Overprovisioning

Overprovisioning (also called overcommit) is the practice of selling more resources than physically exist — for example more vCPUs or RAM than the host actually provides. It works because customers rarely draw their full allocation at the same time, and it lowers costs for the provider. The trade-off is unpredictable performance: when several neighbours on the same host generate load simultaneously, they all compete for the same cores and your VM slows down. Bthorio deliberately runs its cloud servers with no overprovisioning — the vCPU and RAM you are assigned are fully available at all times, for predictable performance without nasty surprises.
