The Raspberry Pi single-board computer was designed primarily for teaching and tinkering some eight years ago, but since 2012 the SBC has been applied to a wide variety of applications outside of the education world.
Mythic Beats, the company that provides hosting services to the Raspberry Pi Foundation, recently started to offer hosting powered by a Raspberry Pi 4.
Several weeks ago, the Raspberry Pi Foundation decided to try running its website on a Raspberry Pi 4-based cluster featuring 18 SBCs (quad-core SoC at 1.5 GHz, 4 GB of RAM). 14 boards were used as dynamic LAMP (Linux, Apache, MySQL, PHP) servers, two were static Apache servers, and the remaining two served as a memcache-powered memory store.

The organization says that the cluster worked good enough to serve around a million of visitors a day for a couple of days and could even handle the load when ‘tens of millions visitors’ headed to the Raspberry Pi 4 website the day of the Raspberry Pi 4 8 GB launch.
Following the successful experiment, Mythic Beats began to offer hosting services using Raspberry Pi 4 SBCs. For £7.45 per month (~$9.40), Mythic Beats offers a Raspberry Pi 4 server with four cores, 10 GB of NFS storage, a 1 GbE NIC, and 1 TB of bandwidth.
According to Mythic Beats, a Raspberry Pi 4 server performs substantially better than Amazon Web Services’s a1.large and m6g.medium Arm instances at a much lower price.
Raspberry Pi 4-based hosting is not without caveats. SD memory cards are not the most reliable storage devices these days, so if one fails, the whole node will need a manual intervention, which takes a lot of time.
The Raspberry Pi Foundation offers a solution though: build a large Raspberry Pi 4-powered cluster with loads of redundant units and just disable the failed nodes when they break down.
