Who it is for

For developers and administrators who decide for a team how code reaches production: team leads, platform and operations roles, anyone who wants to go beyond a first pipeline of their own.

Prerequisites

K3 (modules 3.1, 3.2 and 3.7) or equivalent experience with Git, a .NET application and a first pipeline; Azure basics from AZ-900 compact, AZ-104 helps. The exercises need a GitHub account, an Azure DevOps organization of your own and an Azure account; lesson 0.1 explains cost and clean-up.

Afterward, you can

  • Set up work flow, traceability and metrics with GitHub Projects, Azure Boards and dashboards
  • Design branching strategies, pull request rules, large repositories and the recovery of data
  • Choose and justify packages, feeds and versioning
  • Design and run pipelines with YAML, templates, runners and agents, a test strategy, approvals and checks
  • Choose deployment strategies: blue-green, canary, rings, feature flags, hotfix, database changes
  • Place infrastructure as code, desired state and pipeline maintenance
  • Design identities, permissions, secrets and security checks in automation
  • Observe the delivery chain with Azure Monitor, alerts and metrics

Final project: the Kladde

What the Kladde can do after this course

No further work on the Kladde but a final project: the DevOps platform of the made-up Nordlicht Reisen GmbH, first as a design with reasoned decisions, then as an implementation with a repository, pipeline, identity without a secret, checks and monitoring.

At the end you have worked through every area of the exam as a design question and as an exercise and designed and built a whole delivery chain. You check the final project yourself against a list.
