AWS cloud migration

Move workloads to AWS with a landing zone, a migration plan and a cost model agreed before anything moves.

  • Fixed-scope migration programme
  • From USD 35,000
  • Updated

The short answer

AWS cloud migration moves applications and data from on-premise or another cloud into AWS. LDelight starts with a landing zone covering accounts, networking, identity and guardrails, then migrates workloads in waves — most clients see a 25–40% reduction in run costs against their pre-migration baseline.

Key takeaways

  • Landing zone with account structure, guardrails and cost controls before wave one
  • Workloads assessed individually: rehost, replatform, refactor or retire
  • Migration in waves with rollback available at every step
  • A costed model agreed up front, not discovered on the first invoice
AWS cloud migration

Most disappointing AWS migrations are lift-and-shift projects where nothing was re-examined on the way. The workload arrives running the same oversized instances it had in the data centre, the bill goes up rather than down, and the promised agility never materialises because the operating model did not change.

Landing zone first

Before a single workload moves we build the foundation: a multi-account structure under AWS Organizations, network topology and connectivity, identity federation to your existing directory, logging and guardrails through Control Tower and service control policies, and tagging enforced from day one so cost attribution actually works later.

Assess every workload on its merits

Each application gets a recommendation — rehost, replatform, refactor, repurchase, retire or retain — with the cost and effort attached. Some workloads genuinely should not move. Saying so is part of the job.

Migrate in waves

Low-risk workloads go first to prove the runbooks. Each wave ends with a validation gate and a documented rollback. Nothing moves on a Friday.

Then optimise

Post-migration we right-size against real utilisation data, apply Savings Plans and Reserved Instances against the steady-state baseline, and set up budgets and anomaly detection. This is where the reduction against the pre-migration baseline actually comes from.

How we deliver

  1. 1

    Discovery and assessment

    Automated discovery of the estate, dependency mapping and a per-workload migration recommendation with cost and effort attached.

  2. 2

    Landing zone build

    Multi-account structure, networking, identity federation, logging, guardrails and tagging policy — all as Terraform you keep.

  3. 3

    Pilot wave

    A low-risk workload migrated end to end to prove the runbooks, the cutover process and the rollback.

  4. 4

    Migration waves

    Remaining workloads in dependency-ordered waves, each with a validation gate before the next begins.

  5. 5

    Optimise and hand over

    Right-sizing against 30 days of real utilisation, commitment purchases, budget alarms, runbooks and team enablement.

What you get out of it

  • 25–40% typical reduction against the pre-migration run rate
  • Recovery objectives met with tested, automated procedures
  • Cost attributable to team and product through enforced tagging
  • A platform your engineers can actually self-serve on

FAQs about AWS cloud migration

The landing zone takes 3–5 weeks. Migration itself depends on the estate: a 20-workload environment is typically 3–4 months in waves; several hundred workloads is a 9–18 month programme. We give a wave plan with dates at the end of assessment.

Only if you do the optimisation work. A pure lift-and-shift usually costs more than the data centre it left. The reduction comes from right-sizing against real utilisation, retiring what nobody uses, and buying commitments against a stable baseline — which is why we treat those as part of the migration rather than a later project.

For most stateless applications, yes, using replication and DNS-based cutover. Stateful databases usually need a short, planned window — typically under 30 minutes with AWS DMS and continuous replication. We tell you which of your workloads fall into which category during assessment.

They get replaced with something that is actually tested. We design recovery objectives with you, implement them with automation, and run a real failover exercise before sign-off. An untested DR plan is a document, not a capability.
