I work for a large multination company, which boast possibly the largest intranet in europe.
The microsoft parts of this intranet are taking, upto 9,000,000 hits per day, using an assumtion of 10 hits per page impressiion (GIFs, CSS etc) that is 900,000 page impressions per day, I can’t speak for the linux hosted parts as I don’t have access to ALL of the data.
Compare to an avarage joe-doe blog site or even the avarage small business web site (4,000 page impressions per day, this is real data from a small 10 employee ecommerce web site) that is quite impressive.
Then enter the BBC , from the BBC annual report “bbc.co.uk’s reach grew by 16.2 per cent over the year, with page impressions averaging over 3.6 billion per month.” that is 120 Million page impressions per day (or using the same assumption I made above 1.2 billion server hits per day)
one word
WOW !!!!!!!!!!!!!!!!

At a first stab there must be 400 questions which may be in the mix. The trick is to work out which ones are Critical to success, which ones have no impact, which ones can be linked and therefore become a single decision with many results. Does the implementation mean some of these decisions can be made after Go live (VMware lets you add extra resource to a guest operating system)
How much input can the business customer provide?
How much input can the application developer provider?
What assumptions can you make?

In todays must be green society many corporates are looking at ISP style web hosting farms to consolidate the Intranet , extranets and Internet web sites onto fewer servers with better engery cost and perfromance.
Building a large web platform(s) is not something you should take lightly, it is a not a simple case of “right click BOSH”, you have to concidure many things
- How things may interact?
- How you control it?
- How you track who owns what ?
- How do you charge for it?
So I have started to compile a Web farm checklist, which will grow over the next few months as i try to document some parts of the last 4 years of my working life.
