Cloud Architecture 

We review more than 50 cloud architectures a year, almost all of them built by someone else. We see the same five mistakes over and over, and we know which of them are cheap to fix and which ones you inherit for the next decade.

Landing zones, target architectures and multi cloud strategies for regulated, business critical systems, including hybrid setups with your own data centres and fully air gapped environments.

What exactly is Cloud Architecture?

The decisions everything else inherits: how tenants are isolated, where identity lives, how a change reaches production, what an auditor can trace, what a workload costs to run, and what happens when a provider fails or a contract ends.

We know which of these are expensive to reverse because we run the platforms we design. The architect who draws it sits on the same team as the engineers who build it and the CloudOps team that operates it.

Architecture review based on production experience

We review 50+ target architectures a year against patterns proven under load, audit and regulation. You get prioritised findings, a remediation roadmap and a TCO model.

Multi-cloud and hybrid where it matters

We combine public cloud and on-premises where latency, regulation or data require it, with consistent identity, networking and operations across both. Air-gapped environments where required.

Landing zones and governance as code

Network, identity, policy, logging and cost controls delivered as code, with compliance built in as guardrails. Ownership across platform, application, security and CloudOps is defined from day one.

Why this holds up in production

Send Inquiry
  • We operate what we designOur CloudOps team runs the platforms our architects draw, which means the person who picks your tenancy model is the one paged when it breaks at 3 a.m. Nothing leaves our architecture practice that our own operators refused to run.
  • Highly regulated is our defaultBSI C5 for a hospital group, customs and GDPR audits for e-commerce logistics, financial regulation for an institutional trading platform. Air-gapped where required.
  • Hybrid at scaleWe have combined public cloud with customers' own data centres for critical workloads, with one identity, one network model and one operating team across both.
  • Platform choice from experienceWe run production platforms on T Cloud Public, STACKIT, Azure, GCP and AWS. We also publish what our own operations cost: the full KumoOps price list, all 31 add-ons, and the premium for EU-only 24/7 staffing are public on GitHub. Ask us what a platform costs and you get a number, not a discovery phase
  • Built to be handed overWe set up your platform and development teams alongside the architecture, so it runs without us when you want it to.

How an architecture takes shape with us

  1. Step 01

    Review

    Landscape, compliance scope, cost baseline. Findings ranked by the failures we have seen in comparable architectures.

  2. Step 02

    Target architecture and landing zone

    Tenancy, identity, network, guardrails, observability, provisioned as code. Reviewed with your security team before a workload lands.

  3. Step 03

    Reference implementation

    One real workload end to end: pipeline, policy enforcement, monitoring, runbook. Proves the design under production conditions.

  4. Step 04

    Scale out and hand over

    Your team runs it, or KumoOps does. That is our managed CloudOps service, at a fixed monthly price with incident response under 15 minutes.

Areas we support in

Public Sector

Multi-region rollouts, federated identity with existing AD, sovereign hosting where required.

Logistics & E-commerce

High-volume event processing with customs and GDPR audit trails.

Fintech & Digital Assets

Trading platforms for institutional clients with real-time transparency.

Transport & Mobility

Custom platforms with strict availability requirements and ecosystem interfaces.

Together with the iits team, we laid the foundation for a flexible, scalable, and future‑oriented IT architecture that, through the use of state‑of‑the‑art technologies such as Azure Kubernetes Services, Terraform, and Azure IoT components, provides our team with the necessary flexibility to respond to the highly dynamic requirements of an innovation project. The microservices and Infrastructure as Code statements developed are of excellent quality and demonstrate that the iits team meets the highest standards both technically and in terms of domain expertise. As a result, the production environment was set up almost fully automatically in a very short time, ensuring quality assurance while simultaneously minimizing the risks of configuration deviations. However, in addition to their high level of technical expertise, the seamless integration of the iits team into our project team deserves special mention.

What we design for.

A cloud platform is more than Kubernetes and Terraform. We design the controls, operating model and failure boundaries that determine whether it still works under load, during an audit and when something goes wrong.
