Today, two of the most popular technologies are Big Data and Cloud Computing that are fundamentally different. On one hand, Big Data is all about dealing with huge data amount. On the other hand, cloud computing is all about handling enterprise infrastructure. Both of these technologies have simplified many business operations together. One of the good examples of the merger of these technologies is Amazon “Elastic Map Reduce” that leverages the power of Big Data Processing and Cloud Computing both. 

The combination of both technologies yields beneficial outcomes for organizations. However, both technologies are in their evolution phase but the combination of both the technologies may leverage cost-effective and scalable business solutions. 

So, can we assume that cloud computing and big data is the perfect and leveraging combination? Well, this article is all about the effect of big data and cloud computing technologies on business operations.

In this post I will share some tips I learned after using the Apache Hadoop environment for some years, and  doing many many workshops and courses. The information here considers Apache Hadoop around version 2.9, but it could definably be extended to other similar versions.

These are considerations for when building or using a Hadoop cluster. Some are considerations over the Cloudera distribution. Anyway, hope it helps! 

• Don't use Hadoop for millions of small files. It overloads the namenode and makes it slower. It is not difficult to overload the namenode. Always check capability vs number of files. Files on Hadoop usually…

Imagine there are two girls standing in front of you – The first girl is cute, beautiful, interesting and has the smile that any guy would die for. And the other girl is average-looking, quiet, not-so-impressive… no different from the ones that you usually see in the restaurant cash counter. Which girl will you call out for a date? If you’re like me, you will choose the attractive girl. You see, life is full of options and making the right choice is what matters the most.

If you’re a Java developer, then you probably have more choices to make – like the switch from Java to Hadoop.

Big data and Hadoop are the two most popular buzzwords in the industry. Chances are that you have come across these two terms on the Java payscale forums or seen your senior colleagues making the switch to get…

Considered as the fourth industrial revolution, Blockchain Technology is making news everywhere. This technology that was created for supporting cryptocurrencies has found ways to enter different industries like finance, commerce, judiciary & so on.

In this article, I will discuss how Blockchain technology was built, how it works & also some of its features. It is a must read for those who have been hearing about the Blockchain technology from here & there and feel curious to know more.

Let us begin!

Background of Blockchain Technology

Invented by Satoshi Nakamoto in the years 2008, Blockchain Technology served as the very effectual public transaction ledger of Bitcoin (cryptocurrency). But now it is going to have a great impact on institutional functions, national…

The prior achievement of the internet has largely been reliant on technology and how it has evolved over the years- getting faster and more secure as enterprises continue to grow with analytics and innovation. Big Data is one of these major breakthroughs, serving huge functions at modern organizations. Concepts like data driven machine learning and the ability to store huge amounts of information to gain context from has been hugely beneficial towards the strategic aspects of running international businesses. Organizations have been making huge changes to the structure of their own infrastructure and workplace processes, to accommodate the latest data science systems into their functioning. But, as the industry expands, traditional educational foundations may not cut it and a dynamic approach toward professional development is recommended. To that end, certification programs are ideal for professionals in the industry who seek to hone their skillsets in particular ways depending on…

Being one of the most interesting topics to have a conversation on nowadays, Data Science is developing every minute and we got to keep pace with the changes taking place in the huge and complex world of Data Science.

An issue that has been worrying a lot of organizations today is the shortage of individuals with data science skills. As per a report by IBM, by the year 2020, the demand for data science professionals is going to expand by 30 percent, however, the chances of this demand being sully met are quite bleak.

If you visit LinkedIn, you will come across nearly 6000 job postings for data scientists. And this high need for talented data scientists is not only being experienced by the United States but almost all the nations around the globe are facing the same challenge.

In this article, we are going to discuss the trends along with predictions that are likely to drive the popular field of data science in the years to come.

The SAP engineers as well as the software professionals at Sapphire Now have offlate been discussing the possible restrictions and likelihood for SAP S/4HANA for acting as a robust platform primarily for the purpose of managing the enterprise based strategies for Internet of Things as well as Big Data.

The general notion in the mindset of the people is that Internet of Things (IoT) is capable of sending out a tidal wave of enormous quantities of data in any enterprise. It is has been projected that billions of controllers and sensors, who are all capable of connecting to some other machine for the instruction and analysis, are eagerly waiting for the creation of trillions of data events along with transactions. The SAP managers and engineers has gone ahead and shared their views through a series of conversations when they were probed on how an organization could simply reconcile huge data quantities with in-memory built-for-speed…

Apache HADOOP is a framework used to develop data processing applications which are executed in a distributed computing environment.

