What is Big Data?

Big Data has become the buzzword over the past few years. Do you know why this word has become a buzzword? Why big data becomes more popular? Are you curious to get answers to all these questions? Read the complete article to get answers to all those questions

Before talking about this buzzword, let us initially discuss,

What is Data?

The Quantities, character (or) symbols on which operations the computer can perform the operations is known as Data. In computer, data gets stored, transmitted in the form of electrical signals and gets recorded on  magenetic, optimal, mechanical recording media.

So now let us move on to the actual topic

What is Big Data?

Big Data is the term which describes the huge volume of data. This huge volume of data includes both structured as well as unstructured data. In organization these volumes of data get generated on day to day basis through various sources. Moreover, organizations does not require this entire data. This is because this data may contain the reduntant as well the useless data. So the organizations segregate all these data into useful information as per their needs.

In other words, this big data is also refer to the fast, larger (or) complex data that is impossible to process with the traditional methods. Even though the process of storing the large amount of information is happening from the long time, the concept of big data came into existence due to 3V’s in early 2000. These 3V’s  refer as follows:


 Organization gets the data from various sources. In some cases, the data can be in terms of tens of terabytes. And in somecases it might be in terms of hundreds of petabytes. This includes business transactions, small IOT devices, industrial equipment, videos, social media, and so on. But, storage has become the most common problem in the previous decade, but today with the emergence of storage platform like Hadoop have eased this problem. Here the size of data plays a major role in determining the cost of data analysis. On the basis of volume, we can say that this volume is big data (or) not. Hence we can say volume is one of the most important characteristic in dealing with big data.


It refers to the rate with which the data is received and perhaps acted upon. Normally biggest velocity of data steams directly to be memory rather than being written on the disk. Moreover, some internet-enabled smart products operate in real time(or) near real-time and require a real-time evaluation as well as action. Moreover, this big data deals with the speed at which the data flows from different sources. These different sources includes business process, application logic, networks, social media sites, mobile devices and so on. Here the data flow is massive and continuous.


Data in the Big data gets generated from multiple sources in various formats. Here the data formats can be as follows:

Types of Big Data:

  • Structured:

Any data that can be stored, accessed, and processed in the form of fixed-format is known as Structured data. Over a period of time,  the talent in the computer science has achieved great success in developing the techniques to work with such kind of data. But today there are some spacing issues in dealing with huge amounts of data( i.e data in the form of multiple zeta bytes).

  • Unstructured:

Any data with unknown form (or) structure is known as unstructured data. Other than dealing with the huge amount of data, unstructured data poses multiple challenges in its processing for deriving the value of it. In other words, an  unstructured data is the heterogenous data source. This data source contains a combination of simple text files, images as well as videos.  Moreover, the unstructured data may also includes log files, transaction history file and so on. In some organization even though the data is present in large amounts, they were not in a position to derive results. This is due to presence of data in irregular format.

  • Semi- Structured:

A semi structuted data contains data in both the forms. Moreover, we can say that the semi strcuted data as structured form of data but not actually defined. For instance, the table definition in the Relational Data base management Systems (RDBMS).

How Big Data works?

Big data provides the way to open up the new opportunities and business models. This involves three phases as follows:


Big data is responsible to bring the data from different sources and applications.  Traditional data integration mechanisms such as ETL generally were not up to the mark. And it requires new strategies and technologies to analyze big data sets in terms of terabytes (or) the petabytes of data. Moreover, during the integration, the analyst is responsible to bring the data in a single format before the data analysis starts


As mentioned above, big data contains data in large volume. Hence the big data contains a large volumes of storage. And this storage can be on local (or) on-premises (or) on both. Moreover, through big data you are responsible to store any amount of data in any format as per the demand. Most of the people choose their storage solution according to the data currently residing. According to the recent stats, cloud is gradually popularity as they the flexible to scale the resources as per the requirement


Through big data,people can get the best analysis of the business. Moreover, people do get the visual data analysis of varied data analysis.Besides you can explore the data to make the new discoveries

Benefits :

Processing the big data includes multiple benefits as follows:

a)Intelligence utilization and decision making:

 Access to social media sites like facebook and twitter are enabling organization to fine tune their business strategies

b)Improved Customer Service:

Traditional customer feedback systems were replaced by new systems designed with these  technologies. Moreover, in these new systems big data and natural processing technologies are being used to read and evaluate the customer responses. Moreovoer, this technologies are responsible for the creation of staging area (or) landing the zone for new data.

