Guideline to choose Web Hosting Service
Posted by Hari Saryono on 1 April 2009
What are some of the things you should look for when choosing a web host? The criteria for choosing a free web host and a commercial web hosting solution are slightly different although they do overlap. If you are only interested in one of these types, you can simply skip to the appropriate section. I have written these sections to be as independant of the other as possible.
Choosing a Free Web Host
Most free web hosts impose advertising on your website. This is done to cover the costs of providing your site the free web space and associated services. Some hosts require you to place a banner on your pages, others display a window that pops up everytime a page on your site loads, while still others impose an advertising frame on your site. There is really no hard and fast rule which is to be preferred: some people hate a pop-up window, other webmasters dislike having to stuff banner codes onto their pages, and many people cannot stand an advertising frame (which may cause problems when you submit your website to search engines). Whichever method is used, check that you’re comfortable with the method.
Note that free web hosts without forced advertisements aren’t necessarily good news. Without a viable means to recover the costs of running their server, many of them close with alarming frequency.
Amount of web space
Does it have enough space for your needs? If you envisage that you will expand your site eventually, you might want to cater for future expansion. Most sites use less than 5MB of web space. Actually 5 MB is huge enough for a personal website. Your needs will vary, depending on how many pictures your pages use, whether you need sound files, video clips, etc.
Some free hosting providers only allow you to design your page with their online builder. While this is useful for beginners, do you have the option to expand later when you become experienced and their online page builder does not have the facility you need? FTP access, or at the very least, the ability to upload your pages by email or browser, is needed. Personally, many people feel FTP access is mandatory, except for the most trivial site.
File type and size limitations
Some free hosts impose a maximum size on each of the files you upload (including one with a low of 200KB). Other sites restrict the file types you can upload to HTML and GIF/JPG files. If your needs are different, e.g, if you want to distribute your own programs on your pages, you will have to look elsewhere.
Reliability and speed of access
This is extremely important. A site that is frequently down will lose a lot of visitors. If someone finds your site on the search engine, and he tries to access it but find that it is down, he’ll simply go down the list to find another site. Slow access is also very frustrating for visitors (and for you too, when you upload your site). How do you know if a host is reliable or fast? If you can’t get feedback from anyone, one way is to try it out yourself over a period of time, both during peak as well as non-peak hours. After all, it is free, so you can always experiment with it.
Perl and PHP
This is not particularly crucial nowadays for a free web host, since there are so many free script hosting services available that provide counters, search engines, forms, polls, mailing lists, etc, without requiring you to dabble with Perl or PHP scripts.
However if you really want to do it yourself, with the minimum of advertising banners from these free providers, you will need either PHP or Perl access. Note that it is not enough to know they provide PHP or Perl access: you need to know the kind of environment your scripts run under: is it so restrictive that they are of no earthly use? For PHP scripts, does your web host allow you to use the mail() function? For Perl scripts, do you have access to sendmail or its workalike?
Nowadays, many free web hosts impose a limit on the amount of traffic your website can use per day and per month. This means that if the pages (and graphic images) on your site is loaded by visitors beyond a certain number of times per day (or per month), the web host will disable your web site (or perhaps send you a bill). It is difficult to recommend a specific minimum amount of bandwidth, since it depends on how you design your site, your target audience, and the number of visitors you’re able to attract to your site. In general, 100MB traffic per month is too little for anything other than your personal home page and 1-3GB traffic per month is usually adequate for a simple site just starting out. Your mileage, however, will vary.
Choosing a Commercial Web Host
Reliability and speed of access
Not only should the web host be reliable and fast, it should guarantee its uptime (the time when it is functional). Look for a minimum uptime of 99%. In fact, even 99% is actually too low – it really should be 99.5% or higher. The host should provide some sort of refund (eg prorated refund or discount) if it falls below that figure. Note though that guarantees are often hard to enforce from your end – the host usually requires all sorts of documentation. However, without that guarantee, the web host will have little incentive to ensure that its servers are running all the time.
