AWS Cloud Architecture

Architecture you can defend, and a bill you can predict.

Certified on AWS and opinionated about it, while staying vendor-neutral above the platform layer. Most cloud cost problems are architecture problems, which is why the review and the savings work are the same project.

What we do

  • Well-Architected reviewStructured review across operational excellence, security, reliability, performance, cost and sustainability, with a prioritised remediation plan.
  • AWS Data LakeS3-based lakes built with a real zone structure, raw through curated, governed by Lake Formation permissions and a Glue Catalog that keeps schema and ownership honest as sources multiply.
  • AWS Data WarehouseRedshift architecture sized to the workload: RA3 nodes, distribution and sort keys chosen for how the warehouse is actually queried, workload management, and Spectrum where the lake and the warehouse need to act as one.
  • ETL/ELT modernisationMoving pipelines off brittle hand-rolled scripts or ageing on-premise ETL tools onto Glue, Step Functions and managed Airflow (MWAA), with the same logic made observable, testable and owned by someone other than whoever wrote it.
  • Managed data engineeringOngoing ownership of the pipelines once they are live: on-call for failures, a monthly platform and cost review, and planned change instead of whoever is free picking up the incident.
  • Landing zone & multi-account designAccount structure, organisational units, guardrails, network topology and centralised logging built for growth.
  • Cloud migrationOn-premise to AWS planning and execution, including hybrid cutover with shadow validation for low-downtime moves.
  • FinOps & cost optimisationLine-by-line spend audit, quick wins implemented during the project, and structural recommendations with quantified savings.
  • Infrastructure as codeTerraform and CloudFormation provisioning, environment parity, CI/CD for data infrastructure and automated testing.
  • Resilience & disaster recoveryRecovery objectives agreed with the business, failover design and tested restore procedures.

Who usually owns the budget

CTO, Head of Platform, or a Finance lead who has seen the cloud bill trend line.

What triggers the purchase

  • The monthly bill grows faster than usage does
  • A migration has stalled halfway and both estates now need running
  • Nobody can say what happens if the primary region goes down
  • The data lake has quietly become a data swamp nobody trusts
