[00]Independent support for open-source infrastructure

Open-source infrastructure, supported like it matters.

Rtec deploys, hardens and supports OneUptime, Proxmox, XCP-ng and Headwind MDM, on your own hardware, in your cloud, or anywhere in between. You keep control of your platform. We keep it running.

[01]Services

Four platforms. One team that knows them deeply.

We focus on a small number of open-source products and go deep on each, from first install to the upgrade you've been putting off.

ObservabilityLead service

OneUptime

Uptime monitoring, status pages, incidents, on-call, logs and traces on one open-source platform. We install it on your infrastructure and keep it healthy, or help your team get the most from OneUptime Cloud.

  • Self-hosted
  • Air-gapped
  • Cloud
  • Production install with Docker Compose or the Kubernetes Helm chart
  • Hardening: TLS, SSO, network policy, secrets and backups of the data stores
  • Monitors, status pages, on-call rotations and escalation policies set up for you
  • Version upgrades tested before they reach production
  • Migration from other monitoring and status-page tools
  • Ongoing support for both self-hosted and OneUptime Cloud teams

Virtualization

Proxmox VE

An open-source virtualization platform for VMs and containers, and a credible alternative to VMware. We design, build, migrate and support Proxmox environments of any size.

  • On-premises
  • Colocation
  • Hybrid
  • Architecture and hardware sizing for new clusters
  • Migration from VMware ESXi and Hyper-V with planned cut-over windows
  • Networking: bonds, VLANs, SDN and the Proxmox firewall
  • Backup and disaster recovery with Proxmox Backup Server
  • Cluster upgrades, health checks and performance tuning
  • Managed support with a named team that knows your environment
Storage & HA expertise ↗
Virtualization

XCP-ng

A fully open-source, Xen-based hypervisor managed with Xen Orchestra. We deploy, migrate and support XCP-ng pools, from a single host to clustered production environments.

  • On-premises
  • Colocation
  • Hybrid
  • Pool design, host installation and Xen Orchestra setup
  • Migration from VMware ESXi and Citrix Hypervisor (XenServer)
  • Shared storage on NFS or iSCSI, and hyper-converged storage with XOSTOR
  • Xen Orchestra backups: delta, replication and tested restores
  • Rolling pool updates, HA and live migration
  • Ongoing support, with escalation to the vendor where you hold a subscription

Mobile devices

Headwind MDM

Open-source mobile device management for Android fleets in retail, logistics and field service. We run the server, enrol your devices and handle day-to-day fleet support.

  • Self-hosted
  • Hosted
  • Server deployment on your infrastructure or hosted for you
  • QR-code enrolment, including devices without Google services
  • Kiosk mode, app distribution and remote configuration
  • Advice on open-source vs Premium/Enterprise licensing
  • Staff training and documented runbooks for your team
  • Front-line support with escalation to the vendor when needed

[02]Self-hosted or cloud

Your infrastructure or theirs. Supported either way.

Most of our OneUptime and Headwind MDM clients run the open-source editions on their own infrastructure. Others prefer the vendor's cloud. We support both, and the move between them.

Self-hosted, on your infrastructure

Run the open-source editions on your own servers, private cloud or air-gapped network. Your data never leaves your control, and there are no per-seat licence fees. We handle the install, the hardening and the upgrades.

  • Bare metal, VMs or Kubernetes
  • Air-gapped and regulated environments
  • Your backups, your retention policy

Cloud, managed by the vendor

Prefer not to operate the platform yourself? We help you onboard to the vendor's cloud offering, configure it properly and support your team day to day, with an exit path to self-hosting if your needs change.

  • Onboarding and configuration
  • Integrations with your existing tools
  • Ongoing admin and user support

[03]Proxmox expertise

Experts in Backup Server, ZFS storage and Ceph clusters.

From a single host to full high-availability environments. The storage and backup layer is where virtualization projects succeed or fail, so that's where our engineers spend their time.

PBS

Proxmox Backup Server

Incremental, deduplicated and encrypted backups with verification jobs, off-site sync and tested restore procedures, not just backups that look green.

ZFS

ZFS storage

Pool layout, mirrors and RAID-Z, special and log devices, compression, snapshots and replication, tuned to your workload and your disks.

CEPH

Ceph clusters

Hyper-converged Ceph with sensible failure domains, network separation, CRUSH rules and capacity planning that survives a node going away.

HA

High availability

Corosync quorum design, HA groups, fencing and live migration, so a hardware failure becomes a non-event instead of an outage.

From single host to full HAWe design for where you're going
  1. Single hostOne server, ZFS mirror, PBS backups off-box
  2. Small clusterThree nodes, shared quorum, replicated ZFS
  3. HA clusterHyper-converged Ceph, automatic VM failover
  4. Multi-siteOff-site PBS sync and a documented DR runbook

[04]How we work

From first call to steady state.

A clear, written plan before any work starts, and documentation you keep when it's done.

  1. Discovery call

    A 30-minute conversation with an engineer about what you run today, what hurts, and what good looks like.

  2. Assessment & proposal

    We review your environment or requirements and send a written proposal with scope, timeline and fixed or capped pricing.

  3. Deploy or take over

    We build it new or adopt what you already have, then document everything so nothing lives only in someone's head.

  4. Ongoing support

    Upgrades, monitoring and help when you need it, under a support agreement sized to how critical the system is.

[05]Engagement models

Support sized to how critical the system is.

Every agreement is scoped to your environment. Coverage hours and response targets are written into your contract, not left to a pricing page.

[06]Why Rtec

The control of open source, with someone to call.

Open source first

We build on the community editions wherever they fit, and recommend paid licences or vendor subscriptions only when they add real value.

Engineers, not ticket routers

The people who answer your request are the people who build and run these platforms.

No lock-in

Everything we build is documented and handed over. Your team, or another provider, can take it from there.

Self-hosted or cloud

Same standard of support whether the platform runs in your rack or in the vendor's cloud.

[07]FAQ

Questions we hear often.

Something else on your mind? Ask us directly.

Are you affiliated with OneUptime, Proxmox, XCP-ng or Headwind MDM?

Rtec is an independent services company. We deploy and support these open-source products, and we can help you purchase vendor licences or subscriptions where they're needed. Product names belong to their respective owners.

Do I need to buy a licence or subscription?

Often not. OneUptime Community Edition is Apache 2.0, Proxmox VE is AGPLv3, XCP-ng is GPLv2, and Headwind MDM has an open-source edition. Vendor subscriptions add things like enterprise repositories, extra features or direct vendor support. We'll tell you honestly whether you need one.

Do you support OneUptime Cloud as well as self-hosted OneUptime?

Yes. Most of our OneUptime work is self-hosted, but we also onboard and support teams on OneUptime Cloud, and can help you move between the two.

Can you migrate us off VMware?

Yes. We plan VMware ESXi and Hyper-V migrations to Proxmox VE or XCP-ng workload by workload, with tested rollback and agreed maintenance windows.

Can you take over an environment someone else built?

Yes. We start with an assessment of what's there, fix anything risky, document it, and then support it like anything we built ourselves.

What happens if the problem is a bug in the software itself?

We reproduce it, find a workaround to keep you running, and report or escalate it upstream to the project or vendor with everything they need to fix it.

Do you work remotely or on-site?

Remote by default, over secure access you control. On-site work for hardware installs and data-centre visits can be arranged.