Data Transfer (Traffic/Bandwidth)
Data transfer (sometimes loosely referred to as "traffic" or "bandwidth") is the amount of bytes transferred from your site to visitors when they browse your site.
Don’t believe any commercial web host that advertises "unlimited bandwidth". The host has to pay for the bandwidth, and if you consume a lot of it, they will not silently bear your costs. Many high bandwidth websites have found this out the hard way when they suddenly receive an exhorbitant bill for having "exceeded" the "unlimited bandwidth". Always look for details on how much traffic the package allows. I personally always stay clear of any host that advertises "unlimited transfer", even if the exact amount is specified somewhere else (sometimes buried in their policy statements). Usually you will find that they redefine "unlimited" to be limited in some way.
In addition, while bandwidth provided is something you should always check, do not be unduly swayed by promises of incredibly huge amounts of bandwidth. Chances are that your website will never be able to use that amount because it will hit other limits, namely resource limits.
To give you a rough idea of the typical traffic requirements of a website, most new sites that are not software archives or the like use less than 3 GB of bandwidth per month. Your traffic requirements will grow over time, as your site becomes more well-known (and well-linked), so you will need to also check their policy for overages: is there a published charge per GB over the allowed bandwidth? Is the charge made according to actual usage or are you expected to pre-pay for a potential overage? It is better not to go for hosts that expect you to prepay for overages, since it is very hard to forsee when your site will exceed its bandwidth and by how much.
For the same reason as bandwidth, watch out also for those "unlimited disk space" schemes. Most sites need less than 10 MB of web space, so even if you are provided with a host that tempts you with 200 MB or 500 MB (or "unlimited space"), be aware that you are unlikely to use that space, so don’t let the 500 MB space be too big a factor in your consideration when comparing with other web hosts. The hosting company is also aware of that, which is why they feel free to offer you that as a means of enticing you to host there. As a rough gauge, thefreecountry.com, which had about 150 pages when this article was first written, used less than 5 MB for its pages and associated files.
Does its technical support function 24 hours a day, 7 days a week (often abbreviated 24/7), all year around? Note that I will not accept a host which does not have staff working on weekends or public holidays. You will be surprised at how often things go wrong at the most inconvenient of times. Incidentally, just because a host advertises that it has 24/7 support does not necessarily mean that it really has that kind of support. Test them out by emailing at midnight and on Saturday nights, Sunday mornings, etc. Check out how long they take to respond. Besides speed of responses, check to see if they are technically competent. You wouldn’t want to sign up for a host that is run by a bunch of salesmen who only know how to sell and not fix problems.
FTP, PHP, Perl, SSI, .htaccess, telnet, SSH, MySQL, crontabs
If you are paying for a site, you really should make sure you have all of these.
Note that some commercial hosts do not allow you to install PHP or Perl scripts without their approval. This is not desirable since it means that you have to wait for them before you can implement a feature on your site. ".htaccess" is needed if you are to do things like customize your error pages (pages that display when, say, a user requests for a non-existent page on your site) or to protect your site in various ways (such as to prevent bandwidth theft and hotlinking, etc).
Telnet or SSH access is useful for certain things, including testing certain scripts (programs), maintaining databases, etc. MySQL is needed if you want to run a blog or a content management system. Cron is a type of program scheduler that lets you run programs at certain times of the day (eg, once a day). Check to see if these facilities are provided.
SSL (secure server), Shopping Cart
If you are planning on doing any sort of business through your website, you might want to look out to see if the host provides these facilities. These facilities normally involve a higher priced package or additional charges. The main thing is to check to see if they are available at all before you commit to the host. You will definitely need SSL if you want to collect credit card payments on your site.
Email, Autoresponders, POP3, Mail Forwarding
If you have your own site, you would probably want to have email addresses at your own domain, like email@example.com, etc. Does the host provide this with the package? Does it allow you to have a catch-all email account that causes any email address at your domain to be routed to you? Can you set an email address to automatically reply to the sender with a preset message (called an autoresponder)? Can you retrieve your mail with your email software? Can it be automatically forwarded to your current email address?
