CLOUD & DATA PLATFORMS

Build a foundation
your team can operate.

Cloud & Data Architecture Review

A bounded review of one cloud or data workload: its environments, data flows, access boundaries, and operating responsibilities. Led by Ian Booker, drawing on prior Azure foundations with Terraform and enterprise data architecture work involving Snowflake.

WHEN THIS HELPS

A growing platform.
Unclear foundations.

An Azure or Snowflake initiative is ready for its next workload, but environments differ, access decisions are hard to explain, or ownership is split across teams. Make the platform changes and delivery sequence explicit before extending it.

A bounded starting point

One workload and agreed environments, reviewed through architecture documents, infrastructure definitions, and stakeholder discussions.

What you receive

  • A platform and data-flow map.
  • Prioritized architecture gaps and evidence limits.
  • A target design and decision records.
  • Operating responsibilities and a sequenced delivery plan.

The decision: which platform changes are necessary, and how should delivery be sequenced?

ILLUSTRATIVE REVIEW EXCERPT

See the reasoning.
Inspect the output.

Fictional scenario. Not a client case study. All systems, evidence references, findings, and responsibilities below are invented to demonstrate the work product. No production outcome or measured improvement is claimed. This excerpt is not the complete contracted review.

The question

A fictional organization wants to move a reporting workload from a pilot into routine operation. Azure hosts its ingestion jobs; Snowflake holds the reporting data. The team needs to decide whether its environment and access arrangements are ready for the next release.

Review boundary: One reporting workload across development and production. This excerpt examines configuration, deployment responsibility, and access to the reporting data. It does not assess the organization's entire cloud estate or certify security, compliance, cost savings, or recovery capability.

01 / Workload and environment boundaries

Development environmentAzure ingestion job → development reporting data in SnowflakeSynthetic test inputs; release validation
Production environmentAzure ingestion job → production reporting data in SnowflakeOperational inputs; business reporting
Changes cross a separate boundary

Reviewed infrastructure definitions and data-platform changes are promoted through an agreed release process. This is change promotion, not a flow of production data into development.

Fictional arrangement. Actual account, network, identity, and deployment boundaries would be established from the customer's evidence. No direct connection or shared identity between these environments is assumed.

02 / Findings and evidence limits

F01 / CONFIGURATION CONSISTENCY

The declared setup may not match the deployed one.

Fictional evidence E1: A sample change log describes a manual production configuration edit that is absent from the supplied infrastructure definition.

Inference: There is an unreconciled difference. The record alone does not establish which configuration is correct or authorize overwriting production.

Verify: Compare approved definitions with a sanitized current-state export. Have the platform owner explain and reconcile the difference before the next change.

F02 / ACCESS BOUNDARIES

The reporting task needs a defined identity.

Fictional evidence E2: A sample access matrix gives a reporting automation identity the same listed permissions as a developer role, without a task-level rationale.

Inference: The intended access boundary is unclear. The matrix is not proof of effective permissions or unauthorized access.

Verify: Map required reads and writes, inspect the relevant grants, and test intended allowed and denied actions using synthetic data in an approved environment.

F03 / OPERATING RESPONSIBILITY

A successful deployment is not an operating plan.

Fictional evidence E3: A sample release checklist names the deployment owner but omits responsibility for stale reporting data and failed refreshes.

Inference: Ongoing response and escalation are undocumented. No incident-response or availability result has been measured.

Verify: Agree who detects, investigates, and resolves each failure. Rehearse a synthetic refresh failure with the platform and reporting owners.

03 / SAMPLE ARCHITECTURE DECISION · ADR-CD-001

Establish a workload baseline before expanding production use.

Status: Proposed within this fictional scenario; subject to evidence and stakeholder review.

Option A — Promote the pilot as it stands
Minimizes preparatory work, but carries unresolved configuration, permission, and ownership assumptions into the release.
Option B — Establish a bounded operating baseline
Reconcile the workload's environment differences, define task-specific access, and agree the response process. Requires platform and data-owner time, but keeps the work limited to this release.
Option C — Redesign the whole platform
Could address broader organizational needs, but expands scope beyond the workload and requires separate funding, authority, and dependency analysis.

Proposed choice: Option B. Record the approved environment differences, access requirements, release checks, and operating responsibilities before deciding the production rollout.

Reconsider if: The existing environment cannot provide the required separation, a mandatory constraint changes, or evidence reveals shared dependencies that cannot be addressed within the workload boundary. Those findings may justify a wider review; they do not automatically authorize it.

04 / Sequenced actions

  1. Reconcile the environment definitions

    Proposed owner: Cloud platform lead with the workload engineer.

    Completion evidence: An approved inventory of intended differences, an explanation for each unmanaged change, and a reviewed plan that avoids unintended replacement or deletion.

  2. Define and verify the access contract

    Proposed owner: Data platform owner and identity/security counterpart.

    Completion evidence: Named task identities, justified permissions, and recorded allowed/denied test cases using synthetic data. No production permission changes are performed by this excerpt.

  3. Assign the operating response

    Proposed owner: Operations lead and reporting owner.

    Completion evidence: A documented definition of timely reporting data, named responders, and an exercised failure/escalation procedure.

  4. Decide the next release

    Proposed owner: Workload sponsor and change owner.

    Completion evidence: A reviewed rollout decision with validation steps, rollback or forward-recovery choices for data changes, and explicit unresolved risks.

This excerpt demonstrates how platform evidence informs a release decision. It does not claim a completed implementation, security certification, cost reduction, or client outcome.

HOW THE REVIEW WORKS

Agree the question.
Make the next step clear.

Work starts with a written scope, fee, inputs, and delivery date. The scope follows your workload and decision; the sample above does not prescribe a universal solution.

Discuss a project or contract
  1. Frame the decision. Identify the workload, environments, stakeholders, and release decision.
  2. Review the evidence. Examine sanitized platform diagrams, infrastructure definitions, access matrices, and operating procedures.
  3. Resolve the important unknowns. Distinguish supported findings from assumptions and agree what needs further verification.
  4. Walk through the recommendation. Review the target design, trade-offs, priorities, and operating responsibilities with the team.
Inputs and exclusions

Useful inputs: A workload description, agreed environment boundaries, existing diagrams, sanitized infrastructure and access definitions, and discussions with platform and data owners.

Not included by default: Implementation, migration, penetration testing, compliance certification, emergency response, or ongoing operations. A broader delivery need can be scoped separately.

Initial reviews use sanitized evidence. System access and implementation are agreed separately. Do not send patient information, credentials, or confidential documents through the inquiry link.
