Kubernetes on Azure for a SaaS company
We moved a growing SaaS application from one manually managed server to Azure Kubernetes Service, with zero-downtime deploys.

01
The challenge
- Manual deployments over SSH, with downtime
- No staging environment to test changes
- One server was a single point of failure
- No clear view of errors, load or costs
02
What we delivered
- Dockerfiles for each service and a private container registry
- AKS cluster defined as infrastructure as code
- CI/CD pipeline: test, build, scan and deploy on every merge
- Separate staging and production with automatic rollbacks
- Managed database with automated backups and restore tests
- Monitoring, logging and alerts, with dashboards for errors and costs
03
How we delivered
We migrated step by step: containerised first, ran staging on AKS, then moved production during a planned window with a tested rollback plan. Afterwards the team received documentation and a handover session.
