Data visualization: Essential For Big Data

Data-visualization-Big-DataAs we work with volumes and data varieties increasing, the old saying “a picture is worth a thousand words” becomes more real. A simple example is to use the subway of a big city like London. The tube, as it is called, has 11 lines and 270 stations. In theory, the basic information is a list of stations in alphabetical order and names of the lines. But try this … Compare the alphabetical list with the map. It is crystal clear that trying to go from one station to another in hands only an alphabetical list is extremely exhausting. In own Wikipedia link appears the tube map. It is clear how to get from one station to another, that line pick up and even know how many intermediate stations exist and will need to change line, in a conspicuous and easy way. A picture is worth a thousand words well.

This example shows how important is data visualization. In a spreadsheet, it is difficult to identify trends or do correlations between data. But with graphic images our perception of numbers changes. We can identify very quickly which product sells more and which shop is more profitable.

The concept of big data increases the potential of the analyzes. Let’s take the example above the shops. Analyzing only internal data, we can identify which stores are more profitable and which products sell more within our company. We can take corrective action in case of deviations and negative trends. But what about when we see a drop in sales in a given region? No external data, as the economic situation in the region, our actions will have little effect. If we know the economic crisis, we can, for example, change the product, mix to lower unit prices. Therefore, the concept of big data, despite the big word draw attention, not just volume. A huge amount of data, but without references to help me identify the real causes of the decline in sales is not very useful. Variety, that is, access to other data sources (usually external) allows me to have a broader view of the context. Here simplistically, Big data is internal + external environment context.

Great, we took an important step. But without a good visualization tool, this mountain of data will not help us much …

With view of modern techniques, we are able to identify patterns or data correlations which were previously invisible. Asking the right questions, we can identify things that are happening, or will happen, if correctly identify trends. Not able to looking at a spreadsheet… By the way, David cites a phrase that is worth repeating here: “visualization is a form of knowledge compression”. A single image can compress a huge volume of data in a color graphics. Therefore, only with views, you can understand immense and varied amounts of data.

After all, the vast majority of the information we gather as human beings is visual. Research shows that the human retina can transmit 10 megabits per second. Second comes the hearing, with 1/10 of this capacity. It is natural that we can explore the potential of visualization techniques to analyze and correlate data more efficiently.

An example of the potential for exploitation of databases is Google’s project, “Public Data Explorer“. Using concepts of big data and dynamic views can break these ideas and make much more correct and accurate business decisions. In fact, as we have more data, the more important the ability to view them, distilling this immense and varied volume into useful information.

Visualization techniques are now extremely important for the generation of value of the concept of big data. After all, big data is not only the concept on data, but how we can extract insights and their intelligence. And visualization is the master key to it.


Recognize the advantages of Linux Operating System

If you are interested in Linux web hosting and still feel that Windows is the best option, do not worry because we will show you some of the advantages of Linux. In fact, there is no relationship between the operating system you use on your PC with using the web hosting environment. The remote server is where the files of your site will be hosted, and you do not need to worry about losing space on your hard drive. Now that we have eliminated at least one myth, let’s talk about serious things about the Linux operating system and because it offers advantages in several ways such as Web site hosting solution.

Lowest price for the service

To do your shopping on the web hostings market, you will find that Linux hosting packages are much cheaper than Windows accommodation. This is because the software that comes included with the Linux web hosting plans have no costs or licensing costs are much lower than Microsoft products. According to the success of Windows XP, Microsoft has enabled the activation policy that limit users to install a copy of Windows operating system on your computer. What in many cases, what you can do is take the Internet Linux and install it on as many computers as you want.

Dependibility proven

While the Microsoft Windows operating system is used by millions of people around the world and business, Linux is now increasingly used in the world of web hostings. For several years, Linux servers are known for their speed, stability and reliability. And although Microsoft has made significant improvements in its systems, the number of cases of crashes in the operating system is much higher compared to Linux servers. With all this, Linux is better in terms of networks and is safer.

Built for the Web

The Linux operating system supports a wide variety of technologies that facilitate the creation of dynamic and interactive web pages. Where Windows is compatible with Microsoft technologies such as ASP and ASP.NET, the Linux platform integrates Perl, PHP and the increasingly popular language – Ruby on Rails. When used in conjunction with the powerful system of MySQL databases, you can create simply spectacular sites.

What is your type of Linux?

Originally released in 1991, Linux is becoming an increasingly popular choice for use as the operating system of the computer or laptop back home. More and more home users are finding this solid alternative to Windows or Mac OS X. While Linux is now to appear in the homes of users, it is a solution used in the academic environment and the web server. Unlike commercial operating systems, the Linux source code is open source, with several programmers contributions of communities that are always working to improve the product in general. The result is several operating system changes. There are several Linux distributions and although all have as the basis of the code, each distro is developed to think about specific needs. This article will talk about some of the most popular Linux distributions, you can find when choosing a web hosting service provider.


