Cloud done properly.
Built. Automated. Managed.
Moving to the cloud is straightforward. Making it secure, cost-efficient, and operationally sustainable is where most organisations struggle. Onel designs, builds, and manages cloud environments — with Infrastructure as Code from day one and ongoing managed support once you're live.
Infrastructure as a Service (IaaS)
Azure, AWS, and hybrid cloud — compute, storage, and networking in the cloud
Infrastructure as Code
Terraform, Bicep, and Ansible — repeatable, version-controlled infrastructure
Cloud Migration
Structured migration from on-premises to cloud — with zero surprises
Managed Cloud Support
24/7 monitoring, cost governance, and ongoing cloud operations
Microsoft 365 & Security
M365, Purview, Defender, Intune, Entra ID & Sentinel
The right cloud model for your business.
Not every workload belongs in the same place. Onel helps you decide what should run where — and builds and manages it accordingly.
Public Cloud (IaaS)
Compute, storage, and networking consumed from Azure or AWS — on demand, at scale, billed monthly.
- Azure Virtual Machines, Azure VMware Solution
- Azure Virtual Network, ExpressRoute, VPN Gateway
- Azure Blob / Files / Managed Disks storage
- AWS EC2, VPC, S3, EBS equivalents
- Platform services — Azure SQL, App Service, AKS
- Cost management and right-sizing governance
Hybrid Cloud
On-premises infrastructure connected to public cloud — workloads running where they make the most sense.
- Azure Arc — manage on-prem servers from Azure
- Azure ExpressRoute — private, dedicated cloud connectivity
- Site-to-site VPN with failover and redundancy
- Unified identity via Microsoft Entra ID (Azure AD)
- Hybrid backup — on-prem and cloud retention tiers
- Consistent security policies across both environments
Private Cloud
Dedicated infrastructure at Australian data centres — cloud operating model, your own hardware.
- HPE GreenLake — consumption-based on your premises
- Azure VMware Solution — VMware in Azure datacentres
- Onel Managed Private Cloud — dedicated hosting
- Data sovereignty — data never leaves your control
- Consistent management via Azure Arc or Intersight
- Suitable for regulated workloads and sensitive data
Every environment built in code.
Never clicked together manually.
Manual cloud configuration is fragile, undocumented, and impossible to repeat. Onel deploys all cloud infrastructure using Infrastructure as Code — so every environment is consistent, version-controlled, and can be rebuilt in minutes.

Version-Controlled Infrastructure
All infrastructure lives in a Git repository — every change is tracked, reviewed, and auditable. Roll back to any previous state in minutes if something goes wrong.
Consistent, Repeatable Environments
Dev, test, staging, and production are built from the same codebase — no more "works in dev but not in prod" caused by manual configuration drift.
Automated CI/CD Pipelines
Infrastructure changes go through an automated pipeline — plan, validate, approve, apply. No one manually logs into the Azure portal and changes production settings.
Security and Policy Baked In
Security controls, tagging policies, NSG rules, and RBAC assignments are all defined in code — enforced automatically on every deployment, not added as an afterthought.
Self-Documenting Infrastructure
The code is the documentation. New team members can read the Terraform modules and understand exactly what's deployed — no out-of-date wiki pages to chase.
Handed Over to Your Team
At the end of the engagement, Onel hands over the full IaC codebase, pipeline configuration, and documentation — your team owns and can maintain it going forward.
A structured path to cloud — no shortcuts.
Cloud migrations that fail do so because they skip steps. Onel follows a structured five-phase methodology that ensures every workload lands correctly and runs well after go-live.
Assess & Discover
Inventory all workloads, map dependencies, assess cloud readiness, and identify what to migrate, modernise, or retire.
Design & Plan
Cloud architecture design, IaC module structure, network topology, security baseline, and detailed migration wave plan.
Build & Automate
Deploy landing zone via IaC, build CI/CD pipelines, configure identity and security policies, validate environment.
Migrate & Cutover
Wave-based workload migration, cutover window management, post-migration validation, and rollback rehearsal.
Operate & Optimise
24/7 managed cloud services, cost optimisation, security monitoring, patching, and continuous improvement.
