Cloud Architecture & Landing Zones
Accounts, networks, and guardrails designed before the first workload.
Most cloud sprawl is a missing foundation: workloads landed in one account with one flat VPC, and three years later nobody can say what talks to what or why the bill doubled. We build landing zones first — account and project structure, identity and permission boundaries, network segmentation, logging, and guardrails — on AWS and GCP, matched to the organisation rather than copied from a reference PDF. VPC design and CIDR planning get carrier-grade attention because re-addressing a production cloud later is the most expensive network change you will ever make.
- Account/organisation architecture: OUs, projects, guardrails (SCPs, org policies), and break-glass design
- VPC design and CIDR planning — subnets, route tables, and segmentation that survive growth and peering
- Identity foundations: IAM roles and least privilege, federation with Entra ID, and permission boundaries
- GCP comparative strengths applied deliberately: global VPCs, native any-to-any routing, and global load balancing
- Compute strategy: instance families, autoscaling, spot/on-demand/reserved economics, stateless vs stateful placement
- Storage architecture: S3/EBS/EFS and GCS/PD trade-offs on durability, performance, and cost
- Logging, audit, and encryption baselines wired in from day one — CloudTrail, KMS, and config rules
- Architecture reviews of existing estates: what to keep, what to fix, what to stop paying for
A cloud foundation that scales by addition, not by archaeology.