Ubuntu is one of the most popular distributions and focused distro for the consumer. This is because the platform is designed to be more like Windows 7 than with a solution to web server. Indeed, it has several features that can be compared with Windows. With that said, Ubuntu becomes a solid choice for the sites hosting environment and can actually be used as a server operating system.


As you may have noticed, Kubuntu is very similar to Ubuntu in terms of operation and functionality. The big difference between these two platforms is that they use different file systems. Apart from that, both operating systems have the same features and are easier to use than other Linux distros. This is an advantage for administrators who often need to deal with the complexities and challenges of web server management.


Debian distro is another widely used and who knows, is one of the most common in web hostings. It is also more difficult to use distro. Although Ubuntu and Kubuntu are based on this platform, Debian is not necessarily easy to use. However, this particular platform has excellent scalability and is very flexible.


Fedora is a Linux distribution that light often comes free with many plans for dedicated servers. These system is based and sponsored by Red Hat Linux, who holds the commercial distribution that is more competitive with Microsoft Windows. With regard to desktops, Fedora is often used on older computers simply because have low system requirements and use fewer resources. However, this system increases its power as a web server.


Means Community Enterprise Operating System, CentOS is another distribution based on Red Hat Linux. However the source code is available under the GPL license. Due to Red Hat, CentOS benefited greatly from commercial development in stability, performance and security. An increasingly popular option on dedicated servers and virtual private servers.

Increase Efficiency of Your IT Infrastructure with Cloud Computing

Often due to the new technologies and the changing trends, CIOs face countless challenges. Two of such challenges are: The revolution of smartphones and tablets (i.e. BYOD – Bring Your Own Device). Another is the loss of control of the use of IT, when IT managers are no longer able to decide about their IT infrastructure or in-house data centers.

The reason is very simply, if you go beyond BYOD, we have cloud computing technology available in the market which enables user to utilize computational power and services without getting CIOs involved in the process.

These moves accelerate the wear process, already underway in the areas of IT, viewed by many companies as specified providers of support, without greater involvement with business strategies. If this is the ambition of IT, okay. It is fulfilling its role, however, it runs the risk of seeing your status going down every day. Nothing prevents from, over time, be replaced by other services, which providers more flexibility and are cost-effective. In year 2004, a jounalist named Nicholas Carr discussed this issue in his book “Does IT Matter?” which was one of the best and recommended book for reading.

Arguably, we can see that now companies are seeking at and using IT strategically, however these examples are the exceptions, not the majority. Given this framework, IT must modify themselves and transform. They must assume another role, acting not so reactive, but proactively, looking directly towards contributing to the revenue generation of the organization. This change requires a new mental model for IT managers. It has become necessary for companies to get out from the comfort zone, where the world is connected to the ERP (Enterprise resource planning) implementation, e-mails and infrastructure, and enter a world of “pull” innovation. Enter a world of applications described at least as “unusual”, comparing their own infrastructure with Internet companies in the world and not just with enterprises within the same industry or the same size.

In order to be developed for the Internet, enterprises and organizations need to leave the world in which they are developed for the intranet applications.

Cloud computing hosting can be a powerful weapon to offer this transformation in IT and has expanded quite rapidly. In a survey conducted by IBM in conjunction with the EIU has proved this fact that cloud computing is a quite powerful tool which can help in IT transformation. In a poll conducted, around 600 IT executives and businesses participated. As a result, it was clear that about 72% of companies worldwide make use of cloud computing or cloud-based services. Also, the figure of cloud computing users (enterprises and organizations) will rise up to 90%.

Moreover, the other survey conducted shows that almost half of the U.S. companies have adopted a policy of “Cloud First”, i.e. preference to cloud computing based solutions would be given in any decision to adopt technological solutions.

Today, most of the SMBs still see cloud computing as a way to improve the efficiency of their infrastructure, however, is not recognized as a force for itself leveraging IT transformation. The research has also shown signs of Economist Intelligence Unit changing this scenario. Most of the companies have started identifying that the cloud-based services can help them accelerate business innovation and the trend “cloud and leverages innovation” is likely to accelerate in the coming years. The survey showed that while efficiency in IT infrastructure is the driver of short-term, most companies already understood that, strategically, the cloud will have a key role.

Thinking “outside the box” and forgetting the current model of buying on-premise hardware and software (based on the model CAPEX), will it be replaced by another product, anchored in OPEX (operating expenses)? What could we do if the computational resources available to us were unlimited? What could we do if we could, quickly and inexpensively develop new products and services? Can we leave the model to provision computing resources to test an application that takes weeks to twenty minutes? What if the iime for installation of an OS decrease from day to day half hour? What if the design and delivery of an application plunged and have to wait for months?

