Platform path

Kubernetes platform: ship without losing control.

Your teams need to ship on their own without losing control of access, resources and traces. As a Kubernetes consultancy, we start by placing the platform in its lifecycle. We then build a repeatable path to production, backed by shared tools and rules: this is platform engineering.

First step: choose between foundations, go-live, migration and optimisation. Each path ends with a deliverable and a decision on what comes next.

Describe your platform

Choose your starting point.

The path shows the first action, the expected deliverable and the decision that opens the next stage. Detailed pages for stages 02 to 04 are currently available in French.

  1. Foundations

    Govern who deploys, where and within which limits.

  2. Go-live

    Check the service, test the rollback, then open in stages.

  3. Migration

    Test a pilot before migrating in waves.

  4. Optimisation

    Measure a problem, apply a change, verify its effect.

Give autonomy without losing control.

We start by governing access, resources, secrets and traces, then we make this delivery path repeatable.

Governed self-service

This path relies on four controls: identities, quotas, secrets and audit log.

Step by step

  1. The team signs in with single sign-on (SSO). Role-based access control (RBAC) limits what it can deploy.
  2. We create its environments within explicit limits: resource quotas, namespaces and authorised networks.
  3. We distribute secrets from a managed vault, with documented permissions and rotation.
  4. We keep a record of administration and deployment actions: identity, operation, date and permission used.

We apply this framework to every team that uses the platform. The tools, for example Keycloak, Okta, Argo CD or Terraform, are chosen after the governance rules they must enforce.

Tie every alert to an action.

An observability sprint, a short engagement that makes the state of the service visible, links signals, alerts and procedures to the decisions to be made in production.

Useful signal threshold action procedure

We define the useful signals, thresholds tied to an action, first-level procedures (runbooks) and a shared dashboard. The deliverable serves during a build, a migration or the preparation for operations.

Before a cloud managed services engagement, we check that the technical signals (telemetry) make it possible to detect, qualify and track deviations. The sprint establishes this baseline when it is missing.

Deliverables, prerequisites and limits.

Deliverables

  • Versioned platform configuration
  • Repeatable delivery chain
  • Access rules, quotas, secrets and traces
  • Operations documentation handed over

What to gather

  • A named production objective
  • Temporary, traceable access
  • The owners of the components concerned
  • An agreed intervention window

Separate scopes

  • Business features are owned by the product team.
  • Ongoing operations fall under a separate engagement.

One-off diagnosis falls under our audits; this pillar builds and transforms. If the starting state is not established, an audit comes first.

Platform to scope

Describe your platform and the next deadline.

Tell us the lifecycle stage, the existing setup and the deadline. We point you to the first useful piece of work and the deliverable to scope.

Describe what you need to achieve, the system concerned and what prevents progress today.
