Comparative analysis of free web hosting servers

May 27th, 2008 by Samuel Becks

As we know, there are hosting fee (from $ 85 per year), a come free. True, absolutely nothing free in this life do not exist, except in cheese in trap for mouse, and free hosting company - clear proof. The services they provide are not free, but rather on barter: first you place on a host your website and then host your site available on their (or others’) advertising. Advertising, incidentally, may be different, and so it will have to go.

Here and think afterwards: normal pay for hosting (without others’ advertisements, “but” and “if” but only “and” i “or”) .

Immediately, even before deepening into details, should notice the following things:

a) free hosting absolutely not suitable for a solid and serious projects - sites of large firms, prominent social organizations, government agencies - only a dns (ie domain address), even without the other “beauty” free host can seriously damage the image of your company and you personally - as a web designer;

b) free hosting is ideal for large-scale non-profit web projects: to find somewhere sponsor, who will pay for 100 megabytes and more highly paid host problematic, while the same space on the second-hosting and you really will cost nothing.

In addition to paid and free hosting service, there is a third option - conditionally free hosting: many providers, making Internet access (dial-up or leased line) offer its clients e-mail and absolutely free hosting (even without advertising). Tempting offer, but get to this fishing rod should not be - too great likelihood that more or less distant future you want to change provider. And - forgive-proschaj favorite site, or at least, dns, in which you plug was invested so much effort … By the way, and it was good DNS - based on domain known local provider.

So, you’ve decided - you need it FREE hosting (although the fee is usually better). What are the same requirements must be offered for free hosting, and how to determine what you need? Basic requirements are:

A. The speed server

B. The restrictions imposed on the type and size of files posted

B. Place to be allowed under your site

The availability of SSI G.

D. Ability to launch CGI and PHP scripts

E. Not too much of advertising

Registrators of domain names

April 29th, 2008 by Samuel Becks

Let us consider the scheme of “possession” of domains in order.

Registrators of domain namesChief coordinator of the Internet, distribution and administration involved in IP-addresses, domains and backward domains, is a nonprofit organization IANA (Internet Assigned Numbers Authority, the Agency to provide the names and unique parameters protocols Internet). The structure of Internet governance - hierarchical, therefore, not difficult to guess that a tree at the second level are the regional coordinators. These coordinators to date recorded four, and they called Regional Internet Registries (RIR). Among them are ours, the European Organization RIPE NCC (Reseaux IP Europeens Network Coordination Centre, the European Network Coordinating Center). In fact, it not only European, because it deals with the distribution of IP-addresses and domains in the territory that includes Europe, Middle East, Central Asia and African countries in the northern hemisphere. A total of jurisdiction RIPE NCC is coordinating domains and IP-addresses one hundred and nine States. If you are interested in learning more about the regional distribution and the history of these organizations, visit a special section on the site RIPE NCC. At the same site you can see, as coordinator belongs to one country or another.

It is not difficult to see that domain registration services in Beijing offers many more organizations. Among them - secondary recorders, hosting, Internet Service Providers. All of them use the services of one of the official registrars. It is no secret, and not bad as someone may seem. What we generally received when the market has reached a large number of registrars? We should note that most of them offer registration of domain registrars on prices, and many and below. But most importantly, the emergence of many registrars, we have received high-quality service. Now we can not sit on a complex multi-application for registration of domain and poschelkat keys in the web interface and, after registering a domain name and still manage to get a convenient interface. Also, many registrars free prescribe your domain in their name-servers.

Who is to choose among a large diversity of registrators? There are a few tips. If you already have a quality hosting, which you’re happy and who are not going to change, it is logical it would be to shift the care of registration, domain support and linking it with your site for hosting. The more so that most hoster provide such services.

The second option - if you have a leased line from a good provider, you have your own Web server, but you are not satisfied with third-level domain, normally provided by the Internet provider. Then logically would like to register your domain provider. He will make the necessary settings, and pay for a domain name through the Internet service provider you might need, that is as you usually pay for Internet access.

And the last option (it can also be the first:) - apply directly to primary or secondary registrar of domain names. Many firms that specialize in providing specific services like “interception domains”, will also help choose a name for your domain. - In general, all options are good - choose to taste. The main thing is that you are satisfied with the proposed level of services. And if many features, you can always choose the best registrar. At least, from your point of view.

Domain Names: Introduction

April 22nd, 2008 by Samuel Becks

In short, the domain name is a “facade” - call (sequence of words), which enters users in the address bar browsers to visit your site, but which is not a valid address of your site on the Web. Domain names are linked to servers Domain Name Assignment System (DNS), which are used to translate digital addresses (known as IP addresses, or Internet Protocol addresses) in the word. Every site you visit on the Net, except his name is still and digital IP address, which is addressed by this site on the Internet.

Domain Names, .com, .net, .org

Total (generic) Top-Level Domains

Typically, domain names are classified according to their extensions, which represent a domain name identification codes. The three most popular types of Higher Level Domains (TLDs) - This domains, which are not tied to any country:

. COM: Short from. commercial, which means “commercial”. Domain names with the extension. Com on its popularity far exceeds other names and can be purchased by any person or company.

. NET: Short from. network, which translates as “network”. Originally, this domain was created to expand technical websites. But with the expansion of domains can be registered at will.

