Platform Engineering

Platform engineering is the discipline of building a shared internal platform: the cloud accounts, container orchestration, deployment pipelines, monitoring and access rules a development team needs to ship code. A platform team owns that layer on behalf of every other team in the organization. The platform it produces is an internal developer platform, and the standardized, pre-approved route through it is a golden path.

A bank adopts platform engineering for the same reason a tech company does: individual product teams stop rebuilding the same pipeline, the same logging setup and the same access review each time they start a new service. The difference for a bank sits in the audit trail. A golden path in a regulated environment has to produce the same evidence a manual review would have, every time a developer uses it.

DevOps is the set of practices that makes a development team responsible for its own code from the first commit to the running service in production. Platform engineering does not remove that responsibility; it adds a dedicated team that builds the shared tools so every other team's DevOps work gets easier. A bank running both assigns DevOps practices to product teams and shared infrastructure to the platform team, so product teams can reuse that infrastructure.

German banks and fintechs run both practices in Frankfurt, Berlin and Munich, the three event cities of Finance Loop. A platform team answers the same daily questions a DevOps engineer asks, who approved this change, where does this secret live, what happens when a pipeline step fails, once for the whole organization instead of once per team.

Platform engineering is the practice of building and running a shared internal platform so application teams can provision infrastructure and deploy software on a self-service basis. A platform team builds the platform; application teams use it. The term names the team and the practice, not a single product a bank buys off the shelf.

DevOps names a set of habits a development team adopts for its own code. Platform engineering names a team whose job is to build the shared infrastructure that makes those habits practical across every team at once. A bank can run DevOps without a platform team, with each team building its own pipeline; platform engineering exists to make that unnecessary.

An internal developer platform is the set of tools, services and self-service interfaces a platform team builds on top of an organization's infrastructure. A developer portal, such as the open-source project Backstage, is often the interface on top of it. The internal developer platform page covers the category on its own.
