Singlet 1ES – One Engineering System for Azure

Singlet 1ES – One Engineering System for Azure

Singlet 1ES is a Microsoft-aligned engineering system on Azure that standardises and secures the full software lifecycle—from backlog to production—through governed pipelines, landing zones, FinOps controls, portfolio governance, and managed AI-enabled engineering.

Solution Overview

Singlet 1ES is a productised implementation of Microsoft’s One Engineering System (1ES) model on Azure. It standardises how software is planned, built, secured, and operated by embedding security, compliance, governance, and cost control directly into the engineering system. Teams retain flexibility in languages and architecture, while delivery, lifecycle, and operations are standardised. The solution is delivered as a mandatory Foundation with modular Workstreams, enabling incremental adoption while operating as a single, consistent platform. It is designed for enterprise-scale environments, particularly in regulated and security-sensitive industries.

Business Challenges Addressed

Organisations typically face:

Inconsistent DevOps and cloud practices Security and compliance applied late or manually Fragmented and inconsistent SDLC processes Repeated implementation of pipelines and controls Cloud cost overruns addressed after deployment Limited visibility across engineering and operations Uncontrolled AI tooling outside governed pipelines

Singlet 1ES addresses these by establishing a centrally governed engineering system on Azure.

Solution Value

Standardised SDLC across all teams Security and compliance by design Accelerated delivery through reusable patterns Audit-ready operations with full traceability Predictable cloud spend with embedded FinOps Governed AI adoption within controlled pipelines

Architecture Overview

Singlet 1ES is deployed into the customer’s Azure tenant as:

Foundation (mandatory)

CAF-aligned Azure landing zone Infrastructure as Code (Terraform/Bicep) Security, DevSecOps, and FinOps assessments

Workstreams

Security & Compliance (Azure Policy, Defender, SIEM) Cost Governance (budgets, anomaly detection) Engineering Standardisation (pipelines, GitHub, security scanning) Observability (centralised monitoring and telemetry) Portfolio Delivery (Azure Boards governance) Agentic Engineering (governed Copilot and AI workflows)

Deployment Model

Implemented in customer-owned Azure subscriptions Azure-native and aligned with CAF best practices Delivered incrementally with progressive onboarding Includes documentation, enablement, and knowledge transfer

Singlet acts as the implementation partner, transferring knowledge and enabling internal teams.

Positioning

Singlet 1ES is not a single DevOps tool or advisory-only framework. It is a complete operating model implemented through Azure architecture, pipelines, policies, and controls.

Target Customers

Medium and large enterprises, including financial services, public sector, telecoms, energy, and organisations standardising Azure and DevSecOps across multiple teams.
