CLOUD
Build a cloud foundation that scales with you
We design, migrate, and optimise cloud environments that are stable, efficient, and easy to operate.
This isn’t just your business.
It’s your legacy.
What we deliver
Modern cloud infrastructure that’s clear, maintainable, and ready to scale.
Architecture review and redesign
We assess what’s in place, identify risks and inefficiencies, and restructure your environment for clarity and control.

Our Roadmap
How we work
We start with architecture diagrams, not assumptions
Every engagement begins with a current-state review and proposed target architecture—mapped by VPC, subnets, security groups, IAM roles, and resource dependencies. We’ll flag misconfigurations, open ports, overly permissive policies, and naming inconsistencies.

We codify every change
All infrastructure is version-controlled. We use module-based Terraform structures, remote state backends, and deploy via CI pipelines. You’ll never lose track of what changed, when, or why.

We implement least-privilege IAM and role isolation by default
Access is always scoped to the smallest possible surface. We configure IAM policies, STS assume-role access, and separate staging/prod environments with distinct root accounts or organisational units.

We integrate native monitoring tools before go-live
We don’t “add” monitoring later. You’ll have CloudWatch dashboards, budget alarms, log groups, and metrics for each service out of the gate.

Optional Add-Ons
Production-readiness checklist and automated validation
We’ll verify backup policies, environment parity, tag coverage, and open ports—automatically—before go-live.

Kubernetes setup with sensible defaults
We configure EKS or AKS clusters with managed node groups, OIDC IAM roles, Helm-based deployments, and horizontal pod autoscaling. No YAML sprawl.

Developer onboarding and environment handover
We create minimal reproducible onboarding flows (e.g. devcontainer, Docker Compose, AWS SSO) and run handover sessions with your team.
