Why This Matters
Every few years, technology gives us a step-change — not a trend, not a fad, but a new baseline for how modern organizations operate.
Containers are that baseline today.
They aren't new. They aren't risky. They aren't experimental.
Their lineage goes back 40+ years — UNIX chroot in 1979, Linux containers in 2008, Docker in 2013 — and Kubernetes plus Azure Kubernetes Service (AKS) have turned them into a production-ready foundation used by nearly every digital-first company today.
For leaders, it comes down to four things: speed, consistency, portability, and resilience.
If cloud VMs standardized infrastructure, then:
- Containers standardize the application package, and
- Kubernetes standardizes how that package runs at scale
This is the next chapter of operational maturity — the one that unlocks everything else.
The Crawl, Walk, Run Journey
Crawl — Build Clarity, Confidence, and Culture
Start by creating a shared language.
A container is simply a lightweight, isolated package containing your app and its dependencies. It runs the same way everywhere — laptop, cloud, edge.
Unlike VMs, containers share the host OS kernel. This isn't just efficiency; it's operational simplicity.
Empower developers and platform engineers to up-skill faster with AI-driven tools like GitHub Copilot.
Normalize the history. Containers aren't a disruption — they're an evolution. Use the cloud VM analogy leaders already understand:
Containers don't change your application — they change how you package and run it.
Introduce OCI Early
The Open Container Initiative (OCI) is what makes containers portable and vendor-neutral. It defines:
- Image Specification
- Runtime Specification
- Distribution Specification
OCI is the USB standard of containers: build an image once, run it anywhere Kubernetes runs.
A Quick Win to Build Momentum
- Pick a small service.
- Containerize it.
- Push it to Azure Container Registry.
- Deploy it to Azure Container Apps.
Celebrate the win — visibly. Momentum is a leadership tool.

Walk — Operationalize and Widen the Circle
This is where Kubernetes enters the picture — but don't overcomplicate it. Let AKS manage the control plane and focus your energy on application consistency, not infrastructure plumbing.
Key priorities at this stage:
- Define OCI-compliant image standards
- Enforce runtime guardrails (RBAC, resource limits, network policies)
- Document a "golden path" for developers
Bring suppliers and partners along — using a story they already lived
During our cloud VM transformation, we faced the exact same resistance we see with containers today.
Teams weren't sure what needed to change. Suppliers insisted their software only ran on "physical servers." Partners sent dependency matrices longer than some design docs. Security wanted clarity before greenlighting anything. Everyone hesitated — waiting for someone else to take the first step.
And yet, everything shifted with one simple realization:
The workload didn't change — the hosting model did.
When people understood that:
- The OS was still the OS
- Security controls still applied
- Support contracts didn't break
- Applications didn't need rewriting
…fear evaporated. Confidence grew. Adoption took off.
Containers follow this story almost perfectly.
We package differently, we run more consistently, we operate at higher velocity, but the core workload logic stays the same.
When teams and suppliers understand this, adoption accelerates.
For containers today:
- Artifact: OCI image
- Runtime: Kubernetes API
- Hosting: AKS
Providing clear onboarding kits makes this transition even smoother.

Run — Scale, Govern, and Modernize
Now you're not just running Kubernetes — you're treating AKS as a product.
Focus on:
- Multiple node pools
- Autoscaling
- Policy-as-code
- Observability
- Cost transparency
- Integrated identity (Entra ID)
- Deep diagnostics (Azure Monitor)
Modernization becomes strategic:
- Replatform for quick wins
- Refactor when the ROI is clear
- Rearchitect when agility demands it
Start with Linux-based images — the ecosystem (and AKS itself) assumes Linux first.
Why Leaders Love This Approach
- Speed: Faster releases, fewer deployment surprises
- Resilience: Self-healing workloads, managed upgrades
- Portability: OCI standards eliminate lock-in fears
- Partner alignment: A shared, standardized operating model
KPIs That Actually Matter
- Lead time for changes → Target 30–50% improvement
- Change failure rate → Reduced through progressive delivery
- Cost visibility → Per service, per node pool, per pod
Next Steps
- Start with one pilot service.
- Align teams and suppliers to OCI standards.
- Upskill with Microsoft Learn and CNCF certifications.
- Join your local CNCF chapter — community accelerates everything.
