Every strategy eventually becomes somebody's terminal session.

Cloud architecture, migration, access control and operations — the foundational work that decides whether the target state on the whiteboard ever exists anywhere else.

01Our view

Transformation is not decided in the roadmap. It is decided in the environment.

A target architecture is a diagram until somebody provisions the landing zone, works out how identity federates, decides what an isolated environment actually means for this estate, and runs the migration without dropping a transaction. That work is where programs are won and lost, and it is the work most advisory firms hand to someone else.

The consequences are specific and expensive. Access models designed on a slide fail the first security review. Migrations sequenced without knowing the integration surface run twice. Cloud bills that looked fine in the business case arrive with a run-rate nobody modeled, because the architecture was never costed at the workload level.

We treat infrastructure as a first-class capability rather than the implementation detail at the end of a strategy engagement. The people who set your target state configure the environments, write the Terraform, design the access boundaries and stay on call while it proves itself.

02Service lines

What we actually do in infrastructure.

Named, scoped and independently buyable. Most engagements combine two or three.

01

Cloud architecture & migration

Getting workloads onto the right platform, in the right shape, without a cutover weekend nobody will approve.

  • Rehost, replatform, refactor or retire — decided workload by workload, not by policy
  • Landing zones, network topology and identity foundations built once, properly
  • Parallel-run and reconciliation so cutover is a decision rather than a leap
02

Environment & platform engineering

Reproducible environments that behave the same on a Tuesday as they did during the pilot.

  • Infrastructure as code, with provisioning and teardown that survive staff turnover
  • Environment isolation and tenancy boundaries that hold under audit
  • Golden paths so application teams ship without filing infrastructure tickets
03

Access architecture & security engineering

Designing who can reach what, and proving it — the control that fails first and costs most.

  • Identity federation, privileged access and least-privilege remediation
  • Segmentation and zero-trust boundaries between tenants, tiers and third parties
  • Threat modeling and control evidence mapped to SOC 2, ISO 27001 and HIPAA
04

Reliability & operations

What happens after go-live, which is where most of an estate's life is actually spent.

  • SLOs, error budgets and alerting that pages a human only when it should
  • Observability across logs, metrics and traces, wired before the incident
  • Incident response, runbooks and recovery validation that has actually been rehearsed
05

Cost engineering & FinOps

Making the run-rate a design input rather than a quarterly surprise.

  • Workload-level cost modeling before the architecture is fixed
  • Allocation, showback and commitment strategy across accounts and teams
  • Structural reduction — rightsizing, lifecycle and architecture change, not just discounts
06

Architecture review & technical due diligence

An independent read on whether an estate, a team or an acquisition target is what it claims to be.

  • Current-state assessment across architecture, security, delivery and cost
  • Scalability, key-person and technical-debt risk quantified rather than described
  • Buy-side and sell-side diligence for private equity and corporate development
03Accelerators

We do not start from zero.

Reusable engineering assets we bring into engagements — reference architectures, tested component libraries and assessment methods. They are yours to keep and modify; nothing here is a runtime you have to keep licensing.

Infrastructure blueprint

Landing Zone

Terraform-defined account structure, network, identity and guardrails, deployable on day one.

Reference framework

Access Baseline

Least-privilege role and segmentation patterns with control evidence pre-mapped to SOC 2 and ISO 27001.

Analytical tool

Cost Model

Workload-level total cost of ownership across cloud, license, run and people cost.

Assessment framework

Architecture Radar

Structured evaluation across sixteen dimensions, producing scores comparable over time.

04How we hold ourselves

Four commitments, each with a cost.

01Vendor-neutral by policy
We take no reseller margin and carry no platform quota. Which cloud you belong on is a question about your workloads, not about our commercials.
02The estimate carries the run
A migration priced without its operating cost is not an estimate. Run-rate, on-call load and license drift are modeled with the build.
03Smallest sufficient intervention
We look for the least disruptive change that achieves the objective. Re-platforming everything is a last resort, not a default.
04You hold the keys
Your cloud accounts, your Terraform state, your credentials. We work inside your tenancy, and nothing we build requires us to retain access.
05Where clients start

Infrastructure & Architecture Diagnostic

Three weeks · fixed scope · fixed price

An independent read on your estate: what it costs to run, where it will break, what the access model actually permits, and the three interventions with the highest return — with the reasoning shown rather than asserted.

What you receive

05 outputs

  1. 01Current-state assessment across architecture, security, reliability and cost
  2. 02Access and segmentation review with findings ranked by exposure
  3. 03Workload-level run-rate model and structural savings identified
  4. 04Target architecture with trade-offs made explicit
  5. 05Three highest-return interventions, sequenced and costed
06Technology

What we build on — and why it is a shortlist, not a religion.

We are deliberately fluent across the credible options in each layer so that the choice can be made on your constraints rather than on ours.

Most engagements start with a short, fixed-scope diagnostic — three to four weeks, a written recommendation, and a costed path forward. If we are not the right firm for it, we will say so and point you somewhere better.
