Cloud Migration & Modernisation

Move workloads to AWS, Azure, Google Cloud or hybrid and refactor the legacy systems that hold you back.

Cloud migration done well lowers cost, improves resilience and removes the hardware you were dreading replacing. Done badly it moves the same problems to a more expensive place. The difference is a readiness assessment, a target architecture and a runbook that is rehearsed before the real cutover.

Modernisation goes further: containerising applications, replacing brittle components and retiring what nobody uses, so the cloud estate is smaller and simpler than what it replaced.

How we're different
  • We give you the cost model before you commit, including the option of not migrating something.
  • Cutovers are rehearsed in a staging environment so the real one is boring.
  • Security and compliance controls are built into the landing zone from day one.
Who this is for
  • An airline or bank with a data centre lease ending and workloads nobody has inventoried.
  • A manufacturer running production systems on hardware past its support date.
  • A group consolidating several acquired estates into one cloud landing zone.
Signals you need this now
  • Hardware refresh proposals have arrived and the decision has been deferred twice.
  • Nobody can list every application, its owner and what it depends on.
  • An earlier migration moved the cost problem rather than solving it.
  • Regulators or auditors have asked where data is held and how it is recovered.
Scope of work

What is included.

  1. 01

    Readiness assessment

    Application inventory, dependencies, data volumes, compliance constraints and a cost model per option.

  2. 02

    Target architecture

    Landing zone, networking, identity, security controls and the pattern for each workload.

  3. 03

    Migration runbook

    Wave plan, cutover steps, rollback points and test criteria per workload.

  4. 04

    Execution

    Migration waves delivered with monitoring and stakeholder communication.

  5. 05

    Modernisation

    Refactoring, containerisation and managed service adoption where it pays.

  6. 06

    Cost optimisation

    Rightsizing, reservations and tagging so the bill stays predictable.

Method

Four steps, no surprises.

  1. 01

    Assess

    Inventory, dependency mapping and cost modelling across options.

  2. 02

    Design

    Target architecture and landing zone with security sign-off.

  3. 03

    Migrate

    Waves executed to the runbook with rollback available at each step.

  4. 04

    Optimise

    Post-migration tuning of cost, performance and operations.

How the engagement runs

From first meeting to steady state.

  1. 01Weeks 1 to 5

    Readiness assessment

    Application inventory, dependency mapping, compliance constraints and a cost model per option.

  2. 02Weeks 6 to 9

    Target architecture

    Landing zone, networking, identity and security controls designed and signed off.

  3. 03Months 3 to 8

    Migration waves

    Workloads moved wave by wave to a rehearsed runbook with rollback at every step.

  4. 04Month 9 onwards

    Optimise

    Rightsizing, reservations, tagging and operational tuning.

What we measure
  • Run cost of the migrated estate against the pre-migration baseline.
  • Recovery time and recovery point achieved in rehearsal against target.
  • Share of workloads migrated within their planned wave.
  • Unplanned downtime during cutover against the agreed window.
Who is on the engagement
  • Cloud architect
  • Migration lead
  • Platform engineers
  • Security engineer
  • Programme manager
Deliverables
  • Readiness assessment and cost model.
  • Target architecture and landing zone.
  • Migration runbook with wave plan.
  • Migrated workloads with monitoring.
  • Cost optimisation report.
Engagement terms

Assessments are fixed scope and take three to five weeks. Migrations are scoped as fixed-scope waves once the assessment is complete, and typically run from two to six months depending on estate size. Ongoing cloud operations can move to a managed retainer afterwards.

FAQ

Cloud Migration & Modernisation, in plain terms.

The one that fits your workloads, skills and existing licences. We work across AWS, Azure and Google Cloud and often recommend keeping some things on-premises.

Most cutovers can be done with minutes of downtime or none. Where an outage is unavoidable it is scheduled, communicated and rehearsed.

Usually. Some are lifted as they are, some are containerised and some are replaced. The assessment tells you which applies to each.

Tagging, budgets, alerts and a monthly review. We build cost visibility into the landing zone so nobody is surprised.
