Before writing this article, I was curious to find how fares virtualization, running a little of technical articles, since the intention was to bring this information to small businesses. Thus, I searched on Google and Bing: virtualization + “small business”, anyway, with the plus sign and quotes, to bring only things with the term small business. I confess I was amazed to see 15,200,000 results on the first search engine and more than 1,84,000 in the second.

After all, it seems we have reached a moment I saw long ago, in which entrepreneurs were uncertain about buying a computer or investing in stocks, to make a home page more professional or hire more people. I am convinced that there’s more to ask if we need a virtualization as we did previously with computers and internet. Who does not use is simply wasting money by spending more for less.

In deciding to write about virtualization, I thought Again… “What’s New?”, “What can explain and show a different way than it is already seen and read through the websites, newspapers, television and e-mail?”. I could spend hours talking about the various types of virtualization, the numerous concepts that have already invented and further complicate the understanding of the subject.

Nowadays you can find virtualization for all tastes, so that soon will ask: – Do you want a virtualization strawberry or raspberry? Virtualization is simply doing more with less, and in short, is to turn a computer into 3 or 4, where before it took only one at a time, you can now use several at once. Mandatory platforms? Not anymore. Now we can have “Windows running on top” of Mac applications made for Windows 1998 or XP running perfectly on Windows 7. All virtualized. Logically, the concept extends to much more than that, but it’s a good start.

When we see the “big players” of technology, including IBM, Microsoft, Citrix, Oracle, Dell and ESDS  involved in this issue, there is always that feeling: – “That must be very expensive! Not for me.” But in fact what we found is that most of these players already offer virtualization solutions at no cost. For example, Microsoft’s virtualisation hypervisor called Hyper-V is offered for free. There are projects that turn iPhones in Thin Clients and free applications can access remotely virtualized stations that are running on Windows.

You know that pile of old computers and depreciated in your company? Spread of the virtualization may perhaps be the next workstations of employees.

Currently there are several courses about implementing virtualization in enterprises and various forms of application of it in our daily lives, which is already in need of breath so we can move forward to improve our profitability and quality of life.

The concept of cloud computing is Quite fashionable today and it is treated differently. It is the image of computing in which IT resources with a high degree of scalability are provided to users in the form of services through the Internet. A pool of managed computing infrastructure with a high degree of scalability is the provision of paid services on the placement and implementation of client applications.

And as per Wikipedia “cloud computing treats simple Technology Data Processing, in which software is made available to the user as an Internet service”.

In fact, “cloud” is a metaphor for a remote data center computing, to which access is given on the basis of payment for pay-as-you-go (pay per actual use of the service computation). Thus, the software is actually provided to the user as a service. Cloud computing user does not need to worry about any infrastructure, nor on the actual software, “cloud” successfully hides all hardware and software components.

And Intel shares the concepts of architecture and cloud-services. The first category includes the components of a dynamically scalable capture of resources, based on virtualization technology or software environment with horizontal scaling. The second – as a rule, paid services that users receive via the Internet. “Cloud” architecture can be constructed within the local network. Unlike traditionally distributed or service models, cloud computing is based on a dynamic architecture and the user pays only for the functionality, which really enjoys. The scope of cloud computing may be different – this, for example, online mailboxes, social networks, specialized search engines, online financial services cloud computing and other applications of Web 2.O.

Despite the fact that cloud computing is the concept that is still relatively young, already made projections of its future development.  In the first (2007-2011), there will be many pioneers, and their new development will ce launched in the market rapidly. Further, roughly from 2011 to 2013, will begin a consolidation phase – some vendors leave the market, while others merge with more successful competitors. And in 2013 comes the “golden age” cloud computing.

Among the pioneers of the market of cloud applications and services, including quite large manufacturers, such as Google, IBM, Microsoft, SAP, Oracle, etc. Microsoft last fall announced a platform for Windows Azure, based on Windows 2008 Server.

Along with additional services, including Windows Live, a portal solution to SharePoint, this OS will be a comprehensive solution for creating and deploying applications for online computing. A similar system along with cloud web hosting services is introduced by ESDS - its Virtual Data Center Operating System platform create and manage the data center.

A number of solutions (both hardware and software) in the cloud computing is based on the architecture of Nehalem. The Dynamic Power Node Manager, and Data Center Management Interface, allows not only to optimize power servers, but also reduce the cost of managing data centers.

Communication products supporting virtualization and cloud computing is delivered by Cisco. Cisco Nexus family of switches replenished Nexus 7000 Series, 5000 and 2000 models. Model Switch Cisco Nexus 7018 chassis is equipped with 18 slots and supports up to 512 ports Ethernet. Nexus 5010 also supports Ethernet, and Fibre Channel, and the model of Nexus 2000 is to expand the bandwidth of a server farm.

Many IT experts say that in the near future, cloud computing will be included in the top list of technological trends, and certainly could become a very profitable service for those companies that will seriously deal with them and constantly develop them for better benefits.

The Apache HTTP Server is a robust, commercial-grade open source Web server developed by the Apache Software Foundation. Red Hat Enterprise Linux includes the Apache HTTP Server 2.0 as well as a number of server modules designed to enhance its functionality.

The Apache HTTP Server, commonly referred to as Apache (pronounced /??pæt?i?/), is web server software notable for playing a key role in the initial growth of the World Wide Web.In 2009 it became the first web server software to surpass the 100 million web site milestone.Apache was the first viable alternative to the Netscape Communications Corporation web server (currently known as Oracle iPlanet Web Server), and has since evolved to rival other Unix-based web servers in terms of functionality and performance. The majority of web servers using Apache run a Unix-like operating system.

If the Apache HTTP Server configured with the HTTP Configuration Tool in previous versions of Red Hat Enterprise Linux and then performed an upgrade, you can use the HTTP Configuration Tool to migrate the configuration file to the new format for version 2.0. Start the HTTP Configuration Tool, make any changes to the configuration, and save it. The configuration file saved will be compatible with version 2.0.

Features of Apache HTTP Server 2.0

Apache API — Modules utilize a more powerful set of Application Programming Interfaces (APIs).

Filtering — Modules can act as content filters. Refer to Section 10.2.4 Modules and Apache HTTP Server 2.0 for more on how filtering works.

IPv6 Support — The next generation IP addressing format is supported.

Simplified Directives — A number of confusing directives have been removed while others have been simplified.

Multilingual Error Responses — When using Server Side Include (SSI) documents, customizable error response pages can be delivered in multiple languages.
