing large data sets with a parallel, distributed algorithm on a cluster. The MapReduce Framework usually contains distributed servers and it runs various tasks in parallel to each other. As you can clearly see more this entire MapReduce Frameworks provides much more than just Map() and Reduce() procedures; it provides scalability and fault tolerance as well.
This Framework does the above Map () and Reduce () procedure in the parallel and independent to each other. In a future blog post of this 31 day series we will explore various components of this subject in Detail. It is equivalent to SELECT and GROUP BY of a relational database for a very large database.

In this article we will take a quick look at one of the four most important buzz words which goes around Big Data – MapReduce.
Though, MapReduce was originally Google proprietary technology, it has been quite a generalized term in the recent time. Procedure Map() performance filtering and sorting operation on data where as procedure Reduce() performs a summary operation of the data. There are various components which manages the communications between various nodes of the data and provides the high availability and fault tolerance. Programs written in MapReduce functional styles are automatically parallelized and executed on commodity machines.
A typical implementation of the MapReduce Framework processes many petabytes of data and thousands of the processing machines. Here is the basic explanation of the MapReduce Procedures which uses this massive commodity of the servers.
The master node collects the answer and once again aggregate that in the form of the answer to the original big problem which was assigned master node. All the Map() procedures can run parallel to each other and once each worker node had completed their task they can send it back to master code to compile it with a single answer. This model is based on modified concepts of the map and reduce functions commonly available in functional programming.


The MapReduce Framework takes care of the details of partitioning the data and executing the processes on distributed server on run time. This particular procedure can be very effective when it is implemented on a very large amount of data (Big Data). Along with 14+ years of hands on experience he holds a Masters of Science degree and a number of database certifications. Typically most of the staff is involved in day to day projects.  Consider restructuring highly skilled labor to your strategic areas of focus. The library where the procedure Map () and Reduce () belongs is written in many different languages. During this process if there is any disaster the framework provides high availability and other available modes take care of the responsibility of the failed node. The most popular free implementation of MapReduce is Apache Hadoop, which we will explore tomorrow. Once the worker node completes the process with this sub-problem it returns it back to master node.
