We architect on AWS — Cognito, Lambda, S3, CloudFront, CloudWatch — with infrastructure as code and observability built in.
AWS is our standard cloud. We deliberately go deep in one platform rather than shallow across three — it produces more reliable, better-priced infrastructure because the team knows the failure modes.
One cloud, known deeply
We run AWS and we say so plainly rather than claiming equal mastery of three hyperscalers. Cloud platforms differ in the details that actually cause incidents: IAM behaviour, service quotas, regional availability, pricing cliffs, failure modes under load. Knowing those for one platform produces more reliable and cheaper systems than surface familiarity with several.
In practice that means Cognito for identity, Lambda for serverless logic, S3 with encryption for storage, CloudFront for global delivery, RDS or DynamoDB depending on the data shape, and CloudWatch for metrics, logs and alerting.
How we keep cloud costs honest
Unexplained cloud bills are usually architectural, not accidental. Compute sized for peak and left running. Data egress never modelled. Storage tiers never reviewed. Environments spun up for a test and forgotten. We model expected cost against realistic load before committing to a pattern, tag resources so spend is attributable, and review it deliberately rather than when finance escalates.
Infrastructure is defined as code, which makes environments reproducible, changes reviewable, and mistakes revertible. It also means a new engineer can understand your platform from the repository instead of by clicking through a console.
Security, residency and operations
Least-privilege roles from the first deployment rather than permissive ones tightened later — a promise that is rarely kept. Secrets managed properly and never committed. Encryption in transit and at rest. Access logging that supports audit rather than just debugging. Where Australian data-residency obligations apply, we architect for regional hosting from the outset.
Delivery for clients such as Murray Engineering and Harcourts Property Specialists uses this foundation for global content delivery and video performance; for Know Your Asset it supported the architecture documentation that enterprise procurement and investors reviewed.
Why AWS specifically?
Depth of managed services, mature compliance tooling and the breadth of the local talent pool. For payments and regulated work in particular, the audit and encryption primitives are well-established and well-documented, which shortens every compliance conversation.
Are we locked in?
Partly, and we are direct about it. Managed services trade portability for reliability and speed. We keep application logic portable and are explicit about which components are deliberately AWS-specific, so the trade is a decision rather than a surprise.
How do you keep cost under control?
Right-sizing, autoscaling, lifecycle policies on storage and tagging so spend is attributable to a service. Reviewed on a cadence — cloud cost creeps upward by default unless somebody is looking at it.
