How to choose a platform engineering partner
Platform engineering has matured from a Kubernetes-adjacent practice into a defined operating model where a central platform team builds and operates an internal developer platform (IDP) as a product for internal application teams. The dominant 2026 platform engineering programme combines a developer portal (Backstage, Port, Cortex), an opinionated golden path catalogue (paved roads for service creation, deployment, observability, and security), GitOps deployment, and policy as code controls. Partner selection should prioritise product-management discipline as heavily as Kubernetes engineering depth.
Three procurement archetypes recur. Platform engineering specialists (Thoughtworks, Container Solutions, Contino, Liatrio, Slalom Build) lead on IDP build programmes where engineering depth across the CNCF ecosystem and product-management discipline combine. Enterprise modernisation firms (EPAM, SoftServe, Cprime, Kainos) lead on at-scale platform programmes that integrate IDP build with broader modernisation and operating-model change. Platform vendor services (Humanitec, Spotify Backstage, Roadie, Red Hat Consulting, Codefresh Services) lead on platform-specific adoption where their tool is the chosen IDP foundation.
For complementary research see internal developer platforms, DevOps platforms, observability platforms, and policy as code. For adjacent services see DevOps and SRE services, Kubernetes services, Terraform and IaC consulting, and application modernisation.
Frequently Asked Questions
What does a platform engineering programme cost?
A foundation IDP build (developer portal, golden path catalogue for service creation, deployment and observability, GitOps baseline, policy as code MVP) for an organisation with 10-50 application teams typically runs $1.2-3.5M across 6-12 months. Scaled platforms with paved roads across the full SDLC, multi-environment promotion, FinOps integration, and rich developer experience commonly run $4-15M across 12-24 months. Ongoing platform team support typically runs $80-400k per month depending on team size.
Build versus buy on the developer portal?
Buy a managed Backstage (Roadie, Spotify Portal) or a commercial IDP (Port, Cortex, Humanitec) by default. Self-hosted Backstage is appropriate only where the organisation has a sustained platform engineering investment, an opinionated plugin strategy, and at least three full-time engineers committed to portal maintenance. Most stalled IDP programmes are self-hosted Backstage deployments that became single-engineer projects.
How do we measure platform success?
Measure four dimensions from day one: developer experience (DevEx surveys, time-to-first-deploy for new joiners), throughput (DORA metrics: deployment frequency, lead time, change failure rate, MTTR), efficiency (platform team unit cost per application team served), and business outcome (platform-enabled feature shipping volume). Programmes that measure only platform team output without developer-experience instrumentation consistently underperform.
What is the right team size?
A central platform team typically sizes at 4-8 engineers for the first 10-30 application teams it serves, with one platform engineer per 8-12 application teams at steady state. Below that ratio, the team becomes a delivery bottleneck; above it, the platform drifts from application-team needs. Treat the team as a product organisation with a product manager, designer, and platform engineers, not a DevOps team renamed.
What contract structure works for platform engineering work?
Fixed-price for clearly scoped IDP foundation phases (portal MVP, golden path catalogue, GitOps baseline, policy as code MVP). Time-and-materials with capped sprints for application-team onboarding and custom golden path development. Outcome-based fees aligned to developer experience metrics (lead time, DORA improvements, paved-road adoption rates) for mature programmes. Always require all platform IaC, plugins, and templates in customer-owned repositories from day one.
