Do any solutions for the automatic management&#x2F;setup of a large cluster of node + arm already exist? Managing a few, yet powerful servers is already tricky - it can only get worse when dealing with loads of low-power servers when you don&#x27;t completely automate the management.<p>Furthermore, I doubt the Pi is an ideal candidate for a server - the CPU performance might be adequate for node.js microservices, the IO performance and data persistency metrics of an SD card are horrible. At least for databases (in which single machine performance still trumps a cluster for reasonable loads and if you want some data integrity guarantees, ie. ACID), I still cannot forsee the move towards a lot of Pis.
