  • The page’s ’Just Testing’ column (2GHz dual core, 4 GB RAM, 50 GB disk) is the level at which you can install the packages and the Horizon services start.
  • Your workload (network size, monitored metrics, flows, events and data retention) changes these requirements. 64-bit RHEL or CentOS 9/10, Debian 11/12 or Ubuntu 24.04 LTS.

All figures are the providers' own published list prices in USD, on-demand monthly. The index was last refreshed 2026-10-14, and every row shows the date its own price was read. Nothing here is live or negotiated pricing. Where a provider bills a public IPv4 address on top, it is added to the monthly price, the ranking and every cost per vCPU or per GB, and the row shows the parts: the server, any disk priced apart, and the IPv4 charge. Some prices exclude VAT or need a commitment; the plan notes say which. Check the provider's pricing page before you commit.
