What is Cloud Hosting – know everything you need

Cloud hosting is the latest data management system for people who are interested to do online navigation, researches and self-pace studies. The whole data management and information retrieval take place through multiple Cloud based servers to ensure proper data management preventing loss of intellectual property. For instance, Google is the powerful resource to provide data to people. It is operated by numerous servers, which are supported by Cloud servers. Now the advantage of installing Cloud server for data mining and online site maintenance without a tech glitz.

Cloud Based Hosting over Basic Hosting Service–A Comparison

Comparison studies confirm the usefulness of the installation of Cloud computing in corporate sectors due to the availability of upgraded data management system to enhance the faster data restoration and backup file retrieval process smoothly. For this reason, if your system goes out of order, there will be no problem for you to hit Google or any other search engine from café. You can use your mobile devices to open Cloud based Google as it is highly compatible to support multiple miniature devices. Therefore, the importance of cloud base hosting online must not be overlooked. Cloud based sites are useful to those who have to store large video files, snapshots, and research oriented documents without facing trouble. The data protection is strictly maintained.

In the event of the loss of data, a computer operator has good option to retrieve data from Cloud based database. Besides, Cloud based computing service is faster. The rate of data processing and online data conversion/file sharing and instant site tracking are easily done using the Cloud based hosting system. Web pages are posted and protected perfectly. Good websites that require higher SERP rates to stay online must have hi-tech Cloud based system to help trillion online visitors to do their online researches comfortably.

Why is Raspberry Pi so popular?

Raspberry pi is a small personal computer the size of a credit card that would easily fit in your pocket. It was founded by Raspberry Pi Foundation, a UK based Electronics Company, in February 2012 aimed at educators for teaching basic computer science in schools.

Ever since its inception, it has been a big hit amongst the target market due to several reasons such as its economical price, and the ability to carry it anywhere. Just plug and play! Till date, it has shipped over 3.8 million educators worldwide. Here are some of the reasons why this tiny DIY gadget is so popular:

  1. Economical pricing – Can you imagine to get a new/used computer, whether be it a laptop or a desktop at a mere $35? That is the affordability which Raspberry pi offers. It is highly economical and designed for educators and instructors to make programming fun for the students.

  2. Fits your pocket – Apart from the Apple mini, there is no other computer that we can think of fitting your pocket. Raspberry Pi fits your pocket and is extremely convenient to be carried around anywhere.

  3. Free and open-source Linux OS built-in – While the Mac and Windows come at license charges higher than the price of Raspberry Pi, the open-source Linux operating system is free and extremely user-friendly to use. Most of the times it is Linux Ubuntu, but it can be any other operating system. The benefit of having an open-source OS is that kids and students can learn to program the OS and build new applications.

  4. Endless possibilities– There are a number of possibilities that can be built upon the Raspberry Pi foundation, such as the starter kits for laptops, HD screens and more. Many other indiegogo and Kickstarter campaigns have started springing up on board due to the number of possibilities that the small personal computer can provide. In the coming years, Raspberry Pi can set new standards of teaching for programming amongst educators.

Raspberry Pi may not be perfect in every way, but it has a lot of great potential in the coming years. Programming is an integral part of writing software applications, and most of the times, it is not fun to teach or learn. Raspberry Pi has done just that by making programming a fun subject to be learnt.

Apache vs Nginx Web server

Nginx and Apache are Linux based web servers that serve as backbone for websites in transferring data and running programming scripts and languages. Historically, Apache has been the most popular web server since its launch in 1996, and in 2009, it became the first server to exceed 100 millionth website mark. As of 2009, over 45% of the websites were hosted using Apache as their web servers.

