Cloud: architecture, migration and cost

Design and build of environments in Azure, AWS or Google Cloud, migration of existing systems and a clear view of where your cloud money goes.

What we do

  • Design an architecture that matches your size. No enterprise constructs for three applications, but no makeshift setup you’ll tear down in a year either.
  • Build the cloud foundation (landing zone) as code: networks, identity, policies, logging, backups and separate environments.
  • Move existing systems to the cloud in waves, with a pilot and a parallel run.
  • Go through your costs and set up budgets, alerts and rules so the cloud bill doesn’t grow silently.

What you get

  • An environment you understand. Documentation, diagrams and runbooks, not just portal access.
  • Everything as code in your repository. You can take it over, extend it or hand it to anyone else.
  • Security from the start. Separate accounts, least privilege, encryption and an audit trail as the default.
  • A clear cost of operation. You know what the cloud will cost per month before you move in.

How we work

We start with a short call and read-only access. Within two weeks you know what state your environment is in and what makes sense to tackle first. Then we agree on a concrete scope and price. We work in Azure, AWS and Google Cloud, whichever makes sense for you, not for us.

Typical engagements

Scope and price are agreed upfront. Most engagements fit into days and weeks, not months.

Cloud architecture review

Scope: 1–2 weeks

An independent look at your environment. Security, network, identity, cost, operations and resilience. You get a map of the current state, a target architecture and a step-by-step plan with effort estimates.

Landing zone

Scope: 4–8 weeks

The foundation of your cloud as code. Network, identity, policies, monitoring and separate environments for dev, test and production. A new environment is one pull request away.

Cloud migration

Scope: depends on size

Applications and servers moved in waves. Pilot, parallel run and cutover in an agreed window, with no downtime for users.

Cost control (FinOps)

Scope: 2–3 weeks

Costs broken down by service and team, right-sized resources, reservations, budgets and alerts. Savings quantified in money per month, not in percentages on a slide.
