Enterprise Architecture

Systems that scale, survive, and pay back

We design the spine of your platform โ€” clear domains, sound integrations, and infrastructure that won't be the bottleneck five years from now.

Pillars

Six things every enterprise architecture needs

We bring depth in each โ€” and tailor the mix to your stage and constraints.

Domain modelling

Bounded contexts, clear ownership, and APIs that match the business.

  • Event storming
  • Strategic DDD
  • Service decomposition

Integration design

Choose synchronous, async, or batch โ€” and never regret it later.

  • Event-driven patterns
  • API contracts
  • Saga & outbox

Cloud foundations

Landing zones, networking, and cost guardrails done right the first time.

  • Multi-account AWS / GCP
  • Network topology
  • FinOps controls

Resilience & security

Design for failure: redundancy, blast radius, and zero-trust.

  • HA & DR planning
  • Zero-trust mesh
  • Threat modelling

Performance

Find the bottleneck before production does.

  • Capacity planning
  • Caching strategy
  • Load shaping

Governance

Decisions captured, standards enforced, autonomy preserved.

  • ADRs & RFCs
  • Platform standards
  • Tech radar
Migrations

From legacy to leverage

Most enterprises don't need a rewrite โ€” they need a smart sequence of strangler-fig moves. We chart the path and de-risk each step.

01

Assess

Inventory, dependencies, and risk hot spots โ€” mapped in week one.

02

Stage

Pick the seams. Sequence work to deliver value monthly.

03

Strangle

Wrap legacy with adapters. Move traffic incrementally.

04

Retire

Decommission with confidence โ€” and document what you learned.

Architecture you can argue with

Every choice is documented in an ADR you can challenge. We're allergic to hand-wavy diagrams.

EYESA's architecture review surfaced three risks our team had been side-stepping for a year. Two months later we were running multi-region, with a clear capacity plan.

Need a fresh pair of architect's eyes?

We run two-week architecture reviews โ€” fixed scope, fixed price. Walk away with a written report and a sequenced roadmap.
