Oreon Information Technology
5
(1 review)
Cloud, DevOps & SRE consultancy| reliable, observable & cost-efficient production on AWS, GCP, Azure
Oreon IT is a London-based Cloud, DevOps and Site Reliability Engineering (SRE) consultancy. We help startups, scale-ups and enterprises make production reliable, observable and cost-efficient — without slowing product teams down. Vendor-neutral and cost-aware by design, so our advice serves your architecture, not a reseller quota. What we do: • Cloud & Infrastructure — architecture, migration and cost optimisation across AWS, Google Cloud and Azure; Kubernetes platform engineering (EKS, GKE, AKS, OpenShift); hybrid/multi-cloud • Delivery & Automation — CI/CD, Infrastructure as Code (Terraform & OpenTofu), GitOps, and release automation to deploy safely and often • Reliability & Observability — SRE (SLOs, error budgets, incident response, toil reduction) and full-stack observability with OpenTelemetry, Prometheus and Grafana • Cost & Operations — cloud cost optimisation (FinOps) and managed operations with named engineers • Legacy modernisation — migrating legacy systems to the cloud with phased, reversible cut-overs How we work: Most engagements start with a short, fixed-scope diagnostic — a Cloud Cost Review, IaC Readiness Check or Infrastructure/SRE Assessment — so you get concrete findings first. From there: transformation programmes and, where it helps, ongoing managed operations. Plain technical English, explicit scope, and documentation your team can run with — no black boxes, no lock-in. Who we work with: Regulated and enterprise environments — financial services, healthcare, retail/e-commerce, mobility and SaaS. Typical work: cloud migrations, multi-tenant Kubernetes platforms, CI/CD modernisation, observability rollouts and cloud-cost reduction. Partners of Google Cloud, Elastic and DigitalOcean. 10+ years' experience · 60+ projects delivered · 20+ enterprise clients · 40+ cloud certifications. Standardising Terraform, hardening Kubernetes, cutting a cloud bill, or trying to see what production is actually doing? Start with a 30-minute call.
