As you can appreciate Cloud Computing is really in its infancy and is therefore likely to change drastically over time. Cloud computing is basically computing service. In this computing service model, all the servers, networks, applications and other elements that are associated with data centers are made accessible to IT and end users via the Internet, in such a way that allows IT to acquire only the type and amount of computing services that they actually need. The cloud service model varies from traditional outsourcers in a way that customers do not turn over their own IT resources to be managed and controlled. Instead they plug into the “cloud” for infrastructure services, platform (operating system) services, or software services, treating the “cloud” much as they would treat an internal data center or computer performing the same functions, essentially as a service.

The main services provided by cloud computing service model can basically be divided into three main categories namely Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).

Infrastructure-as-a-Service (IaaS) provides virtual servers with unique IP addresses. Also, it provides blocks of storage on demand. Customers benefit from an API from which they can control and manage their servers. Moreover, because of the economies of scale and specialization involved, this not only brings advantages to the users but also to the business providing the infrastructure. This service is also known as utility computing since the customers can pay for exactly the amount of service they use, like for electricity or water. It provides grids, clusters and virtualized servers, networks, storage and systems software designed to expand or substitute the functions of an entire data center. IaaS allows an internet business to develop and grow on demand.The best example of IaaS is Amazon’s Elastic Compute Cloud [EC2] and Simple Storage Service, however, IBM and other traditional IT vendors are also offering services, as is telecom-and-more provider Verizon Business.

Platform-as-a-Service (PaaS) is a set of software and development tools that are hosted on the provider’s servers. Developers can create applications using the provider’s API’s. It should be taken in account by the developers that there are not any interoperability standards maintained as yet, so some providers may not let them to take their application and put it on another platform. PaaS basically provides virtualized servers on which users can run existing applications or develop new ones without being worried about maintaining the operating systems, server hardware, load balancing or computing capacity. PaaS also allows a lot of scalability by design. Google Apps is one of the most famous Platform-as-a-Service providers. Other good examples include Microsoft’s Azure and Salesforce’s Force.com.

The third type which is Software-as-a-Service (SaaS) makes the broadest market. It is the most widely known and broadly used form of cloud computing.In this service, the providers allow the customers only to use their applications. The software through user interface interacts with the user. SaaS offers all the functions of a sophisticated traditional application. However, these applications are provided through a Web browser, and not by a locally-installed application. It reduces worries to a great extent about application servers, storage, application development and other common concerns of IT. Salesforce.com, Google’s Gmail and Apps, instant messaging from AOL, Yahoo and Google, Twitter and VoIP from Vonage and Skype are some common examples of SaaS providers.

In conclusion cloud computing is essentially a type of computing service model that can be used at anytime, that increases on demand and decreases when you don’t have a demand, making it something that appears quite attractive especially in the current economic climate.

The term web server is used to refer both to the computer on which are hosted the websites and to the software that delivers websites content or performs the required operations to build the dynamic content which is later served to the user.

Let’s see the difference between the two more in depth:

Web Server (Computer)

Every website must be hosted on one or more computers (server, web server): the hardware employed to build this computer can be extremely simple or extremely complicated, groups of multiple servers (clusters) might be used, sharing the load of the requests coming from the web. This particular configuration is required when a website gets massive traffic.

On the other hand a web server can be a computer as simple as your home computer, or a computer with a particular case designed for data center usage. These servers can be mounted inside server racks to optimize space. These servers are usually wide, deep and very thin. The width is 19 inches, it’s standard so that servers can be mounted in any server rack.

Rackable servers can have different heights. The base unit the rack Unit, commonly referred to as U, which is 1.75 inches high. Most common sizes for servers are 1U, 2U and 4U depending on the number of the components (disks, CPUs, ram memory sticks, power supplies etc). As far as it regards their functionality there’s no difference between the two types of servers, the difference is only in terms of space required inside the server farm.

Web Server (Software)

If we refer to a web server software we’re talking about that program that actually delivers the content of your website. This software waits for requests of web pages coming from the internet and, when such requests arrive, retrieves the page and pushes it to the browser from which it received the request the request.

This is the functioning in case of static websites, instead if the website is dynamic the web server software uses additional modules and functions to build the content to be delivered.
It is really easier to explain this with an example.

Let’s say we have a database of events with dates and cities, and one of the pages of our website is events.php, it is written in PHP and it’s used to display to the visitors the events based on their search settings: the visitor sends a request (submitting a form or clicking a link) searching for events in Miami on March 28, which will lead him to a URL like http://www.yourdomain.com/events.php?city=miami&month=03&day=28 (if you have no clue what this url means then read this article): the web server receives this request and executes the php instructions in the page events.php; this will retrieve the events in Miami on March 28 and format these events in HTML. When this part has been completed the server will send the just composed HTML document to the visitor’s browser.

The most widely used web server software are Apache on Unix/Linux based systems and Microsoft IIS on Windows systems.

Probably you have heard about the Amsterdam Red-Light District
as this is a very famous section in the Netherlands. Much to
your surprise, what you may have heard is true! Here are some
facts about the Amsterdam Red-Light District, a place unlike
any place else.

needs and desires of locals and visitors for five centuries, and

the tree-enshrouded canals that a certain charm tempts you
to linger longer in the area. In this district, music of every
genre can be heard along the streets from a dozen or more
places late at night. And, it is the classier restaurants,
redone streets, and revamped facades that transform what
once dark and dingy into one of the most attractive parts of
town – the Amsterdam Red-Light District.

trade. Much to your surprise, the prostitutes in the
Netherlands are also taxpayers. However, discrimination is
still very much part and parcel in this kind of trade as a
number of the prostitutes reported that some banks even
refuse to grant mortgages for instance.

Now, as a legal profession, the government ensures that all
prostitutes are able to access medical care and work in
better conditions by way of regulating and monitoring working
practices and standards. Also, it is worth noting that contrary
to the popular belief, the Amsterdam Red-Light District is
actually the safest area in the city as clusters of policemen
and private bodyguards employed by the girls themselves are
always on duty.

The Chinatown

The Amsterdam Red-Light District is one of the few places on
earthy where you can authentic and really tasty Chinese food.
The restaurants in this district are easy to find as cooked
Duck is typically hung in the front window. However, Chinatown

Indonesian and Thai restaurants and caf
