In cloud engineering, tools are easy.
Azure Application Insights. Log Analytics. Key Vault. Entra ID. ADF. Kubernetes. You name it.
But tools don’t create good architecture.
Thinking does.
Over time — across Azure landing zones, identity refactoring, incident recovery, and cost governance work — I noticed something consistent:
Senior Azure architects evaluate systems using a simple mental model.
Not documentation-heavy frameworks.
Not 40-page design templates.
Just four questions.
This article captures that framework for future reference.
The 4-Question Azure Architect Framework
You can apply this to:
- A file router
- Monitoring strategy
- Identity design
- Networking segmentation
- SaaS MVP architecture
- Even a small internal utility
1️⃣ What Happens When It Fails?
Most engineers ask:
“Does it work?”
Architects ask:
“What happens when it breaks?”
Failure-first thinking changes everything.
For example:
- If a file router crashes, is the file retried?
- If a background job fails silently, who detects it?
- If a dependency times out, does it cascade?
- If logging is disabled, can we reconstruct events?
In Azure environments, this usually translates to:
- Proper use of Azure Application Insights
- Dead-letter queues
- Retry policies
- Correlation IDs
- Alert rules
Resilience is not about uptime — it’s about recoverability and visibility.
2️⃣ Who Feels the Impact?
Not all failures are equal.
Ask:
- Is this internal tooling?
- Does it affect customers?
- Is revenue tied to it?
- Is compliance exposure involved?
For example:
If a low-risk internal service fails, default telemetry in Azure Application Insights might be sufficient.
If the system routes financial transactions or regulatory documents, monitoring maturity must increase.
Architecture maturity should match business criticality.
Over-engineering internal tools wastes cost.
Under-engineering customer-facing systems creates risk.
3️⃣ Can We Evolve This Without Rebuilding It?
This is where architecture becomes strategy.
Perfect systems don’t exist.
Evolvable systems do.
Ask:
- Can we add custom telemetry later without refactoring?
- Can we scale logging without rewriting the app?
- Can we introduce alerts without redesigning the service?
- Can we move from single-region to multi-region if needed?
Good Azure design allows layering.
For example:
- Start with default App Insights.
- Later add custom events.
- Then introduce dashboards.
- Then configure alerting rules.
- Eventually integrate with SIEM if required.
If improvement requires a rewrite, the original design was brittle.
4️⃣ Is Complexity Justified Right Now?
Azure makes it easy to add services.
It’s also easy to overspend and overbuild.
Before adding complexity, ask:
- Are we solving today’s real problem?
- Or anticipating hypothetical risk?
- Is there operational pain?
- Is the cost proportional?
This question protects teams from unnecessary engineering.
Many environments only need:
- Baseline monitoring
- Basic alerting
- Clear logging structure
Not every service needs enterprise-grade observability from day one.
Maturity should evolve with operational pressure.
Applying This to a Real Scenario
Imagine someone says:
“We just use default App Insights. We don’t go much further.”
Instead of reacting, run the framework:
- What happens when it fails?
- Who feels the impact?
- Can we evolve monitoring later?
- Is deeper observability justified now?
The answer might be:
- Baseline telemetry is fine today.
- Add lifecycle logging only if routing becomes business-critical.
- Keep architecture flexible.
That’s architect thinking.
Not reactive.
Not dramatic.
Not tool-obsessed.
Why This Framework Matters
In my experience working across Azure infrastructure, identity, DevOps pipelines, and operational recovery scenarios:
The biggest difference between mid-level engineers and senior architects is not tool knowledge.
It’s:
- Systems thinking
- Failure awareness
- Tradeoff evaluation
- Calm decision-making
Architects don’t chase perfection.
They design for evolution.
Final Thought
Cloud architecture is not about using more services.
It’s about asking better questions.
Before adding monitoring.
Before redesigning identity.
Before introducing complexity.
Ask the four questions.
They work every time.
