Web services use something known as SOAP (Simple Object Access Protocol) for sending the XML data between applications. The data is sent over normal HTTP. The data which is sent from the web service to the application is called a SOAP message. The SOAP message is nothing but an XML document. Since the document is written in XML, the client application calling the web service can be written in any programming language.
- The message parameter in the WSDL definition is used to define the different data elements for each operation performed by the web service. So in the example above, we have 2 messages which can be exchanged between the web service and the client application, one is the "TutorialRequest", and the other is the "TutorialResponse" operation. The TutorialRequest contains an element called "TutorialID" which is of the type string. Similarly, the TutorialResponse operation contains an element called "TutorialName" which is also a type string.
Our web hosting plans are designed for Canadian small businesses and entrepreneurs wishing to build, grow, and publish their website quickly and efficiently without breaking the bank, and include great tools such as Site Builders, WordPress, email, visitor statistics, and more. They are easy enough to use even if you have no technical experience, while being powerful and versatile enough to meet the needs of advanced software developers and power users.
The Internet Corporation for Assigned Names and Numbers (ICANN) is the organization that governs the rules and regulations for domain name registrations. ICANN requires, for various reasons including to determine ownership of a domain should a dispute transpire, that a publicly accessible database be maintained that contains the contact information of all domain registrants. In layman's terms this means your domain name will be searchable by anyone and those search results will include your full name, physical address and other contact information. In order to protect your privacy in this regard, Domain.com offers WHOIS Domain Privacy which then masks your information using our own and implements a procedure for you to control who is able to then gain access to your contact information via a WHOIS search. Whenever you buy a domain name, no matter what domain name registration service you use, you are subject to the same ICANN rules, for this reason it is important to use a reputable service who cares about your privacy. Domain.com always recommends enabling WHOIS Domain Privacy.
Web services are a key component in "mashups". Mashups are when information from many websites is automatically aggregated into a new and useful service. For example, there are sites that aggregate Google Maps with information about police reports to give you a graphical representation of crime in your area. Another type of mashup would be to take real stock data provided by another site and combine it with a fake trading application to create a stock-market "game". 

Web services are almost like normal a web page. The difference is that they are formatted to make it very easy for a program to pull data from the page, to the point of probably not using any HTML. They generally also are more reliable as to the consistency of the format, may use a different formal process to define the content such soap or raw xml, and there is often also a descriptor document that formally defines the structure for the data.
The company also offers higher-end Windows and Linux servers, available with Plesk and cPanel respectively. We were very intrigued to see that the company offers low-end Atom-based dedicated servers as well as the more traditional Xeon-based machines. One great resource for those doing some basic experimentation, or site development, is that it has a free, three-month trial for one of its lightly equipped Atom servers.
SOAP is known as a transport-independent messaging protocol. SOAP is based on transferring XML data as SOAP Messages. Each message has something which is known as an XML document. Only the structure of the XML document follows a specific pattern, but not the content. The best part of Web services and SOAP is that its all sent via HTTP, which is the standard web protocol.
A web hosting account is a secure space on powerful computers (called servers) located in special buildings (datacenters) that provide consistently fast Internet connections, redundant power supply, and physical access security. Today, web hosting has evolved from being considered “just some space on a server” to being a comprehensive platform on which you can build, publish, and market your website, in addition to providing powerful collaboration tools such as email, calendars, and file sharing.
HostGator gained points for uptime monitoring and regular backups, along with free cPanel or Plesk. We liked that SSH is available for the more technically inclined site operators and that dedicated IP addresses could be purchased. We did take points off because it's sometimes difficult to tell what the price is once promotional plans run their course. That said, with a generous 45-day money back guarantee, there's a hosting solution for almost everyone at HostGator.
You can find out if a domain name is available by searching at the top of this page. If the domain name you want is not available, try selecting a suggested alternative that appears or searching again. If you’re still stuck, our free guide, Bringing your business online: How to choose a domain name and more, provides some more in-depth information about domain names and helps guide you through the process.
If you aim to have a web presence, you've got to have email. It's a convenient way for potential customers and clients to send you a message, Word document, or other files. Thankfully, most web hosts include email in the price of their hosting plans. Some web hosts offer unlimited email account creation (which is great for future growth), while others offer a finite amount. You, naturally, should want unlimited email.
The first thing that caught our eye about Complete Internet Hosting was a great answer to my biggest complaint about hosting providers. Most hosting providers will suck you in with a relatively aggressive starting price, but when it comes time to renew, the renewal price can be two or three times the original price. I've even found one company that renews at more than six times the original price.
