Who We Are

A senior-level infrastructure agency. Not a volume shop.

We are a small, senior-level team specializing in private cloud and cost optimization. Founded in 2009, we work from Ekibastuz, Kazakhstan (GMT+5) — serving clients worldwide.

Our core focus is helping companies reduce infrastructure costs by 2-5× — replacing expensive cloud and SaaS solutions with efficient, production-grade environments built on Proxmox and Ceph.

All architecture decisions, migrations, and critical work are handled personally by the lead engineer with 20+ years of experience. No outsourcing. No junior delegation. Ever.

Clients come to us when:

  • Cloud costs keep growing and become difficult to control
  • Infrastructure is unstable, slow, or hard to scale
  • Proxmox or Ceph clusters are misconfigured or unreliable
  • Backup and disaster recovery systems don’t work as expected
  • They need senior expertise they can’t hire in-house

What We Achieve

Results, not just technology.

Cut Cloud Costs 2-5×

Replace expensive cloud with efficient private infrastructure

  • Migrate from AWS, VMware, SaaS to private cloud
  • Proxmox + Ceph clusters tuned for your workload
  • 1,000+ VMs, petabyte-scale — no performance tradeoffs

Deploy in Minutes, Not Days

Infrastructure as Code that actually works in production

  • Puppet, Ansible, Terraform — your stack, automated
  • One-command provisioning — DHCP, PXE, cloud-init
  • CI/CD pipelines designed for real infrastructure

Sleep While We Watch

24/7 monitoring with 2-minute SLA response

  • Zabbix at scale — 1,500+ hosts, 1M+ monitored items
  • Proactive alerts — we fix issues before you notice
  • Monthly reports, root cause analysis, capacity planning

Deep specialization, not surface-level familiarity.

Proxmox + Ceph HA Cluster Build (4 Nodes) + VPC Automation

Apr 2026

Built production-style Proxmox cluster (3+1 nodes) for DevOps platform. Fixed IPMI/KVM access, mapped Cisco VLANs/LACP, deployed Proxmox+Ceph with HA and live migration, built Foreman+Puppet PXE with 3-VM VPC templates.

Flynet has done an amazing job in helping us to take this ProxMox/CEPH cluster design from concept to beta. He is extremely knowledgeable, committed and well organized.

Ceph Octopus Cluster + S3 RGW (3 Nodes, 12×18TB, HA)

Apr 2026

Deployed Ceph Octopus cluster (3 MON/MGR, 12 OSD), configured dedicated cluster network, set up RGW on all nodes, built Erasure Coding pool (6+4). ~112 TiB usable from ~196 TB raw.

Ceph installed perfectly!

Proxmox + Ceph Production Cluster Audit & Automation (8 Nodes)

Apr 2026

Pre-migration QA for 8-node Proxmox+Ceph cluster with Arista networking. Built Proxmox automation with Puppet, audited OS, kernel, packages, corosync, networking, logs, SMART, storage, and Ceph PG/CRUSH/latency.

Great work by Flynet. Very strong Linux engineer!!

Xen + Ceph Live Migration Fix (Debian Buster, No-Downtime)

Apr 2026

Production Xen hypervisors with Ceph RBD storage. Live migration broke after Xen upgrades. Built 2-node Xen+Ceph lab, implemented xl migrate --live via nc listener + systemd unit. Migration time reduced ~22s→~13s.

Very grateful the help and assistance provided, thank you.

Fixing Proxmox + Ceph Slow I/O (Cluster Freezes on Backups)

Apr 2026

Production Proxmox+Ceph cluster had severe I/O slowdowns and freezes during backups. Added Zabbix visibility, traced latency to Bluestore WAL/DB, tuned SSD scheduler, rebuilt WAL/DB layouts, enabled RBD lz4 compression.

Excellent job by Flynet as always.

QEMU 4.1 + Xen 4.13 Ceph RBD Disk Open Failure

Apr 2026

Production Xen hosts using Ceph RBD. After upgrade to QEMU 4.1/Xen 4.13, VMs failed to start — RBD disk open error. Reviewed QEMU RBD URI parsing changes, corrected RBD drive syntax and auth method.

Very happy, thank you for your work again.

How to Engage

From quick consultations to full infrastructure builds.

Frequently Asked Questions

Quick answers about how we work.

What's the difference between your Cloud Server and Infrastructure Engineering?

Cloud Server is a DIY VPS — you get a server and manage it yourself. Infrastructure Engineering is a done-for-you service — we design, build, and manage your infrastructure. You focus on your business; we handle the entire stack.

Do you work with small businesses or only enterprises?

Both. Our 225+ projects range from 30-minute consultations to multi-month infrastructure builds. Whether you need a quick fix or a full datacenter stack — we can help.

How quickly can you start?

An initial infrastructure audit is delivered within 24 hours. Project start is typically 1–3 business days, depending on scope and urgency.

Do you outsource any work?

No. All architecture decisions, migrations, and critical work are handled personally by our lead engineer. No junior delegation. No subcontractors. Ever.

What's your technology stack?

We specialize deep, not wide: Proxmox VE, Ceph, Linux, Puppet, Zabbix, BGP, and KVM virtualization. For automation we use Puppet and Ansible. For monitoring — Zabbix at scale (1,500+ hosts).

Do you offer 24/7 support?

Yes, for Extended Support clients. SLA-backed with an average 2-minute response time. Monitoring, alerts, and proactive maintenance are included.

Can you set up and maintain 1C-Bitrix?

Yes. Full server stack for 1C-Bitrix on Linux: web server, database, CRM configuration, backup, and ongoing maintenance. We've been doing this for years.

What payment methods do you accept?

Crypto (BTC, USDT), PayPal, bank transfer. For projects, we use staged payment — you pay as milestones are delivered, not upfront.
