Kubernetes & Cloud-Native Platform Architecture
I design Kubernetes platforms as production infrastructure: secure, observable, GitOps-driven, and ready for multi-tenant growth. Not just cluster maintenance.
- Production Kubernetes
- GitOps (Argo CD)
- Istio Service Mesh
- Ingress → Gateway API
- Observability
- Multi-tenant & Multi-cluster
Problems
When Kubernetes Becomes a Risk Instead of a Platform
Kubernetes problems are rarely about Kubernetes itself. They come from missing platform boundaries: unclear ownership, weak delivery discipline, and inconsistent security and observability.
Fragile deployments
Releases are stressful: configuration drift, differences between environments, manual changes, and uncertain rollbacks.
Ingress and policy sprawl
Auth, rate limits, and routing rules live in different places, which makes edge security hard to manage.
Low visibility
There are no reliable signals across workloads: traces, golden metrics, SLOs, and alerts someone can act on.
Scaling pain
Tenant isolation, multi-cluster expansion, and operational maturity weren't designed in from day one.
Deliverables
What I Deliver
An implementable platform architecture: patterns, boundaries, and a rollout plan that reduce operational risk and speed up delivery.
01
Production Platform Foundations
A cluster baseline that is secure, scalable, and maintainable.
Includes
- Cluster strategy (single vs. multi-cluster) and environment topology
- Identity, RBAC, and namespace and tenant isolation model
- Resource governance: quotas, limits, and admission policies
- Upgrade strategy and operational readiness baseline
02
GitOps Delivery & Environment Strategy
Deployments become predictable, repeatable delivery workflows.
Includes
- Argo CD architecture and repository structure
- Promotion workflows: dev → staging → prod
- Secrets strategy and configuration boundaries
- Release discipline and rollback strategies
03
Traffic, Ingress & Gateway Modernization
Ingress treated as a control plane for security, compliance, and developer experience.
Includes
- Ingress controller strategy and migration planning
- Gateway API adoption path, where it fits
- Placement of rate limiting, auth, routing, and policies
- Clear boundary between external and internal traffic
04
Service Mesh & East–West Security
Mesh capabilities introduced with clear responsibilities and measurable outcomes.
Includes
- Istio design, including ambient or sidecar mode where relevant
- mTLS and policy enforcement boundaries
- Service-to-service access control
- Traffic shaping and resilience patterns
05
Observability & Reliability Baseline
Reliability that is measurable and actionable.
Includes
- Integrated metrics, logs, and tracing
- SLOs and error budgets for critical services
- Alert hygiene and actionable dashboards
- Incident readiness and postmortem feedback loops
Engagement
Engagement Models
Most teams start with a platform architecture sprint, then continue with advisory support or implementation oversight.
2–4 weeks
Platform Architecture Sprint
An assessment of the current state, a target platform design, and a rollout plan.
OutputPlatform blueprint, standards, and migration plan
Ongoing
Advisory Retainer
Support while your team implements and evolves the platform safely.
OutputReviews, decisions, guardrails, and governance
Through delivery
Implementation Oversight
Hands-on supervision that reduces risk during migrations and critical platform upgrades.
OutputAligned execution, quality gates, and lower risk
FAQ
Frequently Asked Questions
Is this Kubernetes administration?
No. Administration is day-to-day operations. This is platform architecture: designing the foundations, boundaries, and delivery workflows that make operations predictable and scalable.
Do you work with specific clouds?
Yes. I commonly work with managed Kubernetes such as AKS, cost-efficient providers such as Hetzner and OVH, and hybrid setups. The design is provider-aware, not provider-locked.
Can you help migrate from an old ingress controller?
Yes. Ingress is often a security and governance layer, so migration planning covers policy mapping, compatibility checks, rollout strategy, and reducing the risk of regressions.
Do you implement the platform?
Yes, when needed. My default role is architecture leadership, but I work hands-on to unblock critical infrastructure, speed up delivery, or guide complex migrations. Implementation always follows a defined architecture, not ad-hoc fixes.