. ORG: Short from. organization, which means “organization”. Initially, it is intended for non-profit organizations and other organizations that do not use expansion. Com or. Net. Currently, a domain name with the extension. Org can be filed by any person or company.
Domains countries

Domain names can be assigned to the use of country-specific extensions
. Each country has its own domain extension; Canada, for example, uses the extension. Ca, Japan -. Jp and Russia -. Ru. In most countries there are special rules, which describe exactly who can register domain names using this extension, and for what purpose, it is therefore important to examine the object before anything done.
Alternative domain names

ICANN, the organization responsible for the administration of top-level domains across the globe, has recently approved several new extensions, which are not assigned any specific country. Among them:

. aero
. biz
. coop
. info
. mobi
. museum
. name
. pro

Each extension has been created for use for certain purposes and is accompanied by certain restrictions. More detailed information on these top-level domains, you can find at: http://www.icann.org/tlds/
Other domains expand

In searching for a suitable domain name, you can find sites that claim to use such as the expansion. Xxx,. Free and. Mp3. This is not a real expansion and they are approved by ICANN, rather, their availability is guaranteed for the user software. Because ICANN is not approved is not one of these extensions and, in addition, users who do not have the appropriate software, can not gain access to sites with names, the data expansion should only be used for some secondary goals.

While expansion. Com,. Net and. Org usually all on hearsay and the mind are not the only expansion that are available for use. From a functional point of view domains countries work as well as any top-level domain, and the expansion of alternative work not worse. Therefore, do not use the top-level domain mediocrity when you can find better with another extension.

Uptime is important

April 5th, 2008 by Samuel Becks

Let’s just call “uptime”. The word comes from the English uptime and liberal understandable to the masses, means “uninterrupted work time.”

At the moment, the situation with the quality of services in terms of sustainability, quite understandable. Ono, quality, more or less equally to all carriers and nearly the size of the host. 100% machine, or real work 24 hours a day throughout the year and may not provide any. This axiom, who would not say that. Because people are people, and technology equipment. Both are sick and broken, respectively. Another problem is that if your host organization, rather than individuals, the risk that the burn, say, the hard drive, and the money is not there, reduced to zero.

True, it is necessary to note that there are breakage, which within 5 minutes will not solve anybody, especially (the case of life), if the power supply burns redurantny of intelovskogo corps on Friday at 19.00. This in a shop around the corner is not to buy. And lucky us, if there is an emergency chassis (chassis - so, roughly speaking, a set of motherboard with the case and necessary “stuffing”), all finished in a couple of hours of downtime movement of hard disks subject to a working machine. As it was with us.

Pay attention to the statement - “we had six months of 100% uptime” is not worth it. Yes, it can be so if host silent that it is only half a year and clients has 20 members. In such circumstances, provide high quality services, in general, it is not a problem. Another situation of the mid-level managers (from 500 clients and above), and even more for large. Here, too, many trusted “puzomerkam” is not hurt. Admission is straightforward (the utriruem): 10 servers available to the public we have a monitoring server, which works only provider’s site and get 100% uptime. And what we have on client servers uptime below 95%, this is not a tragedy. You, as the customer, know about it only later.

What is Web Hosting?

April 5th, 2008 by Samuel Becks

If you want to participate in the Internet as a business information resource directory, or as a hobbyist wants to share data, information and knowledge with many people and communities on the Internet, you should include this in a central location on the Internet. You have to own a piece of space in cyberspace.

Web Hosting gives you and anyone with a computer and Internet connection to own a piece of cyberspace. In your space, you can get news, newsletters, documents, data files (web site), and its own post office (mail server) to accept mail, all in the context of you or your business. This is your space and to get a place, you either have to own a piece of Internet with the physical network connection to the Internet and computer spine (s) to act as the server (s), offering access to your files and post office, to people on the Internet to view your web site or send and receive e-mail with you.

Cost of ownership of a direct connection to the backbone and server dedicated to the web site and e-mail is out of reach for the average business, and especially members of the general Internet. Even the launch site and mail server on your computer when it is connected to the Internet requires a lot of technical capabilities and knowledge. Internet itself has to be your business for any of these options will be viable.

For every person in a business or a career in most industries today, it is essential to have a place in cyberspace, not just to be competitive, but to survive. Web-hosting companies were born out of this great need to ensure favourable conditions for the masses to own a piece of cyberspace to invite environment where people could have their piece of cyberspace on the Internet 24 / 7 without significant costs. Web-hosting companies have developed a model where they could split the areas of the servers are connected to the backbone and the “rent” of this space, a cost reduction in many people sharing the server and connection to the Internet backbone.

Obtaining place in the web hosting environment, you become a member and agree to the terms of the lease space - as if you were to rent a house or commercial premises for your business. If you agree, and to become a member, you granted access code, a key, to your piece of cyberspace. This is the key in the form of ID and password, allows you to connect to the web server and load up (transfer) your website so that it can be found on the Internet. Your username and password are also used to connect to a mail server to create and administer mailboxes to send and receive e-mail for you, your employees or family members. Just like when you rent a house or commercial premises for your business, you have so many rooms, bathrooms and space for use. In web hosting environment, your area identified as disk space and network transmission.

Disk space is measured in megabytes (MB) or gigabytes (GB). Megabytes roughly means 1024000 characters and Gigabyte to about 1024 million characters. Imagine, as one of the keys to the key board. These amounts determine how many files, documents or data, you can have your own web site.

The network transfer is also measured in megabytes or gigabytes, which determines how much data (number of files, documents or data) can be downloaded (transferred) people access to the web site. The more people, or more data, everyone gets access to the site’s data is transmitted over the network. The more disk space and transmission network you use a larger share of web hosting environment you use - therefore, the higher the rent.

Just as no office building, and the house is the same, not all web-hosting environment. Some offices downstairs, the other elevators, some ensuites homes, swimming pools and gardens - and others do not. Web-hosting environment as well, some propose to do just given birth patterns, and other bases offer a wide range of functions and facilities to help you do just anything you could ever need or want. Some features, and objects can be offered are the ranges for the use of the software, components, databases and server script processing.

Hosting is your space to cyberspace and it is imperative to have a place in cyberspace in our modern society, just as it is to have an office to do business.
