Platform Engineering
CI/CD
When most engineering teams hear ‘DevOps,’ they think pipelines — automated builds, tests, and deployments. And yes, CI/CD is foundational. But modern DevOps in 2025 is about something broader: building internal platforms that make developers fast, safe, and self-sufficient.
This shift — from DevOps as a set of tools to DevOps as a product philosophy — is what separates high-performing engineering organisations from the rest.
The evolution: from CI/CD to platform engineering
Traditional DevOps thinking treats infrastructure as a shared responsibility between developers and operations. Platform engineering takes this further: the infrastructure, tooling, and developer experience become a product, built and maintained by a dedicated team, consumed by developers as a self-service capability.
Leading technology companies — Spotify, Airbnb, Shopify — pioneered this model. The tools have now matured to the point where any serious engineering organisation can adopt it.
The Kubernetes question
Kubernetes has become the de facto standard for container orchestration. But for many organisations, running and managing Kubernetes clusters is more overhead than value. The ecosystem has evolved accordingly:
- Managed Kubernetes (EKS, AKS, GKE) handles control plane complexity
- Helm and Kustomize provide templating and environment management
- ArgoCD and Flux enable GitOps — where Git is the single source of truth for cluster state
- Crossplane extends Kubernetes to manage cloud resources declaratively
At DeepTechComputing, we’ve deployed Kubernetes environments for clients ranging from defence technology firms to e-commerce platforms. The key insight: Kubernetes is not a destination, it’s an enabling layer. What you build on top of it is what matters.
GitOps: the practice every team should adopt
GitOps is simple in principle: everything — application code, infrastructure definitions, configuration — lives in Git. Changes to production happen only through pull requests, reviewed by a human, and applied automatically by a controller running in the cluster.
The benefits are substantial:
- Full audit trail: every change is a Git commit with an author, timestamp, and message
- Easy rollback: revert a bad deployment by reverting a commit
- Drift detection: the controller continuously reconciles desired state with actual state
- Reduced blast radius: developers can’t SSH into production and make undocumented changes
Infrastructure is code. Treat it with the same discipline — reviews, testing, version control — as your application code.
Observability: the missing piece
Many teams invest heavily in deployment automation and neglect observability. This is backwards. You cannot run a reliable system you cannot see.
Modern observability rests on three pillars:
- Logs: structured, searchable records of what happened
- Metrics: quantitative measurements of system behaviour (latency, error rate, saturation)
- Traces: end-to-end records of request paths through distributed systems
Tools like Prometheus, Grafana, Jaeger, and the OpenTelemetry standard have made world-class observability accessible to teams of any size. There’s no excuse for flying blind in 2025.
Security left: shifting security into the pipeline
DevSecOps — integrating security into the development pipeline rather than applying it at the end — is no longer optional. With SAST (static analysis), DAST (dynamic analysis), container image scanning, and secrets management integrated into CI/CD, vulnerabilities are caught in development rather than production.
Our recommended toolchain: Trivy for container scanning, HashiCorp Vault for secrets management, SonarQube for static analysis, and OWASP ZAP for dynamic testing.
