Platform capabilities

The hostd Public Cloud is a reliable, scalable, and secure infrastructure (IaaS) built on top of leading enterprise-grade technologies.

Technology Stack & Hardware

We use only proven and reliable hardware from global industry leaders to ensure maximum performance and stability for your workloads.

Infrastructure LayerTechnology
VirtualizationProxmox VE (stable enterprise repository branch based on KVM/QEMU)
Physical ServersExclusively Dell PowerEdge servers with AMD EPYC processors
Network GearSwitches and routers from Dell PowerSwitch and Juniper
Backup SystemProxmox Backup Server (PBS) (isolated and deduplicated datastore per project)
VM StorageDistributed all-flash NVMe storage (SDS) with RoCEv2 and asynchronous io_uring

Storage Performance

Thanks to all-flash NVMe storage and modern transmission protocols, typical latency for 4k randwrite operations in t1q1 mode (1 thread, iodepth=1) with fsync is only about 0.11 ms (measured directly at the hypervisor level).

Note: This is an infrastructure metric, not an SLA for your application inside the VM, as the guest OS file system and emulation add their own overheads.

Available Zones

  • WAW-AMD1 — Warsaw, Poland. The infrastructure is located in certified Atman WAW-2 and Equinix WA2 data centers (Tier III+ compliance). Your data and backups physically remain in Poland.

Compute Resources

  • Modern Linux OS: Instant deployment of clean and stable images of Ubuntu, Debian, Rocky Linux, and AlmaLinux.
  • Flexible CPU modes:
    • Performance: Dedicated vCPUs with maximum performance (up to 100% CPU time) for high-load systems.
    • Eco: Balanced utilization up to 50% CPU time for standard web applications and services.
    • Slim: Optimal mode up to 25% CPU time for testing, development, and light background tasks.
  • Instant Scaling (Resize): Increase vCPU, RAM, and system disk size on-the-fly without stopping the system.
  • Guaranteed High Availability (HA): Free automatic protection against hardware failures. If a physical host fails, your VM is automatically rebooted on another working host in less than a minute.
  • Snapshots: Take an instant snapshot of the disk state for quick and safe rollbacks during system updates or testing.

Networking & Security

  • Floating IPs: Real public IPv4 addresses assigned directly to your instances’ network interfaces without overlay NAT, easily transferable between servers.
  • Private Networks (VLAN): Create fully isolated Layer 2 local network segments for secure communication between instances, featuring built-in IPAM (IP Address Management).
  • Reverse DNS (PTR): Conveniently manage PTR records for your public IP addresses directly through the portal.
  • Firewall: Set up traffic filtering rules on public WAN interfaces.
  • Security Groups: Reusable firewall rule templates that can be quickly applied to multiple virtual machines.
  • Network Map: Interactive visual representation of your entire infrastructure, showing connections between instances, private networks, and gateways.
  • External VLAN: Integrate the cloud with your physical hardware (bare metal or on-premises) via a dedicated Layer 2 channel.

Cloud Gateway

A specialized, fully managed infrastructure router for your private networks.

  • Full Automation: Configure NAT, port forwarding, VPN, and proxying without the need to manually administer the router’s operating system.
  • WireGuard VPN: Fast and secure access for administrators and developers to local cloud resources over an encrypted tunnel.
  • Reverse Proxy: A high-performance reverse proxy based on Caddy with automatic Let’s Encrypt SSL certificate generation upon the first domain request.

Backups & Recovery

An integrated, fully automated backup system powered by enterprise-grade Proxmox Backup Server (PBS) technologies.

  • Regular Schedules (Backup jobs): Configure flexible automated backup schedules for groups of virtual machines.
  • Incrementality & Deduplication: Backups copy only modified disk blocks and undergo deduplication at the storage level, resulting in massive savings in disk space (on-disk size) and reducing storage costs.
  • File-level Restore (File restore): Browse the backup file tree and download individual files or folders directly from the backup without a full system rollback.
  • Backup Protection: Protect critical backup copies from accidental or automatic deletion by retention policies.

Management & Billing

  • Team Access: Add members by email and assign roles (Superadmin, Admin, Auditor) for secure joint infrastructure management.
  • Hourly Billing: Charges are accrued solely for actually allocated resources with hourly precision.
  • Two Payment Models: Pay in advance (Prepaid with auto-reload) or after consumption (Postpaid with invoices at the beginning of the month).
