UpCloud and Contabo are both EU-based unmanaged platforms -- but the infrastructure priorities differ. UpCloud is built around I/O consistency and reliability: MaxIOPS SSD architecture, a financially-backed 99.99% SLA, and dedicated CPU resources. Contabo is built around resource density: more RAM and storage per dollar than most EU unmanaged VPS options, with shared CPU architecture.

What you get that Contabo doesn't offer

MaxIOPS SSD architecture with dedicated I/O throughput per server. A financially-backed 99.99% uptime SLA. Dedicated CPU resources with no shared-core contention. Private cloud deployment model under the same account. Locations in Amsterdam, London, Frankfurt, Helsinki, Singapore, New York, and Chicago.

What you give up

Contabo's RAM and storage density per dollar -- more gigabytes per euro at Contabo than at UpCloud's pricing tier. For RAM-intensive or storage-heavy workloads, Contabo's resource model sits outside UpCloud's pricing structure.

What you get that UpCloud doesn't offer

More RAM and storage per dollar than most EU unmanaged VPS options. Full root access with standard Linux distribution options. A cost floor for RAM-intensive or storage-heavy workloads outside UpCloud's pricing structure.

What you give up

UpCloud's MaxIOPS SSD I/O architecture. A financially-backed 99.99% SLA. Dedicated CPU -- shared CPU allocation at Contabo means resource contention can become part of normal capacity planning. Contabo publishes no uptime SLA. Contabo's support model is less suited to time-sensitive escalation.
