Platform Architecture

A reference architecture for building internal platforms that scale with your organisation, not against it.

The Platform Architecture blueprint codifies the structural decisions that underpin successful internal developer platforms in regulated enterprises. It defines the layering of capabilities, from infrastructure provisioning through shared runtime services to domain-specific product layers, and establishes the contracts, ownership boundaries and governance model needed to operate them at scale.

Key Features

Capability Layering Model

A proven decomposition of platform concerns into infrastructure, runtime, shared services and domain layers, each with clear ownership and interface contracts.

Golden Path Templates

Opinionated service and infrastructure templates that encode organisational standards for security, observability and compliance, reducing onboarding time from weeks to hours.

Platform Team Topology

Team structure and interaction patterns derived from Team Topologies principles, defining how platform teams, stream-aligned teams and enabling teams collaborate.

Governance and Guardrails Framework

Policy-as-code guardrails and architectural fitness functions that enforce non-functional requirements without blocking developer velocity.

Use Cases

Internal Developer Platform for Digital Banking

Banking

Establishing a shared platform foundation for a challenger bank launching multiple lending and current account products on independent delivery cadences.

Post-Merger Technology Consolidation

Financial Services

Defining a target platform architecture to consolidate overlapping technology estates following an acquisition, enabling gradual migration without service disruption.

Regulatory-Compliant Multi-Cloud Foundation

Insurance

Architecting a platform layer that abstracts cloud provider specifics while satisfying data residency, encryption and audit requirements mandated by financial regulators.
