01
CI/CD pipeline architecture
Complete delivery workflows on Azure DevOps, GitLab CI, Jenkins and GitHub Actions - branching strategy, quality gates, artefact promotion and automated release management.
Cloud infrastructure that holds under load.
CloudSphere is a cloud infrastructure and DevOps engineering practice. We design delivery pipelines, run Kubernetes in production, and codify environments across AWS and Azure - for teams where downtime and cloud spend both carry a real number.

Teams we have worked with
What we deliver
Cloud & DevOps engineering
End-to-end work across the cloud lifecycle - from the first pipeline to infrastructure that survives its third year in production.
02
Kubernetes & containers
EKS and AKS cluster design, GitOps delivery with ArgoCD, Helm chart authoring, and containerisation of existing applications - with the scaling and failure behaviour worked out before go-live.
03
Infrastructure as Code
Reproducible, version-controlled environments built with Terraform, Ansible and CloudFormation. Modular templates, remote state, and a review path so infrastructure changes go through the same rigour as application code.
04
DevSecOps & security automation
Shift-left security wired into the pipeline - dependency and image scanning, IAM and RBAC hardening, compliance checks, and secrets handling that does not depend on people remembering.
05
Monitoring & observability
Metrics, logs and traces that answer real questions - Prometheus, Grafana and the ELK stack, with SLO/SLI dashboards and alerting tuned so the on-call rotation stays survivable.
06
Migration & cost optimisation
Moving workloads onto AWS or Azure without a rewrite, then taking the bill apart line by line. Right-sizing, storage tiering, and removing the services nobody remembers switching on.
Platforms & tooling
What we work in
We hold opinions about these, but not religious ones. The right tool is usually the one your team can still operate in eighteen months.

Where we have delivered
Engagements are described by sector and outcome. Client names and specifics stay confidential unless we have written permission to share them.
DevOps strategy and delivery platform for a US engineering team
We led the DevOps architecture for a distributed product team, replacing ad-hoc deployments with governed pipelines and building automation for a Microsoft Fabric data estate.
- Complete CI/CD build-out on Azure DevOps, with team-wide branching standards, PR rules and quality gates
- Automated deployment of Fabric workspaces, OneLake and Power BI assets through the REST APIs
- In-house security scanning built to replace a SaaS scanner, cutting €500+ per month
Hybrid-cloud cost reduction across AWS and Azure
We took apart a production AWS estate that had grown organically, then rebuilt the expensive parts as reviewable Terraform while keeping the platform running.
- 90% reduction in network security spend
- 65%+ reduction in object storage cost through tiering and lifecycle policy
- €35,000+ in verified annual savings
- Infrastructure codified in Terraform and Ansible across both clouds
Compliant delivery pipelines for regulated healthcare workloads
Healthcare infrastructure has to be auditable as well as automated. We built the pipelines so that compliance evidence is a by-product of shipping rather than a separate scramble.
- Azure DevOps CI/CD for enterprise healthcare workloads
- YAML pipelines and modular Terraform for repeatable environments
- Security and compliance controls held under a strict regulatory regime
Migration to AWS with Kubernetes from a standing start
A full move off legacy hosting: infrastructure designed from scratch in Terraform, applications containerised, and the whole thing handed over with runbooks the team could actually follow.
- AWS infrastructure designed from scratch in Terraform
- Applications containerised and deployed onto EKS and AKS
- Automated deployment, monitoring and backup established
- Significant reduction in hosting cost post-migration
How we work
Assess, design, build, hand over
Every engagement is built to end well. You keep the code, the accounts and the knowledge - we are not interested in being a dependency.
01
Assess
A short, paid review of the current estate: architecture, delivery process, spend and risk. You get a written findings document whether or not we work together after it.
02
Design
A target architecture and a sequenced migration path, with the trade-offs written down. Decisions are recorded so the reasoning survives staff turnover.
03
Build
Infrastructure as code, pipelines, gates and observability - shipped incrementally against a running system, in your repositories and your cloud accounts.
04
Hand over
Runbooks, dashboards and working sessions with your engineers. We stay on retainer if that is useful, and leave cleanly if it is not.
Common questions
Before you get in touch
We are based in Croatia and work remotely. Past engagements have run across the EU, the United States and New Zealand, so overlapping working hours with distributed teams is routine rather than an exception.
Yes. We have delivered pipelines for healthcare workloads under a strict regulatory regime, and built security automation and compliance checks into delivery for energy and enterprise clients. Tell us which framework applies and we will be direct about fit.
That is the usual arrangement. We embed with your team, work in your repositories and follow your review process. Handover and knowledge transfer are part of the engagement, not an afterthought at the end of it.
No. Everything we build is Infrastructure as Code committed to your repositories, running in your cloud accounts, using standard tooling - Terraform, Kubernetes, and your existing CI platform. There is no proprietary layer to unpick if you take it in-house.
With a short call to establish whether there is a fit, followed by a paid assessment of the current estate. The assessment produces a written findings and options document that is yours regardless of what you decide next.
