How Many Servers Does A Web Hosting Server Need?

Web Hosting customers don’t always realize what goes on behind the scenes of their web hosting service. The layman often thinks that the web hosting service is just another software installed on a monster computer, bit of which are sold to the end user. But there’s a lot more that goes on behind setting up a web hosting service. While some hosts use separate machines to run services like email, FTP, HTTP etc., some hosts install all these services on a single machine. This article takes you into the web hosting world and shows you which software servers are running to give you the best web hosting experience with different services.

Web Server

The web server is one of the most important parts of your web hosting service. The web server is what actually delivers your web page to the user’s browser. It also handles different requests for information that your browser makes and also takes care of incorrect or erroneous requests. When you see 404 error pages or warning messages, these are all served up by the web server. Web hosts commonly use IIS, Apache, Nginx and Tomcat amongst many different web servers. Web servers use the HTTP protocol to communicate with the user’s browser. The administrator also has the capability of restricting folders, files and websites through the web server configuration.

Mail Server

The mail server is essential when providing email service. The mail server allows the sending and receiving of email on specific ports. The mail server helps filter the received mail to different users’ folders and thereby allows multiple domains to be hosted on a single physical machine. Mail servers are also capable of redirecting mail and applying conditional filters to weed out unwanted mail and fight spam. Most mail servers allow the use of third party plugins or software to aid them perform their functions. For example mail servers can intelligently use third party RBLs or black lists to identify if a mail sender is actually a source of spam which should be rejected before he can reach the mail server. Mail servers usually use IMAP, SMTP and POP3 protocols to serve their purpose.

FTP Server

Almost every web host offers FTP services to transfer files. But most users don’t realize that this requires an FTP server at the hosts end. An FTP server allows connections using the FTP protocol, for the transfer of files. This aids users in downloading or uploading files in simple, quick and efficient way. FTP servers control the bandwidth usage, user connections, authentication system and even file management for the user. FTP servers are inexpensive to maintain and are now considered as included in any web hosting package.

SQL Server

An SQL server is a database management server which allows users to create and store data in relational tables, using the Structured Query Language or SQL. On windows machines, Microsoft MS SQL is installed, whereas Unix based hosting systems usually come with open source alternatives like MySQL, Postgresql, MariaDB among others. Web hosts sell databases based on the package that the user takes. Each database requires CPU and memory resources to function properly. Databases form up the backbone of most websites which have a Content Management System or which store a large amount of data.

Others

Some web hosts offer their own DNS service, for which they need to run a DNS Server on their systems. The DNS server just maps the domain name to the servers IP address so that when a visitor is using a service on a website, he is served up the right information from the right source. Premium web hosts offer File Sharing services and have a Web DAV Server either separate or integrated into their Web Server (as above). This allows users to quickly sync files to and from their website onto their mobile devices. Almost all web hosts also provide an SSH service so that users can connect securely to different ports for different services on the account.

While web hosting may seem like an easy business, managing all these services can be quite a task, which web hosts need to do on a daily basis.

When Do We Need MySQL Databases With Our Web Hosting?

Leave a reply

Whenever you buy web hosting, your hosting provider is sure to include an option called “Databases” in his price quotation or package details. But not many of us know what are databases and why we need them when setting up a website. This article aims to explain a couple of reasons why we use databases and when we need them for our website.

The database systems we usually get with our web hosting accounts are all relational database systems or RDBMS. If we take a Windows hosting server we usually get Microsoft SQL aka MSSQL and if we take a Unix based system we usually get MySQL. Both these systems put your website data into tabular layouts for fast and easy retrieval.

Databases are a collection of rows and columns, where each row or column is related to the others in some way. Due to this relation, information from this database can be retrieved quickly and efficiently as compared to if the data was stored in any other unstructured format. You can consider a database as a collection of multiple spreadsheets which are all related to each other in some way or the other.

Security

A major advantage of having your data stored in a database is the ability to protect the database from unauthorized access, or the ability to protect a database record from being tampered with. A simple example would be the storage of login credentials. In a simple way, login credentials can be stored in a simple text file and be read by your script which does the authentication. However, your file will always save the password stored in plan text, making it vulnerable to anyone who has access to it. Databases have the ability to encrypt the entries using a hashing algorithm to obscure them. Further, to read or write to the database, you need to specify login details, something which is not easily possible with an ordinary text file or spreadsheet.

