Legacy applications are holding your business back.
Applications built a decade ago were designed for a different world — on-premises servers, manual deployments, and teams that didn't move fast. Today's business demands continuous delivery, cloud scalability, and security by default.
Modernising doesn't mean rewriting everything from scratch. Onel helps you make the right call for each application — whether that's a simple re-host, a code refactor, a re-architecture, or a full rebuild — then builds the DevOps practices that keep your team delivering fast, safely, forever.
Releases take weeks, not hours
Manual deployments, no automated testing, and fear of breaking production mean changes are batched, delayed, and risky.
High cost to maintain legacy code
Undocumented, tightly-coupled monoliths that no one wants to touch — consuming disproportionate developer time just to keep the lights on.
Applications that can't scale
On-premises apps designed for fixed capacity that fall over during peak demand, requiring manual intervention and emergency fixes.
Security gaps in delivery pipelines
No automated security scanning, hardcoded secrets, unpatched dependencies, and no visibility into what's running in production.
No visibility across the app portfolio
Applications managed inconsistently — different tools, different processes, no standard for versioning, testing, or deployment.
What Onel delivers.
From assessing your application portfolio through to running your CI/CD pipelines — Onel covers the full modernisation and DevOps lifecycle.
Application Portfolio Assessment
A structured review of your application portfolio — mapping dependencies, assessing technical debt, scoring cloud readiness, and recommending a modernisation strategy for each application using the 6R framework.
- Application and dependency mapping
- Technical debt and risk assessment
- Cloud readiness scoring per application
- 6R recommendation for each app
- Prioritised modernisation roadmap
Application Lifecycle Management (ALM)
Establishing proper ALM practices ensures every application has a clear lifecycle — from requirements and development through to testing, deployment, and retirement. Onel implements ALM frameworks that give your team visibility and control.
- ALM toolchain setup (Azure DevOps / Jira)
- Branch strategy and code review process
- Environment promotion workflow (dev → test → UAT → prod)
- Release management and change governance
- Application versioning and changelog standards
CI/CD Pipeline Engineering
Onel designs and builds CI/CD pipelines that automate the full delivery chain — from code commit through build, test, security scan, and deployment. No more manual steps, no more fear of deployments.
- GitHub Actions, Azure Pipelines, or GitLab CI
- Automated unit, integration, and regression testing
- Security scanning — SAST, DAST, dependency checks
- Container image build and registry push
- Blue/green and canary deployment strategies
Containerisation & Kubernetes
Containerising applications makes them portable, consistent, and cloud-ready. Onel containerises your applications with Docker and orchestrates them on Kubernetes — whether that's Azure AKS, AWS EKS, or on-premises.
- Docker image design and optimisation
- Kubernetes cluster design and deployment
- Azure AKS and AWS EKS managed clusters
- Helm chart development for application packaging
- Ingress, service mesh, and network policy
Code Refactoring & Re-architecture
Platform migration alone doesn't fix bad code. Onel's engineers work alongside your development team to refactor legacy codebases — reducing technical debt, improving maintainability, and making applications cloud-native.
- Legacy code review and refactoring
- Monolith decomposition into services
- API-first design and implementation
- Database modernisation (SQL 2016 → 2025, managed PaaS)
- Twelve-factor app principles implementation
AI-Assisted Development
AI coding tools have fundamentally changed how software is built. Onel helps your team adopt and get maximum value from AI development tools — increasing output quality and speed without increasing headcount.
- GitHub Copilot rollout and prompt engineering training
- Claude Code for complex refactoring and codebase analysis
- AI-assisted code review and test generation
- Guardrails and governance for AI-generated code
- Developer upskilling and AI tooling workshops
Every release automated, every step validated.
The Onel standard CI/CD pipeline covers every stage from code commit to production — with security checks and quality gates at every step.
Every stage has automated quality gates — a failed test, a high-severity security finding, or a policy violation stops the pipeline before bad code reaches production. Deployments only proceed when all gates pass. Manual approval steps can be added at any stage for compliance or change management requirements.
The 6Rs — the right move for every application.
Not every application should be modernised the same way. Onel uses the 6R framework to assess each application individually and recommend the approach that delivers the best business outcome.
Rehost
Move the application to cloud infrastructure with minimal changes — same code, same architecture, just running on cloud VMs instead of on-premises servers.
Replatform
Make targeted optimisations during the move — switch from self-managed database to a managed PaaS service, or move from a VM to a container — without changing the core application.
Refactor
Redesign and rewrite parts of the application to take full advantage of cloud-native capabilities — breaking monoliths into services, adopting APIs, or implementing event-driven patterns.
Repurchase
Replace the application entirely with a commercial SaaS product — moving from a custom-built or on-premises system to a cloud-native equivalent (e.g. move to Salesforce, ServiceNow, or Microsoft 365).
Retain
Some applications are not worth migrating right now — whether due to compliance constraints, recent investment, or end-of-life timeline. Retain them on-premises and revisit in a future cycle.
Retire
Identify and decommission applications that are no longer used or have been superseded — freeing up resources, reducing attack surface, and eliminating maintenance burden.
Cloud-native application delivery at scale.
Containers and Kubernetes are the foundation of modern application delivery — enabling consistent environments, automated scaling, and fast, reliable deployments across any cloud or on-premises platform.
Containerisation with Docker
Onel packages your applications into optimised, minimal Docker images — ensuring consistency between development, test, and production environments, eliminating "works on my machine" problems.
Kubernetes Cluster Design & Deployment
We design and deploy AKS or EKS clusters sized for your workloads — with node pools, autoscaling, network policies, and RBAC configured from day one.
Helm Charts for Application Packaging
Application configuration is packaged as Helm charts — making deployments repeatable, parameterised, and version-controlled. Promoting between environments is a single command.
Observability — Prometheus, Grafana & Azure Monitor
Full cluster and application observability — metrics, logs, traces, and alerting — so your team always knows what's happening in production and can respond before users notice.
Kubernetes Security Hardening
Network policies to limit pod-to-pod communication, Pod Security Standards, RBAC for team access, secrets management via Azure Key Vault, and container image vulnerability scanning baked into the pipeline.
GitOps with ArgoCD or Flux
Infrastructure and application state is driven by Git — changes to the repository automatically reconcile to the cluster. Drift detection and automated self-healing keep your cluster in its desired state.
Security embedded — not bolted on at the end.
Security that's added after development is expensive to fix and easy to miss. DevSecOps embeds security checks into every stage of the delivery pipeline — automatically catching vulnerabilities before they reach production.
Static Code Analysis (SAST)
Every commit is scanned for security vulnerabilities in the code itself — SQL injection, XSS, insecure functions, and hardcoded secrets — before the code is even built.
Dependency & Container Scanning
Open source libraries and container base images are scanned for known CVEs with every build — blocking deployments that introduce high-severity vulnerabilities from third-party packages.
Dynamic Testing (DAST)
Running applications are probed for vulnerabilities — testing actual HTTP responses for injection flaws, authentication weaknesses, and misconfigurations that only appear at runtime.
Secrets Management
No credentials in code, ever. Secrets are stored in Azure Key Vault or HashiCorp Vault and injected at runtime — with automatic rotation and audit logging of every access.
Policy as Code
Security and compliance policies are codified and enforced automatically — ensuring deployed resources always comply with your standards, with violations blocked before they reach the cluster.
Supply Chain Security (SBOM)
Software Bill of Materials (SBOM) generated for every build — providing a complete inventory of all components, libraries, and versions included in every release for vulnerability tracking and compliance.
