What is Cloud Hosting- A Beginner Guide

Let’s understand the meaning of what is Cloud Hosting?

Here, the word ‘cloud’ means a large cluster of computing technology which is owned by a large enterprise. Thus Cloud Hosting is an enterprise-class of web hosting or you can say a website hosted on clustered servers where online operations are not concentrated to a single server, demands for performance and high availability of the website or web services.

Cloud Hosting is a new hosting solution which is suitable for applications such as Web2.0 services, SaaS (Software as a Service) and Virtual data center. The hosting is a style of computing that combines the features of distributed computing and virtualization so that an on-demand computing via a network of computers working as together one.

The software safety aspect for keeping everything hosted, where regular backups and upgrades to the software are there to maintain all your information. This is something which doesn’t secure your PC, a lot of information gets lost when upgrades occur.

In a virtual environment, load balance, security, and hardware resource are handled. All the data that you create and use within Cloud computing applications and processes are stored on the Internet and not on one computer. So you can use the application and the data from anywhere as long as you have access to the Internet.

This hosting service enables you to upload your web applications and associated data to the hosting service. Your web application is distributed across a cluster of servers. As your web applications, as well as associated data, are hosted by the cluster, so any failure or downtime on any one of the servers do not affect your applications. You get the advantage from the levels of bandwidth, storage, and processing power designed for applications.

There is a service provider who decides which sites need bandwidth and processing power by detecting how much traffic they are receiving in real time. Thus, lots of space capacity available in the system by this set up.

Now, we hope you understand well about the concept of Cloud Hosting. Its main advantage is its ability to scale by adding more servers to the grid. You will find more articles on Cloud hosting on the same site.

Know why Virtual Machine is important for Cloud Computing?

Service providers of Cloud computing are using virtualization technologies in order to offer cost-effective access to computing resources with the Internet and also to gain the most from virtualization, virtual machines need to be co-located on the same physical server.

A virtual machine in computer science is a software implementation of a computer that executes programs like a real machine. It is used to create a virtual environment, which is called as virtualization. Virtualization enables the user to see the infrastructure of a network through a process of aggregation and can also be used to access multiple operating systems at the same time. A virtual environment is used solely for applications and not for operating system kernels.

Virtual machines are divided into two main categories based degree of correspondence and on their use to any real machine. This machine provides you a complete system platform that supports the execution of a complete operating system so that the user can operate software located on the computer platform.

There are so many different types of virtual machines, used to refer to hardware virtual machine software also called as a virtual machine monitor or hyper visor. This type of machine software makes it possible to run multiple executions on one computer. With the help of the hardware virtual machine software, the user has a private machine i.e. fully functional hardware which is separate from other users. Hardware virtual machine software also helps users to restart and boot their machines quickly.

The application is isolated from the computer being used with virtual machine software. This software can be used on various computer platforms. So, this is possible to create separate versions of the same software for different computers and operating systems. Java Virtual Machine is a great example of an application virtual machine.

A process virtual machine is designed to run a single program. An important characteristic of a virtual machine is that the software which is running inside is limited to the abstractions and resources provided by the virtual machine.

The Process Virtual Machine is a common foundation for graph based execution languages. The Process Virtual Machine can have three main characteristics:

• Processes can potentially include wait states from the perspective of the process engine and be ‘long running’
• The process expresses some kind of execution flow
• Processes are represented graphically to facilitate communication between all stakeholders

So, we can say that a virtual machine can also be a group of computers that work together to create a more powerful machine.