Hence likewise, there are many use cases of big data. And you people can get hands-on experience on big data from live experts through online at Big Data online course.  I hope you people have got an enough idea regarding on big data. In my next article of this blog ill be sharing the knowledge on big data applications in  real world.Mean while have a glance at our Big data interview questions and grab the job in your dream firm

What is selenium | Kits

What is Selenium?

Make an application live in the market is not as easy as you think. This is because application development requires several steps to release into the market. This involves planning, designing, implementation, testing, debugging, monitoring, and production. An application gets executed all these processes sequentially. Among all these processes,  testing is the crucial phase in developing an application. The test result decides an application to make into production.  Selenium is the best testing tool to test various kinds of applications in the market. Would you like to know how? Read the complete articles to get the best knowledge on this tool.

Before going to have a brief discussion on this tool, let us have an initial discussion on

Need for Testing:

The world of technology is completed dominated by machines. Here the behavior is controlled by software powering it. And we cannot expect the machines to be run exactly all the time. So to make the application run the same all the time, we need to test application software and make it bug-free. This test result shows the application success rate. And this application success rate shows your business growth. This testing is necessary for all kinds of applications from small to large. Moreover, this software testing is divided into types like Manual Testing and Automation. This Automation testing is responsible to overcome the problem of manual testing.

Challenges of Manual Testing:

Manual testing refers to the testing of web applications manually by QA testers. Here tester needs to perform various test cases manually in every environment using different data sets and the success-failure rate of every transaction should be recorded.  And we cannot expect every manual testing is accurate all the time. Because there would be failures occasionally during manual testing. Hence to overcome these kinds of failures,  testers opts automation testing compared to manual testing. And Selenium is an example of this automation testing

What is Selenium?

It is an open-source tool, that is responsible for automating the test performed on the web browsers. With this tool, we can test both the mobile as well as desktop applications. This tool was originally developed by Jason Huggins in 2004. This tool suits well in developing applications across various browsers, platforms as well as programming languages. And this tool also suits well for various mobile platforms like Windows, Android, iOs, and so on.

This tool uses different drivers to support a variety of programming languages. Some of the popular languages that this tool supports are C#, Java, Perl, Python, and Ruby. Among all these programming languages, selenium web driver is popular with java and python to test different kinds of scripts. Likewise, this tool supports different browsers like Safari, Mozilla, Google Chrome, and so on. Using selenium testers can able to deliver faster test cycles by automating rapid test cases. And you people can get the selenium download even through online. Kits Selenium Online Training gives a more detailed explanation of this tool.

selenium | Kits

Selenium Tools:

This Selenium suite is composed of several different tools as follows:

 Remote Control(RC):

It is a testing framework that enables the QA (or) developer to write test cases in any programming language to automate the UI tests for web applications. This Selenium RC consists of Selenium Server and Selenium Remote Control(RC). The RC Server communicates using simple HTTP using GET/POST request. In Selenium RC, communication with the RC server is very slow. Hence this RC Server is a time-consuming process.

Integration Development Environment(IDE):

It is a firefox plugin that has donated the selenium IDE prototype to the apache selenium project. This firefox plugin is responsible for the faster creation of test cases. Here the IDE implements a record and playback model. Here the test cases are created by recording the user interactions with the browser. And these tests can be played back any number of times. Besides the advantage of this plugin allows to export the test records via different plugins like java, ruby, python, and so on.

Web Driver:

It is the first cross-platform testing that could control the browser from the OS level. In contrast to IDE, this web driver provides a programming interface to increate and execute test cases. Here the test cases are written such that web elements on the web pages are identified and the actions were performed on those elements. It is an upgraded version of Selenium RC. Hence it is much faster in comparision with RC.


It is an advanced version that allows the simultaneous execution of an application in different browsers. One of the main advantages of using the grid is that it divides the total test suite to work with different machines at the same time. This tool is very flexible and can add more functionality to the framework to create changes to their versions to get high performance.

How Selenium is different from QTP?