Efficiency

Due to the manner in which data is stored in the database, retrieval and storage is most efficient. Unlike a spreadsheet, where anything and everything can be stored in any cell, SQL restricts the type of information stored in each row or column based on certain conditions. This validation is inherent in the properties of SQL and is an added advantage for a programmer or developer. Due to the various inbuilt mechanisms that are present in RDBMS systems, they are the most preferred method of storage and retrieval of data.

An article on the DatabaseJournal Blog explains this in a lucid way:

“…The problem with text files is during a read, if the text file is large, it can take quite a bite of time to open and scan the contents of the file looking for what we want. Also, if we wanted to see all the sales to a specific customer, the entire text file would have to be read, and every line occurrence of the customer name would need to be saved in some temporary place until we had them all. If we saved to a spreadsheet instead of a text file, we would have a Sort feature built in. So we may be able to find all the sales to a specific customer quicker, but again, if the file was large, opening the spreadsheet could take a great deal of time.”

Administrative Control

Database systems also have various control mechanisms which allow easy administration of the database and tables within it. The most important part is user management. Each user can be given specific rights to the database, thereby allowing limitation in access so as to secure the data from being tampered, modified or altered. Database Administrator’s can tweak many settings of the database thereby restricting the flow of data, the connection speeds, maximum number of connections to the server and even adjust what hardware resources should be allocated for performing a task.

Buying Web Hosting Space From Your Web Designer? Watch Out

Leave a reply

We all love to shirk responsibility and hand over some of our problems for people who are willing to handle them. Buying the right type of web hosting maybe quite an overwhelming process for a not so tech savvy business owner. The task of how muck disk space, how much bandwidth and all the technical jargon involved can get quite taxing to understand. This is a primary reason why web designers are more than happy to bundle a web hosting account along with their designing fees. But there are many ways in which such relationships can get sour if the terms of the bundling are not made clear initially. This article explains what could go wrong if you buy web hosting space from your web designer rather than buying it independently.

Buying Web Hosting Space From Your Web Designer? Watch Out

Buying Web Hosting Space From Your Web Designer? Watch Out

Price

Although you may feel that you’ve got a great package deal on your web hosting along with design fees, you should be aware that web hosting fees are recurring fees and usually payable monthly or annually. Don’t get carried away with the waiver of fees for the first year. Some website owners are in for a rude shock when the next year on the renewal anniversary, they receive a huge invoice for renewal of the web hosting account. Design firms are almost always resellers or affiliates of web hosting companies and never a web host themselves. This can be a positive thing as well as a negative thing. Sometimes they may be able to offer you a highly competitive pricing, while some of them may just exploit your ignorance or inability.

Lock In

Taking a package from your website developers may lock you in to their web hosting package as well as their design. More than a physical barrier, it creates a sort of psychological block which prevents you from switching services or choosing a different design for your website. This is precisely the reason why low cost packages are offered and customers are lured to them. Website owners fear that if they shift the design services, then the developers may not be too cooperative and not give them control of the hosting account. Similarly, even if the hosting account has limited features or provides bad service, you may be willing to stick to it if it is bundled with your development package. You should always have control of your hosting account and also have your design source code with you.

Support

If your web designer is knowledgeable, well equipped and efficient, you may get good technical support. Issues related to your website’s hosting will be solved quickly. But if your designers are new to the hosting world, they may not be of much help. Sometimes it maybe helpful to buy the hosting and design from the same company, so that all your services are under one roof. This way there can be no blame game as to which service is deficient, in case of a failure. However, this can also be a disadvantage if you have hired a nascent design firm. They maybe too raw to know the intricacies of hosting and may not be able to keep up with changing technologies or may not be competent to provide the right security or optimization measures. This should not be expected from them either, as designing is their primary business and all other things are side businesses.

Control

If you are taking a package deal, make things clear at the beginning. What happens if you decide to hire the services of another designer? Who keeps the control of the website? On whose name is the domain name and hosting registered? How do you login to control your website files? These are some of the basic questions that you should ask when you are offered such a deal. You don’t want to end up having a disagreement with your web designer, who turns off your website and takes control of your domain name, leaving you high and dry.

