Case studies / Work in context
Change measured against the work that mattered.
These representative fictional examples show how platform decisions, delivery patterns and operational ownership can improve together.
A note on the examples
Specific by design.
Fictional by name.
- 01Client names and engagement details on this page are representative fictional examples, not claims about real Vantrel clients.
- 02Outcome measures are illustrative, engagement-specific results and are not guarantees of future performance.
- 03Technology context is included to make the approach concrete; actual tool choices depend on each organisation.
Engagement 01
Logistics software provider
Meridian Freight Systems
Challenge
A growing freight platform had inherited AWS accounts, duplicated CI workflows and separate operational practices across regional product lines. Teams waited on infrastructure specialists for routine releases, and controls varied between environments.
Approach
Vantrel and the client team mapped account ownership, workload dependencies and release risks before changing production pathways. We established a clearer multi-account structure, standardised identity boundaries and introduced reusable deployment patterns in waves. Existing workloads moved only after service owners had validated their runbooks and rollback routes.
Technology context
AWS Organizations, IAM Identity Center, Terraform, GitHub Actions, Amazon EKS, CloudWatch and OpenTelemetry. The final tool choices remained subject to the client’s existing contracts and operating skills.
“The most important change was that teams could explain the route to production and the guardrails around it.”Platform operations lead
Engagement 02
Regulated analytics company
Alder & Moss Health Data
Challenge
Data science workloads had accumulated overlapping access paths and inconsistent evidence. The security function needed stronger separation and clearer audit trails, while analytics teams still needed timely, repeatable environments.
Approach
We defined workload classes and trust boundaries with security, data and engineering stakeholders. IaC modules encoded baseline controls, workload identities replaced shared credentials where practical, and telemetry was connected to named owners. Audit evidence collection was tested alongside the delivery flow rather than as a separate exercise.
Technology context
AWS, Terraform, AWS IAM, AWS CloudTrail, KMS, Kubernetes, OpenTelemetry and a central log platform. Controls were reviewed against the client’s own regulatory and legal requirements.
“We could move from a policy conversation to a set of controls engineers could see and verify.”Security architecture manager
Engagement 03
Multi-brand retailer
North Quay Commerce Group
Challenge
Independent brand teams used different release conventions and depended on a small central operations group for routine environment work. Release coordination grew fragile during seasonal peaks, and useful platform patterns were hard to find.
Approach
The engagement started with developer interviews and release-path mapping. The team then established reusable repository templates, environment provisioning workflows and a service catalogue, piloting with two brands before extending the path. Ownership and platform feedback were built into the operating model.
Technology context
Google Cloud, GitHub Actions, Terraform, GKE, Backstage, Argo CD and Grafana. Integration choices followed the retailer’s internal security and operations standards.
“Self-service worked because the supported path reflected how our product teams release, not how an infrastructure diagram looks.”Director of engineering enablement
