Server Virtualization – Background Information and Advantages

Server virtualization is the act of sectioning one server into multiple parts. The solitary virtual environments go by several names, but the most common is virtual private networks (VPN). Other terms used to describe these divisions include containers, guests, emulations, and instances. In most cases, each portion of the server is able to run its own autonomous operating system while all of the portions run off of the same underlying hardware.

There are three common methods of server virtualization:

Virtual Machine Model
Paravirtual Machine Model
Virtualization at the operating system

Virtual and paravirtual machine segmentations allow for multiple operating systems. Virtualization at the operating system only allows a single operating system for all users.

Similarly, virtual and paravirtual machine models function using a host / guest paradigm whereas virtualization at the operating system works somewhat differently.

Dividing a single server into multiple virtual private networks during virtualization can be viewed as part of a larger trend in IT which includes workload management, network virtualization and storage virtualization. These sorts of activities all serve as components in the grand scheme of creating systems that can self-manage themselves referred to as autonomic computing.

The Advantages of Server Virtualization

The primary rationalization for splitting up a server is consolidation of small servers onto a bigger one. This is such a common occurrence due to the cost benefits associated with such a migration. Also, a migration has no effect on the operating systems or applications used.

Migrating several mini-servers onto a larger one reduces the amount spent on:

System Usage
System Maintenance

Another advantage of server virtualization is that it gets rid of server sprawl, a situation where multiple under-utilized servers consume more space and resources than they require for the tasks they perform. This increases the amount of server availability as well as the amount of work that can be done by that server.

An additional positive is the simplicity involved with replicating servers. Standard virtual server builds greatly reduce the amount of time necessary to deploy a new server.

Server virtualization also compensates for the amount of activity each user performs. This autonomic computing aspect provides efficient designation of resources and maximum efficiency.

Fix Windows Blue Screen is Not That Tough!

Fix windows blue screen! Well, this is not a very major problem with your computer system. If you are facing such a type of problem don’t be so tense because there are some easy procedures that can guide you a lot to solve these problems.

5 Steps That Will Help You Become a Web Developer Even If You Have No CS Degree

Being a web developer is a very in demand profession especially when everyone is shifting to the internet. In this article I will provide you with an overview on how to be a great web developer. No Computer Science degree required.

Study HTML and CSS
HTML or Hyper Text Markup Language is not really a programming language but it’s the language that every web page on the internet is written in. The good news is that it’s very easy to learn and understand and there’s a good chance that you might know it already. I suggest that you download Notepad++ and just write and edit HTML. Learn the proper web standards and create your own website no matter how basic it looks. Speaking of looks, while HTML provides your website’s structure, CSS or Cascading Style Sheets provides its layout and design. Familiarize yourself with the different CSS properties and I’m sure with enough practice you’ll be styling those HTML pages that you’ve done. I suggest that you concentrate with positioning the elements because you’ll use that skill a lot in your career.

Study a web programming language like PHP and one database language like MySQL
Although there are a lot of languages available, PHP is the language of the internet. It powers a lot of top sites like Wikipedia, Facebook and Flickr. A lot of programmers would suggest against PHP as your first language but I think that it’s one of the easiest languages to learn and setup. There’s a myriad of tutorials out there designed no matter what your background is. A prerequisite though is that you have to know HTML. Also setting up your development environment in your desktop computer is as easy as double clicking an installer and creating your files on the web server’s directory. Download, install and read the instructions for XAMPP if you’re using Windows and MAMP if you’re on the Mac. Most PHP tutorials covers or provides more tutorials for learning a database language like MySQL. You need MySQL to store user input/data and to service them with that data the next time they visit your website.

Practice makes you better
It’s cliché but there’s no better way of learning how to program than to practice. Just program a lot of websites no matter how small they are. Create your own blog, create your online portfolio, there are a lot of information out there that needs a platform and you can provide that. Start creating!

Make Google your best friend
Everything that you need to know about becoming a programmer or web developer is in Google and the best of all they’re available for free. The key here is knowing where to look and how to look for the information you are looking for. A tip I can give you is describe the information you’re looking for in keyword phrases. For example if you’re looking for the syntax of an If…Else statement in PHP, just type in “If Else PHP” it’s that easy. Never settle on a website and try to learn from a lot of resources. It’s like gaining the experience of tens of master programmers.

Never stop asking questions
Develop that desire to know the craft of programming. Join forums, comment on blogs. There are myriads of websites that promotes interaction with other developers. You should use them to your advantage. Never stop learning and have the passion to be the best programmer that you can be.
