Raspberry Pi 4 Model B ' was announced on June 24, 2019. Raspberry Pi 4 was talked about that CPU and RAM evolved more than the previous model Raspberry Pi 3 Model B + , and also equipped with Gigabit Ethernet and USB Type-C port, the server that builds Raspberry Pi's official blog It is used for

The following article summarizes how much the spec of Raspberry Pi 4 has been upgraded.

Mystic Beasts , a provider of personalized hosting services using Raspberry Pi, has provided samples of as many as 18 Raspberry Pi 4s from the Raspberry Pi Foundation. Originally I was thinking of building a cloud server using that Raspberry Pi 4, but when Raspberry 4 Model B was received, the essential functions for cloud server operation were not installed in the firmware, and I abandoned the crying cry And. So I thought that I wanted to build Raspberry Pi's official blog server with Raspberry Pi.

And the cluster which built the WordPress environment with 18 Raspberry Pi 4 is the following image. 14 out of 18 (56 cores, 56 GB RAM) handle PHP code execution, 2 (8 cores, 8 GB RAM) process static files, 2 (8 cores, 8 GB RAM) memcached Seems to be running.

At midnight on June 22, 2019, production traffic migrated from the existing server to the Raspberry Pi 4 cluster. Raspberry Pi 3 Model B + took about 2.1 seconds to generate pages, while Raspberry Pi 4 Model B generated pages in about 0.8 seconds. Mystic Beasts anticipates that typical end-user operations should be faster as most pages are served from the cache.

However, Mystic Beasts stated, “Sorry, this configuration is not the standard production environment of Raspberry Pi's official site. The Raspberry Pi 4 built this time is not online storage, but uses local storage with an SD card. 'I say.' Furthermore, the operating system seems to be

Debian 10 Buster , which is one of the Linux distributions, but since Debian 10 Buster is officially released on July 6, 2019, it is still installed before the test version before release. Therefore, he warns that 'Never use this Raspberry Pi cluster configuration for mission critical websites'.

At the time of writing, Raspberry Pi's official blog was built on a Raspberry Pi 4 Model B cluster, but the whole stack was not migrated, and the front end load balancer, download server, apt repository server is hard except Raspberry Pi. And are divided into three data centers. Also, it seems that all databases have not been migrated to Raspberry Pi.

Mystic Beasts says it is possible to move the entire stack to Raspberry Pi, but it is still a test, and that if something happens it will be able to quickly switch to hardware other than Raspberry Pi. .
