How to Choose a Web Hosting Service for your Web Pages
There are thousands of web hosting services.How to Choose a Web Hosting Service for your Web Pages? With a good web hosting you don't have many problems; with a poor web hosting you have much pain. So how do you go about shopping?
1. Reliability and speed of access
Not only should the web hosting be reliable and fast, it should guarantee its uptime (the time when it is functional). Look for a minimum uptime of 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.
2. Disk space
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.
3. Traffic/Bandwidth(Data Transfer)
Data transfer ("traffic" or "bandwidth") is the amount of bytes transferred from your site to visitors when they browse your site. 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.
4. PHP, FTP, Perl CGI-BIN access, SSI, .htaccess, telnet, SSH, 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 CGI 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 customise 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 CGI scripts, maintaining databases, etc. Cron jobs may be needed for programs that you need to be run periodically (eg once a day). Check to see if these facilities are provided.
5. Technical support
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.
