The tiny single-board computer Raspberry Pi 4 Model B is a full-fledged replacement for a Linux desktop. The platform suits not only web browsing and application development — it can also become the "brain" of a robot or a smart home, a media center, a node of a distributed computing system or an industrial controller.

Performance check#
I decided to test the pi's load capacity by running most of my bots on it and was pleasantly surprised.
I use the standard OS: Raspbian GNU/Linux 10 (buster) armv7l, with 6 Spring Boot applications running, 5 of which are bots (4 Telegram bots); the database (mostly MongoDB) is external.
