Hadoop Distributions: Comparison and Top 5 Trends

Kirill Grigorchuk

Ever wondered how Hadoop distros differ from each other? In a recent article for NetworkWorld, I overview how Hadoop became what it is today and explore the differences between the standard edition vs. Hortonworks, Cloudera, and MapR. I also provided insights into 5 major trends that are shaping their evolution—in terms of features, ecosystem, enterprise adoption, etc.

Read the article to learn about:

– The top 5 trends currently affecting the evolution of Hadoop distributions
– Why enterprises need Hadoop distros and how they differ
– How YARN has solved the issues present in Hadoop 1.0
– What will become of Hadoop in the foreseeable future

5 Facts You Probably Don’t Know About AWS

Kirill Grigorchuk

Amazon Web Services

1. AWS is affordable

Over the last couple of years, the cost of AWS has been plummeting. You need to understand that the price you pay for a cloud consists of multiple components. Users often try to multiply the cost of instances by the number of hours used. Unfortunately, doing this does not give you an idea of how much the service costs. To understand, how much you will be paying for your cloud, you should calculate not only the price of cloud computing itself but also the cost of internet traffic and storage. You should also determine, if you need a certain guaranteed bandwidth and an amount of memory larger than that installed on standard instances, etc. In total, throughout the seven years from the moment the cloud service had been launched, its price has fallen by over 2500%.

2. You can pay ten times less for the same AWS resources

If used correctly, AWS can provide considerable computing resources at a much lower cost than it may seem at first glance. For example, if you buy a Reserved Instance as a base node (or a base set of nodes) and use the right type of architecture that will enable your application to process tasks using Spot Instances, the cost of cloud ownership can be reduced drastically. At the same time, 71% of users still use the Instance On-demand model.

SmartTV: Television Is in Again

Kirill Grigorchuk

Many of you can have already heard or even seen on your TVs such a word combination, as “Smart TV”. Let’s analyze briefly what it means and what it will bring to us in the future.

Let’s start with the definition. SmartTV is a TV set or a receiver with a built-in Internet access module. This technology is a computer system integrated into a TV, and more often, it allows installing additional software. Although the SmartTV technology is just beginning to develop, such large TV suppliers as Samsung, Sony, LG, and others actively promote it to the market. Unfortunately, nothing has been done yet to work out any standards for building SmartTV software, which makes the situation messed up a bit. That’s why most devices currently work on Linux, UNIX, Android OSs, and their modifications.

Play vs. Grails: Which One is Better Than Ruby on Rails?

Kirill Grigorchuk

While searching for new technologies, we came across Play—a framework for building Web apps with Java and Scala. One of our R&D experts shared his thoughts and ideas regarding this technology. In general, he had positive feelings about Play. It’s really simple compared to Spring or Struts. However, Play has a strong competitor, Grails. In this post, I made a small comparison of Play vs. Grails and added some thoughts on benchmarking both vs. Ruby on Rails.
