My Raspberry Pi Tower is growing steadily. At this moment I have 4 Raspberry Pi’s (mini computer) running. One Pi is designed as an Access Point to the Internet and provides the SSL offloading. Furthermore, he routes the HTTP traffic via an Apache Reverse Proxy to the underlying three Pi’s. These Pi’s are arranged as web server and provide 22 websites. The advantage of this solution is that the total energy consumption (including gigabit switch) is approximately 30 Watt and the websites still provide a good response.
