Open Source PHP MySQL applications are computer applications that enable you to host production sites on a large scale. There are different open source PHP MySQL applications that are available for different operating systems. You do not have to buy the software you need from a physical store, you can always order for one from the internet. Most websites offer open source PHP MySQL software in beta, mature or stable form.

With this kind of software, you do not have to worry about getting a custom Linux server. Since the process of acquiring the Linux server is too hard and time consuming, you can simply evaluate on your PC LAN if you have 1 to 100 users. Alternatively, you can make use of a Windows Apache MySQL PHP (WAMP) server. This server is effective in the evaluating of PHP MySQL software. When looking for the proper PHP MySQL application, you should get the one that has an automated installer.

Client-server network application architectures have a fixed host or server and many other clients who request the services from it. The server has a fixed address called the IP address where the packets of requests from the clients are sent. The server can work on two models-always on and sometimes on. The web and email work on client server network application architecture. It can become defunct or slow when many clients log on to it simultaneously. Thus for busy servers, virtual servers are also created.
The peer to peer architecture doesn’t need a dedicated server to connect. The peers can communicate through their own laptops and desktops. The high traffic intensive network applications use peer to peer architecture.

The P2P architecture is cheaper and mostly free of cost as the host need not pay for bandwidth and connection. Skype and PPLive use this kind of architecture. Most of the university and educational institutes use P2P architecture to stay in touch with the students and teachers.
