Server Provisioning

Bare metal, VPS, cloud instance, or dedicated GPU node. Whatever your environment we provide custom and well documented systems.

Security Hardening

CIS Level 2 benchmarks, rootless containers, AppArmor/SELinux profiles, WireGuard, and supply chain controls.

High Availability & Failover

Kubernetes, Swarm, Incus, HAProxy, Nginx, Postgres, all kept in sync. Ready and designed for any possible failure.

Backup & Disaster Recovery

Immutable off-site backups, tested restore runbooks, and documented RTO/RPO. We run the drills so the drill isn't your outage.

Kubernetes & Orchestration

Docker Swarm, clusters on bare metal, failover, or managed cloud kubernetes - we provide secure automated deployments for any environment.

Container & Virtualization

Secure, well managed scopes. Rootless, isolated micro-VMs, namespace and resource limited. Dev and Prod live in harmony.

Web Server Configuration

Nginx, Caddy, and Traefik with automated TLS, HTTP/3, edge caching, and zero-downtime reload. Apache is always available for legacy stacks.

Observability Stack

Prometheus, Grafana, Loki, Mimir, Tempo, and OpenTelemetry. Full metrics, logs, and traces in one pane. Alerts that provide details not noise.

GitOps & CI/CD Integration

ArgoCD, Flux, and GitHub, GitLab, or Jenkins. We write pipelines that work. Safety, with policies, rollback gates, and environment var protection built in.

Infrastructure as Code

Terraform, OpenTofu, and Ansible. Git checked, idempotent, easily reviewed, and version-controlled. Your infrastructure lives in Git, not in someone's head.

Servers that run themselves (almost)

Whether you need zero-downtime Kubernetes deployments, security policies baked into your CI/CD pipeline, or just want your infrastructure in Git, not in someone's head - we are here to help.