An interesting examples are Netflix, which can withstand critical variations of computational demand simply allocating more virtual servers without maintaining your own data center. Or a small e-commerce business, that can run an analytic application that analyzes a billion page views generated on monthly visits to your site in a cloud of virtual servers, thereby achieving what once only large retailers could scale with their own servers.

The survey conduced by Economist Intelligence Unit (EIU) have shown three different models, each varying degrees of opportunities, but also varying degrees of risk. A disruptive company can achieve a unique benefit by taking the lead and creating a new market, but at the risk of going into a business model unproven and possibly unsuccessful.

So with cloud computing being seen as a strategic weapon, not just an alternative to improve IT efficiency, we can transform the very limited role of your IT provider to support an active business. It is at this point that begins to make sense of a sentence said by Gartner, untranslated here not to lose its effect: “In 2021, cloud computing is simply computing, corporate office parks are senior housing facilities and the IT organization of the future has been absorbed by the business.”

  • Internal IT becomes an internal cloud
  • IT becomes a services broker
  • IT will become a function of the business
  • Cloud technology enables businesses and IT to create and deliver value in fundamentally new ways.

Helps to build enduring customer relationship: Businesses can obtain clients insight and utilize it to improve the quality of products & services as well as developing trust and loyalty among the constituents.

Helps in improving the speed and skills: With cloud hosting services, businesses can easily optimize and accelerate the delivery of IT computing resources and services and serve them with a better and flexible business model.

Helps in delivering IT without boundaries: Cloud computing can also aid businesses in unlocking the value of their new IT and business processes that breaks down the traditional silo, simplifying the access to the enterprise data and connect people across your ecosystem.

Helps in transforming the economics of IT: It can also aid companies in improving their speed in delivering the new offerings and services with better and enhanced models like self-service and deployment.

Well, this requires that IT managers and business executives take together the IT strategy (cloud should not be exclusive IT, because it is much more than technology infrastructure), with goals and business objectives to be achieved in the short and medium term. Evaluating a good cloud hosting india provider is much important. Hence, make sure you have a list of your needs in hand and identify the right kind of tools that will help you improve your businesses processes.

Cloud Computing Models: Public VS Private VS Community VS Hybrid

Cloud computing is a unique computing type that provides access to the appropriate network and on-demand set of configurable computing resources such as networks, servers, storage, applications and services. These computing resources can be provisioned and released quickly and without much effort, management and interaction by the cloud hosting services provider.

The term “cloud” is commonly used to represent the provisioning of computing resources through Internet.

Types of Cloud Computing Model

There are four different types of cloud computing model or cloud infrastructure. These models are distinguished based on the ownership of the cloud infrastructure. Following are the four types of cloud models:

  • Public Cloud Infrastructure
  • Private Cloud Infrastructure
  • Community Cloud Infrastructure
  • Hybrid Cloud Infrastructure

Let’s have a look at the cloud computing models definitions and its advantages and disadvantages.

Definitions, Advantages and Disadvantages of Cloud Models

Definition of Public Cloud

It is a type of cloud in which the infrastructure and logical resources that are part of cloud environment are available to the public via Internet. This is usually owned by a provider who manages the infrastructure and services offered.


  • Increased scalability and unlimited resources;
  • Resource efficiency via pay-per-use model;
  • Time and cost savings.


  • Sharing of Infrastructure with multiple organizations;
  • Lacks of transparency, as the clients are unaware about the same resources and storage being used by other multiple services.

Definition of Private Cloud

This is a computing model where a cloud is privately implemented within the corporate firewall and is under the control of the organizations IT department.


  • Compliance with internal policies;
  • Ease of collaborative work between distributed sites;
  • Complete control over the resources.


  • High cost material;
  • Hired infrastructure unit;
  • Return on Investment (ROI) is slow.

Definition of Community Cloud

This computing model is happen when two or more organizations form a partnership to implement a cloud infrastructure with a similar goal-oriented and a common security framework and privacy.


  • Compliance with internal policies;
  • Cost Reduction by sharing of infrastructure and resources;
  • Return on Investment (ROI) is fast.


  • Managed by organization or third party;
  • Hired infrastructure unit.
  • Definition of Hybrid Cloud

The hybrid cloud is a broad term involving a joint use of multiple cloud models or infrastructures any of the above three types, which are kept as separate entities, however which in turn are associated by standardized or proprietary technology, offering data and application portability.

Advantages and disadvantages of hybrid cloud are same as those cloud models used to form a hybrid cloud hosting environment.
