System Design & Architecture

Systems designed to scale, fail safely and be understood by the next engineer.

ClientsAPI gatewayServicesEvent busData storesTypical system shape for this service

Signs you need this

  • Every feature touches every part of the codebase.
  • One slow dependency takes the whole platform down.
  • You are planning for 10x load and nobody can say where it will break.

Overview

Good system design is mostly about boundaries: which service owns which data, how components communicate, what happens when something is slow or down. Get those right and features become cheap; get them wrong and every change is a rewrite.

We produce system designs and architecture decision records for new platforms and for existing ones that have outgrown their original shape, covering service decomposition, event-driven patterns, data ownership and multi-region deployment.

How this differs from Cloud & DevSecOps: System Design decides service boundaries, data ownership and communication patterns; Cloud & DevSecOps builds the infrastructure and pipelines that run them.

What we deliver

  • Architecture blueprintService boundaries, data ownership, communication patterns and deployment topology.
  • Event-driven designKafka-based streaming, CDC and asynchronous workflows where they fit.
  • Scalability planCapacity modelling, caching strategy and horizontal scaling paths.
  • Resilience designFailure modes, retries, circuit breakers, backups and recovery objectives.
  • Architecture decision recordsDocumented trade-offs so decisions survive team changes.
  • Modernisation roadmapIncremental path from monolith to services without a big-bang rewrite.

Where it fits

New platform

Design the foundations for a product before the first line of code.

Scaling pains

Identify the bottlenecks and design the path to 10x load.

Monolith decomposition

Carve out services safely, one domain at a time.

Multi-tenant SaaS

Isolation, tenancy models and per-tenant scaling designed in from the start.

Technology we use

Chosen per project. We are vendor-neutral and will recommend what fits your constraints.

How we work

Context

Business drivers, current architecture, constraints and quality attributes.

Design

Candidate designs with trade-offs, converging on a documented target.

Validation

Prototype the risky parts and review with your engineers.

Roadmap

Sequenced steps with measurable checkpoints.

Typical first engagement

Common questions

Do you write ADRs?

Yes. Every significant decision is recorded with context, options and consequences.

Microservices or monolith?

Whichever fits your team and load. We recommend a well-structured monolith more often than people expect.

Can you review our existing architecture?

Yes. A short assessment produces a prioritised list of risks and improvements.