This is called various names by different hosts, but essentially, they all allow you to manage different aspects of your web account yourself. Typically, and at the very minimum, it should allow you to do things like add, delete, and manage your email addresses, and change passwords for your account. I would not go for a host where I have to go through their technical support each time I want to change a password or add/delete an email account. Such chores are common maintenance chores that every webmaster performs time and time again, and it would be a great hassle if you had to wait for their technical support to make the changes for you.
Multiple Domain Hosting and Subdomains
For those who are thinking of selling web space or having multiple domains or subdomains hosted in your account, you should look to see if they provide this, and the amount extra that they charge for this (whether it is a one-time or monthly charge, etc).
Is the type of operating system and server important? Whether you think so or not on the theoretical level, there are a few practical reasons for looking out for the type of server.
In general, if you want to use things like write/use ASP programs, you have no choice but to look for a Windows server.
Otherwise my preference is to sign up for accounts using the often cheaper, more stable and feature-laden Unix systems running the Apache server. In fact, if dynamically generated pages that can access databases (etc) is what you want, you can always use the more portable (and popular) PHP instead of tying yourself down to ASP. Another reason to prefer Unix-based web hosts (which include web hosts using systems like Linux, FreeBSD, OpenBSD, Solaris, etc) using the Apache web server is that these servers allow you to configure a lot of facilities that you typically need on your site (error pages, protecting your images, blocking email harvesters, blocking IP addresses, etc) without having to ask your web host to implement them. Knowledge about configuring Apache servers is also widely available.
I was actually hesitant to list this, but I guess it’s futile not to. However, I would caution that while price is always a factor, you should realise that you often get what you pay for, although it’s not necessarily true that the most expensive hosts are the best.
Monthly/Quarterly/Annual Payment Plans
Most web hosts allow you to select an annual payment plan that gives you a cheaper rate than if you were to pay monthly. My current personal preference is to pay monthly with all new web hosts until I’m assured of their reliability and honesty. Paying monthly allows me to switch web hosts quickly when I find that the current host does not meet my requirements: this way, I’m not tied down to a bad web host because I have prepaid for an entire year. I do this even if the new web host guarantees that they will refund the balance if I’m dissatisfied, since at the point I sign up, I have no assurance that they will honour their guarantee. Later (usually after many months or even more than a year), when I’m satisfied with the host, I often change payment plans to the discounted annual plans.
Not all hosting companies own or lease their own web servers. Some of them are actually resellers for some other hosting company. The disadvantage of using a reseller is the possibility that you are dealing with people who don’t know much about the system they are selling and who take longer to help you (they have to transmit your technical support request to the actual hosting company for it to be acted upon). However, this also depends on both the reseller and the underlying hosting company. It is thus wise not to rule out all resellers; there are a number of reliable and fast ones who are actually quite good and cheap. In fact, a number of resellers sell the same packages cheaper than their original hosting company. If you find out that a particular company is a reseller, you will need to investigate both the reseller and the real hosting company.
If you don’t stay in the USA, you have the option of hosting your site with some local provider. The advantage here is the ease of dealing with them (they are after all easily accessible by phone
call or a visit), your familiarity with the local laws and easy recourse to those laws should it be necessary. It should be your choice if your target audience is local (eg a local fast food delivery service). On the other hand, hosting it in USA has the advantage of faster access for what is probably the largest number of your overseas visitors (particularly if you have an English-speaking audience). You also have a large number of hosting companies to choose from, and as a result, cheaper prices too.
The Myth of the Perfect Commercial Host
In general, I doubt that there are any "perfect" web hosting companies around. Note that even if you are prepared to pay a huge price for your hosting needs, it does not guarantee that your host is any good. This is an interesting industry where a high price does not necessarily yield quality hosting and support.
On the other hand, one thing you can probably be sure of is that you will not get top-notched support if you only pay (say) $5 a month. At that price, which company can afford to hire enough good help to cater to all its users?
Like me, you’ll probably end up settling for a trade-off between price, reliability and features that you’re willing to live with.
