Sd2.0-Dudu communication and blog site architecture

Today is the first time I saw Dudu. It is indeed the same kind of enthusiasm, modesty, and affinity as those in the garden. At the same time, I also saw several people I have heard of but never met: zeng denggao, Chapter E of Mencius ,. net Nanjing club owner and some csdn Daniel.
I talked with Dudu about the current operation of the bloggers and the current website architecture of the blog Park. At present, the main work of the blog Park is done by Dudu, currently, R & D teams are being built in Zhangjiang campus in Shanghai. It seems that the financing of the blog Park is not very optimistic. I specifically asked whether the "Flash Memory" function in the blog can be embedded in the blog. I got a positive response. At present, it seems that there are a lot of requirements in front of Dudu, but there is still a lot of work to organize human resources for meticulous research and development, and efforts need to be made to develop the blog Park.
I had a rough idea about the website architecture of the blog Park. Currently, the website uses four servers, three web servers, and one data server. At that time, I was wondering, are three servers distributed? This is not the case. Instead, one is responsible for the entire blog Park, one is responsible for other blog sites, and one is responsible for other applications. In this way, it is still centralized management. I don't see the. Net-based platform distributed website I want to know. The backend data server uses MSSQLServer 2005. websites are not static, and the cache uses the cache method provided by the Microsoft enterprise database. A csdn brother recommends using memcached, the reason for this is that the enterprise database often loses data. NET application, I am not very clear.