However, since 2011, 2 years after the launch of Nginx (pronounced as Nginx), a steady downfall has been observed in the adoption rate of Apache. This downfall has been reported to be from as high as 63% to below 40%, a sharp decline of 23% over since 2011. Here are some differences between both servers, and which one serves to be better in terms of speed and performance:

  1. Architectural differences

Apache and Nginx have difference in their architecture designs. Nging is an event-based, whereas Apache is a process-based server. Both have their own set of features. However, the steady dropfall in the adoption rates of Apache has been observed due to the fact that Nginx is a much faster server than its counterpart. Moreover, since it is event-driven, Nginx server is best known for its scalability and does not allow the server RAM to be consumed heavily under heavy loads. Apache on the other hand does the opposite and hence results in degraded server performance. Nginx only requires the minimal amount of server resources to run and avoids heavy consumption of resources.

  1. Performance

Due to the event-drive process, Nginx is faster than Apache and is best used for serving static content with optimum memory consumption of server resources. It does not need to request new threads to load a process, unlike Apache. Nginx is an excellent servier for doing reverse proxies of millions of HTTP websites. However, it only uses minimum amount of resources, compared to over-consumption of resources by Apache.

  1. Ease of use

Apache has dramatically improved itself over the last few years in terms of bug fixes, and ease of use. On the other hand, Nginx is also fairly easy to use with lesser amount of time and effort required in deployment as compared to its counterpart.


Both servers are great in terms of their own features. However complete reliance just on the servers for speed and performance is just not a wise option. In the internet of things, web servers, server resources, cloud/shared/VPS/dedicated, all choices combined make a logical decision of determining performance of websites.

Service Models in Cloud computing and their uses

Cloud computing’s usage has sky rocketed within the last few years and the number of benefits outweigh other traditional data storage models. In cloud computing, there are 3 service models. A service model is defined as a type of service that is delivered to the customer. The following content highlights the different service models, their comparative pros and cons and when to use them.

  1. IaaS

Dubbed as infrastructure-as-a-service, this is the 1st layer in cloud computing and is typically used by companies requiring extra data space for faster processing. You (the client) is responsible for managing runtime, middleware, data and applications, whereas the service provider manages:

  • Virtualizations

  • Servers

  • Networking and storage

This service model is cost-efficient in a way that it saves you money and time on hiring expensive IT resources and reduces your capital risk.

  1. PaaS

This is the 2nd layer in cloud computing and is dubbed as Platform-as-a-service model in which you only manage data and applications, whereas the rest is managed by your PasS service provider. It is costlier than IasS, yet provides added benefits of managing more services. You only pay for what you use and this type of service model is best used by companies requiring uptime of applications.

  1. SaaS

This is the 3rd and final layer of cloud computing, that is also the most expensive and provides an array of additional benefits than IasS and PasS. You have complete control, freedom and flexibility to use and operate under this environment wherein all applications, data, and other services are managed by the service provider. Since your entire organization would be based on the single software, your users would feel comfortable working on it. If your team takes care of the hardware, let SaaS service provider take care of your software in upgrading them, maintaining them and assuring them bug-free. SaaS can be used on smartphones, laptops and other operating systems.


All service models as mentioned above have their own benefits. While SaaS may be tempting, it is also the costliest. On the other hand, if you have a team managing most aspects of your organization, then IasS or PaaS service models may work best for you. Prices vary for each one of these models. Each service provider such as Amazon and Microsoft have different price plans that vary from client to client. Also, as a registered member of these websites, you can always generate costing reports and run forecast analysis.

Virtualization and Cloud computing.

Virtualization and cloud computing are two different terms, often used interchangeably. Virtualization is a set of software resources that form the building blocks of cloud computing. In the simplest forms, let us take an example of Virtual Box, an Oracle software. You can run multiple instances of operating systems on it, regardless of the operating system you have installed in your system.

Virtualization separates the physical resources to create dedicated servers in a virtual environment. These servers can then be used for storing data and other purposes.

What is Cloud computing?

Cloud computing is a more recent term, that has been formed as a result of virtualization. In layman terms, 2+2 = 4, but we cannot assume 2 and 4 to be the same. It is the addition of 2 numbers resulting in 4. The same way, cloud computing is a result of using virtual machines to power dedicated servers and hardware in order to boost performance. Cloud computing is a result of virtualization, which gives powerful access to complex software and boosts enterprise performance.

