VMware changed its licensing. Your renewal quote tripled. Or maybe you're running everything on bare metal and wondering if there's a better way. Proxmox VE is the answer more Vilnius businesses are arriving at — open-source server virtualization that does what VMware does, without the licensing trap. I've been deploying and managing Proxmox clusters for years, and I can tell you exactly where it shines and where it needs careful planning.
This is not about selling you Proxmox subscriptions. It's about understanding your workload, designing the right architecture, and implementing it so your team can manage it day-to-day. One engineer, hands-on, start to finish.
What's Included
Proxmox VE installation and initial configuration
Cluster setup — 2–5 node clusters with high availability
Storage architecture — ZFS, Ceph, NFS, iSCSI, local NVMe
VMware to Proxmox migration — VM conversion, network remapping, testing
Monitoring and alerting — Prometheus + Grafana dashboards
Firewall rules within Proxmox — cluster-level and VM-level
Performance tuning — CPU pinning, NUMA, balloon memory, IO scheduling
GPU passthrough for AI/ML workloads
Documentation and knowledge transfer for your team
Ongoing support retainer — remote administration and troubleshooting
Numbers That Matter
Proxmox VE license: free (community) or from €110/year/socket (subscription)
VMware equivalent: typically 5–15× more expensive after 2024 changes
Typical 3-node cluster setup: 16–24 hours of engineering work
VMware migration (10–20 VMs): 8–16 hours depending on complexity
Backup server setup with PBS: 4–6 hours
Hourly rate: €35 on-site, €25 remote
Ongoing management retainer: from €100/month
How It Works
First, I assess your current infrastructure — what you're running, where, on what hardware. If it's a VMware migration, I map every VM, its dependencies, and network connections. Then I design the Proxmox architecture: cluster topology, storage layout, network scheme, backup schedule. Implementation follows — typically 2–4 days for a standard cluster. I test everything, document the setup, and train your team on daily operations. After handoff, I'm available for ongoing support.
Is Proxmox Ready for Production?
Absolutely. Proxmox VE runs in production at thousands of companies worldwide, from startups to enterprises. The web UI handles 90% of daily tasks. ZFS provides enterprise-grade storage with snapshots and checksums. Ceph enables distributed storage across nodes. The backup system (PBS) is excellent — incremental, deduplicated, encrypted. The main consideration is planning: Proxmox gives you full control, which means you need someone who knows how to use it. That's where consulting pays for itself — a well-designed cluster runs for years with minimal intervention.
Key Takeaways
Proxmox VE is a production-ready VMware alternative at a fraction of the cost
Migration from VMware is straightforward with proper planning
ZFS + PBS gives you enterprise backup without enterprise pricing
One engineer handles design, implementation, migration, and support
Transparent pricing: cluster setup from €600, migration from €300

Complete IT maintenance for business
Computer is slow. Network drops. Printer won't print. Accounting software won't open at 9 AM. Usually at that moment you're looking for someone to call — and can't find anyone. We are the team that's always available. We handle all IT work: servers, networks, employee workstations, cabling systems, 24/7 monitoring. You focus on business — we make sure everything runs.

Every day dozens of businesses lose everything: accounting encrypted, client database gone, operations halted. Average ransom — €110,000. We developed our own protection methodology Vexler Reef™ — a four-level system that prevents viruses from reaching your data. And your backups are stored in a way that even the virus itself cannot erase them. Our clients have had 0% data loss over our entire history.

Business pays for what saves time and money. We free your team from routine: virtual assistants, chatbots that answer clients on their own, automatic processing of requests and reports, voice search across documents. Works even if you don't have a CRM or complex infrastructure — we configure everything to fit your processes.

A website is a tool that works for you 24/7. Unique design that sticks. Convenience that lets the client solve their task in one click. And most importantly — when someone searches for your service on Google, they find you, not a competitor. We build projects with search engine logic in mind: proper structure, clean code, local listings, Google Business Profile. Security you can trust. No fluff — just substance.

Wi-Fi networks that don't drop — and work for your brand
Wi-Fi doesn't work underwater. That's physics. But for our clients — it does. We build fast networks that cover any area without speed loss: office, restaurant, hotel, a 2,000 m² estate with guest house. POS stays connected, Zoom doesn't lag, guests are always online. At the entrance — a branded login page where you showcase your services, promotions, and socials. Wi-Fi becomes a storefront, not just a convenience.

Lights on when nobody's home. Heating blasting an empty house. Overpaying €500–1,500 per year. A smart home fixes this: lights turn on when you enter, heating knows when you're away, voice controls everything — 'turn off bedroom', 'we're leaving' and everything shuts down. Plus security: AI cameras, motion sensors, lock control from your phone. Save 15–30% on bills with total peace of mind. Everything runs locally, no cloud — private.

/07 — ABOUT
Vexler is a team of IT engineers in Vilnius.
Networks · Security · Automation
For 15 years we've been building infrastructure for small and mid-sized businesses: hotels, coworking spaces, offices, clinics, manufacturing, auto services.
What we've learned in that time is simple: pretty dashboards don't protect data. Backups that even a virus can't erase — and disciplined processes — do.
That's why we developed Vexler Reef™ — a four-layer preventive protection methodology. It's included in every service contract we sign.
One team. One methodology. Our waters: Vilnius · Europe · America.
Website, CRM, AI chatbot, Zoom, dashboards. Everything shines and works — until the first outage. Then it turns out nobody looked under the surface for years.

Underwater — what decides everything
Backups nobody ever tested. Passwords 'admin/admin' on the router. Server last updated in 2019. Access rights of former employees still active. This is where disasters are born — and where they can be stopped.

/03/03 — PROCESS
How we work.
Five steps from the first call to a calm infrastructure. From symptom to cause, from cause to methodology. No magic, no 'let's try rebooting'.
01
Step 01
We listen and audit
We start with a free consultation: what hurts, what's needed, what are the goals. Then — an audit of what we'll be working with. We break infrastructure down to atoms: network, servers, backups, access. Website — technically and semantically. Processes — where routine eats time. No diagnosis — no treatment or building.
02
Step 02
Report and honest picture
We prepare a report in business language: what's fine, what's on the edge, what's broken — or what we'll build from scratch if it's a new project. With photos, diagrams, numbers. You see the real state of affairs for the first time — without tech fog or 'we need to redo everything'.
03
Step 03
Recommendations and plan
Based on the report, we say what to change, what to replace, what can stay. What's urgent, what can wait, what will save money. Transparent estimates, priorities, and alternatives. You make the decisions — we provide facts, not sell 'packages'.
04
Step 04
Implementation and launch
We do the work: build the network, configure security and fault tolerance, develop the website, launch automation, assemble the smart system. We test everything, document it, hand over access. We bring it to a state you can live with peacefully.
05
Step 05
Ongoing managed support
We take the result under permanent support. One contract, one team, one responsibility for everything: infrastructure, security, website, automation, AI assistants, smart systems. You focus on business — we make sure everything runs.
/AI — AUTOMATION
One creature. Many roles.
Like a siphonophore — a colony of specialized cells that lives and hunts as a single organism. One agent reads email, another writes replies, a third searches the archives. You see the result — not the process.

Important: some services are not billed hourly — project work (websites, networks, smart home, Vexler Reef™), managed services, and urgent SLA visits are calculated individually with a fixed estimate.
Why don't we show fixed packages?
Every infrastructure is unique. Number of computers, servers, security requirements, working hours, geography. Packing this into three universal packages means either deceiving the client or deceiving ourselves. We do it differently: a free 30-minute consultation, an audit (if needed), an honest estimate for your specific task.
