Cloudwalker Solutions

Domain ownership.
Federated governance.
One platform.

Stop fighting centralised bottlenecks. Cloudwalker builds AWS-native Data Mesh architectures that let each business domain own, publish, and govern its data products — at scale.

AWS Data Mesh reference architecture

What is Data Mesh

Domain teams own their data. Governance stays enterprise-wide.

A Data Mesh is an architectural approach that decentralises data ownership to the business domains that produce and understand it best — while keeping governance, security, and quality consistent across the whole organisation.

Cloudwalker's AWS-native Data Mesh implementation puts each domain in its own isolated AWS account with its own pipelines, lake, and reporting layer. A shared Federated Governance Account enforces tagging, access control, and cataloguing through AWS Lake Formation — without a central team becoming the bottleneck.

The reference architecture is already running in production for betting operators processing millions of events per day across multiple jurisdictions and domains.

Domain autonomy
Each business domain deploys, operates, and evolves its own data products independently — no tickets to a central data team.
Federated governance
Lake Formation enforces PII tagging, access control, and data quality policies centrally — without central team gatekeeping.
CloudFormation-native IaC
Every domain is a deployable CloudFormation stack — deterministic, auditable, zero drift. Onboarding a new domain takes days, not months.

The problem we solve

Three bottlenecks that break data organisations at scale

Pain 01
Centralised teams can't keep up
Every new report, dashboard, or ML model goes through one bottleneck team. Business domains wait weeks for data they already understand better than anyone. The central team is always behind, always overwhelmed.
Pain 02
Governance is all-or-nothing
Either data is locked down so tightly nobody can use it, or it's a free-for-all with no lineage, no tagging, and no accountability. Both extremes cost the business — one in agility, the other in compliance risk.
Pain 03
On-premise systems holding you back
Legacy databases across business domains — betting platforms, CRM, financial systems — need to feed a modern analytics layer without a risky big-bang lift-and-shift. Domains need to migrate at their own pace.

Our approach

Four pillars of the AWS Data Mesh architecture

01

Federated Governance Account

AWS Lake Formation as the central governance plane. Domain-level and PII tagging via tag-based access control. A governance catalog — the registry of registries — with separation of domain service roles and user roles. No central team gatekeeping: governance is policy, not people.

CI/CD Account

CloudFormation for all infrastructure-as-code — deterministic, auditable, zero drift. CodePipeline and CodeBuild for automated domain deployments. Each domain deploys independently through its own pipeline. Guardrails are enforced at the pipeline level, not by manual review.

03

Domain Accounts

Each business domain gets its own isolated AWS account. Ingestion via DMS CDC, Kinesis Firehose, Lambda, or AppFlow. S3 as the domain data lake. Glue for crawling and ETL. Step Functions for orchestration. Reporting via Redshift, Athena, QuickSight, or Power BI Gateway.

On-Premise Integration

AWS DMS CDC provides low-latency, continuous replication from operational databases without impacting source systems. No big-bang migration — domains migrate at their own pace. Full auditability from source to lake.

05

Real-Time Streaming

Kinesis Firehose and Lambda handle high-velocity event streams — betting ticks, player activity, transaction events — directly into the domain S3 lake. Sub-second latency from operational system to analytics layer.

Reporting Layer

Each domain exposes data through its choice of consumption layer — Amazon Redshift for heavy SQL analytics, Amazon Athena for ad-hoc S3 querying, QuickSight for embedded BI, and EC2-hosted Power BI Gateway for clients who require PBI.

Engagement model

From assessment to production in three phases

1

Data Mesh Assessment

2 weeks — Deliverable: Assessment report + architecture blueprint

Current state analysis of data architecture and organisational structure. Domain identification and ownership mapping. Governance gap analysis against AWS Lake Formation capabilities. Recommended target architecture and migration roadmap tailored to your technology stack and team structure.

Domain mapping Governance gap analysis Architecture blueprint
2

Foundation Build

4–6 weeks — Deliverable: First domain live in production

Federated Governance Account setup — Lake Formation, PII tagging taxonomy, and central catalog. CI/CD Account with CloudFormation stacks, CodePipeline, and CodeBuild pipelines. First Domain Account deployed as a reference implementation with full ingestion, processing, and reporting layers. Operational runbook and team enablement sessions.

Domain Expansion

2–3 weeks per domain — Repeatable, autonomous onboarding

Repeatable domain onboarding using CloudFormation templates from Phase 2. Source integration configured per domain — DMS CDC for transactional databases, Firehose for streaming, AppFlow for SaaS sources. Domain-specific Glue processing pipelines and Step Functions orchestration. Reporting layer activated. Each domain is independent from day one.
