I am sorry if this really off-topic, 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), and students browsing the information from server frequently experience page error. 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 offer in my proposal. Therefore, can anybody suggest some idea to which server or system I should propose?
By the way, this is an example of the login page: Login Page
I was wondering if there is any different in performance between web language? Therefore, I am not sure if changing that would help.