Cloud computing and virtualization are interdependent on each other. For example, to leverage the powers of cloud computing, it is important to have powerful virtual servers that can be further configured.

Advantages of Virtualization

Private and public clouds offer an array of services, which can help distinguish the different advantages of cloud computing over virtualization. A private cloud operates in its own virtual environment with complete flexibility and control of usage, once the servers are bought or leased out. On the other hand, public clouds offer pay as you go services where virtual environment is provided by a third party.

Advantages of Cloud computing and Virtualization combined

Public clouds are the best when it comes to consuming benefits of virtualization and cloud computing combined. Enterprises can leverage the powers of both technologies to maximize resources, minimize costs, and run multiple operating systems without the need of having separate hardware.

How to determine? Which companies use it?

Enterprises need to first identify the need for virtualization or cloud computing. Enterprises having fewer IT staff, and higher security concerns are usually in need for cloud computing, whereas enterprises requiring greater control and flexibility of their own private cloud, go for virtualization.

Businesses should be very careful in determining the right service provider, and make a feasibility analysis for operating expenditure and capital expenditure required for virtualization or cloud computing.

 Introduction to Big Data and Hadoop

As time has progressed, data has just increased many folds. Big Data is a relatively new terminology that refers to capturing, storing, managing and analysing data that cannot be done using traditional methods. A small website may require MySQL database to store customer records. But for websites like Amazon, Ebay and Google, these companies are giants where traditional data storing and analysing techniques have failed.

These data sets are so complex and large that they require new cutting-edge methods for processing and storing. There is so much data available online and offline, that it would require years to store and analyse it. Hence, new methods and software have to be designed to cope up with such a big change.

What is Hadoop?

Hadoop is an free, and 100% complete open-source software library and framework for distribution and processing of Big Data across clusters of computers through simple programming language. Instead of relying on single server, it is designed to scale up to thousands of servers and disperse data to all systems having their own storage. This decreases data-access time and speeds up data processing and analysis. Another advantage of Hadoop is that all problems can be resolved on application end. This means that the software framework alone can provide solutions at its own layer, reducing time and cost of data processing. As a result, there is a very high tolerance of data error.

Here are some of the features of Hadoop:

  1. Open source – It is open source and completely customized for further changes. It is free to download, distribute and make changes to it.

  2. Framework provided – Hadoop is not just a software but a complete software framework with program, tools and connections.

  3. Distributed data – Data is distributed across clusters of computers, making it less risky for data loss and increases data processing speed.

  4. Huge amount of data – Hadoop has redefined data storage. You can now store huge and complex data and breaking it in blocks.

Hadoop is important in today’s age given the sheer amount of data generated through millions of websites and businesses. Hadoop is low cost, scalable, and provides storage flexibility. This makes Hadoop, an ideal platform to store and manage big Data.

We have seen that commercial software distribution of Hadoop are increasing such as Cloudera and Hortonworks. Today, large organizations should be leveraging the platform of Hadoop.

Cloud Computing security – How secure is Cloud Computing?

 What do Dropbox, Google Drive, iCloud, Box and other similar cloud services have in common? They offer, economical, scalable and safe data storage solutions that not only decrease costs and increase economies of scale, but also provide easy access from anywhere in the world.

From consumer or industrial point of view, cloud computing has started gaining attention due to the widespread benefits that come with it. But, is it really without any risks? In this article, we share our thoughts regarding the security of your data in cloud computing. Here are the top 6 most worrisome threats to cloud computing that pose serious challenge to consumers and organizations alike to keep their data safe and secure:

Data breach and theft

Nothing is more dangerous than having your data breached and stolen in the cloud, as pointed shared by analysts in the survey conducted by CSA. Virtual machines can be vulnerable to leak cryptographic keys, which hackers can use to enter any operating system in the cloud and steal data. If encryption key is the way to encrypt data, then losing this key would mean losing your entire data.