But, again, operationally it's quite strong. 24/7/365 customer support is available not only by live chat and email, but by phone. It offers free site migrations with some dedicated attention paid to making a transfer as smooth as possible. And, if you're willing to go for one of the higher-end plans, the company has put some serious attention into performance and caching.
If you've ever been worried about the tremendous amount of power large data centers consume, you might want to sign up with Green Geeks. The "green" in the company's name reflects the Green Geeks' commitment to the environment. It purchases three times the energy it actually uses in wind energy credits, essentially putting energy back into the economy. The company does this through a form of renewable energy certificates, which, while a bit complicated, means that it's not just energy neutral, i's actually helping fuel the green energy economy.
Without prejudice to other definitions I would say that a web service is software system that allows for inter-operable machine-to-machine / application-to-application interaction over a network. This generic definitions would also help consider REST architectures to be a web service as they provide similar functionality albeit being an architectural style unlike the SOAP which is a fully defined protocol.
We liked how Web Hosting Hub describes its new customer process. It tells new customers, "We walk you through setting up your account in a personal on-boarding call." The company has a few other wins as well. It offers an all-SSD infrastructure, automatic vulnerability patches and a custom firewall, SSH access for certain plans, free site migration and an excellent 90-day money-back guarantee. 
Once you decide you price range, you need to consider how long you'll need web hosting. If it's a short-term project—say, less than a month or two—you can typically receive a refund should you cancel your hosting within 60 days. Some companies offer 30-day money-back guarantees, others offer 90-day money-back guarantees. Once again, it's beneficial to do your homework.
That said, not all web hosts offer email. WP Engine, for example, does not. In such instances, you must email accounts from a company other than your web host. GoDaddy, for instance, sells email packages starting at $3.49 per user, per month. That might sound like a hassle, and just one more thing to keep track of, but there are actually some webmasters who feel that separating your email hosting and web hosting services is smart. That way, one provider going offline won't completely bork your business.
Rounding out the wins, InMotion offers a full 90-day money-back guarantee. On top of that, here's a special money-saving hint. In a chat session confirming pricing and offerings, the operator offered me some special prices and deals that reduced the published price by a few bucks. I was also told that while promotional pricing does go up at the end of the offer period, if you contact customer service, InMotion has a "loyal customer discount" that may bring the price back down.
A Content Distribution Network (CDN) is a network of servers distributed geographically. The purpose of a CDN is to deliver content on the internet much faster. If a user in Toronto is trying to access your website, the closest server to them will take care of this. But someone coming to your website from Sydney, Australia, will be catered to by a server closest to them. The main host server holds your website content, and all the other servers have a cached version each.
Registration of a domain does not automatically imply the provision of DNS services for the registered domain. Most registrars do offer DNS hosting as an optional free service for domains registered through them. If DNS services are not offered, or the end-user opts out, the end-user is responsible for procuring or self-hosting DNS services. Without DNS services for the domain, the registration is essentially useless for Internet services, although this situation is often encountered with domain parking and cybersquatting.
Before the development of image hosting services, the display and exchange of images on the early public Internet of the 1980s-1990s was a laborious and complex process. Expertise was needed to set up a private file server, to connect it to the Internet, and paying for the potentially expensive dedicated Internet connection. Some experts would provide access to a Unix shell and some file storage, via paid access, free public access, or just made available to a select group of private friends. Uploading of images was accomplished with command-line tools like FTP, or uploading images using slow 14.4 to 33.6 kilobit dialup modem connections and terminal protocols like XMODEM to the server storage.
It is unwise to attempt to transfer a domain immediately before it expires. In some cases, a transfer can take up to 14 days, meaning that the transfer may not complete before the registration expires. This could result in loss of the domain name registration and failure of the transfer. To avoid this, end users should either transfer well before the expiration date, or renew the registration before attempting the transfer.[4]
If you require a lot of functionality and versatility from your website, you’ll benefit from programs and applications that can help you build your site. Our Web hosting plans give you access to free, server-side applications that can be used to develop and customize your website, including popular Content Management System (CMS) applications like WordPress® and Joomla!®. You can even add a Dedicated IP if you plan to add an SSL Certificate later.
HostGator gained points for uptime monitoring and regular backups, along with free cPanel or Plesk.

A directory called UDDI (Universal Description, Discovery, and Integration) defines which software system should be contacted for which type of data. So when one software system needs one particular report/data, it would go to the UDDI and find out which other systems it can contact for receiving that data. Once the software system finds out which other systems it should contact, it would then contact that system using a special protocol called SOAP (Simple Object Access Protocol). The service provider system would first validate the data request by referring to the WSDL file, and then process the request and send the data under the SOAP protocol.