In this tutorial we will learn,

• Components of Hadoop
• Features Of 'Hadoop'
• Network Topology In Hadoop

Similar to data residing in a local file system of personal computer system, in Hadoop, data resides in a distributed file system which is called as a Hadoop Distributed File system.

Processing model is based on 'Data Locality' concept wherein computational logic is sent to cluster nodes(server) containing data. This computational logic is nothing but a compiled version of a program written in a high level language such as Java. Such a program, processes data stored…

Quite often, while working with Hbase, I used to feel how cool it would be to have a database that can replicate my data to datacenters across the world consistently. So that I can take the pleasure of global availability and geographic locality. And also which will save my data even in case of some catastrophe or natural disaster. Which supports general-purpose transactions, and provides a SQL-based query language. And which has features of an SQL database as well. But it was only untill recently I found out that it is not an imagination anymore.

I was sitting with a senior+friend of mine at a Cafe…

When you learn about Big Data you will sooner or later come across this odd sounding word: Hadoop - but what exactly is it?

Put simply, Hadoop can be thought of as a set of open source programs and procedures (meaning essentially they are free for anyone to use or modify, with a few exceptions) which anyone can use as the "backbone" of their big data operations.

I'll try to keep things simple as I know a lot of people reading this aren't software engineers, so I hope I don't over-simplify anything - think of this as a brief guide for someone who wants to know a bit more about the nuts and bolts that make big data analysis possible.…

Hadoop – the software framework which provides the necessary tools to carry out Big Data analysis – is widely used in industry and commerce for many Big Data related tasks.

It is open source, essentially meaning that it is free for anyone to use for any purpose, and can be modified for any use. While designed to be user-friendly, in its “raw” state it still needs considerable specialist knowledge to set up and run.

Because of this a large number of commercial versions have come onto the market in recent years, as vendors have created their own versions designed to be more easily used, or supplied alongside consultancy services to get you crunching through your data in no time.

These days, this is often…

Batch data processing is an efficient way of processing high volumes of data is where a group of transactions is collected over a period of time. Data is collected, entered, processed and then the batch results are produced (Hadoop is focused on batch data processing). Batch processing requires separate programs for input, process and output. An example is payroll and billing systems.

Big data analytical ecosystem architecture is in early stages of development. Unlike traditional data warehouse / business intelligence (DW/BI) architecture which is designed for structured, internal data, big data systems work with raw unstructured and semi-structured data as well as internal and external data sources. Additionally, organizations may need both batch and (near) real-time data processing capabilities from big data systems.

Data is an advantage for industries as it benefits them make up-to-date choices. Strange! Data is being produced at an extraordinary rate and establishments are hording it like there’s not any tomorrow, generating enormous data groups we call big data. But is big data serving these businesses or is it just obscuring the decision-making procedure? We will find out.

Big data has numerous applications and, collective with analytics, is cast-off to find responses to glitches in a variation of businesses. For organisations, it can benefit them comprehend customer behavior and get most out of business procedures, all of which, in concept, should help administrators make sound choices to drive business development. But like so numerous things that complete good in concept, it’s not precisely working out for numerous organisations. In a worldwide review of over 300 C-level initiative administrators by Chartered Global Management Accountant (CGMA), which was complemented…

Price discrimination and downward demand spiral are widely used analytical concepts/practices in the Airlines and Hospitality industries respectively, long before the term Big Data Analytics was even coined. Incidentally, these concepts have been taught in global elite b-schools for decades. So, how come Analytics, which has been there in practice for decades experience a meteoric rise suddenly? To answer this question, we need to get the Big Picture. Given below are key factors that led to huge buzz around analytics today.

The advent of sharing economy has brought a sea change in the way urban populace commute locally. The Ubers, Lyfts and many other local players have made taxi riding convenient, affordable and safe. These rides have emerged as a strong alternative to the public transport clocking millions of rides per month in some cities. The emergence of hyper-local delivery models to optimize the supply chain has also led to a large number of daily trips by these vehicles.

These developments have mandated the installations of either standalone or smartphone app-based GPS devices to keep track of and better regulate these rides and a fleet of taxis. These GPS systems spew a ton of data generating up to GBs of…
