A foundation built to scale

A SaaS B2B business working with Cloud Combinator on AWS. The client is anonymised at their request.

The challenge had three focus areas that shaped the engagement.

We structured the engagement so that every decision in the migration was backed by evidence gathered in the assessment, and so the client could approve the plan and the projected costs before any workloads moved.

The engagement met its acceptance criteria. The client's essential services now run on AWS as they did on DigitalOcean, provisioned to best practice and validated with the team, with a costed plan that let the business commit to the move with confidence.

• Evidence-led decision — The assessment delivered a fully costed AWS estimate and a service-by-service comparison, so the full migration was an informed choice rather than a gamble.
• Like-for-like continuity — Compute, databases, and storage were lifted and shifted to EC2, RDS, and S3, keeping the marketplace behaving as it did before while opening the door to later improvement.
• Built to best practice — Least-privilege IAM, private-subnet isolation, encryption, budget alerts, and infrastructure as code were baked in from the start.
• Consolidated and owned — The client received full documentation, a read replica for reporting, and a knowledge-transfer session, leaving the team able to run the platform themselves.
• Handover — Included migration runbooks, the CloudFormation templates, and operational guidance for the migrated environment.

With a best-practice AWS foundation in place, the client is positioned to scale its marketplace and to build on the platform, no longer constrained by its earlier hosting but set up to support whatever the business takes on next. That foundation directly enabled the later migration of the client's AI services onto AWS.
