The project
Nimbus ran fragile, expensive infrastructure with manual deployments. They needed reliability, automation and a lower bill.
The challenge
Frequent downtime, manual releases and runaway cloud cost were holding the business back. There was little visibility when things broke.
Our solution
We re-architected on AWS with infrastructure-as-code, containerized workloads on Kubernetes, automated GitOps deployments, and full observability — then optimized cost.

Architecture
Kubernetes + GitOps + observability
How it came together
Business problem
Fragile, expensive, manually-deployed infrastructure with poor visibility.
Research
We assessed the architecture, cost drivers and failure modes.
Strategy
IaC + Kubernetes + GitOps + observability, migrated with rollback at every step.
Design process
Internal dashboards and actionable alerting the team would actually use.
Development
Terraform modules, containerized workloads, GitOps pipelines.
Testing
Staged migration with load and failover testing.
Deployment
Incremental cutover with zero-downtime and full monitoring.
Results
40% cost cut, 3× reliability, deploys from hours to minutes.
Lessons learned
Observability first made every later optimization obvious.
- Internal dashboards for deploys and health
- Clear, actionable alerting
- Self-service runbooks for the team
Reproducible infrastructure in Terraform, workloads on EKS, GitOps deployments via ArgoCD, and metrics/logs/traces in Grafana for real-time insight.
Deploys went from hours to minutes, downtime fell sharply, and the cloud bill dropped 40%.