Web Hosting And Net Neutrality In A Nutshell

Web Hosting And Net Neutrality In A Nutshell

Web Hosting And Net Neutrality In A Nutshell

Net Neutrality is a phrase which is being sprayed all over the internet without providing a simple and clear explanation to the layman. Web Hosts are as affected by Net Neutrality decisions just like any ordinary internet user. Many people are quick to point out that Web Hosts also practice data discrimination and should be placed on the same guillotine as ISPs. However, this is not the case as there is a huge difference in providing Bandwidth and in providing a web hosting service. This article points out a couple of reasons why the Web Hosting industry also embraces Net Neutrality with open arms and why a comparison maybe equal to apples and oranges.

Low Entry Barriers

Unlike Internet Services in any country, it is pretty simple for a person to start a web hosting business. To become an ISP, there are several legal and business hurdles that one must cross. It’s not an easy task and needs deep pockets and great influence to start the business. It is on par with a Telephone Company or Electricity Supplier. On the other hand, starting a web hosting business can be done with little or no investment. Web hosting resellers don’t even need to own a server or commit any sales to start their business. A small or medium host can spend a couple of dollars every month and lease a hosting server. This means that to enter into this industry the cost is very low and regulation is negligible. There is no Government control or paper work that needs to be done to sell hosting space. This automatically increases the number of players in the industry.

Intense Competition

The low entry barriers cause such intense competition, that the ultimate beneficiary is the end user. If one web host starts acting restrictive, people can easily switch to another one without much ado. Due to customer-facing side of the business being virtual and online, there is easy accessibility and no physical hindrances to switching. However in most places around the world, the number of ISPs are miniscule and in rural areas there may not even be more than one or two. This kills the competitiveness of the business and gives a dominant position to the ISP, which can be misused to exploit subscribers. Often, when there are only a couple of ISPs operating, it leads to a sort of cartel and price fixing which cannot be questioned. Anti-competition laws around the world prohibit such behavior and try to break up this dependence.

Cut-throat Pricing

Besides striving to offer the best service in terms of speed and resources, every web host aims to offer the best price too. The price-war is so aggressive that even customers find it hard to make a decision as they are spoilt for choice. This is exactly what ISPs don’t want. ISPs want to create restrictions among different website services or online facilities by throttling the popular ones and charging a premium for them.They may either recover the premium from the customers or may ask the web services to cough up that money. If a web host throttles traffic for a certain type of domain name and prioritizes traffic for one that he is selling Eg: .co domain names, then he will soon be out of business because all his clients will switch. As we have learnt from free online services, the consumer doesn’t like to be restricted. The more restrictions you place, the more they will shun your service.

Security and Convenience

Web Hosts do restrict certain type of traffic and also do some filtering, but this is not to create unfair competition or to get a dominant position advantage, but to ensure security and stability of their services. Eg: A host may limit simultaneous FTP connections from a single IP address to a maximum of 50. This is to prevent abuse of their FTP server and to ensure that other users on the same shared server are able to enjoy the service too. ISPs want to filter traffic to commercially exploit the end user, as they know that the end user has limited options for accessing the internet.

Are Cheap Domain Names For Real? Whats The Catch?

Are Cheap Domain Names For Real? Whats The Catch?

Where should you purchase a domain name from is purely your own decision. Although the differences in domain name management facilities are few across different providers, the pricing varies drastically. There are various factors (besides competition) which contribute to this disparity in pricing. Knowledge of these factors is important in influencing your decision in how to and from where to buy domain names. Savings can range from a few dollars to even $50 per domain name. This article explains why domain names are available at such a cheap price and why sometimes it maybe an illusion to fool the customer.

Addon Services

Many Domain Name providers offer the cheapest pricing because they provide only the basic rudimentary domain registration services. They do not provide any extra services and only allow minimalist domain management options. Domain Name Servers (DNS), Email Forwarding, Domain Forwarding, Free Landing Page, WHOIS Privacy and some other services are facilities which are charged extra. If your domain name provider is giving you these services for free along with cheap domain pricing, it is definitely worth it. But to maintain a slim margin and to undercut the competition, most domain registrars charge a hefty additional fee to provide these addons.

