the 'glue' that makes a database-driven website do what it should. However, the two languages, are very different: Perl is powerful but hard to read, while PHP is simpler but more limited. Choosing between them is largely a matter of preference, which is why they're both included in the system – some people also include a third P, Python, as an alternative language. If you're starting out, it's probably best to use PHP – the official site at php.net has good tutorials and references on the language. Perl's site is at www.perl.org, but you should only really start with Perl if you've got some previous programming experie Getting LAMP. If you want to get the whole LAMP system together instead of downloading the components separately, a good place to go is www.apachefriends.org/en. They offer it for download – don't worry, all the software is free. You don't get Linux, but you get everything else, and it will install easily on most operating systems, including Linux and Windows. LAMP Variants. There are a number of LAMP variants that replace parts of the system. While these systems aren't as popular, they're still worth knowing about and considering. WAMP: Windows replaces Linux. MAMP: Mac OS replaces Linux. AMP: Apache, MySQL and Perl/PHP running on any operating system. LAPP: PostgreSQL replaces MySQL. LAMJ: JSP replaces Perl/PHP. There is also the insulting-sounding term WIMP, which means that Windows replaces Linux and IIS replaces Apache – this is considered to result in a much worse system than LAMP. IIS and ASP: Microsoft's Server. Despite Microsoft's dominance of everything to do with computers, their web server software sits on a relatively low 20% market share, thanks to the The Web Design Guide for Newbies |60
popularity of Apache. However, 20% of millions of servers is still a pretty substantial number of servers, and so IIS (Internet Information Server) can't be written off that quickly. IIS and Security. Among technical people, though, IIS is mainly known for its terrible security record, most famously when a security hole allowed the Code Red worm (a kind of virus) to spread between IIS servers back in 2001 . Microsoft was forced to issue press releases asking people to secure their servers, which meant that millions of webmasters had to go to Microsoft’s website and download a patch to fix the problem. This prompted many people to go and download Apache instead, so the same thing wouldn't happen again. Most of IIS' security holes were caused by services that most people don't use, simply because they were left on by default. Once an attacker was in, the damage they could do was greatly increased by the fact that IIS ran with all the security privileges available on the system – essentially, once someone got past IIS' lacking security, they could do anything to the system. For the latest version, Microsoft finally turned off unnecessary services and made the server run with fewer privileges, creating a much more secure web server. However, most of the IIS servers on the Internet today are not running the latest version, as the only way to get it is to upgrade to the Windows Server 2003 operating system – there are plenty of people still running IIS 5 on Windows 2000. IIS and Stability. Another prominent criticism of IIS is that it has a tendency to fail under heavy loads, as it can't handle very many connections at once. If you've ever seen an error that says something like 'Website Too Busy', the chances are that IIS was responsible for it. So Why Would Anyone Use IIS? The primary reason anyone uses IIS is that they created their website using Microsoft's software. This usually means that their database is Microsoft SQL, and their pages are written using ASP (Active Server Pages), the latest version being ASP.Net. ASP is easy to use, as most scripts are written in a Visual The Web Design Guide for Newbies |61