 Data Loss

Whereas a hacker can access and delete the data, the cloud service provider can get disrupted due to fire, natural disasters or other emergency situations resulting in complete data loss. Data loss may not be an issue for most of the users, but if a cloud service providers is specifically assigned the duty to safeguard vulnerable data, it can be dragged and prosecuted in the court for violating data safety laws.

Service traffic hijacking

Whenever a hacker gets access to a client’s credentials in the cloud, it is not difficult for him to manipulate data, get the customers to illegitimate websites and steal all of the important information such as credit card numbers.

Weak infrastructure and APIs

Cloud computing is a serious game, and needs to be managed and monitored using strong infrastructures and APIs.

Dos attacks

Also termed as Denial of service attacks, DoS attacks were not a major threat until recently, when cloud computing started gaining widespread populatrity and usage. Hackers can initiate DoS attacks to damage the cloud service providers and their clients in terms of financial resources. In this attack, the hacker inflates the time required to run resources, making it extremely expensive for the cloud service provider’s client to keep the data for very long.


Believe it or not, a current or former employee working with the cloud storage provide knows not only the exact location of servers but has access to networks, systems or important data. The insider can be bought by an agency or a team of hackers to steal the vulnerable information.

Cloud computing has its own merits and setbacks. Hence, it should be used with caution by companies having an extra data backup plan in case the cloud service provider is unable to meet the client demands.

Difference between SQL and NoSQL Databases

SQL (Structured Query Language) databases need no introduction. These are the de factor in database management, and most of the people in IT field are already familiar with SQL. Famous examples are ORACLE and MySQL databases. However, over the last few years, a new DBMS (Database Management System) has started gaining traction. The NoSQL database.

 In this article, we shall shed light upon the differences in between these two and in which circumstances are each of these used. Here is a list of differences amongst the two:

  1. Structure of data

SQL Database has a relational structure, which means it uses relations, also known as tables to store various amounts of data. On the other hand, NoSQL can allow free-flow operations to store data. Unlike SQL, NoSQL does not need relations or schemas. Moreover, NoSQL have dynamic schemas whereas SQL has predefined schemas for storing data.

  1. Scalability

SQL database is vertically scalable, whereas NoSQL is horizontally scalabe. In layman terms, it means that SQL databases require additional powerful hardware to increase its power, whereas NoSQL requires additional servers

  1. Querying Language

SQL is queried using the Structured Query Language (SQL), whereas NoSQL has different means to query the data having an unstructured query language.

  1. Data reliability and safety

Due to the widespread usage of SQL in modern applications, security is one of the main concerns of developers and users. SQL, is hence still considered better option than NoSQL when it comes to data safety and reliability.

  1. Customer support

If you ever encounter a problem with SQL, there are both free and paid versions of support that you can get from an active community of SQL developers and users due to the decades long history of this DBMS. If you need support for NoSQL, you may find it very hard due to the limited material available.

  1. Complex data querying requirements

SQL has been developed and improved over time, whereas NoSQL is just a new player in the field. Mostly, it is the relational databases (SQL) that have been setup and deployed for managing and storing data. There is still a very long way for NoSQL to go.

The Popular TournamentLinux vs. UNIX

Majority of the people have never given a thought about purchasing an operating system. It comes with the computer when they buy it. A large number of people use Microsoft Windows and have come to expect computers to work in a typical manner; some people have had rationale to even wonder what an operating system is. So picking an operating system is looking at the big portrait of how your computer works. Nearly everyone is familiar about operating systems, such as Windows, iOS, Android or Mac operating system.

Today, get yourself introduced to the other two famous operating systems namely Linux and UNIX. Here you will know about the difference between Linux operating system and UNIX operating system. Both the Operating systems possess similar components but cater hugely diverse purposes & performances in today’s business world.

