Blue-Green & Canary Deployments

Zero-downtime deployments in Romania start with two identical environments and a controlled switch of traffic, so releasing a new version stops being a night-time event.

  • Instant switch between two identical environments
  • Rollback in one command, no rebuild needed
  • Schema migrations that work in both directions

VPN & WireGuard

A managed WireGuard VPN in Romania that does more than connect laptops.

  • A separate key for every device

Managed firewall and network isolation in Romania start from one rule: deny everything, then open only what is needed.

  • Default deny inbound, filtered outbound traffic
  • Databases and Redis never on a public IP
  • Regular port audits made from the outside

View the service page →

LLM & AI Application Security