QTP is a functional and regression testing automation that provides the functional and regression test automation for software applications and environments. This was used by testers over QTP before selenium. Now let us have a quick look on

Advantages of Selenium over QTP:

  1. It is an open-source tool
  2. It is highly extensible
  3. Runs test across different browsers
  4. Supports various operating system and mobile devices
  5. Can execute the tests in parallel
  6. Capable of test execution while the browser is minimized

Hence likewise, there are many benefits of this tool over other testing tools.  Moreover, you people can get to know all those benefits practically from live experts through  Selenium Online Course. I hope you people have got enough knowledge of Selenium and how it is different from other tools. In the next article, I’ll be sharing you with the in-depth knowledge of selenium hq and its components, its applications in various cases, and so on. In the meantime have a glance at Selenium interview Questions and get placed in your dream firm

What is DevOps | Kits Online Training

What is DevOps?

DevOps is the most powerful as well as the most popular platform that is being used by many companies in today’s world. This DevOps culture is being used by many organizations in the IT World today. Hence today, in this article, let us have an overview of DevOps

Before knowing the overview of DevOps, let us walk through its neeed.

Need for DevOps:

Before the arrival of DevOps principles companies used to adopt various software development models like the Waterfall model. Waterfall Software development is a sequential model. Hence if one phase in the model fails, the process needs to start from the beginning. Hence we can say this as a repetitive process. Moreover, it increases the time complexity of software development. Hence to overcome these kinds of problems, we need an agile approach. Then at this movement, DevOps principles came into existence.

What is DevOps?

Many newbies argue that DevOps is a tool. Some others say that it is a framework and a few others say it is a cloud computing platform, if you belong to the same, then you are misunderstood.  This is because it  does not belong to any of these.

DevOps is a combination of two words like Development and Operations. It belongs to the set of principles that is responsible for increasing the agility of Development as well as the operations teams. These principles were designed to increase the collaboration of Development as well as the operations teams. These principles were designed to overcome the problem of the traditional software model. Moreover,   these principles were designed to increase the efficiency of software development with fewer life cycles. Moreover, these  principles accelerate the process of developing software applications and software services at high speed and high velocity. So many organizations adopt these principles as early as possible. Moreover, by applying these principles we can detect the bugs at the early stage and also minimize the risk factor of the application. Kits DevOps Online Training trainers let you know the early detection of application bugs with live use cases

what is devops | kits online trainings

Where did DevOps Come from?

It is an off-spring of agile development. This was born to increase the velocity of the project and the throughput agile methods have achieved. The need for agile development shows the ways to the origin of these principles .

What is the goal of DevOps?

The main goal of these principles  is to improve the collaboration between the stakeholders from planning to delivery through the delivery of the automation process to achieve the following goals. They are to:

a)Improve the deployment frequency

b)Achieve faster time to market

c)Lower failure  of new releases

d)shorten the lead time between fixes

e)Improve the meantime to recovery

What are the advantages of the DevOps approach?

Every decision in the organization is the key factor in the organization’s growth. As mentioned above, today most organization adopt this approach due to the following reasons:

Smart Collaboration:

This is the base of DevOps approach. And it also considered as the biggest benefit of the many application. Moreover, well-established communication between the team members saves a lot of time. Besides, this smooth collaboration reduces a lot of frazzled nerves and also reduces the waiting time. Moreover, it also reduces the bus factor.


DevOps principles were applied from the beginning to the project to scale the project as much as possible. Moreover, the principles were designed in such a way that it takes less time to scale the project environment.


Many developers today say that it is the most important factor that many people today adopt this principle.  All the products built using the these principles consist of small, independent modules where the developers can easily replace, change the components whenever required. Moreover, DevOps agility can be easily configured at any moment


Since the projects were very huge, maintaining the backup of the application is essential for the smooth running of the project. So these principles do have the capability of maintaining the last working copy. Hence in the case of event disaster, we can instantly set up the recovery (or) the rollback process. This makes the application availability with zero downtime

Speed :

As mentioned above, all the above principles were designed in such a way these principles were capable of exposing all the above-mentioned features at great speed within a short period. Moreover, the need for the these principles increases w.r.t the project complexity

Hence likewise, many advantages of utilizing the these  principles in the market today. Besides many tools like docker, chef, puppet, ansible work on the these principles. And Companies were paying the best salaries to the DevOps AWS professionals. Hence get certified  by  live experts training  at DevOps Online Course

I hope you people have gained enough knowledge DevOps definition. In the upcoming, Ill be sharing the knowledge on the life Cycle, tools,  methodologies, principles, and so on. Follow this blog to acquire the best knowledge of various IT platforms