Mentioned below are few main differences between Linux and UNIX:


 Linux can be far more flexible in comparison to UNIX, as it can fit on almost any hardware excluding a few. Linux is formerly developed for Intel's x86 hardware, ports accessible for 12+ CPU kinds counting ARM. But UNIX OS is very constrained when it comes to the compatible hardware, for example HP-UX is obtainable on PA-RISC and Itanium machines. Solaris is existing on SPARC and x86. AIX is just for the power processors, etc.


 Actually, Linux can be without cost distributed, downloaded, spread through books and magazines, etc. There are also paid versions in Linux, but they are normally cheaper compare to the Windows. On the other hand, UNIX is a paid operating system with different rates for different versions.


 Linux can be set up on an assorted variety of computer hardware, tablet computers, ranging from mobile phones, video game to mainframes and latest desktop, environment, applications, and computers. However, the same cannot be done with UNIX.


Kernel is called as the hub of any operating system. Now as put in plain words in the history part, Linux is just a kernel and integrating it with other elements like compilers, editors, and libraries forms it as an Operating System.

The source codes for most UNIX kernel, in particular the commercial versions, is not offered free. On the other hand, most Linux Operating system source codes are without fee on hand under the GPL and can be read, customized, and used by all and sundry.


 Linux operating system is used by everyone from home users to computer fanatic and developers. On the other hand, UNIX operating systems were developed mainly for mainframes, servers, and big enterprises except OSX, Which is planned for one and all. While, the UNIX setting and the client-server program structures were important elements especially in the development of the Internet.


 Actually if meticulously observed there isn’t much dissimilarity between Linux and UNIX in terms of majority of the commands and functioning that too from an end-user point of view.


 Linux has had about more or less 60-100 viruses found till date. None of them actively is spreading nowadays. And an approximate estimate of UNIX viruses is somewhere between 85 -120 viruses reported by the latest researchers till date.

 Thus, choice between Linux & UNIX from rest of the today’s operating system for an individual solely depends on ones business requirements.

 Virtual Private Server vs Dedicated Hosting

The two top of the range hosting options for customers are dedicated hosting and VPS hosting. Both have their own pros and cons in terms of performance, price, and allocated resources for web hosting needs. If your website has grown in terms of traffic and revenue, then you may consider either VPS or dedicated. Let us discuss both herein:




1. VPS hosting

With a VPS hosting account, you get access to shared CPU with other virtual machines, but guaranteed access to specified RAM and storage. A VPS server is flexible and often more economical as compared with dedicated server. In terms of control and customization, VPS and dedicated server can be rebooted and further modules/software can be installed easily as provide by your web hosting service provider. Here is a snapshot of VPS hosting:

  • Economical price than dedicated servers
  • Flexibility to grow as your site grows
  • No technical limitations in terms of domain hosting
  • Assigned control over RAM and storage
  • Shared CPU resources with other virtual machines
  • Click script installation, backups, SSL certificates, etc.


2.Dedicated Servers

Dedicated server provides the power, flexibility and complete control over the CPU resources that you can use. If you are looking for the best hosting solution with robust server speed and flexibility, the dedicated hosting is for you. As with VPS plans, dedicated hosting prices also vary in terms of storage capacity, RAM and disk speed. It is the most powerful website hosting plan available and the one providing complete control to the customer. Here is a snapshot of dedicated hosting:

  1. 100% control over computer resources

  2. Your computer resources never get shared with anyone else

  3. Heavy upfront costs and investments to setup a dedicated server

  4. Extremely powerful and fast

  5. 1-click script installation, backups, SSL certificates, etc.



When choosing in between VPS and dedicated hosting, cost is the biggest determining factor. If you are just experiencing growth on your website, it is recommended to get VPS hosting, which shares similar benefits of dedicated hosting and is also nominally priced. On the other hand, if you own a large website with millions of page views per month, you would want dedicated hosting with complete control over your computer resources. An average high-end dedicated hosting is not less than $500 per month, whereas VPS plans start from as low as $15.00. Hence, considering the sheer costs of setting up a dedicated server, VPS hosting is a good choice for small to medium sized businesses looking for economical hosting solutions.