End-to-end cloud capability.
From initial strategy through to day-two operations — Onel covers the full cloud services lifecycle.
Cloud Readiness Assessment
A structured review of your current environment — workload inventory, dependency mapping, cloud readiness scoring, cost modelling, and a prioritised migration roadmap.
- Application and infrastructure discovery
- Dependency mapping and compatibility analysis
- Total cost of ownership (TCO) modelling
- Prioritised migration wave plan
Cloud Landing Zone Design
An Azure or AWS landing zone is the foundation all your workloads will run on. Onel designs and deploys a secure, scalable landing zone using IaC — with identity, networking, security, and governance built in from day one.
- Azure Landing Zone / AWS Control Tower
- Hub-and-spoke or Virtual WAN network topology
- Identity and RBAC design (Microsoft Entra ID)
- Security baseline — Defender for Cloud, policies
- Fully deployed via Terraform or Bicep
IaaS Deployment
Virtual machines, virtual networks, load balancers, storage accounts, and all supporting infrastructure — deployed, configured, and tested via IaC, ready to run your workloads.
- Azure VMs, VMSS, Azure VMware Solution
- Virtual networks, NSGs, route tables
- Azure Files, Blob, Managed Disks storage
- Load balancing and traffic management
- Azure Backup and Site Recovery
Infrastructure as Code
Every environment Onel builds is deployed using Infrastructure as Code — Terraform, Azure Bicep, or Ansible depending on your stack. Repeatable, version-controlled, and handed over to your team at project close.
- Terraform modules for Azure and AWS
- Azure Bicep for native Azure deployments
- Ansible for configuration management
- CI/CD pipelines via GitHub Actions or Azure DevOps
- State management and drift detection
Cloud Migration
Structured wave-based migration of workloads from on-premises to cloud. Onel manages the full process — from pre-migration testing through to cutover and post-migration validation.
- Azure Migrate and AWS Migration Hub tooling
- Wave-based cutover planning and execution
- Data migration and replication management
- Post-migration validation and optimisation
- Rollback planning for every wave
Hybrid Connectivity
Azure ExpressRoute, site-to-site VPN, and Azure Virtual WAN — designed and deployed so your on-premises environment and cloud environment work as a single, unified network.
- Azure ExpressRoute design and provisioning
- Site-to-site VPN with BGP failover
- Azure Virtual WAN for multi-site connectivity
- Private DNS and DNS resolution across hybrid
- Azure Arc for unified on-prem/cloud management
Cloud managed services that keep working.
Going live is the beginning, not the end. Onel's cloud managed services cover everything from day-to-day monitoring through to cost governance and continuous improvement.

| P4 — Low (advice/change) | 8 business hrs | 40 business hrs |
What's included in Cloud Managed:
Cloud costs can spiral without active governance. Onel's FinOps practice monitors your spend in real time, identifies wasted or over-provisioned resources, implements right-sizing, and provides monthly cost attribution reports by workload and business unit.
Microsoft 365 — deployed, secured, and governed.
Microsoft 365 is far more than email and Teams. Deployed correctly, it is a complete productivity, security, identity, and compliance platform. Onel designs, implements, and manages M365 environments — from initial tenant setup through to advanced security and data governance.
We work across all major cloud platforms.
Onel's cloud engineers hold certifications across Azure, AWS, and the key IaC and DevOps toolchains.
Common cloud challenges we solve.
Starting a cloud journey
Organisations moving to cloud for the first time who want a structured, low-risk path — not a rushed migration that creates more problems than it solves.
Cloud bill running out of control
Azure or AWS spend growing faster than expected with limited visibility into what's driving costs — and no one accountable for optimisation.
Environments built manually, not in code
Cloud resources clicked together in the portal with no documentation — making changes risky, environments inconsistent, and audits painful.
Security posture gaps in the cloud
Missing security controls, overprivileged identities, exposed storage accounts, and no visibility into what's happening across the cloud environment.
Hybrid connectivity that doesn't work well
On-premises and cloud environments that feel disconnected — latency, split DNS, inconsistent security policies, and users experiencing reliability issues.
