AWS Cloud Architecture & Migration

Design and migration for AWS estates. Networking, cost control, and an architecture you can grow into.

Technologies & tools
Multi-VPC estate joined through a transit gatewaySeveral VPCs — shared services, workloads and data — connect to a central transit gateway rather than peering with each other directly, so adding a VPC is one attachment rather than a new link to every existing one. An on-premises network reaches the same gateway, which is the path a migration runs over. Networking is sized to avoid throttling under sustained load, and instances are right-sized against observed usage rather than at the size they were first provisioned.Shared services VPCWorkload VPCData VPCTransitGatewayOne attachmentper networkOn-premisesExisting estateRight-sizingMeasured usage,not the size itwas provisioned atNetworking sized for sustained load, so throttling does not appear later.The migration runs over the same path.
A transit gateway in the middle rather than a peering mesh, so adding a VPC is one attachment instead of a link to every existing one.

Most AWS estates are not designed so much as accumulated. An account here, a VPC there, a networking decision made under deadline three years ago that everything now depends on. It works, until the bill or the blast radius makes it somebody's problem.

We design AWS architecture that is deliberate, and we migrate onto it without a big-bang cutover.

Where we usually start

  • Networking. Multi-VPC architectures with transit gateways, designed so isolation is structural and not a matter of remembering to configure it.
  • Cost. Right-sizing, reserved capacity, and finding the resources nobody has owned since the person who created them left.
  • Performance. Including the failure modes that never show up in a diagram, such as network throttling that only appears under sustained real load.
  • Migration. Moving off on-premises or another provider incrementally, with a working rollback at each stage.

Who this suits

Media organisations running high-definition streaming infrastructure, financial institutions needing secure and compliant environments, public sector bodies building analytics platforms at scale, and any organisation whose cloud spend has started growing faster than its usage.

What you end up with

An estate whose shape you can explain, a bill you can predict, and infrastructure defined in code so the next change does not require archaeology.
