CESNET (Czech national e-infrastructure) review

The entry plan is VM-A with VM-A: 1 vCPU, 2 GB RAM, 15 GB SSD, priced at CZK 342 and billed monthly. That is enough headroom for staging copies, build agents and small internal tools, and it carries the same linux and windows guest options as the larger machines.

Object storage is free at CZK 0 per GB per month, and the offering is listed as free tier. The object layer is S3-compatible, so existing buckets move with little rework. Virtual servers are not free: VM-A starts at CZK 342 on monthly billing.

Billing models listed are monthly, so there is no hourly or per-second metering to rely on for short jobs. A machine switched on briefly still runs for the month, which suits always-on academic services more than bursty experiments.

Bandwidth is Shared 2x 10 Gbps uplink, not a dedicated line. Hosts sit on an in-house national research backbone with international peering, so traffic between Czech campuses is quick, while heavy export to the wider internet is shared.

Guests run linux and windows, so Linux and Windows workloads are both covered from the same platform. That suits research groups running licensed commercial tools next to open-source stacks, and support reaches them on email, phone and help centre.

Virtual servers run in CZ across 2 locations, and the storage service counts 5 regions of its own. There is no multi-country footprint, so users outside the Czech Republic should expect longer round trips.

Support runs on email, phone and help centre, covering email, phone and a help centre. CESNET is a membership association of legal entities running national infrastructure, so accounts and contracts follow Czech institutional practice rather than retail sign-ups.

CESNET is the Czech national e-infrastructure, so the natural fit is universities, research institutes and public sector teams already on the national network. Buyers outside CZ get less from the backbone and more from an operator with a wider footprint.
