I am sorry if this really off-topic from this stackexchange, but I don't really know where to get the help. My group was asked to create a proposal for renovation of university's web server. The problem is the university server always flooded when students register for courses (because too many people accessing it at the same time). I must write a proposal to change this server hardware and system to improve the performance. However, I don't know where to start searching for the cost, performance, and useful information to write my proposal. Therefore, can anybody suggest some idea to which server or system I should propose?
By the way, this is the login page: Personal Information Login Page
I was thinking if there is any different in performance between using php or ajax? I guess my university use ajax, and maybe this contribute to some server problems too. One of the question I would like to ask is which language is better for university server: ajax or php?