First Year Pricing

Most domain name providers offer a very cheap price for domain name registrations to lure new customers to their service. However, many providers mislead people into buying from them by displaying an extremely low price for registration. They do not mention what the price for renewals will be. Renewals are offered at the normal price which most providers offer, which will obviously be much higher than the price of the first year registration. Most customers do not read the fine print at the time of registration and follow the price carrot into the providers net. This is often a reason why customers are delighted at the time of registering the new domain but are frustrated the next year when realization dawns upon them. A transparent host will clearly indicate that the domain pricing will increase from the next year onwards, as the offer or pricing is only applicable on fresh registrations.

Reseller Discounts

Some websites offer cut-throat pricing for Domain Registrations, Renewals and even Transfers. This is possibly due to the fact that they themselves receive a heavy re-seller discount from domain registrars and are able to pass on the discount to their customers. Registrars do not usually sell domains to the end user in a big way. Their retail pricing is very high and discouraging for retail clients. The easiest way for them to get customers is to shift the burden of customer acquisition on the resellers. The incentive given to resellers is proportionate to the yearly commitments of the resellers. Hence if you try and compare a reseller’s price with the price of the same registrar, it will be like comparing apples and oranges i.e. they are uncomparable.

Bundled Pricing

Many hosting companies offer heavy discounts on domain name pricing if you bundle a domain name with their hosting packages. If you cease to keep their other products or services, your domain which is bundled with it will be renewed at their regular or standard pricing. The cost of the standard or regular pricing maybe much higher than the discounted pricing, but it is natural that the service providers who offer such discounts will obviously offer an incentive to promote their products or services. If you really need the bundled product, then it would be a good idea to take the package, but some clients often buy the bundle just because of the price illusion that they are getting the domain name free. This is not the case, especially due to the fact that the cost of the domain name has also been factored into the price of the bundle. Similarly it will offer a good perspective on how much the principal product should really cost.

Why Are Website Templates Preferred Over Custom Web Design?

Why Are Website Templates Preferred Over Custom Web Design?

Why Are Website Templates Preferred Over Custom Web Design?

Template based website systems are overtaking the requirement for a custom made personalized website. Even web designers are constantly finding ways in which to package their products and manufacture them in bulk. But what are the reasons for people buying template based websites and avoiding custom built websites? This articles aims to highlight the major factors which influence the purchase of a template based website design over a customized one.

Turn Around Time

The crux of setting up a new website is having it up and running quickly. The main objective is to put the website out and keep improving it. Most design firms take ages to put out the first version of a website. They have lengthy procedures and sometimes have long and cumbersome processes to be followed before any work can be made live. This often leads to delays and long timelines, which cause disinterest in the client and also demotivate the design team. This is remedied by ready made template based options which allow a certain level of customization to personalize the template for the clients business.

Seeing Is Believing

Just like ready made clothes, templates allow you to see a live working of the website and allow you to preview and simulate the website’s functioning before you actually purchase it. This means that you can see a fully functional sample website with dummy text and images and actually visualize how it would suit your website design. While tailor-made clothes will definitely fit you better, there is always a time-lag and also a risk of the tailor getting it wrong.

Cheaper

A ready made website will definitely work out cheaper than a custom made one, especially due to its re-usability and lack of personal touch. This maybe very crucial for a business which is newly launched and wants to atleast have a placeholder website to show to customers. This is also a crucial factor in determining the long term goal of the website and how you would like to keep evolving your online strategy.

Independence

A very major factor in deciding your design option is whom you are dealing with. Many designers consider themselves to be at par with Picasso and Michelangelo. This means that you may have a tough time in getting them to do things in a time-bound or disciplined way. Almost all design firms that we have dealt with have overshot their promised timeline and taken more than double the time to do the work correctly. While a bit of creativity should be left to the discretion of the design studio, it should also be clearly agreed that time is of essence and that a delay in work can be costly. Some businesses have taken years on end just to get the first glimpse of their website live. By that time their funds were drained and they had lost a considerable amount of revenue from online sources. On the other hand, templates allow you to go to any designer or coder to alter the design. Some websites even offer their own customization service. The bottom line being that your design source is with you and you are not locked into the services of a particular firm of developers.

Customization

Although a template can hardly be tweaked to suit your corporate branding, you can make a lot of changes to make it look more personalized. Just like you can get a ready-made shirt altered to suit your size, you can get a ready website also tweaked and twisted to give it a better look. It may look clumsy and a bit out of place, it may even look very cliche and standard, but for the price it is definitely a good deal.
