Case study
Migrating a regulated workload to the cloud with zero downtime
How we moved a critical platform across environments behind a dual-write cutover — and what we would do differently.
Read moreArdeon Technologies is an end-to-end technology solutions provider. We design and operate cloud and on-prem infrastructure, harden it against real threats, turn your data into something you can trust, and ship the software that runs on top — for organisations in healthcare, logistics, retail, education and beyond.
Platforms & technologies we work with
Most providers give you one of these and leave the seams to you. We own all four — so the infrastructure, the controls on it, the data flowing through it, and the software on top are designed to fit together.
Cloud, hybrid or on-prem platforms provisioned as code and operated with real monitoring — not a wiki page and good intentions.
Practical security across identity, data, network and workload — mapped to the framework your auditors actually use.
Pipelines, warehouses and lakehouses that make your data trustworthy enough to run the business on — and to train models on.
Applications, integrations and applied AI — tested, documented, and maintainable by your own team after handover.
The craft is the same everywhere; the data, the regulator and the cost of downtime are not. We learn your context before we design.
No hand-built servers and no undocumented changes. Your infrastructure lives in version control, ships through a pipeline, and can be rebuilt from scratch on a bad day.
Terraform and OpenTofu modules with peer review, policy checks, and a clear plan before anything applies.
Encryption, least-privilege roles, private networking and secrets management baked into the module, not left to the operator.
Metrics, logs and traces wired up as the platform is built — so the first incident is not the first time you look.
Backups and disaster recovery tested on a schedule, with documented RPO and RTO you can hold us to.
# Hardened managed Kubernetes cluster module "platform" { source = "./modules/cluster" environment = "production" private_nodes = true encryption = "cmk" backup_policy = "daily-35d" # least-privilege by default rbac = { admins = var.platform_admins read_only = var.auditors } }
We are tool-agnostic and pragmatic — picking the right technology for reliability, cost, and compliance rather than for novelty.
We map your systems, data flows, and compliance obligations before writing a line of code.
Architecture, security controls, and cost model reviewed with your stakeholders and signed off.
Iterative delivery with automated testing, peer review, and continuous integration throughout.
Monitoring, documentation, runbooks, and knowledge transfer so your team stays in control.
We contribute to and maintain open-source tooling, and we build on open standards — because the platform you pay for should not become a cage. Our libraries, modules, and templates are free to use and extend.
You talk to the people doing the work. We have run production systems under audit and under load, and we would rather tell you the unglamorous answer than sell you the exciting one.
Encryption, audit trails, and least-privilege access on every build — whichever framework applies to you.
Open standards and open-source foundations keep you in control of your data, your costs, and your roadmap.
Documentation, runbooks, and training so your team owns the outcome — not just the code.
Practical guidance on infrastructure, security, and getting software and AI into real use.
