Hello to everyone. This email will probably be quite lengthy so please
bear with me. What I am asking is quite important to me, so I will try to
be as detailed as possible.
I have spent the last hour pouring over this list's archive. I have found
some great information and a lot of you appear to be quite helpful. I just
want to thank everyone in advance for their help. If I have missed
something obvious or my question is redundant, then please point me towards
the appropriate links and I will read them right away.
I, along with several other people am starting a business which will depend
heavily on its web presence. Unfortunately, I am in the all too common
position of having to make technical decisions that will have repercussions
on the future well-being of said business, with little to no budget. It is
crucial that the solution I pick, handle what we hope will become a very
large load in the not-to-distant future (whether this happens or not is a
question for another day, heh). To this end, I am very interested in using
the LAMP (Linux+Apache+MySQL+PHP) approach. I have experience with all of
these technologies, but I am definitely not in a position to vouch for
their worthiness for use in a large scale application running beneath a
To quantify LAMP's ability, is it appropriate for say, sites that generate
on the order of 5 million unique hits per day? If not, where would you
draw the line? At 500,000? Or 1 million? If so, how much higher could it
go possibly? 10 million? 20?
Keep in mind that we have no problem heavily optimizing the application
(code tweaks, cacheing, etc).
We looked into and even began development in JSP w/ Tomcat but found Tomcat
to be exceedingly unstable for production use (not that it was ever really
meant for it). And of course, the other available application servers
were well beyond our budget. Also, time constraints have forced us to look
for a faster-to-develop alternative.
Just a couple of details about the application we intend to develop. It
will be very database intensive (many queries per page) and will also
provide real-time payment support (for which transactions are a must).
So, what say you? Given all that I have said, is LAMP appropriate? Will
PHP and maybe even more importantly, MySQL be able to scale well? I have
no doubt that MySQL is fast, but just how scaleable is it? Will it die
beneath the kind of loads I have described?
What would be *most* helpful to me is if you could provide web sites that
exist currently and experience this load and are using LAMP
I hope you are still with me! Thanks a lot for taking the time to read
this and I would appreciate greatly any help that can provide.
