Unlimited Bandwidth Hosting–Believe it or Not to believe?

It seems to be pretty unavoidable and attractive to see unlimited web hosting packages on the websites of various web hosting providers.Most users get attracted to such promotions made by the web hosting companies in India. Now the question is to believe such offers to be true or simply discard it and look for a honest web hosting provider offering best web hosting services along with reliability and transparency.Most of the users get stuck up in such a dilemma between the two.

We often see hosting companies offering unlimited bandwidth hosting.There is a high level of competition among hosting companies, and each are trying to attract customers by offering various attractive offers at cheap prices. Unlimited bandwidth is one of the features often used by hosting companies to draw the attention of new potential customers. And due to the lack of knowledge,users often fall prey to such promotions and unfortunately sign up for such web hosting packages.They later realize the facts and hidden aspects of such services. Users are simply unaware of the fact that unlimited bandwidth hosting is practically impossible.

Hosting companies usually offer such unlimited bandwidth hosting packages to small companies and individuals who have their own websites. The web hosting service provider is damn sure that your website would never even come close to using the bandwidth.Rather most websites would actually not use much bandwidth at all. Though, if your site receives a lot of users, typically if you have a websites that allows live or offline audio or video streaming and multiple users using your website at the same time, a lot of bandwidth is being consumed,then what happens? ,terror strikes and something that you had never expected actually happens.Getting attracted to  the irresistible offer,you surely wouldn’t have had a look at the terms of service (TOS) of the web host before signing up with them. Somewhere, in small print in the terms of service agreement there will surely be an elaboration of the term “unlimited bandwidth” and what does that refer to,from the companies point of view.If you read carefully,you would be shocked to read the actual explanation of the term.Its then that you realize that there is definitely a limit on “unlimited bandwidth hosting” package too. Once you exceed a particular amount of bandwidth,your web hosting services are shutdown.After inquiring about the reason,you are asked to upgrade to a higher package,failing to do so would result in a suspension of the account.

Apart from such falsely committing web hosting companies, there are companies who market their services with promotions jargon’s such as “Unmetered Bandwidth hosting”. You can believe such companies.After paying an X amount for this option you are free to use bandwidth as much as you require.But,there involves a trick within it too.The rate of speed is reduced and you ultimately end up using the same bandwidth as that with a normal hosting package.

Therefore, it is advised to sign up for standard web hosting packages or if you have a website that receives heavy traffic then even a small business web hosting package too would be appropriate.Just in case in future you realize an increase in the number of visitors to your website, you may simply contact the hosting company and check out the plans that are available that best fulfills your requirements.

It is also better to know the current status of the approximate number of daily visitors to your website and the size and other requirements of your website.Let all these details be known to the best web hosting provider that you have shortlisted.Ask for their advice about the appropriate web hosting package suitable for your website to be hosted.This would avoid the suspension of your web hosting services and avoid the loss of revenue generated from your website.

Setting up a Cron job

If you have a site that is hosted on a server you might have experienced that there are certain types of commands or say scripts which have to be used/entered many times so that the program you want to run will run and work effectively.

As it is very important for these types of programs that you enter the commands or these programs will not work. There are some of the programs which require the same scripting every minute, hourly, daily, weekly or monthly so that they continue working. But, these scripts are not so short and easy to be entered every minute, hourly, daily, weekly or monthly and even if it is, it is not possible for anyone to do this task for 24×7×365 days a year.

For this, it is very important to have a system for this task so that the scripts which have to be entered in different time intervals are entered and the programs will run effectively.Cron job is a kind of software which is able to do this work for you. Cron job allows you to setup a schedule of the scripts and commands to be entered on your server so that you can run the desired task on the server at the appropriate time. For example, if you want your server to accept the emails only for a limited time then you can do this by entering the required commands only once and setup the cron job.

Once it is setup it will work according and your VPS hosting server will accept the emails only for the time you have specified. This means it is a kind of a software that will run a service on your server at the time you want it to be available. The cron job can be setup with the help of the following steps:-

There are two options by which you can setup the cron job one is the standard GUI and the other is the Advanced (Unix Style) option:-

IMPORTANT :- It is important that you understand how the cron jobs actually work.You need to have a good knowledge of Linux commands before you can use cron jobs effectively, especially when using the “Advanced (Unix Style).” Check your script with your hosting administrator before adding a cron job.
