Cloud & Virtualization
VPS Infrastructure
Provider-neutral VPS estates on DigitalOcean, Vultr, Contabo, Linode or Hetzner, built to a hardened baseline with monitoring and backups from day one.
Capabilities
What we implement
- Provider and plan selection
- Hardened Linux / Windows baseline
- Reverse proxy and TLS automation
- Snapshot and offsite backup policy
Security
How it is hardened
- Key-only SSH behind a bastion or VPN
- Host firewall and Fail2ban
- Unattended security patching
- Least-privilege service accounts
Architecture
Managed VPS deployment reference
A VPS is only cheap if it is built properly once. The baseline below is applied at provisioning, not retrofitted after the first incident.
01 · Provider & provisioning
Provider chosen on workload profile, data residency, network quality and support expectations — not on headline price alone.
02 · Access control
Key-only SSHBastion or VPN entryNon-root admin usersPassword authentication disabled, management ports closed to the public internet, per-person accounts with sudo logging.
03 · Host baseline
Hardened OS imageUFW / nftablesFail2banUnattended upgradesMinimal package set, only required ports open, security updates applied automatically with reboot windows agreed.
04 · Application layer
Nginx / Caddy reverse proxyLet's Encrypt automationcPanel or Plesk (optional)Docker servicesTLS renewal automated, services isolated per user or container, control panel added only where the client administers it themselves.
05 · Protection & visibility
Provider snapshotsOffsite backup copyUptime & resource monitoringLog retentionSnapshots are convenience, not backup — an independent offsite copy is always configured alongside them.
FAQ
VPS Infrastructure questions we are asked
- Which VPS provider should we use?
- Contabo and Hetzner give the most resource per unit cost; DigitalOcean, Vultr and Linode give better network quality, APIs and support. The choice follows the workload, not a preference.
- How is the VPS sized?
- From measured load where an existing system can be profiled, otherwise a conservative baseline with monitoring and a review at 30 days — vertical scaling on a VPS is a short maintenance window, not a rebuild.
- Are provider snapshots enough protection?
- No. Snapshots live in the same account as the server, so an account compromise or accidental deletion takes both. An independent offsite copy is always configured.
- Do you manage the server afterwards?
- Patching, monitoring, backup verification and hardening reviews can be covered under a maintenance arrangement agreed in advance, or handed over with documentation if you run it in-house.
