Services01

Cloud foundations that stay coherent as you grow.

Most cloud estates are not designed. They accumulate. We replace accidental architecture with a deliberate one: accounts, networks, identity and environments structured so that the next hundred services fit as cleanly as the first ten.

Challenges

The problems we usually find.

  1. Accounts and subscriptions without a structure

    Production, staging and experiments share boundaries they should not. Blast radius is unclear, billing is hard to attribute and nobody is sure which resources are still in use.

  2. Networks that were never designed

    Overlapping address ranges, ad-hoc peering and public endpoints added under deadline pressure. Every new connection becomes a project, and hybrid links are fragile.

  3. Migrations that move problems instead of solving them

    Lift-and-shift without a target architecture carries yesterday’s constraints into a more expensive platform. The opportunity to simplify is lost.

  4. Cost that grows faster than usage

    Oversized instances, idle environments, unmanaged storage and data transfer that nobody modelled. Spend is visible on the invoice but not in the architecture.

Capabilities

What we build and change.

  • Landing zones and account strategy

    Multi-account and multi-subscription structures with guardrails, central identity, logging and network hubs, provisioned as code from day one.

  • Cloud networking

    Address planning, hub-and-spoke or transit topologies, private connectivity, DNS strategy, and controlled ingress and egress.

  • Hybrid infrastructure

    Redundant private links to on-premises and VMware estates, consistent routing and name resolution on both sides, and a clear plan for what moves and what stays.

  • Migration and modernization

    Assessment, target architecture and wave planning. Rehost where it makes sense, re-platform onto managed services or containers where it pays off.

  • Identity and security foundations

    Federated access, least-privilege roles, workload identity instead of static keys, and audit trails that are on by default.

  • Resilience and recovery

    Multi-zone and multi-region patterns chosen against explicit recovery objectives, with restore paths that are tested rather than assumed.

  • Cost architecture

    Allocation models, right-sizing, commitment strategy and architectural changes that reduce spend structurally rather than through one-off clean-ups.

Engagements

Where engagements usually start.

  • A

    Establishing a cloud foundation

    An organization moving beyond a single account needs a landing zone, identity model and network design that teams can build on independently.

  • B

    Data centre or hosting exit

    Workloads need to move to the cloud on a timeline, with a target architecture that avoids recreating the old constraints.

  • C

    Consolidating a fragmented estate

    Several teams built in parallel. Accounts, networks and conventions diverged and now need to converge without stopping delivery.

  • D

    Architecture review before scale

    A platform that works today is about to take on much more traffic, data or teams, and needs an independent view of where it will strain first.

Technologies

Tools we use here.

  • AWSMulti-account organizations, networking, EKS, serverless and data services.
  • Microsoft AzureLanding zones, hub-and-spoke networking, AKS and hybrid connectivity.
  • Google CloudResource hierarchy, shared VPC, GKE and managed data platforms.
  • TerraformModule design, state architecture and automated plan and apply.
  • OpenTofuOpen-source Terraform-compatible provisioning and migrations to it.
  • VMwareOn-premises estates, hybrid connectivity and migration planning.
  • KubernetesCluster design, multi-tenancy, autoscaling and policy.
  • IAMLeast-privilege access models, federation and workload identity.

Approach

How we work on it.

  1. 01

    Map what exists

    Inventory accounts, networks, identities and data flows. Most decisions depend on constraints that are only visible once the current state is mapped.

  2. 02

    Define the target

    A written target architecture with explicit trade-offs, recovery objectives and cost expectations, reviewed with the engineers who will run it.

  3. 03

    Build the foundation as code

    Every account, network and policy is declared in version-controlled infrastructure code, so the foundation can be reviewed, reproduced and extended.

  4. 04

    Move in waves

    Migrate and modernize incrementally with clear rollback points, starting with workloads that validate the architecture rather than the most critical ones.
