Infrastructure & Cloud — Managed Kubernetes
We design, build and operate Kubernetes platforms on your own hardware or European data centres — and migrate you off the hyperscaler without downtime. Real architecture, run by real infrastructure and network engineers.

Why companies are coming back
01 — Cost
Pay-per-use pricing punishes the steady, predictable workloads most companies actually run. On your own hardware, capacity is a number you decide once — not a surprise you discover monthly.
Predictable capacity beats elastic billing
02 — Sovereignty
Regulators, customers and procurement teams increasingly ask where data physically lives and who can compel access to it. Your racks — or a European data centre — is an answer that ends the conversation.
EU residency, auditable end to end
03 — Control
Egress fees, opaque quotas, services deprecated on someone else's schedule. Running your own platform turns infrastructure from a subscription back into an asset.
Your platform, your roadmap
The migration
Your current environment keeps running untouched until the cutover is rehearsed, reversible and ready. No big-bang weekends.
What we build
Everything lives in your repositories, fully documented. The platform is yours from day one — we just happen to run it better than anyone else would.
01
Kubernetes platform
Production-grade clusters on your own hardware or European data centres. Sized for your workloads, not a template.
02
Network architecture
Segmentation, routing, load balancing and firewalling designed by network engineers — from the rack up, not from a console down.
03
GitOps delivery
Every change to the platform flows through version control. Deployments are reviewable, repeatable and reversible.
04
Observability
Metrics, logs, traces and alerting from day one. You see what the platform sees — no black boxes.
05
Backups & recovery
Automated backups with retention policies and recovery objectives that are tested, not assumed.
06
Security hardening
Least-privilege access, network policies, encrypted secrets and a paper trail. Secure by default — it's in our name.
The team behind it
Anyone can apply a Helm chart. Knowing why the packet didn't arrive, why the disk is slow, or where a workload should physically live — that takes people who have built networks and data centres, not just consumed them.
Network engineers, not console operators
The people designing your VLANs, BGP sessions and firewall rules are the same ones who answer when a packet goes missing.
Infrastructure engineers who know the metal
Kernel tuning, storage layers, hardware failure modes — experience that doesn't come from running managed services alone.
Architecture you can defend
Every workload placement, every trade-off, documented with its reasoning. Your auditors and your future hires will both thank you.
No outsourced ticket queue
The engineers who built your platform are the ones on call for it. Context is never lost in a handoff.

After the migration
Patching & upgrades
Kubernetes versions, OS patches and CVE response — handled, tested, rolled out.
Proactive monitoring
We page ourselves before your users notice. Incident response under SLA.
Managed deployments
Your developers ship; we keep the path to production safe and fast.
Capacity & performance
Continuous right-sizing of the platform as your workloads evolve.
Security reviews
Periodic reviews of access, policies and exposure — with findings you can act on.
No lock-in, ever
Everything is documented and in your repos. If we part ways, you keep a platform your team can run.

In plain terms
Atlansec migrates Kubernetes workloads from public cloud to private hardware or European data centres in four phases. First, our engineers map the existing environment — workloads, data flows, network topology and dependencies — and write it up as an architecture document. Second, the target platform is built in parallel: cluster, networking, GitOps delivery with Argo CD, Prometheus and Grafana observability, and Velero backups — while production keeps running untouched. Third, workloads are cut over with a rehearsed strategy and rollback available at every step; no big-bang weekend windows. Fourth, the platform moves into SLA-backed operations run by the same engineers who built it. Every piece of configuration lives in your own version control from day one, so there is no lock-in and nothing hidden — the result is a platform you own outright, on infrastructure whose cost is fixed and whose data residency you can audit.
After cutover, Atlansec operates the platform under a defined SLA — the same infrastructure and network engineers who designed it, not an outsourced ticket queue. Day to day that means 24/7 monitoring, patching and upgrades, capacity planning, backup verification, and incident response with agreed P1/P2/P3 targets. You keep full administrative access and ownership; nothing is a black box. Because the whole platform is defined in version-controlled GitOps manifests, every change is reviewable and reversible, and you can take operations in-house whenever you choose — the knowledge and configuration are already yours. Reporting stays plain and honest: what changed, what was patched, and what (if anything) broke and why. The goal is a quiet platform that simply runs, so your team spends its time on the product instead of keeping the lights on.
A 30-minute conversation with an engineer — not a salesperson. You leave with an honest read on whether on-premise makes sense for you, and what the path would look like.
