Reference architectures for production platforms

Educational and anonymized. Each diagram is labeled “Reference architecture—not a universal prescription.” Use them to frame design reviews — not as copy-paste mandates.

platform

Production AKS Platform

Reference architecture—not a universal prescription.

arch@bcd:~ — production-aks-platform

# Click a layer for context · drag to reorder · reset path

$ inspect edge

1/6

Edge security

DNS, CDN, WAF/DDoS posture, and Application Gateway/Ingress entry.

Problem it solves

AKS clusters are created quickly but lack clear edge, platform, workload, data, and observability boundaries.

When to use it

When introducing or hardening Azure Kubernetes Service for production workloads.

Main design decisions

  • ›Separate system and user node pools
  • ›Least-privilege RBAC and network policies
  • ›Progressive delivery with health-gated rollouts
  • ›Managed data services outside the cluster where appropriate

Failure modes and controls

  • ›Noisy-neighbor workloads without pool isolation
  • ›Over-permissive RBAC
  • ›Missing rollback when ingress or deploy health fails
  • ›Blind spots without Azure Monitor/SIEM integration

Deliverables BetterCallDevOps can provide

  • ›AKS reference design notes
  • ›Hardening checklist
  • ›Ops runbook outline

delivery

Secure CI/CD Delivery

Reference architecture—not a universal prescription.

arch@bcd:~ — secure-cicd-delivery

# Click a layer for context · drag to reorder · reset path

$ inspect dev

1/5

Developer change

Branch and pull request as the unit of change.

Problem it solves

Delivery speed without security gates and approval boundaries creates avoidable production risk.

When to use it

When modernizing Jenkins/GitLab pipelines for safer, reviewable releases.

Main design decisions

  • ›Put scanning on the path that actually ships
  • ›Separate build provenance from environment promotion
  • ›Require approvals before production
  • ›Pair progressive deploy with telemetry and rollback

Failure modes and controls

  • ›Optional gates in production paths
  • ›Secrets in pipelines
  • ›No health-gated rollback
  • ›Approval theater without ownership

Deliverables BetterCallDevOps can provide

  • ›Pipeline reference design
  • ›Gate/approval matrix
  • ›Rollback playbook

reliability

SRE Reliability and Uptime Process

Reference architecture—not a universal prescription.

arch@bcd:~ — sre-reliability-process

# Click a layer for context · drag to reorder · reset path

$ inspect define

1/4

Define

User journey → SLI/SLO definition.

Problem it solves

Teams alert on everything or nothing without a reliability operating loop.

When to use it

When introducing SLO practice, incident readiness, and corrective-action discipline.

Main design decisions

  • ›Start from user journeys, not host metrics alone
  • ›Define SLIs/SLOs before expanding alert volume
  • ›Treat RCA as a learning loop, not blame
  • ›Review error budgets and capacity deliberately

Failure modes and controls

  • ›Alert fatigue
  • ›No rollback/mitigation path
  • ›RCA without corrective action tracking
  • ›Uptime claims without measurement

Deliverables BetterCallDevOps can provide

  • ›SLO worksheet
  • ›Incident/RCA templates
  • ›Reliability review cadence

Glossary

  • MTTD: Mean Time To Detect — how quickly impact is noticed.
  • MTTR: Mean Time To Recovery — how quickly service is restored.
  • Error budget: Allowed unreliability derived from an SLO.
  • RPO: Recovery Point Objective — acceptable data loss window.
  • RTO: Recovery Time Objective — acceptable downtime window.

Vulnerability Management Lifecycle

Reference architecture—not a universal prescription.

arch@bcd:~ — vulnerability-management

# Click a layer for context · drag to reorder · reset path

$ inspect inventory

1/5

Inventory

Asset inventory and in-scope systems.

All security testing, scanning, exploitation validation, and production changes are performed only with written authorization and an agreed scope.

Problem it solves

Scan reports pile up without ownership, SLAs, validation, or evidence.

When to use it

When building an authorized, repeatable vulnerability remediation program.

Main design decisions

  • ›Authorization before scanning
  • ›Normalize and prioritize findings
  • ›Assign owners and SLAs
  • ›Close with validation evidence or accepted risk

Failure modes and controls

  • ›Unauthorized testing
  • ›Critical findings without owners
  • ›Patches without retest
  • ›Accepted risk without expiry/review

Deliverables BetterCallDevOps can provide

  • ›Remediation workflow
  • ›Tracker model
  • ›Evidence pack outline

migration

Cloud Migration Method

Reference architecture—not a universal prescription.

arch@bcd:~ — cloud-migration-method

# Click a layer for context · drag to reorder · reset path

$ inspect discover

1/5

Discover

Applications, dependencies, data, traffic.

Problem it solves

Migrations fail when discovery, classification, pilots, and rollback are skipped.

When to use it

When planning Azure↔AWS moves or significant landing-zone transitions.

Main design decisions

  • ›Inventory before design
  • ›Classify rehost/replatform/refactor/retire/retain
  • ›Pilot before waves
  • ›Validate performance, security, backup/DR, and rollback

Failure modes and controls

  • ›Unknown dependencies
  • ›Big-bang cutover
  • ›No rollback
  • ›Optimizing only after painful go-live

Deliverables BetterCallDevOps can provide

  • ›Discovery/assessment pack
  • ›Wave plan
  • ›Pilot validation checklist

automation

On-Demand Automation Lifecycle

Reference architecture—not a universal prescription.

arch@bcd:~ — automation-lifecycle

# Click a layer for context · drag to reorder · reset path

$ inspect measure

1/4

Measure toil

Frequency, effort, and risk of the manual task.

Problem it solves

Scripts accumulate without measuring toil, approvals, or failure paths.

When to use it

When replacing recurring manual work with governed automation.

Main design decisions

  • ›Automate only after measuring frequency/effort/risk
  • ›Define permission and audit boundaries
  • ›Require failure-path tests
  • ›Observe outcomes after deploy

Failure modes and controls

  • ›Automating the wrong task
  • ›Over-privileged bots
  • ›No audit trail
  • ›Silent failure in production

Deliverables BetterCallDevOps can provide

  • ›Automation discovery map
  • ›POC with approval/audit path
  • ›Ops and observability notes
