By combining the power of a Cluster of Raspberry Pi boards, you can perform serious computing tasks and build more ambitious projects.
Building a Raspberry Pi cluster is a fun way to get a deeper understanding of computing and server systems. But what is a Raspberry Pi cluster? How do you create one, and what can you use it for once the build is complete?
What Is a Raspberry Pi Cluster?
Hosting websites, analyzing dense data, and rendering digital video footage are just a few examples of computing tasks that require a lot of processing power. And the demand for this power is always growing.
Providing enough resources to meet the needs of tasks like these can be achieved either vertically or horizontally. For vertical growth, a single computer is optimized to produce as much processing power as possible. This contrasts with horizontal growth, where additional computers are added to the system.
Raspberry Pi compute clusters are an example of horizontal system optimization. One Raspberry Pi acts as a head unit. That provides instructions to a collection of node Raspberry Pis that handle tasks. Raspberry Pi CM4 cluster setups are also known as Brambles. Rather than Compute Module 4s, you could use standard Raspberry Pi 4s (or other models), but the CM4 is more streamlined if you want a compact, efficient cluster.
You can use a Raspberry Pi CM4 cluster to host video game servers, manage your home automation system, and much more. But why would you want to build an RPi cluster?
